A parameter is duplicated in the SYS1.PARMLIB member specified on the PARMLIB or SET command, or in member IKJTSOxx at IPL time.
The parameter is processed at its last occurrence and preceding duplicates are ignored.
When the IPL or PARMLIB command is finished, remove any duplicate parameters in the specified member of SYS1.PARMLIB.
If this message appears during a syntax check, it indicates that the record is duplicated. If an update request were to be made using this PARMLIB member, the above action would be taken by the system. The command will continue to check other records in the PARMLIB member, and other messages may be generated. Correct the duplicate records before attempting an update operation.
