52 Finding Capture Points CICS Interdependency Analyzer Use CICS IA to discover Which transactions update which resources e.g. where is my PIN number file updated? where are order numbers read from the TS queue? The runtime flow e.g. which program is linked to when an insurance quote is requested? Ensure capture specification filters are sufficiently specific How many programs use this resource? Can also use CICS IA Plugin to CICS Explorer 52
