The directory path for the Replication Agent System Database (RASD) transaction log file.
When you create a Replication Agent instance, the repository directory and RASD transaction log file are created automatically. The default value of the rasd_tran_log parameter points to that transaction log file.
If you specify any valid path and RASD transaction log file name as the value of the rasd_tran_log parameter, the Replication Agent instance looks in that directory for its RASD transaction log file, with the name you specified.
