Delete GDG cluster Sample JCL Example

The below JCL you can use to delete GDG base cluster. The interesting point is if you delete the GDG base, automatically it deletes all the versions.

Sample JCL

//Step1   EXEC  PGM=IDCAMS
//SYSIN   DD   *
 DELETE 'XXXX.XXXX.XXXX.XXX' GDG FORCE
/*

Alternative JCL Example

(or) if we want to delete migrated-GDGS,  use the following syntax.

//Step1   EXEC  PGM=IDCAMS
//SYSIN   DD   *
 HDELETE 'XXXX.XXXX.XXXX.XXX' GDG FORCE
/*

Notes: To delete VSAM clusters, give CLUSTER in place of GDG.

Popular Parameters you can use with DELETE.

• FORCE: It deletes all clusters in the catalogue.

• NOFORCE: It deletes an empty catalog. If the catalog does have cluster entries, it will not delete.

• PURGE: Even though GDG has retention period, it deletes all entries.

• NOPURGE: When the GDG has retention period, it will not delete the entries.

Notes: With IDCAMS utility we can delete GDG clusters and VSAM clusters.
