Our users are reporting that when they compare LIBRARIAN files that the job uses a lot of CPU and eventually ends with no result when the CPU time limit is reached.
There are 3 HYPERS that need to be applied that came out right after Librarian V4.4 was GA'd, they are RO19511, RO20689, and RO21792. There are HOLDDATA DDDEFs in PTF RO20689 and PTF RO21792 that need to be run as a standalone job. Please make sure you run the DDDEFs
After applying the HYPER PTFs, apply PTF RO20696 as it corrects S0C4 abends and possible loops.
