To start a Mirror Replication Agent instance, you must log in to the Mirror Replication Agent host machine, with a user name that has execute permission in the Mirror Replication Agent installation directory and all subdirectories (for example, the “sybase” user).
There are two ways you can start a Mirror Replication Agent instance:
Invoke the generic mra utility and specify the instance that you want to start
Invoke the RUN script for the instance that you want to start
The mra utility and the RUN script are batch files on Microsoft Windows platforms and shell scripts on UNIX platforms.
