Description:

With the r11.0 release of CA WA Restart Option, steps with the JCL parameter

RD=NR specified on the EXEC statement are treated as nonrestartable steps.

This Knowledge Document provides further details on how this affects production jobs.

Solution:

With the r11.0 release of CA WA Restart Option, steps with the JCL parameter

RD=NR specified on the EXEC statement are treated as nonrestartable steps.

This also applies if the job card statement specifies RD=NR. If the parm is specified on the job card statement, it will apply to all steps of the job thus resulting in all steps being treated as nonrestartable.

It should be noted that the same applies to JCL parameter RD=NC (if present, steps will be treated as nonrestartable).

Prior to upgrading to r11, please review JCL for the presence of the RD=NR or RD=NC parms. Consideration should be given if these should remain based on whether it is intended that steps with either of these parms present should be treated as nonrestartable. At r11 , once the parm is removed the next run of job will automatically perform 'F' format processing and steps that were previously flagged as non restartable will at that time be flagged as restartable.

If there is a need to fallback to the previous release of CA 11, steps that have been flagged as non restartable due to the presence of the RD=NR or RD=NC parameters will remain as non restartable steps until the next 'F' format processing of the job occurs. Plese note that 'F' format processing does not occur automatically at next run of job once back on r3.0.
