Error description
Enable PRF 2.1 to use PRF 2.2 Checkpoint Data Sets (CTA, CTB, CTX). This will be needed for conversion between releases when a fallback or fall-forward is required. See similar APAR required for PRF V220: PI48002

Problem summary
**************************************************************** * USERS AFFECTED: All Users of Program Restart Facility V2R1 * **************************************************************** * PROBLEM DESCRIPTION: 1. During migration from PRF V2R1 to * * V2R2, installations may require the * * ability to restart abended IMS Batch * * and/or BMP Jobs such that V2R2 can * * use V2R1 created checkpoint data sets * * (CTA, CTB, CTX) for restart. * * * * 2. In the event that PRF V2R2 fails to * * function as expected, installations * * may require the ability to fallback to * * PRF V2R1. This includes the ability * * for V2R1 to use PRF V2R2 created * * checkpoint data sets (CTA, CTB, CTX) * * for restart. * **************************************************************** * RECOMMENDATION: Apply the PTF that corrects this APAR. * * * * If you intend to take advantage of the * * capabilities added by this APAR, you must * * apply PI48002 to IMS PRF V2R2. * * * * Work very closely with IBM Support if * * this enhancement is to be employed at your * * installation. Advanced planning and testing * * are strongly recommended. * **************************************************************** 1. An IMS Batch or BMP job has abended in a PRF V2R1 environment. The installation requires that the abended job be restarted in a V2R2 environment. This is potentially useful during migration from V2R1 to V2R2. 2. An IMS Batch or BMP job has abended in a PRF V2R2 environment where V2R2 failed to operate successfully. The installation requires that the abended job be restarted in a V2R1 environment. This is potentially useful during early V2R2 deployment.
Problem conclusion
Temporary fix
Comments
1. In V2R2 APAR PI48002, PRF V2R2 is changed such that it places its version and release in the X'20' records of its CTA/CTB data sets. This allows V2R1 to recognize their origin, effect an internal format change, and make use of the V2R2 created CTA/CTB data sets for IMS Batch and/or BMP job restart. 2. In this APAR, PRF V2R1 is changed such it places its version and release in the X'20' records of its CTA/CTB data sets. This allows V2R2 to recognize their origin, effect an internal format change, and make use of the V2R1 created CTA/CTB data sets for IMS Batch and/or BMP job restart. 3. If one or the other, or both APARs are not installed, there is no negative effect. 4. There are no changes required to the CTX dataset because V2R1 and V2R2 CTX datasets are of the same format and completely interchangeable.
