****************************************************************
During the peer restart, for some unknown reason,  Data Base
Restart Table (DBRT) entry for the Unit of Recovery (UR) object
was corrupted which results in program exception failure which
abnormally terminates DB2 member. The reason for a one bit
overlay is unknown at this time. However, this apar will avoid
bringing down DB2 member because of the address of one of the
DBRT objects was corrupted. The objective is to isolate the
object and keep the DB2 up.

    



Problem conclusion


    

  • DB2 restart logic is modified to avoid termination of DB2 member
due to program exception failures.
