Re: Oracle Apps Upgrade from 11.5.10.2 to R12.1.1

Hi Bala,
I don't really have any solutions for your situation, but a few comments:

First: If you skip a documented step for the R12 upgrade without the
direction of Oracle Support, you are leaving your system in an
unsupportable state.  Do *not* do this.

A quick search on Metalink turns up several notes regarding performance of
the appdstln.sql script, both for 12.0 upgrades and 12.1 upgrades.  One of
the notes (1088273.1) states explicitly, "NOTE: These patches and processes
must be applied PRIOR to starting your upgrade. If you experience the
performance issues after you have already begun, you will probably have to
start fresh."

Finally, 2 weeks is a long time to wait for assistance from Oracle on what
I assume is a time-critical project.  I strongly recommend engaging with
the Duty Manager to escalate this issue within Oracle Support.  The fact
that I was able to find references on on this topic with a very
lightweight Metalink
search suggests that you should be able to get help from resources
within Oracle to address your problem.  If your current support analyst
cannot help you, it is part of the Duty Manager's job to help find someone
who can.

Good luck!

Regards,

John Piwowar
