A DEFINE_LOG command was entered with a data set name that already exists in the restart data set (ERDS). An entry is made in a restart data set (ERDS) if the specified DD name currently exists in either the active or archive record of that restart data set. The variable
ddname
specifies the DD name of the specified restart data set.
The DEFINE_LOG command ends.
Either correct the data set name in the command control statement and run the command again, or delete the existing data set name from the restart data set and run the job again.
