New feature PTF LU00957 has been released! This feature adds support for the IMS Catalog in CA File Master Plus for IMS v12.
The feature PTF enables File Master Plus for IMS users to access a database using an ACB from the IMS catalog. Users can enter a full or partial ACB name or no name at all, in which case an ACB is dynamically generated.
This functionality is available in the:
Why do IMS-managed ACB(s) matter?
First things first, IBM provided guidance that IMS management of ACB(s) will be required in the future, although no exact date has been set. We assume the feature is still not mature enough to be made a requirement. Even after announcement, it will be some time before the requirement will be fully "enforced". Why? It comes down to requirements for process changes that cost time and resources as well as other prerequisites (though we won't go into all of that here).
For those already familiar with the concepts of the IMS database, you are well aware of the need to create your DBD(s), PSB(s) and to ultimately join that information in ACB(s). The Database Definition (DBD) defines the IMS database. The Program Specification Block (PSB) defines the program(s) that will access the specified database. The ACB (Application Control Block) is a kind of merge of the DBD and PSB. Upon defining these elements, you still need to "do a gen", i.e. DBDGEN, PSBGEN and ACBGEN. Upon completion, you are left with all the libraries. Let's call this an 'old' environment. Should you decide to go 'modern', you'll still have all your old libs to deal with, but you can use IBM's DFS3UACB utility to populate the IMS catalog.
What are the advantages of IMS-managed ACB(s)?
There are several benefits in using IMS-managed ACB(s), and we assume these are the most important:
