Abstract:
Various embodiments for failure recovery in a computing environment following a data restoration are provided. A catalog locate is performed for each of a plurality of data sets on a base catalog structure (BCS), identifying a plurality of BCS entries. If a first BCS entry is cataloged incorrectly, the first BCS entry is designated to be re-cataloged. The plurality of BCS entries is compared with a plurality of volume table of contents and a plurality of VSAM volume data set (VTOC/VVDS) entries. If a second BCS entry found in the plurality of BCS entries is not found in the plurality of VTOC/VVDS entries, and the second BCS entry indicates that a data set associated with the second BCS entry is located on a volume, an attempt is made to vary on the volume. If the volume cannot be varied on, a request is created to restore the volume.
