Home -> Community -> Mailing Lists -> Oracle-L -> RE: Enqueue Waits in Oracle Financials
Here is the output from the query:
Sid/Ser# DB/OSUser StartTime Mins Rbs Name Blks Status
---------- --------------- ------------------ ---- ---------- ----- ------------ 14/106 APPS/applmgr 12/06/02 01:29:32 518 RBS2 1 ACTIVE 33/537 APPS/applmgr 12/06/02 07:59:42 128 RBS11 1 ACTIVE 160/285 APPS/applmgr 12/06/02 09:29:01 39 RBS10 1 ACTIVE 165/234 APPS/applmgr 12/06/02 09:58:54 9 RBS14 1 ACTIVE 71/240 APPS/applmgr 12/06/02 10:07:24 0 RBS24 1 ACTIVE 45/2 APPS/applmgr 12/06/02 10:07:37 0 RBS8 1 ACTIVE 83/280 APPS/applmgr 12/06/02 10:07:42 0 RBS27 1 ACTIVE
7 rows selected.
The offending SID today is 16, which I don't see in the output from the above query.
SQL> run
1 select sid,
2 event, 3 total_waits tws, 4 total_timeouts tt, 5 time_waited tw, 6 average_wait avgw
Sess Total Total Time (ms) Avg (ms) ID Wait Event Waits Timouts Waited Wait ----- ------------------------------------- -------- ------- --------- -------- 16 enqueue 5594 5589 572543 102 10 enqueue 1 0 13 13 45 enqueue 1 0 12 12
I map this SID (16) back to the Internal Manager. By the way, SID 14 (with the highest "Mins" in your query) is the Service Manager. We scaled back our Alert manager to 1 process because we replaced some of our Alerts with triggers. The Alerts where just too much of a performance problem on our system (they were over 1/2 of our concurrent requests). Do we have any "new fangled" modules? Yes. Service and Contracts. Are we using OAM? It is installed, but we're not using it. I stumbled into it already and brought up some pretty graphs.
Thanks,
Jay

Jay,
Does this come from the alert manager? Do you have any of those new-fangled 11i modules (or should I call the 'mangled'!!). You could use the script below (adapted from Govind who posted this a few days back)
set pages 100
column sid_serial format a10 heading "Sid/Ser#"
column username format a15 heading "DB/OSUser"
column start_time format a18 heading "StartTime"
column mins_pending format 999 heading "Mins"
column used_ublk format 9999 heading "Blks"
column name format a10 heading "Rbs Name"
column status format a12 heading "Status"
select sid || '/' || serial# sid_serial, username || '/' || osuser username,
substr(t.start_time,1,18) start_time,
round( ( sysdate - TO_DATE( start_time, 'MM/DD/YY HH24:MI:SS')
) *24*60 ,0 ) mins_pending,
r.name, t.used_ublk ,
decode(t.space, 'YES', 'SPACE TX',
decode(t.recursive, 'YES', 'RECURSIVE TX',
decode(t.noundo, 'YES', 'NO UNDO TX', t.status))) status
from v$transaction t, v$rollname r, v$session s
where t.xidusn = r.usn
If the OS user turns out to be 'applmgr' for any waiting TXN then pursue this from the CM side. Otherwise, you can look at the Forms users. In any case, are you using OAM (Oracle Applications Manager)?
