CONNX support for Oracle OCI Session Pooling

Our systems run Oracle 19 Rac environment.

Connections establish through services using failover parameters (Tac configuration).

This is the configuration of the service:

srvctl add service -db thila -service thila_tac -preferred thila_1,thila_2 -failovertype AUTO -failover_restore AUTO

Oracle documentation instructs using this option for TAC support:

  • OCI Session Pool 12c Release 2

After consulting SAG support, we understand that Connx uses OCI but it doesn't use OCI session pool.

Since we are using heavily Connx for replicating Adabas database to Oracle, It will improve our system availability if Connx supports OCI session pool.
