WMB password change Issues

Below is the solution to fix broker password change.

1. Fix DB2 services – The easiest way to do this is switch to services view in Windows and spot the services that are failing to start. Next right click these services and from the context menu select properties. Select the Log On tab and change the password used for these services. Please note that some services use the local system account while others use a selected account and it is these services which use a selected account that fail. (I don’t know why services use a different approach as of now so if you know I would appreciate if you can tell me)
2. Next you need to fix the service password for your configuration manager. For this you need to issue amqsichangeconfigmgr -a . Start your configuration manager by issuing a mqsistart command following this.
3. The last piece you need to fix is your broker instance. For this you need to fix both service password and data source password. Issue a mqsichangebroker -a -p . Start your broker instance by issuing a mqsistart command.
