Maximizing CICS transaction abend analysis performance

To maximize CICS® transaction abend analysis performance, the following should be considered:

Using the Fault Analyzer IDIS subsystem to manage the access to history file $$INDEX members. For details, see Caching of history file $$INDEX data.
Using the DeferredReport option. For details, see DeferredReport.
You can specify this option via the IDIOPTS DDname, as explained in Specifying CICS options through the IDIOPTS DDname, if you want to make it applicable to CICS® only.
