JMS Pooled Connections
Overview
A pooled JMS connection is a session pool used by EJBs and servlets that use a resource-ref element in their EJB or servlet deployment descriptor to define their JMS connection factories (also known as a wrapped connection factory). This tab enables you to monitor JMS connection and session objects, as well some message producer objects that are automatically created when declaring a wrapped JMS connection factory in your EJB or servlet.
For more information on using JMS wrappers with EJBs and servlets to create pooled JMS connection objects, see "Using JMS With EJBs and Servlets" in Programming WebLogic JMS.
Num Leaked — The number of JMS sessions that were removed from the session pool, but which were not returned.
Num Failures To Refresh — The number of failed attempts to create a JMS session in the session pool.
Creation Delay Time — The average amount of time that it takes to create each JMS session in the session pool.
Num Waiters — The number of threads waiting to retrieve a JMS session from the session pool.
Highest Num Waiters — The highest number of threads waiting to retrieve a JMS session in this instance of the session pool since it was instantiated.
Highest Wait Seconds — The highest number of seconds that an application waited to retrieve a JMS session in this instance of the session pool since it was instantiated.
Num Reserved — The number of JMS sessions that are currently in use.
Highest Num Reserved — The highest number of concurrent JMS sessions reserved for this instance of the session pool since it was instantiated.
Num Available — The number of available JMS sessions in the session pool that are not currently in use.
Highest Num Available — The highest number of available JMS sessions in this instance of the session pool since it was instantiated.
Num Unavailable — The number of JMS sessions in the session pool that are not currently usable for some reason.
Highest Num Unavailable — The highest number of unusable JMS sessions in this instance of the session pool since it was instantiated.
Total Num Allocated — The total number of JMS sessions allocated by this session pool in this instance of the session pool since it was instantiated.
Total Num Destroyed — The total number of JMS sessions that were created and then destroyed in this instance of the session pool since it was instantiated.
Max Capacity — The maximum number of JMS sessions that can be allocated using the session pool.
Curr Capacity — The current capacity of the sesssion pool, which is always less than or equal to the maximum capacity of JMS sessions.
Average Reserved — The average number of JMS sessions that have been in use in this instance of the session pool since it was instantiated. This generally happens when an EJB or servlet is deployed that requires the session pool.
Num Connection Objects — The number of JMS connections that back this session pool. This value may be greater than one if different sessions were created using different combinations of a username and password to contact the JMS server.
