In the test lpar, IDMS Release 18.5, I changed SVC, reassembled and linked SVCOPT, SRTT, sysgen, startup proc. Ran CAIRIM to load new SVC. I can run UCF Batch startup and the cv comes up. I can't access it through switch or vtam though. When I try to manually start it, it abends with the above message. I did talk to system programmer and he tells me the APFLIB is authorized. What have I forgotten?
