Defining recovery attributes for RLS and non RLS files

How to define the recovery attributes for files managed by CICS® file control.

You specify recovery options, including forward recovery, either in the integrated catalog facility (ICF) catalog or in the CICS file resource definition, as follows:
  1. If your VSAM data sets are accessed by CICS in RLS mode, define the recovery attributes in the ICF catalog. The recovery options on the CICS file resource definitions (RECOVERY, FWDRECOVLOG, and BACKUPTYPE) are ignored if the file definition specifies RLS mode.
  2. If your VSAM data sets are accessed by CICS in non-RLS mode, define the recovery attributes in either the file resource definition or the ICF catalog. If you use the ICF catalog to define attributes for data sets accessed in non-RLS mode, the ICF catalog entry recovery attributes override the CICS file resource definition.
    Note: CICS uses the ICF catalog definitions only when you specify RLS=YES as a system initialization parameter. If you specify RLS=NO, recovery attributes are always taken from the CICS file definition.
