How can I use MQ to determine what is connecting to the queue manager?
I have many connections to the queue manager but I do not have a way to determine what these connection are for or who is making them. How can I use MQ to determine what is connecting to the queue manager?
Please use the following RUNMQSC command to get more information about what is connecting to the queue manager:
Open command prompt
[Enter:] runmqsc [Qmgrname] > [path]\qmgr_conn.txt
[Type the following two lines exactly as shown]
DISPLAY CONN(*) TYPE(ALL) [Enter] END [Enter]
You should now have a file that shows all connections to the queue manager by several indicators that looks similar to this section for the SYSTEM.CLUSTER.REPOSITORY.QUEUE:
AMQ8276: Display Connection details.
CONN(BA00FD5620000401)
EXTCONN(414D5143514D31202020202020202020)
TYPE(*)
PID(7272) TID(1)
APPLDESC(WebSphere MQ Cluster Repository)
APPLTAG(ebSphere MQ\bin\amqrrmfa.exe) APPLTYPE(SYSTEM)
ASTATE(NONE) CHANNEL( )
CONNAME( ) CONNOPTS(MQCNO_FASTPATH_BINDING)
USERID(MUSR_MQADMIN) UOWLOG( )
UOWSTDA(2016-03-31) UOWSTTI(07.49.32)
UOWLOGDA( ) UOWLOGTI( )
URTYPE(QMGR)
EXTURID(XA_FORMATID[] XA_GTRID[] XA_BQUAL[])
QMURID(0.263) UOWSTATE(ACTIVE)
OBJNAME(SYSTEM.CLUSTER.COMMAND.QUEUE) OBJTYPE(QUEUE)
ASTATE(NONE) HSTATE(ACTIVE)
OPENOPTS(MQOO_INPUT_EXCLUSIVE,MQOO_INQUIRE,MQOO_SET)
READA(NO)
OBJNAME(SYSTEM.CLUSTER.REPOSITORY.QUEUE)
OBJTYPE(QUEUE) ASTATE(NONE)
HSTATE(INACTIVE)
OPENOPTS(MQOO_INPUT_EXCLUSIVE,MQOO_BROWSE,MQOO_OUTPUT)
READA(NO)
Carefully review the the USERID, APPLDESC and APPLTAG parms.
Suggest filtering out the queue manager internal connections by using a slightly enhanced version of the command suggested - also remember to say ALL as well as TYPE(ALL) to get all the attributes returned.
DISPLAY CONN(*) TYPE(ALL) ALL WHERE(APPLTYPE NE SYSTEM)
