IMS coupled with Sysplex technologies can greatly improve IMS's scalability, availability and performance. However, running IMS in a Sysplex environment brings some configurational and operational challenges. CF structures and SQ monitoring, transaction affinity management, long lock detection, buffer overflow protection, and RM structure management are task that IMS administrators have not dealt with before. Learn how to effectively cope with these challenges with IMS Sysplex Manager.
