When you install WebSphere MQ, default access permissions are set up for the AMQMSRVN process. These default access permissions grant access to the process to:
These permissions restrict access to the alert monitor task bar application and the amqmdain command to these users and groups only. Other users trying to access these functions are denied access. The WebSphere MQ Explorer uses amqmdain to start and end queue managers. If the WebSphere MQ Explorer is run by a user not authorized to run amqmdain, then an error is reported when the user attempts to start or stop a queue manager.
Before users run the WebSphere MQ Explorer, you must configure the access permissions of the objects involved. Use a tool called DCOMCNFG.EXE, shipped with Windows systems, to do this.
To start DCOMCNFG.EXE on Windows 2000:
To start DCOMCNFG.EXE on Windows XP or Windows 2003:
A list of applications is displayed. From this list:
On Windows XP or Windows 2003, right-click IBM MQSeries Services, then click Properties.
This displays information about the location of the DCOM server (AMQMSRVN.EXE), together with its identity and security properties.
In addition to being able to add to the list of users that are allowed access to a service, you can deny access to specific users and groups. This means that you can grant access to a group of users (by specifying a group name) but deny access to individuals within that group.
