We moved a production z/OS 1.7 system to a z9 BC this weekend. On Monday, we had to put it back on our z/890. Our sand box has been running just fine on the z9 since it was installed about a week ago.
The problem we had was with a PC based application that uses APPC / LU 6.2 through a WinNT server running CICS Transaction Gateway to talk to a CICS/ESA 4.1 region. We still have our test system (same z/OS and CICS levels) running on the z9, and were able to recreate the same symptoms (ACUA abend in CICS region) by having two CICS regions talking to each other via APPC (eliminating the PC application, the WinNT / CICS TG server, and CICS application software from the picture). When we move the image, we pull the fibers from the z/890, plug them in to the z9, and IPL from the same SYSRES. Problem hits us. Pull the fibers from the z/9, plug them back in to the z/890, IPL from same SYSRES, problem goes away (read: same z/OS, same VTAM, same CICS, same application, only difference seems to be the processor....) So, z/OS 1.7 with CICS/ESA 4.1 and APPC seem to coexist nicely on a z/890. And, z/OS 1.7 with CICS/ESA 4.1 and APPC don't seem to play nicely together at all on a z9. Is anyone running with similar software levels and APPC on a z9? What's the difference between a similar sized z9 (G01) and a z/890 (140) that could cause this? Thanks to all in advance!
