As part of its initialization, it will signon to the Post-Log Merge task to verify proper serialization and sequencing of log records being merged from all the member Loggers. The message text includes the job name of the member Logger, the SMF id of the system on which the member Logger is executing, and the name of the log reader whose status has been changed to recognize that the member Logger is now active. The message is issued once for each active log reader that will receive data merged from that member Logger. Processing continues.
