The absolutely easiest way is to upgrade your current hardware to a faster machine. This only requires oodles and gobs of money, but no other action on your part. Easy, no? <GRIN> Historically, the reason that a CICS region can only use a single region is that all the application code has been dispatched on a single z/OS TCB, called the QR TCB. Now, if you can rewrite a fair number of your applications to be "ThreadSafe" and you are on the latest release of CICS, then you can set up a transaction to run in what is called an OTE environment. In this, the transactions are eligable to run on different TCBs (L8 & L9, I think they are called). Since z/OS can then dispatch these different TCBs on separate CPUs, you can run more transactions by using multiple CPUs simultaneously. Of course, since this requires rewriting, or at least validating, the current code to be ThreadSafe, this is not really a good option. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
