We are considering upgrading our current system from Oracle 9i to 11g. The current operating system is SUSE Enterprise 9.

The 11g requirements say an update to SUSE Enterprise 10 is required to support the Oracle 11g installation.

My question is: Will I need to recompile my existing application programs which use pro C precompiler to create code that accesses the Oracle database when I upgrade the operating system and database?

If your application was compiled with 9i Pro*C you don't need to relink but you may need to relink the exe (unless you also install an 9i Oracle client).
However it is better to recompile the entire program above all if you switch from 32-bit to 64-bit OS.

Michel
