In this tip, he offers you both methods, and explains how you can improve CICS performance by implementing one of these utilities. >> CLICK for the full tip: http://www.search390.com/tip/1,289483,sid10_gci880769,00.html Love this tip?

This was when a CICS address space had only one TCB. The latest versions of CICS have three and four TCBs. The major TCB, when looking at CICS shutdown stats, is the Quasi (QR-TCB). It is my understanding that you can determine how busy the QR-TCB is by dividing the accumulated CPU time by the accumulated time the TCB was dispatched. If this percent busy is at 80% or greater, will there be performance issues? >> CLICK for Robert's expert response: http://search390.techtarget.com/ateQuestionNResponse/0,289625,sid10_cid510020_tax289214,00.html =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= CICS TRANSACTION SERVER FOR Z/OS V2.2 PERFORMANCE | White paper If you're looking to glean some performance advantages of open trusted computer bases (TCB) like reduced TCB switching, peruse this white paper from IBM Hursley.
