Creating a Mirror Replication Agent using the command line

Use the following procedure to create a Mirror Replication Agent instance using the command line.

You must set the SYBASE environment before you invoke the Mirror Replication Agent mro_admin utility. For more information see “Setting the SYBASE environment”.

To create a Mirror Replication Agent instance using the command line

Open an operating system command window on the Mirror Replication Agent host machine.

At the operating system prompt, navigate to the Mirror Replication Agent bin directory.

On Microsoft Windows platforms, enter:
```
cd %SYBASE%\MRO-12_6\bin
```
where %SYBASE% is the path to the Mirror Replication Agent installation directory.
On UNIX platforms, enter:
```
cd $SYBASE/MRO-12_6/bin
```
where $SYBASE is the path to the Mirror Replication Agent installation directory.

In the Mirror Replication Agent bin directory, invoke the mro_admin utility to create a new Mirror Replication Agent instance:

mro_admin -c new_inst -p port_num

where:

new_inst is the name of the Mirror Replication Agent instance.
port_num is the client socket port number for the administration port of the new instance.

After you invoke mro_admin, the operating system prompt returns when the new Mirror Replication Agent instance is created.

Verify that the Mirror Replication Agent instance was created properly using one of the following methods:

Invoke mro_admin with the -v option, and specify the name of the new Mirror Replication Agent instance:
```
mro_admin -v new_inst
```
where new_inst is the name of the new Mirror Replication Agent instance.

When you verify a Mirror Replication Agent instance with the -v option, the utility verifies the instance by checking for an instance directory with the specified instance name under the Mirror Replication Agent base directory, and checking all of the subdirectories under the Mirror Replication Agent instance directory.
Invoke mro_admin with the -l option:
```
mro_admin -l
```
The -l option lists all verifiable Mirror Replication Agent instances, which should include the new one you just created.
As an alternative to using the mro_admin utility, you can use operating system commands to verify that the Mirror Replication Agent instance directories were created correctly (as shown in Figure 2-1).

After you create a Mirror Replication Agent instance, you can use the mro utility to start the instance so that you can administer and configure it. For more information, see “Starting the Mirror Replication Agent”.

Sybase recommends that you create a user login name and password to replace the default “sa” login and secure access to the administration port, immediately after you create a Mirror Replication Agent instance. For more information, see “Creating the Mirror Replication Agent administrator login”.
