OGG rep运行慢的分析步骤

OGG rep运行慢的分析步骤：

第一：按照rep的进程名进行 ps -ef | grep ，获得rep的进程PID

[[email protected] ~]$ ps -ef | grep repfull
oracle   27906 27861  0 18:01 pts/7    S+     0:00              \_ grep repfull
oracle   27603 20773  1 17:03 ?        Ssl    0:51  \_ /u02/ggs/replicat PARAMFILE /u02/ggs/dirprm/repfull.prm REPORTFILE /u02/ggs/dirrpt/REPFULL.rpt PROCESSID REPFULL USESUBDIRS
           

第二：按照rep的进程PID 进行 ps -ef | grep，以获得27603产生的LOCAL=YES的进程

[[email protected] ~]$ ps -ef f | grep 27603  
oracle   27910 27861  0 18:01 pts/7    S+     0:00              \_ grep 27603
oracle   27603 20773  1 17:03 ?        Ssl    0:52  \_ /u02/ggs/replicat PARAMFILE /u02/ggs/dirprm/repfull.prm REPORTFILE /u02/ggs/dirrpt/REPFULL.rpt PROCESSID REPFULL USESUBDIRS
oracle   27607 27603  2 17:03 ?        Ds     1:41      \_ oracleorcl (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))   ---->这一个就是。
[[email protected] ~]$ 
           

sqlplus 里执行如下sql即可：

SELECT sql_text,sql_id FROM v$sqltext a WHERE a.hash_value = (SELECT sql_hash_value FROM v$session b 
WHERE b.SID =( select s.sid from v$session s,v$process p where s.paddr=p.addr and p.spid='27607'))   ---> 替换上27607
ORDER BY piece ASC;
           

select plan_table_output from table(dbms_xplan.display_cursor('6ufrk02y1h6u5'));  --->替换为上一步查询得到的sql_id，查看其执行计划。
