Thanks Niall ? I think you touched on something that I have not looked at yet:
"or in java or forms"
Is there a way to look/check in these places other than doing a "find in files"
search on the EBS APPS Server?

Subject: Re: Table use investigation
In EBS the XX prefix is specifically recommended for customisation and so I'd
bet actual money you have a customisation that does this, either in an XX
Schema or in java or forms. True story (assuming you believe something you read
on the internet that retells a personal experience of someone other than the
author) - prior to 11i Imperial College London had a set of custom code they'd
carefully separated out from apps code. Being diligent they'd used a 3 char
schema name nit in use. Being sensible they'd taken ownership of it and since
it extended their functionality the ICX schema was born I understand that the
upgrade was hell and the guidelines were born.

I have assumed responsibility for a 5 year old running EBS 12 database and
came across a mysterious table that has grown to 186m rows. It is created
via trigger on a standard EBS (Advanced Pricing) table named:
QP.QP_PREQ_LINE_ATTRS_TMP_T. This trigger basically archives the data from
this GTT from Advanced Pricing in EBS.
I have searched dba_objects with:
select * from dba_source where upper(text) like
'%XXQP_PREQ_LINE_ATTRS_TMP_T%'
- but the only object returned is the trigger that writes to it.
I have also searched SQL with:
SELECT * FROM DBA_HIST_ACTIVE_SESS_HISTORY WHERE SQL_ID IN (
select SQL_ID from DBA_HIST_SQL_PLAN
where OBJECT_NAME = 'XXQP_PREQ_LINE_ATTRS_TMP_T')
- nothing returned their either.
Since we use Discoverer, I searched:
select * from EUL_US.EUL5_OBJS
where SOBJ_EXT_TABLE like '%XQP_PREQ_LINE_ATTRS_TMP_T%'
And with:
SELECT Obj.Obj_Name,
Obj.Obj_Ba_Id,
Seg.Seg_Chunk1,
Seg.Seg_Chunk2,
Seg.Seg_Chunk3,
Seg.Seg_Chunk4
FROM Eul_Us.Eul5_Segments Seg, Eul_Us.Eul5_Objs Obj
WHERE Seg.Seg_Seg_Type = 5
AND Seg.Seg_Cuo_Id = Obj.Obj_Id
AND ( upper(Seg.Seg_Chunk1) LIKE '%XXQP_PREQ_LINE_ATTRS_TMP_T%'
OR upper(Seg.Seg_Chunk2) LIKE '%XXQP_PREQ_LINE_ATTRS_TMP_T%'
OR upper(Seg.Seg_Chunk3) LIKE '%XXQP_PREQ_LINE_ATTRS_TMP_T%'
OR upper(Seg.Seg_Chunk4) LIKE '%XXQP_PREQ_LINE_ATTRS_TMP_T%')
ORDER BY Obj.Obj_Id, Seg.Seg_Sequence;
- both return nothing also.
Another observation: Since there are no indexes on this table, I wonder
what really could be using this table as any reads would require a very
long full table scan (FTS) of 186m rows?
Is there any other place I can look to see? I was thinking that we have a
customization to Advanced Pricing and I was going to check code on the EBS
Application Server next but based on the above, I'm doubtful that it would
return anything. I also did "Find in Files" on every file on our IT share
- nothing turned up there also.
There are two other tables that mimic the same characteristics - I found
them being used in a Custom Folder in Discoverer and have a plan ready for
these.
Thanks,
Anthony
