The issue occurred at GDDR 5.2 (GD52115) and Mainframe Enablers V8.5.
Cause
The utility does not clear or reset the RUND variables when run in stand-alone fashion resulting in an ever-increasing length of the value for the RUND variables, ultimately leading to the invalid value message described in the GDDR992E error message.
Resolution
Workaround:
There is an immediate workaround to temporarily stop the GDDR992E error message from being issued. From the GDDR ISPF panels, use the Maintenance then the System option to delete the global variable GLOBAL.GDDR.RUND.GDDDLVSX.GDDDLVSX.RC. This prevents the GDDR992E error from occurring for approximately the next 20 executions of the DR test job.
