How affinity data is collected

The Collector uses tables in a data space to hold collected affinity data.

The main affinity-related tables are of the following types:
  • The affinity group table, which records every affinity-transaction-group; that is, every group of CICS® transactions that have been grouped together because they have the potential to create the same type of affinities.
  • The affinity command table, which records every unique combination of:
    • EXEC CICS command with the potential to create an affinity
    • Program
    • Transaction ID

The affinity tables reside in the data space. The affinity group and affinity command tables are saved to VSAM files when you stop the Collector and, optionally, at predetermined intervals.
