Modifying the Configuration Manager

Before you start:

You must complete the following tasks:

Modify the Configuration Manager on Windows platforms only, using the command line. The Configuration Manager can only be modified on the system where the Configuration Manager component is installed.

The following steps show you how to modify the Configuration Manager.

  1. Stop the Configuration Manager using the mqsistop command.
  2. Enter the mqsichangeconfigmgr with the parameters you want to change:
    mqsichangeconfigmgr <<-i ServiceUserID> -a ServicePassword>
    <-p DatabasePassword> <-s UserNameServerQueueManagerName>
    <-d SecurityDomainName> <-j  MaxJVMHeapSize> <-l 0 | 1 | 2> 
    where:
    -i
    Is the service user ID that is used to run the Configuration Manager.
    -a
    Is the password for the Configuration Manager user ID.
    -p
    Is the password for the user ID with which the configuration repository database is to be accessed.
    -s
    Is the WebSphere MQ queue manger for the User Name Server.
    -d
    Is the security domain that the User Name Server will use, on the Windows platform.
    -j
    Is the maximum Java virtual machine heap size, in megabytes (minimum 64).
    -l
    Is the level of domain awareness for Windows (either 0, 1 or 2).
    For example, to modify the Configuration Manager so that it can communicate with the User Name Server, enter the following command at the command prompt:
    mqsichangeconfigmgr -s WBRK_UNS_QM
  3. Restart the Configuration Manager using the mqsistart command. The Configuration Manager restarts with the new properties.

If you cannot change a property using mqsichangeconfigmgr, delete the Configuration Manager and then create a new one, with the new properties. Creating a new Configuration Manager does not cause any loss of data, so long as the previous Configuration Manager's database tables were not deleted (for example by specifying the -n and -w parameters on mqsideleteconfigmgr). The configuration repository is preserved if you use the correct form of the mqsideleteconfigmgr command.
