Bypass processing

If the MTO specifies TRCF=N when restarting the IMS system, no RCF processing will be done.

For example:

S procName,TRCF=N

This feature is designed to permit the user to bypass RCF processing during start-up of some systems, and to permit IMS system start-ups in circumstances where the services of the RCF are not desired. Examples of a situation where RCF would be bypassed include:

  • The first start-up of a new IMS system
  • Upgrading to a new release of IMS
  • The start-up of IMS surveillance systems in XRF environments.

When TRCF=N is specified:

  1. RCF issues checks for and attempts to delete any RCF-created ENQs for this IMS system.
  2. RCF issues an RCF0005I WTO message and immediately terminates normally with a return code 10. No database integrity or system resource status checking is done. No backups of MSDB-related data sets will be done.

  3. The MTO is entirely responsible for ensuring RDS data set usability and that the following:

    • Database integrity is maintained.
    • The correct IMS restart will be performed.

    Note

    After RCF has been used with an IMS system, BMC recommends that you specify TRCF=N as the only method to bypass RCF processing. Do not perform an AUTO=N restart with the RCF steps removed from the IMS procedure.
