csdb =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 11.11.10.101)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = csdb)
    )
  )


csdbs =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 11.11.10.108)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 11.11.10.109)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = csdb)(UR=A)
    )
  )

出现了通道异常终止的错误,根本原因是在执行rman命令时连接主库配置的tns服务名不是指向单实例

修改网络服务名:

csdb =

    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 11.11.10.101)(PORT = 1521))
    )

再次执行复制命令

从上面的查询结果可以看到SSL: Not in use,have_ssl和have_openssl为DISABLED,这说明实际上是没有启用ssl。

这是因为通过执行mysql_ssl_rsa_setup命令产生的pem文件的权限为root用户而不是mysql用户造成的,将这些pem文件的权限修改为mysql用户与组 权限不要太大,只用户权限为rw,组与其它用户需要r权限

在不指定ssl密钥时就不能登录了

[mysql@localhost ~]$ mysql -h 10.11.13.19 -P 3306 -u jy -p123
mysql: [Warning] Using a password on the command line interface can be insecure.

指定ssl密钥进行登录

[mysql@localhost ~]$  mysql -h 10.11.13.19 -P 3306 -u jy -p123 --ssl-cert=/mysqldata/mysql/client-cert.pem --ssl-key=/mysqldata/mysql/client-key.pem

The script will setup SSH connectivity from the host 18c1 to all
the remote hosts. After the script is executed, the user can use SSH to run
commands on the remote hosts or copy files between this host 18c1
and the remote hosts without being prompted for passwords or confirmations.

NOTE 1:
As part of the setup procedure, this script will use ssh and scp to copy
files between the local host and the remote hosts. Since the script does not
store passwords, you may be prompted for the passwords during the execution of
the script whenever ssh or scp is invoked.

NOTE 2:
AS PER SSH REQUIREMENTS, THIS SCRIPT WILL SECURE THE USER HOME DIRECTORY
AND THE .ssh DIRECTORY BY REVOKING GROUP AND WORLD WRITE PRIVILEGES TO THESE
directories.

Confirmation provided on the command line

The user chose yes
Please specify if you want to specify a passphrase for the private key this script will create for the local host. Passphrase is used to encrypt the private key and makes SSH much more secure. Type 'yes' or 'no' and then press enter. In case you press 'yes', you would need to enter the passphrase whenever the script executes ssh or scp. no 
The estimated number of times the user would be prompted for a passphrase is 4. In addition, if the private-public files are also newly created, the user would have to specify the passphrase on one additional occasion.

Verifying SSH setup
===================
The script will now run the date command on the remote nodes using ssh
to verify if ssh is setup correctly. IF THE SETUP IS CORRECTLY SETUP,
THERE SHOULD BE NO OUTPUT OTHER THAN THE DATE AND SSH SHOULD NOT ASK FOR
PASSWORDS. If you see any output other than date or are prompted for the
password, ssh is not setup correctly and you will need to resolve the
issue and set up ssh again.
The possible causes for failure could be:
1. The server settings in /etc/ssh/sshd_config file do not allow ssh
for user grid.
2. The server may have disabled public key based authentication.
3. The client public key on the server may be outdated.
4. ~grid or ~grid/.ssh on the remote host may not be owned by grid.
5. User may not have passed -shared option for shared remote users or
may be passing the -shared option for non-shared remote users.
6. If there is output in addition to the date, but no password is asked,
it may be a security alert shown as part of company policy. Append the
additional text to the /sysman/prov/resources/ignoreMessages.txt file.

MySQL 拷贝一个InnoDB分区表到另一个实例

拷贝一个InnoDB分区表到另一个实例
这个过程演示了如何将一个InnoDB分区表从一个正在运行的MySQL服务器实例复制到另一个正在运行的实例。同样的过程,只要稍微做些调整,就可以在同一个实例上对InnoDB分区表执行完全恢复。

1.在源实例上,如果不存在分区表,则创建分区表。在下面的例子中,创建了一个包含三个分区(p0, p1, p2)的表

mysql> use test;
Database changed
mysql> create table t1(i int) engine=innodb partition by key(i) partitions 3;
Query OK, 0 rows affected (0.38 sec)

mysql> insert into t1 values(1),(2),(3),(4),(5),(6),(7),(8),(9);
Query OK, 9 rows affected (0.03 sec)
Records: 9  Duplicates: 0  Warnings: 0
mysql> select * from t1;
+------+
| i    |
+------+
|    4 |
|    5 |
|    1 |
|    6 |
|    7 |
|    2 |
|    3 |
|    8 |
|    9 |
+------+
9 rows in set (0.00 sec)

在/mysqldata/mysql/test目录中,对于三个分区都有一个单独的表空间(.ibd)文件:

3.在目标实例上,丢弃分区表的表空间。(在将表空间导入目标实例之前,必须丢弃附加到接收表的表空间。)

mysql> alter table t1 discard tablespace;
Query OK, 0 rows affected (0.09 sec)

组成分区表表空间的三个.ibd文件从/mysqldata/mysql/tes目录中被丢弃,留下以下文件

-rw-r-----. 1 mysql mysql   375 3月  16 16:00 t1#P#p2.cfg

FLUSH TABLES……FOR EXPORT语句确保对指定表的更改已刷新到磁盘,以便在实例运行时可以进行二进制表拷贝。当运行FLUSH TABLES … FOR EXPORT时,InnoDB会在数据库目录中为表的表空间文件生成一个.cfg元数据文件。.cfg文件中包含导入表空间文件时验证模式的元数据。FLUSH TABLES … FOR EXPORT只能在表上运行,而不能在单独的表分区上运行。

5.将.ibd和.cfg文件从源实例数据库目录复制到目标实例数据库目录。例如

[root@localhost test]# scp t1*.{ibd,cfg} mysql@192.168.1.243:/mysqldata/mysql/test/
mysql@192.168.1.243's password:

6.在源实例上,使用unlock tables语句来释放由flush tables … for export所获取的锁:

mysql> unlock tables;
Query OK, 0 rows affected (0.00 sec)

在源实例上释放锁时,会向mysql日志文件写入删除.cfg文件的信息:

2022-03-16T08:08:27.653352Z 10 [Note] InnoDB: Deleting the meta-data file './test/t1#P#p0.cfg'

2022-03-16T08:08:27.654256Z 10 [Note] InnoDB: Resuming purge

7.在目标实例上,导入表空间:

mysql> select * from t1;
ERROR 1814 (HY000): Tablespace has been discarded for table 't1'
mysql> alter table t1 discard tablespace;
Query OK, 0 rows affected (0.09 sec)

MySQL 传输表空间

将file-per-table表空间复制到另一个实例
如何将一个file-per-table表空间从一个MySQL实例复制到另一个实例中,也就是众所周知的可传输表空间特性。

有很多原因可以解释为什么你可以将一个InnoDB文件表空间复制到不同的实例中:
.在不增加生产服务器额外负载的情况下运行报表。

.在新的从服务器上为表设置相同的数据

.在出现问题或错误后恢复表或分区的备份版本。

.作为一种比mysqldump命令导入更快的移动数据的方法。数据立即可用,而不需要重新插入和重建索引

.将每个file-per-table表空间移动到具有更适合系统需求的存储介质的服务器。例如,您可能希望在SSD设备上有繁忙的表,或者在高容量HDD设备上有大型表。

限制和使用说明
.只有当innodb_file_per_table设置为ON(默认设置)时,才可以拷贝表空间。驻留在共享系统表空间中的表不能被静默。

.当一个表被静默时,只允许在受影响的表上执行只读事务

.在导入表空间时,页面大小必须与导入实例的页面大小相匹配。

.当foreign_key_checks设置为1时,对于父-子(主-外键)关系的表空间不支持DISCARD TABLESPACE。在丢弃父-子表的表空间之前,设置foreign_key_checks=0。分区InnoDB表不支持外键。

