Removing a spare RECON data set

There may be certain instances where you need to remove a RECON data set (for instance testing in a nonproduction system or maybe a damaged DASD).

Recommendation: For both online and batch, use dynamic allocation for RECON data sets, and run with at least three RECON data sets.

Procedure

  1. Delete the cluster.
  2. Delete DFSMDA member in IMS.SDFSRESL or remove DD statement from IMS JCL and batch JCL if you do not use dynamic allocation.
