Appendix G. WebSphere MQ and UNIX System V IPC resources

This information applies to WebSphere MQ running on UNIX(R) 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 resource are used by queue manager processes and applications that connect to the queue manager. WebSphere MQ clients do not use System V IPC resources. Use the UNIX command ipcs to view the number and size of these resources that the system uses.
