Linux Use ODBC Connect Oracle

因为工作需要,需要使用ODBC访问Oracle,下面是ODBC访问Oracle的具体配置
1.下载unixODBC和Oracle简易客户端软件包
1.1下载地址:

http://www.unixodbc.org/

1.1.1下载文件:

unixODBC-2.3.0.tar.gz

2 Oracle ODBC Driver
2.1下载地址:

http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

2.1.1下载文件:

instantclient-sqlplus-linux.x64-12.2.0.1.0.zip
instantclient-basic-linux.x64-12.2.0.1.0.zip
instantclient-sdk-linux.x64-12.2.0.1.0.zip
instantclient-jdbc-linux.x64-12.2.0.1.0.zip
instantclient-odbc-linux.x64-12.2.0.1.0-2.zip
instantclient-basiclite-linux.x64-12.2.0.1.0.zip
instantclient-tools-linux.x64-12.2.0.1.0.zip

将这些软件包上传到/soft目录

3.安装unixODBC(root用户)

#cd /soft
#tar xvf unixODBC-2.3.0.tar.gz
#cd /soft/unixODBC-2.3.0
#./configure
#make
#make install

(默认是被安装到/usr/local)

4.安装Oracle ODBC(root用户)

#cd /soft/
#unzip instantclient-sqlplus-linux.x64-12.2.0.1.0.zip
#unzip instantclient-basic-linux.x64-12.2.0.1.0.zip
#unzip instantclient-sdk-linux.x64-12.2.0.1.0.zip
#unzip instantclient-jdbc-linux.x64-12.2.0.1.0.zip
#unzip instantclient-odbc-linux.x64-12.2.0.1.0-2.zip
#unzip instantclient-basiclite-linux.x64-12.2.0.1.0.zip
#unzip instantclient-tools-linux.x64-12.2.0.1.0.zip
[root@dmks instantclient_12_2]# ./odbc_update_ini.sh /usr/local
 *** ODBCINI environment variable not set,defaulting it to HOME directory!

更新操作完成后,会在/usr/local/etc/odbcinst.ini增加Oracle12C的驱动描述信息。

[root@dmks etc]# cat odbcinst.ini
[DM7 ODBC DRIVER]
Description = ODBC DRIVER FOR DM7
Driver = /dm_home/dmdbms/bin/libdodbc.so


[Oracle 12c ODBC driver]
Description     = Oracle ODBC driver for Oracle 12c
Driver          = /soft/instantclient_12_2/libsqora.so.12.1
Setup           =
FileUsage       =
CPTimeout       =
CPReuse         =

并且会在HOME目录下也就是/root,生成.odbc.ini文件,修改.odbc.ini文件

[root@dmks ~]# cat .odbc.ini
[OracleODBC-12c]
Application Attributes = T
Attributes = W
BatchAutocommitMode = IfAllSuccessful
BindAsFLOAT = F
CloseCursor = F
DisableDPM = F
DisableMTS = T
Driver = Oracle 12c ODBC driver
DSN = OracleODBC-12c
EXECSchemaOpt =
EXECSyntax = T
Failover = T
FailoverDelay = 10
FailoverRetryCount = 10
FetchBufferSize = 64000
ForceWCHAR = F
Lobs = T
Longs = T
MaxLargeData = 0
MetadataIdDefault = F
QueryTimeout = T
ResultSets = T
ServerName = shardcat 与tnsnames.ora文件中的服务器一致
SQLGetData extensions = F
Translation DLL =
Translation Option = 0
DisableRULEHint = T
UserID =
StatementCache=F
CacheBufferSize=20
UseOCIDescribeAny=F
SQLTranslateErrors=F
MaxTokenSize=8192
AggregateSQLType=FLOAT
5.测试ODBC连接Oracle
[root@dmks ~]# isql  OracleODBC-12c system xxzx7817600 -v
