Creating a Mirror Replication Agent instance

You can create a Mirror Replication Agent instance at any time after the Mirror Replication Agent software is installed by invoking mra_admin with the -c option.

The complete syntax is:

mra_admin -c new_inst -p port_num

where:

new_inst is the name of the new Mirror Replication Agent instance.

port_num is the client socket port number for the administration port of the new instance.

See “Copying a Mirror Replication Agent configuration” for information about creating a Mirror Replication Agent instance based on the configuration of an existing instance.

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

You must set the SYBASE environment before you invoke the Mirror Replication Agent mra_admin utility. See “Setting the SYBASE environment” for more information.

To create a Mirror Replication Agent instance

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

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

mra_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 mra_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 mra_admin with the -v option, and specify the name of the new Mirror Replication Agent instance:
```
mra_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 mra_admin with the -l option:
```
mra_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 mra_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 mra utility to start the instance so that it can be administered and configured. See “Starting the Mirror Replication Agent” for more information.

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. See “Creating the Mirror Replication Agent administrator login” for more information.
