Monitoring connection pools

The Connection Pools panel under the Connection Management heading in the left navigation frame displays information about defined connection pools. A connection pool is not listed until at least one connection is allocated from the pool.

Connection pools are collections of communication links to back-end data sources, such as 3270 applications or databases. When an Integration Object or an application is run on behalf of a client request, it obtains an available connection from a pool, uses it for access to the data source, then returns the connection to the pool. When connection pooling is enabled, the processor usage of establishing a connection is absorbed in its first use. Each reuse of this connection benefits from the prior establishment of the connection and can run faster.
