I have a MQ program. As of now the program is started manually the first time. Every time it is invoked it processes 10 messages and ends. before it ends it issues command to start itself after 30 sec and the process goes on. This MQ program call program A and program inturn calls program B. All this works fine in one region. when i moved the same program to different region i am getting ASRA abend. That too when the MQ program is started for the first time it process the messages and goes off. only when it auto invokes itself and only if there is any message it abends. when it process the first message after auto invocation it abends in program B with ASRA. (program A & B are already existing program where there could be no problem with logic). the interruption code is 0010 which means segment translation exception. can any one explain what it means and the reason for it in my case.