.ALTER TABLE……IMPORT TABLESPACE不会对导入的数据强制外键约束。如果表之间存在外键约束,那么所有表都应该在同一(逻辑)时间点导出。分区InnoDB表不支持外键。

.ALTER TABLE……IMPORT TABLESPACE 和 ALTER TABLE…IMPORT PARTITION…TABLESPACE不需要.cfg元数据文件来导入一个表空间。但是,如果导入时没有.cfg文件,则不会执行元数据检查,并且会发出类似于下面的警告:

Message: InnoDB: IO Read error: (2, No such file or directory) Error opening '.\
test\t.cfg', will attempt to import without schema verification
1 row in set (0.00 sec)

在期待没用模式不匹配的情况下,不使用.cfg文件进行导入可能会更方便。此外,在无法从.ibd文件收集元数据的崩溃恢复场景中,不需要.cfg文件就可以导入。

.由于.cfg元数据文件的限制,当为分区表导入表空间文件时,不会对分区类型或分区定义差异报告模式不匹配。列差异被报告。

.当在子分区表上运行ALTER TABLE … DISCARD PARTITION … TABLESPACE和ALTER TABLE … IMPORT PARTITION … TABLESPACE,分区和子分区表名都是允许的。当指定分区名时,该分区的子分区将包含在操作中。

.如果两个实例都有GA(通用可用性)状态,并且它们的版本在同一系列可以从另一个MySQL服务器实例导入表空间文件。否则,该文件必须是在导入它的同一个服务器实例上所创建

.在复制场景中,innodb_file_per_table必须在主节点和从节点上都设置为ON。

.在Windows环境下,InnoDB内部存储数据库、表空间和表名时使用小写字母。为了避免在区分大小写的操作系统(如Linux、UNIX)上的导入问题,请在创建数据库、表空间和表时使用小写名称。一种方便的方法是在创建数据库、表空间或表之前,在my.cnf或my.ini文件的[mysqld]部分中添加下面这一行:

[mysqld]
lower_case_table_names=1

.alter table … discard tablespace和alter table … import tabelspace不支持属于InnoDB通用表空间中的表。

.InnoDB表的默认行格式可以通过innodb_default_row_format配置选项进行配置。如果导入的表没有明确定义行格式(ROW_FORMAT),或者使用了ROW_FORMAT=DEFAULT,那么如果源实例上的innodb_default_row_format设置与目标实例上的innodb_default_row_format设置不一致,可能会导致模式不匹配错误

.在使用InnoDB表空间加密特性导出加密的表空间时,InnoDB除了生成一个.cfg元数据文件外,还会生成一个.cfp文件。在目标实例上执行ALTER TABLE…IMPORT TABLESPACE之前,必须将.cfp文件与.cfg文件和表空间文件一起复制到目标实例中。cfp文件包含一个传输密钥和一个加密的表空间密钥。在导入时,InnoDB使用传输密钥来解密表空间密钥。

传输表空间示例
例如1:复制一个InnoDB表到另一个实例
这个过程演示了如何将一个普通的InnoDB表从一个正在运行的MySQL服务器实例复制到另一个正在运行的实例。可以使用相同的过程在相同的实例上执行全表恢复,只是做了一些小小的调整。
1. 在源实例上,如果不存在表,则创建一个表:

mysql> use test;
Database changed
mysql> create table t(c1 int) engine=innodb;
Query OK, 0 rows affected (0.12 sec)

mysql> insert into t values(1);
Query OK, 1 row affected (0.16 sec)

2.在目标实例上,如果不存在表,则创建表:

mysql> use test;
Database changed
mysql> create table t(c1 int) engine=innodb;
Query OK, 0 rows affected (0.09 sec)

3.在目标实例上,丢弃现有的表空间。(在导入表空间之前,InnoDB必须丢弃连接到接收表空间的表空间。)

4.在源实例上,运行FLUSH TABLES…FOR EXPORT将暂停表并创建.cfg元数据文件

mysql> flush tables t for export;
Query OK, 0 rows affected (0.00 sec)


[mysql@localhost test]$ ls -lrt

-rw-r-----. 1 mysql mysql   371 3月  15 17:00 t.cfg

在InnoDB数据目录下创建元数据(.cfg)
注意:FLUSH TABLES …… FOR EXPORT在MySQL 5.6.6版本中可用。该语句确保对指定表的更改已刷新到磁盘,以便在实例运行时可以生成二进制表副本。当FLUSH TABLES … FOR EXPORT时,InnoDB会在表所在的数据库目录中生成一个.cfg文件。cfg文件中包含导入表空间文件时用于模式验证的元数据。

5.将.ibd文件和.cfg元数据文件从源实例复制到目标实例

[mysql@localhost test]$ scp t.{ibd,cfg} mysql@192.168.1.243:/mysqldata/mysql/test/
mysql@192.168.1.243's password:
t.ibd                                                                                                                                                                                                    100%   96KB  96.0KB/s   00:00
t.cfg                                                                                                                                                                                                    100%  371     0.4KB/s   00:00
[mysql@localhost test]$

在释放共享锁之前必须复制.ibd与.cfg文件。

6.在源实例上,使用unlock tables语句来释放由flush tables … for export所获取的锁:

mysql> unlock tables;
Query OK, 0 rows affected (0.00 sec)

7.在目标实例上,导入表空间:
mysql> alter table t import tablespace;
Query OK, 0 rows affected (0.15 sec)

mysql> desc t;
+-------+---------+------+-----+---------+-------+
| Field | Type    | Null | Key | Default | Extra |
+-------+---------+------+-----+---------+-------+
| c1    | int(11) | YES  |     | NULL    |       |
+-------+---------+------+-----+---------+-------+
1 row in set (0.00 sec)

mysql> select * from t;
+------+
| c1   |
+------+
|    1 |
+------+
1 row in set (0.00 sec)

可以看到表t从一个实例迁移到另一个实例上。

DM8 配置DMDSC主备环境(rac到单节点 )

配置DMDSC主备环境
DMDSC主备环境搭建和单节点主备环境搭建步骤类似,区别主要在于首先要准备DMDSC集群环境。

配置说明
DMDSC集群可以作为主库,也可以作为实时备库、即时备库或者异步备库,当DMDSC集群作为备库配置在数据守护系统中时,要将DMDSC集群作为一个整体配置在源库的dmarch.ini中,也就是DMDSC集群所有节点要配置在同一个归档配置项中,每个节点实例名以“/”分隔开来。

假如DMDSC集群有两个节点GRP1_RT_DSC01和GRP1_RT_DSC02,DMDSC集群要作为备库进行配置,其源库为A,则要在A的dmarch.ini文件中增加DMDSC集群的归档配置,这里以实时备库为例说明如下:

[ARCHIVE_REALTIME1]
ARCH_TYPE = REALTIME
ARCH_DEST = GRP1_RT_DSC01/GRP1_RT_DSC02

如果DMDSC集群要作为即时备库或者异步备库来配置,ARCH_DEST的配置方式和示例中是相同的,ARCH_TYPE则要分别替换为TIMELY或者ASYNC,中括号内的配置项名称中包含的归档类型也建议修改和ARCH_TYPE一致。

环境说明
下面以DMDSC集群和单节点之间搭建实时主备环境为例,对搭建步骤进行说明。

下列机器事先都安装了DM8,安装路径为’/dm8’,执行程序保存在’/dm8/bin’目录中,数据存放路径为’/dm8/data’。

各主备库的实例名建议采用“组名_守护环境_序号”的方式命名,方便按组区分不同实例,注意总长度不能超过16。本示例中组名为“GRP1”,配置为实时主备,主库DMDSC集群的三个节点实例名分别命名为“rac1”、“rac2”,备库命名为“rac_st”。

本次部署为2节点DSC为主库,单机达梦为物理备库

IP规划:

主机名	  服务ip	        心跳ip	        实例名	节点用途
dm8rac1	  10.10.13.201	10.10.13.201	rac1	rac节点1
dm8rac2	  10.10.13.202	10.10.13.202	rac2	rac节点2
dm8rac_st 10.10.13.227	10.10.13.227	rac_st	rac备库

