QMErrorLog stanza on UNIX, Linux®, and Windows

Use the Extended queue manager properties page from the MQ Explorer, or the QMErrorLog stanza in the qm.ini file to tailor the operation and contents of queue manager error logs.

Attention: You can use MQ Explorer to make the changes, only if you are using a local queue manager on the Windows platform.
ErrorLogSize= maxsize
Specifies the size of the queue manager error log at which it is copied to the backup. maxsize must be in the range 32768 through 2147483648 bytes. If ErrorLogSize is not specified, the default value of 2097152 bytes (2 MB) is used.
ExcludeMessage= msgIds
Specifies messages that are not to be written to the queue manager error log. If your IBM® MQ system is heavily used, with many channels stopping and starting, a large number of information messages are sent to the z/OS® console and hardcopy log. The IBM MQ - IMS bridge and buffer manager might also produce a large number of information messages, so excluding messages prevents you from receiving a large number of messages if you require it. msqIds contain a comma-separated list of message id's from the following:
  • 5211 - Maximum property name length exceeded.
  • 5973 - Distributed publish/subscribe subscription inhibited
  • 5974 - Distributed publish/subscribe publication inhibited
  • 6254 - The system could not dynamically load shared library
  • [IBMi]7163 - Job started message ( IBM i only)
  • 7234 - Number of messages loaded
  • 9001 - Channel program ended normally
  • 9002 - Channel program started
  • 9202 - Remote host not available
  • 9208 - Error on receive from host
  • 9209 - Connection closed
  • 9228 - Cannot start channel responder
  • 9489 - SVRCONN max instances limit exceeded
  • 9490 - SVRCONN max instances per client limit exceeded
  • 9508 - Cannot connect to queue manager
  • 9524 - Remote queue manager unavailable
  • 9528 - User requested closure of channel
  • 9545 - Disconnect interval expired
  • 9558 - Remote Channel is not available
  • 9637 - Channel is lacking a certificate
  • 9776 - Channel was blocked by user ID
  • 9777 - Channel was blocked by NOACCESS map
  • 9782 - Connection was blocked by address
  • 9999 - Channel program ended abnormally
SuppressMessage= msgIds
Specifies messages that are written to the queue manager error log once only in a specified time interval. If your IBM MQ system is heavily used, with many channels stopping and starting, a large number of information messages are sent to the z/OS console and hardcopy log. The IBM MQ - IMS bridge and buffer manager might also produce a large number of information messages, so suppressing messages prevents you from receiving a number of repeating messages if you require it. The time interval is specified by SuppressInterval . msqIds contain a comma-separated list of message id's from the following:
  • 5211 - Maximum property name length exceeded.
  • 5973 - Distributed publish/subscribe subscription inhibited
  • 5974 - Distributed publish/subscribe publication inhibited
  • 6254 - The system could not dynamically load shared library
  • [IBMi]7163 - Job started message ( IBM i only)
  • 7234 - Number of messages loaded
  • 9001 - Channel program ended normally
  • 9002 - Channel program started
  • 9202 - Remote host not available
  • 9208 - Error on receive from host
  • 9209 - Connection closed
  • 9228 - Cannot start channel responder
  • 9489 - SVRCONN max instances limit exceeded
  • 9490 - SVRCONN max instances per client limit exceeded
  • 9508 - Cannot connect to queue manager
  • 9524 - Remote queue manager unavailable
  • 9528 - User requested closure of channel
  • 9545 - Disconnect interval expired
  • 9558 - Remote Channel is not available
  • 9637 - Channel is lacking a certificate
  • 9776 - Channel was blocked by user ID
  • 9777 - Channel was blocked by NOACCESS map
  • 9782 - Connection was blocked by address
  • 9999 - Channel program ended abnormally
If the same message id is specified in both SuppressMessage and ExcludeMessage , the message is excluded.
SuppressInterval= length
Specifies the time interval, in seconds, in which messages specified in SuppressMessage are written to the queue manager error log once only. length must be in the range 1 through 86400 seconds. If SuppressInterval is not specified, the default value of 30 seconds is used.
