Set up the user and group on Solaris

On Solaris systems, IBM MQ requires a user ID of the name mqm, with a primary group of mqm. The mqm user ID owns the directories and files that contain the resources associated with the product.

Creating the user ID and group

Set the primary group of the mqm user to the group mqm.

If you are installing IBM MQ on multiple systems you might want to ensure each UID and GID of mqm has the same value on all systems. If you are planning to configure multi-instance queue managers, it is essential the UID and GID are the same from system to system. It is also important to have the same UID and GID values in virtualization scenarios.

Solaris

The user ID value for user mqm must be less than 262,143 to avoid problems with the maintenance update process.

Create the IDs using the groupadd and useradd commands to set the UID and GID the same on each machine.

Add existing user IDs to the group on Solaris systems

If you want to run administration commands, for example crtmqm (create queue manager) or strmqm (start queue manager), your user ID must be a member of the mqm group. This user ID must not be longer than 12 characters.

Users do not need mqm group authority to run applications that use the queue manager; it is needed only for the administration commands.

Log files created by MQ Telemetry service

The umask setting of the user ID that creates a queue manager will determine the permissions of the Telemetry log files generated for that queue manager. Even though the ownership of the log files will be set to mqm.
