Migration considerations for Fast Path DEDB area data sets (ADS) encryption

Install APAR PI83756 to enable this feature.

Migration considerations introduced in IMS 15

To migrate from non-encrypted Fast Path DEDB ADS to encrypted Fast Path DEDB ADS, perform the following steps:
  1. Perform one of the following methods to create encrypted ADS:
    • Define the shadow ADS with the same attributes as the non-encrypted ADS and specify key labels with the shadow ADS. Run DEDB ALTER utility.
    • Define new ADS as SMS-managed extended format DASD and specify key labels with them. Register the new ADS to DBRC by using the following command:

      INIT.ADS DBD(xxxxxxxx) AREA(yyyyyyyy) ADSN(AREA data set name) UNAVAIL

      Run CREATE utility.
  2. Stop the non-encrypted ADS if necessary.
To fallback from encrypted Fast Path DEDB ADS to non-encrypted ADS, create new ADS without key label and use the DEDB ALTER and DEDB Area Data Set Create utilities to copy encrypted ADS to new ones.
