Change queue manager configuration information
The attributes that we can use to modify the configuration of an individual queue
manager override any settings for IBM MQ .
On UNIX and Linux systems, you modify queue manager
configuration information by editing the qm.ini configuration file. When you
are defining a stanza in qm.ini, we do not need to start each item on a new
line. We can use either a semicolon (;) or a hash character (#) to indicate a comment.
On Windows and Linux x86-64 systems, we can modify some configuration
information by using the IBM MQ Explorer. However, because
there are significant implications to changing installable services and their components, the
installable services are read-only in the IBM MQ Explorer. You
must therefore make any changes to installable services by using regedit on
Windows, and by editing the qm.ini
file on UNIX and Linux.
Procedure
For more details on changing queue manager configuration information, see the following
subtopics:.
Access Mode
Access Mode applies to Windows servers only. The AccessMode stanza is set by the -a [r] option on the crtmqm command. Do not change the AccessMode stanza after the queue manager has been created.
Configure installable services
You change installable services on Windows by using regedit, and on UNIX and Linux by using the Service stanza in the qm.ini file.
Queue manager logs
Use the Log queue manager properties page from the IBM MQ Explorer, or the Log stanza in the qm.ini file, to specify information about logging on a queue manager.
Restricted mode
This option applies to UNIX and Linux systems only. The RestrictedMode stanza is set by the -g option on the crtmqm command. Do not change this stanza after the queue manager has been created. If we do not use the -g option, the stanza is not created in the qm.ini file.
XA resource managers
Use the XA resource manager queue manager properties page from the IBM MQ Explorer, or the XAResourceManager stanza in the qm.ini file, to specify the following information about the resource managers involved in global units of work coordinated by the queue manager.
Attributes of the channels stanza
These attributes determine the configuration of a channel.
TCP, LU62, and NETBIOS
Use these queue manager properties pages, or stanzas in the qm.ini file, to specify network protocol configuration parameters. They override the default attributes for channels.
Exit path
Use the Exits queue manager properties page from the IBM MQ Explorer, or the ExitPath stanza in the qm.ini file to specify the path for user exit programs on the queue manager system.
Diagnostic message logging
The diagnostic message logs of IBM MQ are a mechanism, to allow various components of the IBM MQ system, to report diagnostic messages relating to IBM MQ configuration and runtime state changes and issues.
Queue manager default bind type
Use the Extended queue manager properties page from the IBM MQ Explorer, or the Connection stanza in the qm.ini file to specify the default bind type. Note that you must create a Connection stanza if you need one.
SSL stanza of the queue manager configuration file
Use the SSL stanza of the queue manager configuration file to configure TLS channels on your queue manager.
Exit properties
Use the Cluster queue manager properties page from the IBM MQ Explorer, or the ExitPropertiesLocal stanza in the qm.ini file, to specify information about exit properties on a queue manager. Alternatively, we can set it using the amqmdain command.
Subpool
This stanza is created by IBM MQ. Do not change it.
Filesystem
By default, only members of the mqm group can write directly to error log files and First Failure Data Capture files. We can use the Filesystem stanza to allow users who are not members of the mqm group to access error directories and files.
Security
Use the Security stanza in the qm.ini file to specify options for the Object Authority Manager (OAM).
Tuning parameters
Use the TuningParameters stanza in the qm.ini file to specify options for tuning the queue manager.
