IMS DEDB Fast Recovery checks the IMS MODSTAT, MODSTAT2, or OLCSTAT data sets to determine the identifier (x) of the ACBLIBx data set that was in use at the time of IMS failure.

The MODSTAT and MODSTAT2 data sets contain records that determine the identifier of the ACBLIBx data set that was in use at the time of IMS failure. When the scope of the online change is global, the OLCSTAT data set contains records that determine the identifier of the ACBLIBx data set that was in use at the time of IMS failure.