端口规划:

实例名    port_num    mal_inst_dw_port    mal_host          mal_port    mal_dw_port  CSS端口	ASM端口	ASM的MAL端口	DCR检查实例端口

[root@gbase ~]# setenforce 0
[root@gbase ~]# sed -i s:^SELINUX=.*$:SELINUX=disabled:g /etc/selinux/config
[root@gbase ~]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

2、修改主机名

[root@gbase ~]# hostname dm8rac1
[root@gbase ~]# sed -i s:^HOSTNAME=.*$:HOSTNAME=dm8rac1:g /etc/sysconfig/network
[root@gbase ~]# echo "
 > 10.10.13.201   dm8rac1
 > 10.10.13.202   dm8rac2" >> /etc/hosts
[root@gbase ~]# cat  /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

 10.10.13.201   dm8rac1
 10.10.13.202   dm8rac2


[root@gbase ~]# hostname dm8rac2
[root@gbase ~]# sed -i s:^HOSTNAME=.*$:HOSTNAME=dm8rac2:g /etc/sysconfig/network
[root@gbase ~]#
[root@gbase ~]# echo "
>  10.10.13.201   dm8rac1
>  10.10.13.202   dm8rac2" >> /etc/hosts
[root@gbase ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

 10.10.13.201   dm8rac1
 10.10.13.202   dm8rac2

三、 安装达梦软件

3.1检查Linux(Unix)系统信息

[root@dm8rac1 ~]# getconf LONG_BIT
64

[root@dm8rac2 ~]# getconf LONG_BIT
64

查询操作系统release信息

[root@dm8rac1 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.8 Beta (Maipo)

[root@dm8rac2 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.8 Beta (Maipo)

3.2创建安装用户
为了减少对操作系统的影响,用户不应该以root系统用户来安装和运行DM。用户可以在安装之前为DM创建一个专用的系统用户。
1. 创建安装用户组dinstall。

[root@dm8rac1 ~]# groupadd dinstall

[root@dm8rac2 ~]# groupadd dinstall

2. 创建安装用户dmdba。

[root@dm8rac1 ~]# useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba

[root@dm8rac2 ~]# useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba

3. 初始化用户密码。

[root@dm8rac1 ~]# passwd dmdba
Changing password for user dmdba.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

[root@dm8rac2 ~]# passwd dmdba
Changing password for user dmdba.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

3.3 Linux(Unix)下检查操作系统限制
在Linux(Unix)系统中,因为ulimit命令的存在,会对程序使用操作系统资源进行限制。为了使DM能够正常运行,建议用户检查当前安装用户的ulimit参数。

运行ulimit -a进行查询。如下图所示:

[root@dm8rac1 ~]# ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 31152
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 31152
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

[root@dm8rac2 ~]# ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 31152
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 31152
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

参数使用限制:
1.data seg size
data seg size (kbytes, -d)
建议用户设置为1048576(即1GB)以上或unlimited(无限制),此参数过小将导致数据库启动失败。
2. file size
file size(blocks, -f)
建议用户设置为unlimited(无限制),此参数过小将导致数据库安装或初始化失败。
3. open files
open files(-n)
建议用户设置为65536以上或unlimited(无限制)。
4.virtual memory
virtual memory (kbytes, -v)
建议用户设置为1048576(即1GB)以上或unlimited(无限制),此参数过小将导致数据库启动失败。

如果用户需要为当前安装用户更改ulimit的资源限制,请修改文件/etc/security/limits.conf。

[root@dm8rac1 ~]# vi /etc/security/limits.conf
dmdba soft data unlimited
dmdba hard data unlimited
dmdba soft fsize unlimited
dmdba hard fsize unlimited
dmdba soft nofile 65536

3.4.检查系统内存与存储空间
1.检查内存
为了保证DM的正确安装和运行,要尽量保证操作系统至少1GB的可用内存(RAM)。如果可用内存过少,可能导致DM安装或启动失败。用户可以
使用以下命令检查操作内存:
#获取内存总大小

[root@dm8rac1 ~]# grep MemTotal /proc/meminfo
MemTotal:        8009068 kB

[root@dm8rac12 ~]# grep MemTotal /proc/meminfo
MemTotal:        8009068 kB

#获取交换分区大小

[root@dm8rac1 ~]# grep SwapTotal /proc/meminfo
SwapTotal:       8257532 kB

[root@dm8rac2 ~]# grep SwapTotal /proc/meminfo
SwapTotal:       8257532 kB

#获取内存使用详情

[root@dm8rac1 ~]# free -g
              total        used        free      shared  buff/cache   available
Mem:              7           0           6           0           0           6
Swap:             7           0           7

[root@dm8rac2 ~]# free -g
              total        used        free      shared  buff/cache   available
Mem:              7           0           6           0           0           6
Swap:             7           0           7

2.检查存储空间
1) DM完全安装需要1GB的存储空间,用户需要提前规划好安装目录,预留足够的存储空间。用户在DM安装前也应该为数据库实例预留足够的存储空间,规划好数据路径和备份路径。用户可使用以下命令检查存储空间:
#查询目录/dm8可用空间

[root@dm8rac1 ~]# mkdir /dm8
[root@dm8rac1 ~]# chown -R dmdba:dinstall /dm8
[root@dm8rac1 ~]# chmod -R 775 /dm8

[root@dm8rac2 ~]# mkdir /dm8
[root@dm8rac2 ~]# chown -R dmdba:dinstall /dm8
[root@dm8rac2 ~]# chmod -R 775 /dm8

[root@dm8rac1 ~]# df -h /dm8
Filesystem             Size  Used Avail Use% Mounted on
/dev/mapper/rhel-root   48G  5.6G   43G  12% /


[root@dm8rac2 ~]# df -h /dm8
Filesystem             Size  Used Avail Use% Mounted on
/dev/mapper/rhel-root   48G  5.6G   43G  12% /

2) DM安装程序在安装时将产生临时文件,临时文件需要1GB的存储空间,临时文件目录默认为/tmp。用户可以使用以下命令检查存储空间。
如下图所示:

[root@dm8rac1 ~]# df -h /tmp
Filesystem             Size  Used Avail Use% Mounted on
/dev/mapper/rhel-root   48G  5.6G   43G  12% /


[root@dm8rac2 ~]# df -h /tmp
Filesystem             Size  Used Avail Use% Mounted on
/dev/mapper/rhel-root   48G  5.6G   43G  12% /

3.5.安装DM
创建目录/soft/dmsoft用来存储挂载iso文件后来显示软件包中的文件

[root@dm8rac1 ~]# cd /soft
[root@dm8rac1 soft]# unzip dm8_20211021_x86_rh6_64_ent.zip

-r-xr-xr-x. 1 root root 806320703 Oct 21 14:11 DMInstall.bin

在/soft/dmsoft目录下存在DMInstall.bin文件, DMInstall.bin文件就是DM的安装程序。在运行安装程序前,需要赋予DMInstall.bin文件执行权限。具体命令如下所示:

[root@dm8rac1 dmsoft]# chmod 755  DMInstall.bin
chmod: changing permissions of ‘DMInstall.bin’: Read-only file system


[root@dm8rac2 dmsoft]# chmod 755  DMInstall.bin
chmod: changing permissions of ‘DMInstall.bin’: Read-only file system

在现实中,许多Linux(Unix)操作系统上是没有图形化界面的,为了使DM能够在这些操作系统上顺利安装,DM提供了命令行的安装方式。在终端进入到安装程序所在文件夹,执行以下命令进行命令行安装:

[dmdba@dm8rac1 dmsoft]$ ./DMInstall.bin -i

10737418240
[root@dm8rac6 ~]# blockdev --getsize64 /dev/raw/raw6
10737418240

五.配置dmdcr_cfg.ini文件
在2个节点的/dm8/data目录下创建配置文件dmdcr_cfg.ini,在文件中添加如下内容:

