Impact of Application DB Upgrade (10.2.0.4 to 11.2.0.4) on 10g Forms, Pro*C, Pro*Cobol 3rd Party App
We are doing our upgrade from 10g to 11 in phases, beginning with the Database only, leaving the Oracle Application Server 10.1.2.2 unchanged (it will still use a 10.2 database on the dedicated Middle-tier + Infra Application server for the Repository). So far, our understanding is that, as long as the repository database is unchanged, there should be no changes needed for the Applications to talk to the 11.2 database on a separate server (please advise if there are contraindications).
Our focus at the moment is planning any necessary modifications to the 3rd party apps we use (written in 10g forms, Pro*C and Pro*Cobol) in order for them to be compatible with the the 11.2 database.
