REPLLOGOPN, Replication subsystem could not open log file xxxx : yyyy. Logging done to zzzz
MUPIP Error: This indicates that GT.M could not find the log file or did not have access permission to open the log file. If there is another log file available (a previously opened file), GT.M writes to the other log file. If there is no other log file available, GT.M does not log.
Action: Check the log file permissions, and if permissions are correct, move the log file and specify that GT.M should log to the new location.
