Using a backup queue manager as described in the IBM MQ product documentation below: https://www.ibm.com/support/knowledgecenter/SSFKSJ_8.0.0/com.ibm .mq.con.doc/q018610_.htm The queue manager has initially been activated as described below: > strmqm -a XYZ WebSphere MQ queue manager 'XYZ' is being activated. The queue manager is associated with installation 'abc'. WebSphere MQ queue manager 'XYZ' activated. mqm@test123 (0) 10:36 12/12/17 /var/mqm . After running the update command, "strmqm -r", an infinite loop can occur on the activated queue manager. If no new logfiles have been copied to /mqlog/XYZ. . The following example demonstrates this: . mqm@test123 (0) 10:36 12/12/17 /var/mqm > strmqm -r XYZ WebSphere MQ queue manager 'XYZ' is being started for replay. The queue manager is associated with installation 'abc'. 11 log records accessed on queue manager 'XYZ' during the log replay phase. 11 log records accessed on queue manager 'XYZ' during the log replay phase. 11 log records accessed on queue manager 'XYZ' during the log replay phase. ... ... .

**************************************************************** USERS AFFECTED: Users using a backup queue manager or queue managers running with linear logging.
