OGG replicat进程延迟分析步骤

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

[Oracle@hosta ~]$ 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

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

[oracle@hosta ~]$ 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

三、查询sql信息，分析执行计划

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。
