Prevent IMS abend U0904 during MFS online change

During the /MODIFY COMMIT of a FMTLIB type online change, if IMS detects an invalid entry in the directory of the new FORMAT library it will abend with U0904. The invalid directory could be caused by mistakenly linking a load module into the library. We would like for IMS to do an integrity check of the format library directory and prevent the COMMIT and the abend if an invalid entry is found.

    This requirement has been addressed in IMS V14 APAR PI71982/PTF UI43200.
    Online change commit will now be rejected, instead of abending IMS, if an invalid MFS format is detected in the FMTLIB.

    Hello!
    We at Volvo IT agree that it would be a very good idea to avoid U0904.
    We have had a few U0904 abends in production systems, and as MODIFY FMTLIB and contents of FMTLIB is not managed by us in the IMS infrastructure team, we cannot guarantee that it will not happen again. And it always feels a little bit embarrassing to try to explain to our customers why the IMS production system suddenly abended.
