Use the following steps to recover a damaged BCS entry:

1. Remove the sphere or base record, if it exists.

   The damage detected might not be in a sphere or base record. If it is not, the entry name of the sphere or base record is indicated in messages IDC21364I and IDC21365I.

2. Remove any remaining association records.

   You can re-execute the DIAGNOSE command after you remove the sphere or base record to identify any unwanted truename or association entries in the BCS. You can remove these entries by using the DELETE command with the TRUENAME parameter.

3. Reintroduce the removed entries into the catalog.

   After the damaged entries have been removed, you can redefine the data sets. For VSAM and SMS-managed non-VSAM data sets, you should specify the RECATALOG option of the DEFINE command.

If you are recovering generation data group entries, use the same procedure. However, you must reintroduce the current generation data sets into the catalog in the proper order after the generation data group has been redefined. You can use the LISTCAT command to determine the current generation data sets.
