Session manager for VM and VSE & VM/VSAM

[Horlick, Michael]

Greetings,   Cross posted to VSE-L and VMESA-L.   We use CA-TPX as our session manager under VM. This uses VSAM. We also have VM & CSI VSE TCP/IP.  Right now most terminal connections come through VM/VTAM through TPX to our CICS/TS VSE applications via a virtual CTCA controlled by VSE/VTAM.   We should be getting a Z800 computer in the near future and plan to upgrade our existing zVM 3.1 & VSE/ESA 2.6.1 system.   What am I think is the possibility of eliminating (or reducing) VTAM (both VM & VSE) and from what I am reading in previous posts CA-TPX since it depends VM/VSAM. Am I correct in assuming CA-TPX will not work when going to zVM 5 environment ?   I am also vaguely aware of the BSI ITAM option to allow you to connect to CICS/TS application without VTAM.   Ideas / suggestions?   Thanks   MIke
