This document explains how to release the connections, which are not released in the connection pool, even after BPEL process has ended.

In the log files you might notice some error such as:

Exception: Unable to get a physical connection from the database...there are no connections

We can also observe from the Enterprises Manager (EM) the following result:

For example,Connection Pool Metrics: "BPELPM_CONNECTION_POOL"

Pool Usage

Connections In Use 469

Free Connections 102

Total Connections in Pool 571

Threads Waiting for Connections 0

EM Navigation: login to the Application server control --> click instance name --> 'Administration'-> JDBC Resources --> then click 'go to task' icon --> In the Connection Pools section --> click 'Monitor Performance' of that connection pool, the "Pool Usage"
