Oracle数据库编译存储过程假死问题

Oracle数据库教程编译存储过程假死问题


这种情况下如果强行终止存储过程编译,再次Recompile存储过程会发现还是挂死的,这个主要是由于强行终止后会话为INACTIVE状态,但是该会话却没有被真正的释放。使用如下语句查询出挂起的会话:

SELECT V.OSUSER, V.PROCESS, V.PROGRAM, v.MACHINE, V.TERMINAL, V.MODULE, V.USERNAME, V.STATUS, V.SID, V.SERIAL#, 'alter system kill session '''||V.sid||','|| V.SERIAL#||''';' as KILL_SESSION, V.PADDR

FROM V$SESSION V

WHERE V.USERNAME LIKE '%USERNAME%'

AND V.PROGRAM like 'PlSqlDev%'

AND V.OSUSER LIKE '%%'

AND V.STATUS='INACTIVE';

将结果中KILL_SESSION一列复制,在sqlplus下执行,杀掉这些未释放的会话,再重新登录到plsql下recompile刚才的存储过程A就OK了


处理方法一 :
            1.SELECT saddr,sid,serial#,paddr,username,status FROM v$session
            WHERE username IS NOT NULL
            example:saddr,sid,serial#,paddr,username,status FROM v$session WHERE
            username = 'XNJW0419' ;
            SADDR SID SERIAL# PADDR USERNAME STATUS
            -------- ---------- ---------- --------
            ------------------------------ --------
            542E0E6C 11 314 542B70E8 EYGLE INACTIVE 542E5044 18 662 542B6D38 SYS
            ACTIVE
            2.ALTER SYSTEM KILL SESSION 'sid, serial#';
            example:ALTER SYSTEM KILL SESSION '11,314';(注:在sqlplus中执行 )
            结果: 提示标记要删去的会话 无法释放会话,未成功解锁
            ====================================================================================================
            处理方法二 :
            a、 找到你要杀掉的那个SESSION, 并记下paddr
            SELECT sid, username, paddr, status FROM v$session WHERE username =
            '用户名' ;
            example:SELECT sid, username, paddr, status FROM v$session WHERE
            username = 'XNJW0419' ;
            SID USERNAMEPADDRSTATUS
            ---------- ------------------------------ -------- --------
            10 XNJW04192B5E2E2C KILLED
            b、 找到这个SESSION所对应的spid
            SELECT * FROM v$process WHERE addr = '上面查寻的paddr';
            example:SELECT ADDR,PID,SPID,USERNAME,SERIAL#,TERMINAL FROM
            v$process WHERE addr = '2B5E2E2C';
            ADDRPID SPIDUSERNAMESERIAL# TERMINAL
            -------- ---------- ------------ --------------- ----------
            ----------------
            2B5E2E2C44 1204SYSTEM-99 JWC
            c、 杀掉spid所标识的那个进程
            D:>orakill sid  spid (注:cmd命令窗口中执行 只有oracle服务器端才有orakill命令)
            example: D:>orakill oemrep 1204
            提示:KILL OF THREAD id 1204 IN INSTANCE oemrep successfully signalled.
            结果:成功删除该SESSION,表也解锁
