There are several methods you can use to verify the status of your servers.
Use isql to log in to each server. If the login succeeds, the server is running.
Create a script that logs in to and displays the status of each Adaptive Server and its RepAgent thread, other Replication Agent (if any), and Replication Server. Make sure all servers in the script are included in the interfaces file.
If a login fails, it may be caused by one of the following problems:
DB-LIBRARY error: Server name not found in interface file.
DB-LIBRARY error: Login incorrect.
Operating-system error: Invalid argument DB-LIBRARY error: Unable to connect: Server is unavailable or does not exist.
Operating-system error: No such file or directory DB-LIBRARY error: Could not open interface file.
Operating-system error: Permission denied DB-LIBRARY error: Could not open interface file
If you cannot log in but do not receive an error message, you can assume that the server has stopped processing. Call Sybase Technical Support if you need assistance in determining the problem.
