Re: Table use investigation

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?

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.

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%'
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.
