Issue/Introduction

Description:

We are looking to use IBM ICSF (Integrated Cryptographic Service Facility) encryption on some IMS databases. We need to know if Compress for IMS supports encryption and if there are any restrictions; such as an IMS database cannot have both encryption and compression on the same database.

Solution:

You can use the IMS segment data encryption function as described in IBM Data Encryption for IMS and DB2 Databases. However, it is implemented by coding the encryption exit as the DBD COMPRTN parameter. This means you can use either Compress for IMS (COMPRTN=IMSHRINK) or encryption (COMPRTN=encryption exit) but not both.
