Error description

  • IAYLSTNR sometimes gets a dynalloc failure while attempting to
    retrieve information from Changeman;
    
    The ddname it is attempting to allocate one member that is
    already in-use by another library allocated to IAYLSTNR.
    

Local fix

  • N/A
    

Problem summary

  • The existing AD Connect dynamic allocation routine had no
    recovery routine to handle the case where the IAYPDS* DDNAME was
     previously allocated and, for some reason, not deallocated when
     servicing a previous request.  This would lead to dynalloc
    reason code x410.
    

Problem conclusion

  • This APAR added a recovery routine that would first deallocate
    the existing allocation, then re-attempt the new allocation on
    IAYPDS*.  It is safe to deallocate the old allocation since each
     AD Connect subtask has its own dedicated IAYPDS* DDNAME, eg
    task #1 owns IAYPDS01, task #2 owns IAYPDS02, etc. so there is
    no way that the old allocation could be needed any more if the
    subtask has moved on to service a new request.
