Hi

In WAS there is a connection pool property where one can specify a test SQL that is executed by the pool manager to test a connection before it is returned from the pool ( dead connection detection ). In case the SQL fails then the pool manager creates a fresh connection and returns that..

Is a similar facility available foe IIB for ODBC & JDFC ? If so, how do I enable it ?

Every morning I get an error about dead connections in my esql code , this is because the connections in the pool are dead ( the firewall breaks long running connections ) ., currently we restart the broker every morning , . What is the recommended way to handle this ?

I am not personally aware of such a facility.

Have you modified the Broker "maxConnectionAge" property, I wonder if this could be tuned to ensure the connection is not held open and ild for long enough to be broken by the firewall?
