Reset the logs. If using 6-byte RBAs, allowing the log RBA to reach the maximum value of X'FFFFFFFFFFFF' will result in an unplanned outage, and the queue manager needs to be restarted. For information about how to reset the logs, refer to IBM MQ documentation.
NOTE: When the queue manager is set to use 8-byte RBAs, you should be using a situation testing the 8-byte RBA value instead of the example in this situation based on 6-byte RBAs. The attribute name to test for 8-byte RBAs is "UOW Start RBA 8 Bytes", which is a 16-byte hex character string. The comparison value would be larger in that case.
