title: Weblogic ResourceLimitException with JNDI data-source
body: <p>I have deployed a third party web-application onto my Weblogic server and this application connects to Oracle Database using JNDI data-source that I have defined in my weblogic server. Now while I use the web-application, I don't see any issues, and after accessing the application for a while it throws an exception as below- </p>
  
  <pre><code>weblogic.common.resourcepool.ResourceLimitException: No resources currently available in pool test_db to allocate to applications, please increase the size of the pool and retry.. caused by: weblogic.jdbc.extensions.PoolLimitSQLException: 
  </code></pre>
  
  <p>How can I debug this issue using my weblogic server? Is there any log file that contains details on why all the connections are still used? </p>
