gtpm1m09TPF V4R1 Migration Guide: 3.1 to 4.1

Who Should Use This Publication

This publication is written for any IBM Transaction Processing Facility (TPF) customer who is migrating, or planning to migrate, from the IBM Transaction Processing Facility Version 3 Release 1 system (referred to as the TPF 3.1 system in the remainder of this publication) to the IBM Transaction Processing Facility Version 4 Release 1 (referred to as the TPF 4.1 system in the remainder of this publication).

This publication describes changes between the TPF 3.1 system and the TPF 4.1 system, and provides general information to help you plan for your TPF system migration. It does not contain specific information about planning for your migration and it does not contain information about installing the TPF 4.1 system. See the TPF System Installation Support Reference and TPF System Generation for more information about installation and system generation.

Some changes do not require any action on your part. For example, if you currently use the TPF 3.1 system without modifications and plan to use the TPF 4.1 system without making any modifications, it may not be necessary for you to make any changes. However, if you did make modifications to the TPF 3.1 system and plan to make modifications to the TPF 4.1 system, or you want to take advantage of the new functions provided in the TPF 4.1 system, then it will be necessary for you to make changes.

In addition, other changes found in the TPF 4.1 system may require you to make changes to the following to ensure the continued availability of existing functions:

Although all of these changes are discussed in this publication, required changes are the primary focus.
