Pro*COBOL: PRCP in Oracle Connection Manager don't work as expected. Fix? / Alternatives?

Hi everyone,

we are using Oracle Client 19.4 running against a Oracle 19.8 DB.

We would like to implement connection pooling for our COBOL-Application.

The release notes for Pro*COBOL 18.1 states that support for Oracle Connection Manager (CM) in Traffic Director Mode (TDM) was added to Pro*COBOL. And Part of the Traffic Director Mode is the proxy resident connection pool (PRCP).

We set up a CM that runs in TDM and has a PRCP.

While testing we're noticed that PRCP don't work as expected.

Every time we reconnect our application to the CM (TDM with PRCP) we seem to get the same session as before (same SID) but session cursor cache etc. is reseted. It seems that the dedicated server process get reused but the actual session is initialized. If we close the session the entry in V$SESSION is also gone

Howdy, Stranger!
