10gAS (10.1.2.3) patching on the concurrent tier?
We are upgrading from 11.5.10.2 to R12.1.3. Our current 11i architecture is your standard multi-tier environment: one database/concurrent tier and one middle tier. We have preserved that for R12 and therefore installed Batch Processing Services enabled on the database tier and everything else enabled on the middle tier (Root, Web Entry, Web Application and Other Services). The database tier obviously has the database too.
As part of the upgrade process we patched the middle tier forms server. I.e. The 10.1.2 $ORACLE_HOME. The process is in oracle note 437878.1 "Upgrading OracleAS 10g Forms and Reports in Oracle EBS Release 12".
Since there are reports server patches that get applied as part of this document, do I need to follow this document again for the database/concurrent tier too? I.e. The 10.1.2 $ORACLE_HOME on the Batch Processing Services.
