Error Message: OpenLink Communications Line Broken

"OpenLink Communications Line Broken" errors may occur under a variety of circumstances. To resolve these, try the following:

1. Confirm that your ODBC DSN targets the correct Broker Listen port. This is the port on which your OpenLink Request Broker listens, as specified by the Listen keyword in the [Protocol TCP] stanza of the Broker Rulebook (oplrqb.ini by default). The default value is 5000.
   
   • Do not use port 8000, unless you deliberately configured the Request Broker -- not the Admin Assistant -- to listen on 8000.
     
   • Do not use the port at which your actual database listens.
     
     
2. Review the Broker Log for any reported errors. If the client-side error can be predictably recreated, restart the Broker in DEBUG mode (e.g., oplrqb +debug), and trigger the error while watching stdout. Report any error messages you observe here, especially if they are not preserved in the Broker log.
   
   
3. Check your network for extended intermittent failures.
   
   
4. If the problem persists, contact OpenLink Product Support.
