INGDYN with Db2 backend is unfinished feature

Db2 has been introduced as backend of the INGDYN. Since we don't have OMVS file sharing the SA database will not work with HA. This is why we started to use Db2 as backend for INGDYN.

Everything worked so far, until a reIPL has happened. Even having HA Db2, when the first IPL is done in the plex, Db2 is not available at IPL time for obvious reasons. Dynamic resource are defined half way after it: they are visible on INGLIST but not on DISPSTAT. With the SA database, this is solved because when that is UP it triggers automation to finish the dynamic resource creation.

Case has been open to IBM who updated to document that it is a normal behavior (although it makes the whole Db2 backend unusable and unstable imho). Currently no existing instruction from IBM how to recover from this status without re-creating the resources, IBM advised to open an idea for the bug fix.

My current workaround is to save the generated resources parameters via command exit, then after Db2 is UP, it checks which dynamic resource is half created then re-create it. Disadvantage of this solution is that with re-creation all flags and votes are also removed from the resource. 

  • It would be nice to have a script that I can manually run after Db2 is UP (e.g.: at post-start) which would finish the creation of the resources. 
  • Alternatively, dynamic resource data could be stored on global variables (like rest of SA policy) and in this case no issue with availability of external database.

    Good idea and I support it completely. Seems like a serious oversight on IBM's side and it should be fixed.
