Tuning Generic Data Sources

Hi

I'm creating a best practices guidance on tuning within Oracle WebLogic Server 12c.

I'm currently looking at tuning data sources.

I'm curious around using the 'Test Reserved Connections' for the generic data source types. I understand the trade-off between overhead and safety. Lets assume the option is selected. To avoid overkill by executing the fully-fledged SQL query each time for each connection, I am also considering using the 'Test Connection On Reserve' feature in conjunction with 'Test Reserved Connections'. The 'Test Connection On Reserve' feature allows WebLogic to skip the fully-fledged SQL query for a previously used connection, the default being 10 secs. After 10 secs the test would kick in. (See ML: 880171.1)

Howdy, Stranger!
