Queued Connections

This number shows the current number of requests for connections that are waiting to receive a connection from the JDBC pool. Connection requests are queued if the current number of leased connections has reached the maximum connections.

Tuning – If this number is consistently greater than zero, consider increasing the JDBC resource's maximum connections. To change the maximum connections for a JDBC resource through the Admin Console, edit the Maximum Connections field on the Edit JDBC Resource page. To change the JDBC resource's maximum connections through the command-line-interface, use wadm set-jdbc-resource-prop and change the max-connections property.
