Hi,

I have an application on mainframe that needs to call via RPC a subprogram that access Oracle.

The problem on it is that depend on the situation, the mainframe application needs to call a different Oracle instance.

Does anyone know how to handle it? Is there a way to change it dynamically or I need to create RPC servers for each one of instances?

Thank you.

Regards,
