Who Should Attend

Those who will administer WebSphere MQ for z/OS. Administration of WebSphere MQ on the distributed platforms (Windows, UNIX, Linux, OS/400, AIX, Solaris, etc) is covered in the course WebSphere MQ System Administration for Linux, UNIX & Windows.

Prerequisites

Attendees must have a working knowledge of TSO/ISPF and a conceptual-level knowledge of the z/OS computing environment.
