Tommy,' You say you are VSAM. There is a sub-task for some VSAM functions which is an option within a CICS address space. I do not think it takes a lot away from the main task, but make sure you are using this option. You could set up a TOR and route to multiple AORs and for VSAM read only files, these could be shared between AORs. For update files create a FOR and ship the requests from the AOR to the AOR. You could ship all VSAM requests to the FOR if you want. This will add to the overall CPU but will split the load across several tasks. It should not require application code changes. You need to decide how to split the load between the AORs and implement in the TOR the appropriate routing. You can use CICSPLEX SM to control the routing or create your own routing exit. I thought most users use the TOR/AOR structure now. to avoid your problem. I would also look at data tables to try to reduce the CPU load for VSAM accesses. Or you could go out and buy a big engine z10. Terry Draper zSeries Performance Consultant w...@btopenworld.com mobile: +966 556730876

We have not implement OTE yet that means we only has QR TCB. As you know, we have to re-write many user program either switch to cicsplex with RLS or DB2 access.
