A PowerExchange Logger for z/OS DEFINE_LOG command cannot insert additional log definitions into the emergency restart data set (ERDS) because the log data set is full. In the message text,
ddname
is the DDNAME of the full log data set.
The PowerExchange Logger aborts the DEFINE_LOG command with a return code of 8.
Use the VSAM IDCAMS REPRO command to dump the ERDS. Examine the dump to determine the current status of the ERDS. Then, correct the problem and run the job again.