[dmdba@dm8rac1 ~]$ mkdir /dm8/data

[dmdba@dm8rac2 ~]$ mkdir /dm8/data

[dmdba@dm8rac1 data]$ vi dmdcr_cfg.ini

六.使用 DMASMCMD 工具初始化(任意一节点执行)

[dmdba@dm8rac1 ~]$ dmasmcmd
DMASMCMD V8

Used time: 00:00:01.089.
ASM>

七.准备DMASM 的 MAL 配置文件
在2个节点的/dm8/data目录下创建 DMASM 的 MAL 配置文件(命名为 dmasvrmal.ini),使用 DMASM 的所有节点都要配置,内容完全一样。

[dmdba@dm8rac1 data]$ vi dmasvrmal.ini
[MAL_INST1]
MAL_INST_NAME = ASM1
MAL_HOST = 10.10.13.201
MAL_PORT = 5242

[MAL_INST2]
MAL_INST_NAME = ASM2
MAL_HOST = 10.10.13.202
MAL_PORT = 5242


[dmdba@dm8rac2 data]$ vi dmasvrmal.ini
[MAL_INST1]
MAL_INST_NAME = ASM1
MAL_HOST = 10.10.13.201
MAL_PORT = 5242

[MAL_INST2]
MAL_INST_NAME = ASM2
MAL_HOST = 10.10.13.202
MAL_PORT = 5242

八.准备dmdcr.ini 配置文件
dmdcr.ini 是 dmcss、dmasmsvr、dmasmtool 工具的输入参数。记录了当前节点序列号以及 DCR 磁盘路径。在2个节点的/dm/dmdbms/data目录下创建dmdcr.ini 配置文件,dmdcr_path 相同,dmasvrmal.ini 文件内容也相同,dmdcr_seqo 分别为 0 和 1。
节点 1:

[dmdba@dm8rac1 data]$ vi dmdcr.ini
DMDCR_PATH = /dev/raw/raw1
DMDCR_MAL_PATH =/dm8/data/dmasvrmal.ini
DMDCR_SEQNO = 0

#ASM
DMDCR_ASM_RESTART_INTERVAL = 10
DMDCR_ASM_STARTUP_CMD = /dm8/bin/dmasmsvr dcr_ini=/dm8/data/dmdcr.ini

#DB
DMDCR_DB_RESTART_INTERVAL = 30
DMDCR_DB_STARTUP_CMD = /dm8/bin/dmserver path=/dm8/data/config/rac1/dm.ini dcr_ini=/dm8/data/dmdcr.ini


节点2:

[dmdba@dm8rac2 data]$ vi dmdcr.ini
DMDCR_PATH = /dev/raw/raw1
DMDCR_MAL_PATH =/dm8/data/dmasvrmal.ini
DMDCR_SEQNO = 1

#ASM
DMDCR_ASM_RESTART_INTERVAL = 10
DMDCR_ASM_STARTUP_CMD = /dm8/bin/dmasmsvr dcr_ini=/dm8/data/dmdcr.ini

#DB
DMDCR_DB_RESTART_INTERVAL = 30
DMDCR_DB_STARTUP_CMD = /dm8/bin/dmserver path=/dm8/data/config/rac2/dm.ini dcr_ini=/dm8/data/dmdcr.ini

九.启动DMCSS、DMASM 服务程序
1、注册 DMCSS和DMASM服务
节点一:

[root@dm8rac1 ~]# /dm8/script/root/dm_service_installer.sh -t dmcss -dcr_ini /dm8/data/dmdcr.ini -p rac1
Created symlink from /etc/systemd/system/multi-user.target.wants/DmCSSServicerac1.service to /usr/lib/systemd/system/DmCSSServicerac1.service.
Finished to create the service (DmCSSServicerac1)
[root@dm8rac1 ~]# /dm8/script/root/dm_service_installer.sh -t dmasmsvr -dcr_ini /dm8/data/dmdcr.ini -p rac1 -y DmCSSServicerac1
Created symlink from /etc/systemd/system/multi-user.target.wants/DmASMSvrServicerac1.service to /usr/lib/systemd/system/DmASMSvrServicerac1.service.
Finished to create the service (DmASMSvrServicerac1)

节点二:

[root@dm8rac2 ~]# /dm8/script/root/dm_service_installer.sh -t dmcss -dcr_ini /dm8/data/dmdcr.ini -p rac2
Created symlink from /etc/systemd/system/multi-user.target.wants/DmCSSServicerac2.service to /usr/lib/systemd/system/DmCSSServicerac2.service.
Finished to create the service (DmCSSServicerac2)
[root@dm8rac2 ~]# /dm8/script/root/dm_service_installer.sh -t dmasmsvr -dcr_ini /dm8/data/dmdcr.ini -p rac2 -y DmCSSServicerac2
Created symlink from /etc/systemd/system/multi-user.target.wants/DmASMSvrServicerac2.service to /usr/lib/systemd/system/DmASMSvrServicerac2.service.
Finished to create the service (DmASMSvrServicerac2)

2、启动DMCSS和DMASM服务
节点一

[root@dm8rac1 ~]# service DmCSSServicerac1 start
Redirecting to /bin/systemctl start DmCSSServicerac1.service
[root@dm8rac1 ~]# ps -ef | grep dmdba
root      2952  2618  0 16:28 pts/0    00:00:00 su - dmdba
dmdba     2953  2952  0 16:28 pts/0    00:00:00 -bash
dmdba     3468     1  0 16:48 ?        00:00:00 /dm8/bin/dmcss dcr_ini=/dm8/data/dmdcr.ini
dmdba     3492     1  0 16:49 ?        00:00:00 /dm8/bin/dmasmsvr dcr_ini=/dm8/data/dmdcr.ini
root      3504  3205  0 16:49 pts/1    00:00:00 grep --color=auto dmdba

节点二

[root@dm8rac2 ~]# service DmCSSServicerac2 start
Redirecting to /bin/systemctl start DmCSSServicerac2.service
[root@dm8rac2 ~]# ps -ef | grep dmdba
root      2952  2619  0 16:28 pts/0    00:00:00 su - dmdba
dmdba     2953  2952  0 16:28 pts/0    00:00:00 -bash
dmdba     3456     1  0 16:49 ?        00:00:00 /dm8/bin/dmcss dcr_ini=/dm8/data/dmdcr.ini
dmdba     3480     1  1 16:49 ?        00:00:00 /dm8/bin/dmasmsvr dcr_ini=/dm8/data/dmdcr.ini
root      3496  3193  0 16:49 pts/1    00:00:00 grep --color=auto dmdba

css 服务启动后会自动拉起asm服务,因为在dmdcr.ini文件中配置自动拉起ASM和DB的操作。

十、创建DMASM磁盘组
在任意节点使用 dmasmtool 工具创建 DMASM 磁盘组。

[dmdba@dm8rac1 data]$ dmasmtool DCR_INI=/dm8/data/dmdcr.ini
DMASMTOOL V8
ASM>create diskgroup 'DMLOG' asmdisk '/dev/raw/raw3'
Used time: 428.934(ms).
ASM>create diskgroup 'DMDATA' asmdisk '/dev/raw/raw4'
Used time: 284.431(ms).
ASM>

十一、准备dminit.ini 配置文件
在2个节点的/dm8/data目录下创建 dminit.ini 配置文件,添加如下内容。 在2个节点都创建。

[dmdba@dm8rac1 data]$ vi dminit.ini
db_name = rac
system_path = +DMDATA/data
system = +DMDATA/data/rac/system.dbf
system_size = 128
roll = +DMDATA/data/rac/roll.dbf
roll_size = 128
main = +DMDATA/data/rac/main.dbf
main_size = 128
ctl_path = +DMDATA/data/rac/dm.ctl
ctl_size = 8
log_size = 256
dcr_path = /dev/raw/raw1 #dcr 磁盘路径,目前不支持 asm,只能是裸设备
dcr_seqno = 0
auto_overwrite = 1

