DB upgrade Bit conversion Issue from 10.2.0.3 to 10.2.0.5
---------------------------------------------------------------------

We are upgrading the database from 10.2.0.3 to 10.2.0.5 ,we have applied the patch 8202632 on oracle home and it was successful.

have opened the database in upgrade mode and running catupgrade script,while running catupgrade script getting the below error.

Solution:
---------
The issue here is 10.2.0.3 database is 32bit and we are trying to upgrade the database to 10.2.0.5 with 64bit version.

we thought catupgrd.sql will also upgrade the database and convert the bit version - (catupgrd.sql calls utlip.sql) ,

But Converting 32-bit databases to 64-bit databases is not automatic for the 10.2.0.5 upgrade.

So to fix this issue, Performed below
------------------------------------
1. Change catupgrd.sql script to always execute utlip.sql
cd $ORACLE_HOME/rdbms/admin
vi catupgrd.sql change:
==> @@&utlip_file
to:==> @@utlip.sql

2. Rerun upgrade with echo on
SQL> spool /tmp/upgrade.logSQL> set echo onSQL> @?/rdbms/admin/catupgrd.sql
