编译存储过程时被卡死的处理方法

同事修改存储过程trans_kc21时过程无法被编译被卡死
查V$DB_OBJECT_CACHE

SQL> SELECT * FROM V$DB_OBJECT_CACHE WHERE name=upper('trans_kc21') AND LOCKS!='0';

发现locks=1

按对象查出sid的值
v$access显示目前库缓存对象被锁定的信息,这个被强加的锁用来确保库缓存对象
在sql执行请求它时不会被老化

SQL> select SID from V$ACCESS WHERE object=upper('trans_kc21');

       SID
----------
      6566

查看session 状态

SQL> select a.SID,a.SERIAL#,b.SPID from v$session a,v$process b where a.SID=6566 and a.PADDR=b.ADDR;

       SID    SERIAL# SPID
---------- ---------- ------------------------
      6566         27 23462626

kill这个会话

SQL>alter system kill session '6566,27';

如果这个会话已经是被kill的

SQL> select a.SID,a.SERIAL#,b.SPID,a.STATUS from v$session a,v$process b where a.SID=6566 and a.PADDR=b.ADDR;

       SID    SERIAL# SPID                     STATUS
---------- ---------- ------------------------ --------
      6566         27 23462626                 KILLED

就要在操作系统层来kill

[/@zzld03]#kill -9 23462626
