Jared,

Those tables are transit type of tables and depending on your volume of data, there are lot of deletes and inserts all the time resuling index fragmentation(holes due to deletes) and space usage.

The rebuilding not only release the space but also reduces the index fragmentation. If you don't have table truncation option for such tables then it is much better to rebuid indexes on such tables at regular interval to release space and for better performance.

As regard quantification, you many release sufficient amount of space if your usage is higher. Here it was 7.3.4 database so no LMT involved.

Regards
Rafiq

Please explain why these indexes must be built.

What benefits do you see from it?

Are they quantifiable?

Jared

John What about gl_interface table indexes? I think indexes on all *interface( tables must be rebuild on a regular interval...I was building indexes on gl_interfaces and fnd_request* tables on monthly basis.

Hemant,

This applies on 11i only. I would rebuild all indexes supporting the
WF_ITEM_ACTIVITY_STATUSES and WF_ATTRIBUTE_VALUES tables. I have been
working on some AOL table(space) problems in the background and noticed
that
in 11i by default, we are not be purging _all_ the WF data that we should
be
purging. I believe the current Purge routine purges activity rows whose
persistence has expired and are marked 'TEMPORARY' and ignores those that
are COMPLETE (see below). My contention is that it should be deleting old
rows that are COMPLETEd... (Fyi, this is 12+ million rows...) Notes
141853.1, 144806.1, 132254.1, 148705.1, 148678.1 may help.

You could check this using the following SQLs

select activity_status, count(*)
from applsys.wf_item_activity_statuses
group by activity_status;

select item_type,activity_status,count(*)
from
applsys.wf_item_activity_statuses where activity_status='COMPLETE'
group by item_type,activity_status;

Once the 'correct' purge is complete, the 'holey' indexes will need to be
rebuilt and the WF_ tables copied/truncated/recopied to shrink the HWM to
reasonable levels.

Let me know what your install shows up.

John,

I rebuild the FND_CONCURRENT_REQUESTS indexes every four months [and the
table itself, occassionally].
This Saturday I will also be rebuilding some ALR indexes.
Which WorkFlow Indexes do you rebuild ?
