The Affinity database objects
The Affinity database objects contain accumulated data about all your programs and transactions and the affinities between them.
You can also, optionally, group your transactions into applications so that you can query application affinities. Update the database objects regularly to add new information recorded by the Collector in the VSAM affinity files. CICS® IA provides a job to create the database and a suite of batch programs to update the database. See Updating the Affinity database objects for more details.
Typically, there is only one set of Affinity database objects, even if you have separate affinity data and control record files for each region being monitored. In the latter case, you would typically feed the information in every VSAM affinity data file into the one set of Affinity database objects. Using one database makes it easier to compare and contrast affinity data from different regions.
For the affinity base tables see Affinity base tables.
In addition, facilitating tables are used in the updates of the base tables.
