Answer 1

When you speak of the concurrent request which is making the request to get stuck you can use the below suggestions to find this :
1. Locate which request is running for a long time ?
2.Check the sid of request and see if its creating lock in the database :
SELECT a.request_id, d.sid, d.serial# ,d.osuser,d.process , c.SPID
FROM apps.fnd_concurrent_requests a,
apps.fnd_concurrent_processes b,
v$process c,
v$session d
WHERE a.controlling_manager = b.concurrent_process_id
AND c.pid = b.oracle_process_id
AND b.session_id=d.audsid
AND a.request_id = &Request_ID
AND a.phase_code = 'R';Then see if this sid is causing locks in the database :
select * from v$lock where block<>0;Also :
1. to see the managers :
login to application -> sysadministrator -> concurrent:Manager -> administer
see the acual target , they should be equal. and the Internal Manager should be up.
Also check the spaces in the $APPL_TOP and the database Archive. that also slows down the application.