[RAC1] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应
config_path = /dm8/data/config/rac1
port_num = 5236
mal_host = 10.10.13.201
mal_port = 5238
log_path = +DMLOG/log/rac0_log01.log
log_path = +DMLOG/log/rac0_log02.log

[RAC2] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应
config_path = /dm8/data/config/rac2
port_num = 5236
mal_host = 10.10.13.202
mal_port = 5238
log_path = +DMLOG/log/rac1_log01.log
log_path = +DMLOG/log/rac1_log02.log


[dmdba@dm8rac2 data]$ vi dminit.ini
db_name = rac
system_path = +DMDATA/data
system = +DMDATA/data/rac/system.dbf
system_size = 128
roll = +DMDATA/data/rac/roll.dbf
roll_size = 128
main = +DMDATA/data/rac/main.dbf
main_size = 128
ctl_path = +DMDATA/data/rac/dm.ctl
ctl_size = 8
log_size = 256
dcr_path = /dev/raw/raw1 #dcr 磁盘路径,目前不支持 asm,只能是裸设备
dcr_seqno = 0
auto_overwrite = 1

[RAC1] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应
config_path = /dm8/data/config/rac1
port_num = 5236
mal_host = 10.10.13.201
mal_port = 5238
log_path = +DMLOG/log/rac0_log01.log
log_path = +DMLOG/log/rac0_log02.log

[RAC2] #inst_name 跟 dmdcr_cfg.ini 中 DB 类型 group 中 DCR_EP_NAME 对应
config_path = /dm8/data/config/rac2
port_num = 5236
mal_host = 10.10.13.202
mal_port = 5238
log_path = +DMLOG/log/rac1_log01.log
log_path = +DMLOG/log/rac1_log02.log

十二、使用dminit初始化数据库
在任意节点启动 dminit 工具初始化数据库。dminit 执行完成后,会在 config_path 目录(/dm8/data/config/rac1 和/dm8/data/config/rac2)下生成配置文件 dm.ini 和 dmmal.ini。

[dmdba@dm8rac1 data]$ dminit control=/dm8/data/dminit.ini
initdb V8
db version: 0x7000c
file dm.key not found, use default license!
License will expire on 2022-10-21
Normal of FAST
Normal of DEFAULT
Normal of RECYCLE
Normal of KEEP
Normal of ROLL

 log file path: +DMLOG/log/rac0_log01.log


 log file path: +DMLOG/log/rac0_log02.log


 log file path: +DMLOG/log/rac1_log01.log


 log file path: +DMLOG/log/rac1_log02.log

write to dir [+DMDATA/data/rac].
create dm database success. 2022-02-25 16:59:26

将节点一上的/dm8/data/config中的rac2配置目录复制到节点二:

[dmdba@dm8rac1 config]$ scp -r rac2 110.10.13.202:/dm8/data/config/
^C[dmdba@dm8rac1 config]$ scp -r rac2 10.10.13.202:/dm8/data/config/

十三、启动数据库服务器
1、在2个节点分别注册DM 数据库服务:
节点一:

[root@dm8rac1 ~]# /dm8/script/root/dm_service_installer.sh -t dmserver -dm_ini /dm8/data/config/rac1/dm.ini -dcr_ini /dm8/data/dmdcr.ini -p rac1 -y DmASMSvrServicerac1
Created symlink from /etc/systemd/system/multi-user.target.wants/DmServicerac1.service to /usr/lib/systemd/system/DmServicerac1.service.
Finished to create the service (DmServicerac1)

节点二:

[root@dm8rac2 ~]# /dm8/script/root/dm_service_installer.sh -t dmserver -dm_ini /dm8/data/config/rac2/dm.ini -dcr_ini /dm8/data/dmdcr.ini -p rac2 -y DmASMSvrServicerac2
Created symlink from /etc/systemd/system/multi-user.target.wants/DmServicerac2.service to /usr/lib/systemd/system/DmServicerac2.service.
Finished to create the service (DmServicerac2)

这里可以手动启动数据库服务来启动数据库,也可以重启CSS服务来启动数据库,因为配置CSS会自动拉起数据库

DSC+单机的DW部署
为DSC集群配置实时备机(单机),组成数据守护集群(DW)

配置DSC集群监视器
任意节点新建监视器配置文件,执行以下命令:

[dmdba@dm8rac1 data]$ vi dmcssm.ini
#和 dmdcr_cfg.ini 中的 DCR_OGUID 保持一致
CSSM_OGUID = 63635
#配置所有 CSS 的连接信息,
#和 dmdcr_cfg.ini 中 CSS 配置项的 DCR_EP_HOST 和 DCR_EP_PORT 保持一致
CSSM_CSS_IP = 10.10.13.201:5240
CSSM_CSS_IP = 10.10.13.202:5240
CSSM_LOG_PATH =/dm8/dmcssm/log #监视器日志文件存放路径
CSSM_LOG_FILE_SIZE = 32 #每个日志文件最大 32 MB
CSSM_LOG_SPACE_LIMIT = 0 #不限定日志文件总占用空间

启动监视器,dmdba 用户执行,

DM8动态增加读写分离集群节点

动态增加读写分离集群节点
配置读写分离集群
下列机器事先都安装了DM,安装路径为’/dm8’,执行程序保存在’/dm8/bin’目录中,数据存放路径为’/dm8/data’。

各主备库的实例名建议采用“组名_守护环境_序号”的方式命名,方便按组区分不同实例,注意总长度不能超过16。本示例中组名为“GRP1”,配置为读写分离集群,主库命名为“jy1”,备库分别命名为“jy2”和“jy3”。

配置操作
一.主库
配置dm.ini文件,配置以下参数

INSTANCE_NAME = jy1
PORT_NUM = 5236                             #数据库实例监听端口
DW_INACTIVE_INTERVAL = 60                   #接收守护进程消息超时时间

RLOG_SEND_APPLY_MON = 64                    #统计最近64次的日志发送信息

配置dmmal.ini文件
配置MAL系统,各主备库的dmmal.ini配置必须完全一致,MAL_HOST使用内部网络IP,MAL_PORT与dm.ini中PORT_NUM使用不同的端口值,MAL_DW_PORT是各实例对应的守护进程之间,以及守护进程和监视器之间的通信端口,配置如下:

MAL_CHECK_INTERVAL = 5               #MAL链路检测时间间隔
MAL_CONN_FAIL_INTERVAL = 5           #判定MAL链路断开的时间

[MAL_INST1]

MAL_INST_DW_PORT = 5237              #实例监听守护进程TCP连接的端口

[MAL_INST2]
MAL_INST_NAME = jy2                  #实例名,和dm.ini中的INSTANCE_NAME一致
MAL_HOST = 10.10.13.214            #MAL系统监听TCP连接的IP地址
MAL_PORT = 5238                      #MAL系统监听TCP连接的端口
MAL_INST_HOST = 10.10.13.214       #实例的对外服务IP地址

MAL_DW_PORT = 5239
MAL_INST_DW_PORT = 5237

配置dmarch.ini
修改dmarch.ini,配置本地归档和即时归档。
除了本地归档外,其他归档配置项中的ARCH_DEST表示实例是Primary模式时,需要同步归档数据的目标实例名。当前实例jy1是主库,需要向即时备库jy2/jy3同步数据,因此即时归档的ARCH_DEST分别配置为jy2和jy3。

[ARCHIVE_TIMELY1]
ARCH_TYPE = TIMELY                 #即时归档类型
ARCH_DEST = jy2                    #即时归档目标实例名

启动命令行工具DIsql,登录备库修改数据库为Standby模式如果当前数据库不是normal模式,需要先修改dm.ini中ALTER_MODE_STATUS值为1,允许修改数据库模式,修改Standby模式成功后再改回为0。如果是normal模式,请忽略下面的第1步和第3步。

