Oracle ERP Interface堵住--Request Running too long time，查找Request执行的Sql

Request Running too long time

堵住了INV Manager

导致INV Interface Pending 很多笔资料

Review 发现Request 实际执行SQL 为空，Request Idle（SQL 如下，之前weiheng提供，很好用）

通过Cancel Request 后，状况恢复正常

具体Sql：

--------------------------------

-- 由request id 查 os procesee id

select os_process_id from apps.fnd_concurrent_requests where request_id='&Request_id';

--由os process id 查 sid

select s.INST_ID,s.PROCESS,s.SID,p.SPID,s.LAST_CALL_ET,s.MACHINE,s.SERIAL#,s.OSUSER,s.USERNAME,s.PADDR

from gv$session s,gv$process p

where s.PROCESS='&Process' and s.PADDR=p.ADDR;  

--由SID查目前wait event

select s.SID,so.CONSISTENT_GETS,s.LAST_CALL_ET,sw.EVENT,sw.*

from v$session s,v$sess_io so,v$session_wait sw

where s.SID = '&SID'

and s.SID=so.SID and s.SID=sw.SID;

--由SID查目前執行sql

select s.SID "db session",sq.sql_text "SQL_COMMAND"

from gv$process p,gv$session s,v$sqltext sq

where

p.ADDR = s.PADDR(+) and s.sql_address=sq.address(+) and s.sql_hash_value=sq.hash_value(+) and

s.SID = '&SID'

order by sq.PIECE;
