5.4. Maximum pool size

The max-pool-size parameter data source parameter defines the maximum size of the connection pool. It's more important that the min-pool-size parameter because it limits the number of active connections to the data source and so the concurrent activity on the data source. If this value is set too low it's likely that the platform's hardware resources will be underutilized.


Setting the max-pool-size too low is a common configuration error.
