Mirroring Controller can be stopped using one of the following ways:
Using the mc_ctl command
Stopping the service
Note
Mirroring Controller must be stopped by a user with administrator privileges (user ID belonging to the Administrators group).
While Mirroring Controller is running, execute the mc_ctl command from the command prompt in stop mode to stop Mirroring Controller.
Example)
> mc_ctl stop -M D:\mcdir\inst1
Point
To stop the Mirroring Controller process only, execute the mt_ctl command in stop mode with the --mc-only option specified.
See
Refer to the Command Reference for information on how to specify the mc_ctl command.
Select [Administrative Tools], then [Services] to open the [Services] window, and then select the Mirroring Controller service and click the [Stop] menu.
Note
Before shutting down the operating system on the primary server, you must stop the Mirroring Controller, or shut down the operating system on the standby server.
If you stop the Mirroring Controller by stopping the service, you must firstly exit all applications or programs that are using the instance that is to be stopped.
When only the instance is stopped without stopping Mirroring Controller, the impact will be as follows:
When Mirroring Controller option is used
Mirroring Controller determines that an error has occurred in the instance, and performs an unnecessary automatic switch. Automatic switch may also stop working correctly in some cases.
When Mirroring Controller option is not used
Mirroring Controller determines that an error has occurred in the instance, and outputs an error to the event log.
