DEDBs with MADS

IMS Database Recovery Facility attempts to recover the first unavailable area data set in the area data set list.

If the area is restored from an SMS image copy that was generated by the image copy 2 utility, the area data set that is restored is the one that was dumped to create the image copy.

Note: IMS Database Recovery Facility's recovery of MADS (multiple area data sets) differs from IMS Database Recovery Utility (DFSURDB0) processing.

IMS Database Recovery Facility requires at least one area data set in the area data set list to be unavailable.

When using DFSURDB0, the RECON recovery-needed flag must be set for recovery of MADS.

When using IMS Database Recovery Facility, this flag does not need to be set.
