WebSphere MQ and UNIX System V IPC resources

 

This information applies to WebSphere MQ running on UNIX systems only.

WebSphere MQ uses System V interprocess communication (IPC) resources (semaphores and shared memory segments) to store and pass data between system components. These resources are used by queue manager processes and applications that connect to the queue manager. WebSphere MQ clients do not use IPC resources, except for WebSphere MQ trace control. Use the UNIX command ipcs -a to get full information on the number and size of the IPC resources currently in use on the machine.
