The directory path for the Replication Agent System Database (RASD) trace log file.
When you create a Replication Agent instance, the repository directory is created automatically as part of the instance directory structure. The default value of the rasd_trace_log_dir parameter points to that directory.
If you specify any valid path as the value of the rasd_trace_log_dir parameter, the Replication Agent instance writes its RASD trace log file in that directory.
