Insert query waiting for in-definite time.

Question

Hi all,
I had a serious problem in my system.
My application gets stuck when trying to insert a huge xml message in a table blob. Usually there is no problem, the insert query goes into wait state just around or after the gather stats running on this table ends.
The table is partitioned one and around 150Gb in size.
I have seen in toad the wait event for this insert query is SQL* net more data from client.
This might be something related to RBS usage of this stuck insert query - in toad the RBS usage start time is same as the end time of gather stats.
But i m unable to figure out why the insert is stuck just after the gather stats ends, i have simulated this issue many times. My oracle version is 9.0.8.
Could somebody help to figure out why this is happening...?

Answer 1

My oracle version is 9.0.8.I doubt this is correct.
Post Operating System (OS) name & version for DB server system.
Post results of SELECT * from v$version.
Now CUT the commands & results & PASTE (post) them back here.
ALTER SESSION SET SQL_TRACE=TRUE;
-- invoke the problem SQL here
ALTER SESSION SET SQL_TRACE=FALSE;
now find the trace file within ./udump folder
tkprof <trace_file.trc> trace_results.txt explain=<username>/<password>
post the contents of trace_results.txt back here
when application "gets stuck" run the following SQL from different session
SELECT DECODE(request,0,'Holder: ','Waiter: ')||sid sess,
id1, id2, lmode, request, type
FROM V$LOCK
WHERE (id1, id2, type) IN
(SELECT id1, id2, type FROM V$LOCK WHERE request>0)
ORDER BY id1, request