SQL>SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 1); ----第1步
SQL>alter database standby; ----第2步
SQL>SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 0); ----第3步

配置监视器
由于主库和即时备库的守护进程配置为自动切换模式,因此这里选择配置确认监视器。和普通监视器相比,确认监视器除了相同的命令支持外,在主库发生故障时,能够自动通知即时备库接管为新的主库,具有自动故障处理的功能。

修改dmmonitor.ini配置确认监视器,其中MON_DW_IP中的IP和PORT和dmmal.ini中的MAL_HOST和MAL_DW_PORT配置项保持一致。

MON_DW_CONFIRM = 1                          #确认监视器模式
MON_LOG_PATH = /dm8/data/log                #监视器日志文件存放路径
MON_LOG_INTERVAL = 60                       #每隔60s定时记录系统信息到日志文件
MON_LOG_FILE_SIZE = 32                      #每个日志文件最大32M
MON_LOG_SPACE_LIMIT = 0                     #不限定日志文件总占用空间
[GRP1]
MON_INST_OGUID = 222222                     #组GRP1的唯一OGUID值
                                            #以下配置为监视器到组GRP1的守护进程的连接信息,以“IP:PORT”的形式配置
                                            #IP对应dmmal.ini中的MAL_HOST,PORT对应dmmal.ini中的MAL_DW_PORT
MON_DW_IP = 10.10.13.213:5238
MON_DW_IP = 10.10.13.214:5238
MON_DW_IP = 10.10.13.215:5238


[dmdba@dm216 data]$ vi dmmonitor.ini
MON_DW_CONFIRM = 1
MON_LOG_PATH = /dm8/data/log
MON_LOG_INTERVAL = 60
MON_LOG_FILE_SIZE = 32
MON_LOG_SPACE_LIMIT = 0

[GRP1]
MON_INST_OGUID = 222222



MON_DW_IP = 10.10.13.213:5238
MON_DW_IP = 10.10.13.214:5238

接口说明

DM多种客户端接口都支持读写分离集群连接设置,以下说明客户端连接服务器时如何设置读写分离属性,详细可参考《DM8程序员手册》。4

JDBC接口
在JDBC连接串中增加了两个连接属性:
n rwSeparate 是否使用读写分离系统,默认0;取值(0不使用,1使用)。
n rwPercent 分发到主库的事务占主备库总事务的百分比,有效值0~100,默认值25。
dm.jdbc.driver.DmDriver
jdbc:dm://192.168.0.206:5236?rwSeparate=1&rwPercent=10

当需要进行系统扩容,希望系统运行不中断,或者影响运行的时间尽可能短,可通过动态增加集群节点的方式进行。下面举例对读写分离集群进行
动态增加节点。

INSTANCE_NAME = jy         #实例名总长度不能超过16
PORT_NUM = 5236            #数据库实例监听端口
DW_INACTIVE_INTERVAL = 60  #接收守护进程消息超时时间
ALTER_MODE_STATUS = 0      #不允许手工方式修改实例模式/状态
ENABLE_OFFLINE_TS = 2      #不允许备库OFFLINE表空间
MAL_INI = 1                #打开MAL系统
ARCH_INI = 1               #打开归档配置
RLOG_SEND_APPLY_MON = 64   #统计最近64次的日志重演信息

拷贝一份原系统dmmal.ini文件,并加上自己一项,最终配置如下:

Created symlink from /etc/systemd/system/multi-user.target.wants/DmWatcherServicejy4.service to /usr/lib/systemd/system/DmWatcherServicejy4.service.
Finished to create the service (DmWatcherServicejy4)

启动备库
以mount方式启动备库

[dmdba@dm8rw5 ~]$ dmserver /dm8/data/jy/dm.ini mount
file dm.key not found, use default license!

设置OGUID
启动命令行工具disql,登录备库设置OGUID值。

[dmdba@dm8rw5 jy]$ disql SYSDBA/SYSDBA@localhost:5236

Server[localhost:5236]:mode is primary, state is mount
login used time : 3.364(ms)
disql V8
SQL> sp_set_oguid(222222);
sp_set_oguid(222222);

used time: 7.912(ms). Execute id is 0.
SQL> SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 1);
DMSQL executed successfully
used time: 8.997(ms). Execute id is 1.
SQL> sp_set_oguid(222222);
DMSQL executed successfully
used time: 57.701(ms). Execute id is 2.

修改数据库模式
修改数据库为Standby模式:

SQL> alter database standby;
executed successfully
used time: 66.098(ms). Execute id is 0.
SQL> SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 0);
DMSQL executed successfully
used time: 8.720(ms). Execute id is 3.

动态添加MAL配置
需要分别连接原系统中每个实例单独执行:
1.允许手工修改服务器的模式和状态。

[dmdba@dm8rw1 ~]$ disql SYSDBA/SYSDBA@localhost:5236

Server[localhost:5236]:mode is primary, state is open
login used time : 2.628(ms)
disql V8
SQL> SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 1);
DMSQL executed successfully
used time: 36.203(ms). Execute id is 600.


[dmdba@dm8rw2 ~]$ disql SYSDBA/SYSDBA@localhost:5236

Server[localhost:5236]:mode is standby, state is open
login used time : 4.421(ms)
disql V8
SQL> SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 1);
DMSQL executed successfully
used time: 140.819(ms). Execute id is 0.

[dmdba@dm8rw3 ~]$ disql SYSDBA/SYSDBA@localhost:5236

Server[localhost:5236]:mode is standby, state is open
login used time : 4.246(ms)
disql V8
SQL> SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 1);
DMSQL executed successfully
used time: 127.831(ms). Execute id is 0

2.退出原系统所有守护进程。
注意守护进程退出后,需要等待对应实例dm.ini中配置的DW_INACTIVE_INTERVAL时间后才允许后续操作,否则未超过故障认定时间,服务器认为守护进程仍然处于活动状态,不允许手工修改服务器为mount状态。

[root@dm8rw1 ~]# service DmWatcherServicejy1 stop
Redirecting to /bin/systemctl stop DmWatcherServicejy1.service


[root@dm8rw2 ~]# service DmWatcherServicejy2 stop
Redirecting to /bin/systemctl stop DmWatcherServicejy2.service

[root@dm8rw3 ~]# service DmWatcherServicejy3 stop
Redirecting to /bin/systemctl stop DmWatcherServicejy3.service

3.修改数据库状态为MOUNT。

[dmdba@dm8rw1 ~]$ disql SYSDBA/SYSDBA@localhost:5236

Server[localhost:5236]:mode is primary, state is open
login used time : 2.628(ms)
disql V8
SQL> alter database mount;
executed successfully
used time: 47.587(ms). Execute id is 0.

disql V8
SQL> alter database mount;
executed successfully
used time: 37.954(ms). Execute id is 0.

4.重新修改ALTER_MODE_STATUS值为0,不允许手工修改服务器的模式和状态
jy1:

SQL> SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 0);
DMSQL executed successfully
used time: 8.305(ms). Execute id is 602.

jy2:

SQL> SP_SET_PARA_VALUE(1, 'ALTER_MODE_STATUS', 0);
DMSQL executed successfully

DMSQL executed successfully
used time: 0.585(ms). Execute id is 6.

动态添加归档配置
分别连接原系统中的所有实例(此时处于MOUNT状态),动态添加dmarch.ini中归档节点
jy1:

SQL> alter database add archivelog 'DEST=jy4, TYPE=TIMELY';
executed successfully
used time: 1.596(ms). Execute id is 0.

jy2:

SQL> alter database add archivelog 'DEST=jy4, TYPE=TIMELY';
executed successfully
used time: 1.199(ms). Execute id is 0.

jy3:

SQL> alter database add archivelog 'DEST=jy4, TYPE=TIMELY';
executed successfully
used time: 1.357(ms). Execute id is 0.

