BAS allows you to create CICSPlex® SM objects that define your resources and
to group them in such a way that you have close control over the running of
your applications. You do not have to transfer all your CSD resources to CICSPlex SM at
the same time, neither do you have to decide at the outset which approach
you will use. You can extract the resource definition records from one or
more CSDs, or only a subset of records from one CSD. You can move directly
to using full-function BAS, or you can use migration form BAS, and gradually
move towards full-function BAS. You can use RDO, migration form BAS, and
full-function BAS in the same CICSplex.
This topic poses some of the questions you might like to consider when
you start planning to implement BAS in your enterprise:
- If you are going to use the extract facilities:
- In what order do you want to extract your CSDs?
- Do you want all the records from a CSD or a subset?
- Are you going to extract more than one CSD at a time?
- Are you going to use the migration form approach?
- Are you going to implement full-function BAS? You then need to think
about how your business applications use resources and the assignments you
need to create.
- Which resources are to be installed automatically and which are to be
installed dynamically?
- Where are the resources to be installed?
- Do you need to define manually any resources that are not defined in the
CSD?
- What security measures do you need to implement? (See Security considerations).
The IBM® CICS Interdependency Analyzer for z/OS® can assist you in the planning and understanding
of your application resource flow; it shows you:
- Transaction resource dependencies; that is, the sets of resources used
by individual CICS transactions, and on which the transactions depend in order
to run successfully
- Transaction affinities; that is, those groups of transactions that have
affinities with each other, meaning that the whole group must be installed
in the same region, or in a particular region