修改监视器dmmonitor.ini
在dmmonitor.ini中添加新增的备库jy4:

[dmdba@dm8rw4 ~]$ vi /dm8/data/dmmonitor.ini
MON_DW_CONFIRM = 1
MON_LOG_PATH = /dm8/data/log
MON_LOG_INTERVAL = 60
MON_LOG_FILE_SIZE = 32
MON_LOG_SPACE_LIMIT = 0

[GRP1]
MON_INST_OGUID = 222222



MON_DW_IP = 10.10.13.213:5239
MON_DW_IP = 10.10.13.214:5239
MON_DW_IP = 10.10.13.215:5239
MON_DW_IP = 10.10.13.226:5239

启动所有守护进程以及监视器
分别启动主库和备库(包括jy4)的所有守护进程,最后启动监视器。

DM8配置异步备库

配置异步备库
先搭建实时主备
下列机器事先都安装了DM,安装路径为’/dm8’,执行程序保存在’/dm8/bin’目录中,数据存放路径为’/dm8/data’。

各主备库的实例名建议采用“组名_守护环境_序号”的方式命名,方便按组区分不同实例,注意总长度不能超过16。本示例中组名为“GRP1”,配置为实时主备,主库命名为“hy1”,备库命名为“hy2”。

机器名     IP地址                  初始状态                         操作系统

配置操作
一.主库
配置dm.ini文件,配置以下参数:

配置dmmal.ini文件
配置MAL系统,各主备库的dmmal.ini配置必须完全一致,MAL_HOST使用内部网络IP,MAL_PORT与dm.ini中PORT_NUM使用不同的端口值,MAL_DW_PORT是各实例对应的守护进程之间,以及守护进程和监视器之间的通信端口,配置如下:

MAL_CHECK_INTERVAL = 5           #MAL链路检测时间间隔
MAL_CONN_FAIL_INTERVAL = 5       #判定MAL链路断开的时间

[MAL_INST1]
MAL_INST_NAME = HY1              #实例名,和dm.ini中的INSTANCE_NAME一致
MAL_HOST = 10.10.13.222          #MAL系统监听TCP连接的IP地址
MAL_PORT = 5237                  #MAL系统监听TCP连接的端口
MAL_INST_HOST = 10.10.13.222     #实例的对外服务IP地址
MAL_INST_PORT = 5236             #实例的对外服务端口,和dm.ini中的PORT_NUM一致
MAL_DW_PORT = 5238               #实例本地的守护进程监听TCP连接的端口
MAL_INST_DW_PORT = 5239          #实例监听守护进程TCP连接的端口

[MAL_INST2]
MAL_INST_NAME = HY2              #实例名,和dm.ini中的INSTANCE_NAME一致
MAL_HOST = 10.10.13.223          #MAL系统监听TCP连接的IP地址
MAL_PORT = 5237                  #MAL系统监听TCP连接的端口
MAL_INST_HOST = 10.10.13.223     #实例的对外服务IP地址
MAL_INST_PORT = 5236             #实例的对外服务端口,和dm.ini中的PORT_NUM一致
MAL_DW_PORT = 5238               #实例本地的守护进程监听TCP连接的端口
MAL_INST_DW_PORT = 5239          #实例监听守护进程TCP连接的端口

[dmdba@dm222 hy]$ vi dmmal.ini
MAL_CHECK_INTERVAL = 5
MAL_CONN_FAIL_INTERVAL = 5

[MAL_INST1]
MAL_INST_NAME = HY1
MAL_HOST = 10.10.13.222
MAL_PORT = 5237
MAL_INST_HOST = 10.10.13.222
MAL_INST_PORT = 5236
MAL_DW_PORT = 5238
MAL_INST_DW_PORT = 5239

[MAL_INST2]
MAL_INST_NAME = HY2
MAL_HOST = 10.10.13.223
MAL_PORT = 5237
MAL_INST_HOST = 10.10.13.223
MAL_INST_PORT = 5236
MAL_DW_PORT = 5238
MAL_INST_DW_PORT = 5239

配置dmarch.ini
修改dmarch.ini,配置本地归档和实时归档。
除了本地归档外,其他归档配置项中的ARCH_DEST表示实例是Primary模式时,需要同步归档数据的目标实例名。当前实例HY1是主库,需要向HY2(实时备库)同步数据,因此实时归档的ARCH_DEST配置为HY2。

[ARCHIVE_REALTIME]                                #实时归档
ARCH_TYPE = REALTIME                              #实时归档类型
ARCH_DEST = HY2                                   #实时归档目标实例名
[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL                                 #本地归档类型
ARCH_DEST = /dm8/data/hy/arch                     #本地归档文件存放路径
ARCH_FILE_SIZE = 128                              #单位Mb,本地单个归档文件最大值
ARCH_SPACE_LIMIT = 0                              #单位Mb,0表示无限制,范围1024~4294967294M

[dmdba@dm222 hy]$ vi dmarch.ini
[ARCHIVE_REALTIME]
ARCH_TYPE = REALTIME
ARCH_DEST = HY2
[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL
ARCH_DEST = /dm8/data/hy/arch
ARCH_FILE_SIZE = 128
ARCH_SPACE_LIMIT = 0

配置dmwatcher.ini
修改dmwatcher.ini配置守护进程,配置为全局守护类型,使用自动切换模式。

[GRP1]
DW_TYPE = GLOBAL                                         #全局守护类型
DW_MODE = AUTO                                           #自动切换模式  生产建议设置成手动
DW_ERROR_TIME = 10                                       #远程守护进程故障认定时间
INST_RECOVER_TIME = 60                                   #主库守护进程启动恢复的间隔时间
INST_ERROR_TIME = 10                                     #本地实例故障认定时间
INST_OGUID = 555555                                      #守护系统唯一OGUID值
INST_INI = /dm8/data/hy/dm.ini                           #dm.ini配置文件路径
INST_AUTO_RESTART = 1                                    #打开实例的自动启动功能(建议设置成0)
INST_STARTUP_CMD = /dm8/bin/dmserver                     #命令行方式启动
RLOG_SEND_THRESHOLD = 0                                  #指定主库发送日志到备库的时间阀值,默认关闭
RLOG_APPLY_THRESHOLD = 0                                 #指定备库重演日志的时间阀值,默认关闭

[dmdba@dm222 hy]$ vi dmwatcher.ini

DW_TYPE = GLOBAL
DW_MODE = AUTO
DW_ERROR_TIME = 10
INST_RECOVER_TIME = 60

配置监视器(基本要求,安装dm8的软件)
由于主库和实时备库的守护进程配置为自动切换模式,因此这里选择配置确认监视器。和普通监视器相比,确认监视器除了相同的命令支持外,在主库发生故障时,能够自动通知实时备库接管为新的主库,具有自动故障处理的功能。

修改dmmonitor.ini配置确认监视器,其中MON_DW_IP中的IP和PORT和dmmal.ini中的MAL_HOST和MAL_DW_PORT配置项保持一致。

MON_DW_CONFIRM = 1                          #确认监视器模式
MON_LOG_PATH = /dm8/data/log                #监视器日志文件存放路径
MON_LOG_INTERVAL = 60                       #每隔60s定时记录系统信息到日志文件
MON_LOG_FILE_SIZE = 32                      #每个日志文件最大32M
MON_LOG_SPACE_LIMIT = 0                     #不限定日志文件总占用空间

[GRP1]
MON_INST_OGUID = 555555                     #组GRP1的唯一OGUID值
                                            #以下配置为监视器到组GRP1的守护进程的连接信息,以“IP:PORT”的形式配置
                                            #IP对应dmmal.ini中的MAL_HOST,PORT对应dmmal.ini中的MAL_DW_PORT
MON_DW_IP = 10.10.13.222:5238
MON_DW_IP = 10.10.13.223:5238

[dmdba@dm225 data]$ vi dmmonitor.ini
MON_DW_CONFIRM = 1
MON_LOG_PATH = /dm8/data/log
MON_LOG_INTERVAL = 60
MON_LOG_FILE_SIZE = 32
MON_LOG_SPACE_LIMIT = 0

[GRP1]
MON_INST_OGUID = 555555


MON_DW_IP = 10.10.13.222:5238
MON_DW_IP = 10.10.13.223:5238

在实际应用中,如果数据库规模很大,并且对数据的实时性要求不是很严格,则可以配置多个异步备库用于分担统计报表等任务。

这里以实时主备环境为例,仍然采用7.2 配置实时主备小节的配置环境,对异步备库的搭建步骤做举例说明,读写分离集群和MPP主备的异步备库搭建步骤是相同的,只需要根据实际情况调整配置项的具体值即可。

这里以一个异步备库为例,配置在主库HY1上,异步备库实例名为HY3。如果需要配置多个异步备库,对应的源实例配置可以参考主库HY1的配置步骤,异步备库自身的配置可以参考HY3的配置步骤。

源实例之间不能有相同的异步归档配置,避免同时向异步备库发送归档,导致异步备库数据乱掉的情况发生。

如果源实例自身出现故障,在故障恢复之前,都不会再发送归档到异步备库,所以如果有多个异步备库,可以考虑将异步备库分别配置到不同的源实例上。

环境说明
这里采用实时主备环境,增加一台机器用来部署异步备库,其他环境不变。

新增的机器事先安装了DM,安装路径为’/dm8’,执行程序保存在’/dm8/bin’目录中,数据存放路径为’/dm8/data’。

新增的异步备库实例名为“HY3”,按照“组名_守护环境_序号”的建议方式命名,注意总长度不能超过16。

机器名    IP地址             初始状态         操作系统              备注

数据准备
按照数据准备中的方法准备异步备库的数据。
如果实时主备守护环境已经处于运行状态,需要先正常退出主备库实例和守护进程。

先正常停止实时主备环境中的主库和备库
停止主库

[root@dm222 ~]# service DmWatcherServicehy1 stop
Redirecting to /bin/systemctl stop DmWatcherServicehy1.service
[root@dm222 ~]# ps -ef | grep dm.ini

配置监视器
在实时主备配置监视器的配置基础上,需要增加到异步备库守护进程的“IP:PORT”信息,否则监视器无法收到异步备库消息,其他配置项不需要改动。

修改dmmonitor.ini配置确认监视器,增加到HY3守护进程的MON_DW_IP配置项,需要找到dmmal.ini中实例HY3的配置项信息,MON_DW_IP中的IP信息和dmmal.ini配置项中的MAL_HOST一致,PORT信息和dmmal.ini配置项中的MAL_DW_PORT配置项保持一致。

MON_DW_CONFIRM = 1                  #确认监视器模式

启动守护进程
启动异步备库的守护进程:

[root@dm224 ~]# /dm8/script/root/dm_service_installer.sh -watcher_ini /dm8/data/hy/dmwatcher.ini -p hy3 -t dmwatcher
Created symlink from /etc/systemd/system/multi-user.target.wants/DmWatcherServicehy3.service to /usr/lib/systemd/system/DmWatcherServicehy3.service.
Finished to create the service (DmWatcherServicehy3)
[root@dm224 ~]# service DmWatcherServicehy3 start
Redirecting to /bin/systemctl start DmWatcherServicehy3.service

守护进程启动后,进入Startup状态,此时实例处于Mount状态,异步备库的守护进程会将本地实例自动Open,并切换守护进程自身为Open状态。

DM8配置MPP主备

配置MPP主备
为了提高MPP系统可靠性,克服由于单节点故障导致整个系统不能继续正常工作,DM在普通的MPP系统基础上,引入主备守护机制,将MPP节点作为主库节点,增加备库作为备份节点,必要时可切换为主库代替故障节点工作,提高系统的可靠性和可用性。

环境说明
本例配置2个MPP节点数,每个节点作为主库,与其备库组成一个守护组,因此需要配置两个守护组,取名分别为GRP1、GRP2,主库名为mpp01/mpp02,对应的备库实例名分别为mpp11/mpp12。

准备5台机器dm8mppdw1,dm8mppdw2,dm8mppdw3,dm8mppdw4和dm8mppdw5,dm8mppdw1和dm8mppdw2为主库,dm8mppdw3和dm8mppdw4和备库,dm8mppdw5部署监视器。

机器事先都安装了DM,安装路径为’/dm8’,执行程序保存在’/dm8/bin’目录中,数据存放路径为’/dm/data/mpp’。

配置dmarch.ini
修改dmarch.ini,配置本地归档和即时归档。
除了本地归档外,其他归档配置项中的ARCH_DEST表示实例是Primary模式时,需要同步归档数据的目标实例名。当前实例mpp01是主库,需要向即时备库mpp11同步数据,因此即时归档的ARCH_DEST配置为mpp11。

[ARCHIVE_REALTIME1]
ARCH_TYPE = REALTIME               #即时归档类型
ARCH_DEST = MPP11                  #即时归档目标实例名

[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL                  #本地归档类型
ARCH_DEST = /dm8/arch              #本地归档文件存放路径
ARCH_FILE_SIZE = 128               #单位Mb,本地单个归档文件最大值
ARCH_SPACE_LIMIT = 0               #单位Mb,0表示无限制,范围1024~4294967294M


[dmdba@dm8mppdw1 mpp01]$ vi dmarch.ini
[ARCHIVE_REALTIME1]
ARCH_TYPE = REALTIME
ARCH_DEST = MPP11

[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL
ARCH_DEST = /dm8/arch
ARCH_FILE_SIZE = 128
ARCH_SPACE_LIMIT = 0

配置dmmpp.ctl
mmpp.ctl是二进制文件,由dmmpp.ini文本通过dmctlcvt工具转换而来,dmmpp.ini配置项如下表:

[SERVICE_NAME1]
MPP_SEQ_NO = 0
MPP_INST_NAME = MPP01
[SERVICE_NAME2]
MPP_SEQ_NO = 1
MPP_INST_NAME = MPP02

[dmdba@dm8mppdw1 mpp01]$ vi dmmpp.ini
[SERVICE_NAME1]
MPP_SEQ_NO = 0
MPP_INST_NAME = MPP01
[SERVICE_NAME2]
MPP_SEQ_NO = 1
MPP_INST_NAME = MPP02

使用DM提供的工具dmctlcvt将dmmpp.ini转换成dmmpp.ctl,dmctlcvt工具在DM安装目录的“bin”子目录中。转换生成的dmmpp.ctl需要放在与dm.ini同一个目录。假设DM的安装路径为c盘根目录,下面的命令将dmmpp.ini转换为dmmpp.ctl,命令中的
“TYPE=2”参数表示将文本文件转换成控制文件,也可以使用“TYPE=1”参数进行逆向转换。

[dmdba@dm8mppdw1 mpp01]$ dmctlcvt type=2 src=/dm8/data/mpp01/dmmpp.ini dest=/dm8/data/mpp01/dmmpp.ctl
DMCTLCVT V8
convert txt to ctl success!

配置dmwatcher.ini
修改dmwatcher.ini配置守护进程,配置为全局守护类型,使用自动切换模式。

INST_ERROR_TIME = 10                                     #本地实例故障认定时间

mpp02同步数据,因此即时归档的ARCH_DEST配置为mpp02

MPP 验证
在MPP主节点1(mpp01)创建测试表:

[dmdba@dm8mppdw1 ~]$ disql SYSDBA/SYSDBA

Server[LOCALHOST:5236]:mode is primary, state is open
login used time : 3.571(ms)
disql V8
SQL> create table test as select * from sysobjects;
executed successfully
used time: 209.673(ms). Execute id is 900.

到MPP主节点2(mpp02)查询:MPP运行正常:

[dmdba@dm8mppdw2 mpp02]$ disql SYSDBA/SYSDBA

Server[LOCALHOST:5236]:mode is primary, state is open
login used time : 3.175(ms)
disql V8
SQL> select count(*) from test;

LINEID     COUNT(*)
