Database error messages are generated when there is an error during database operations. For example, most database errors are internal errors.
There are two kinds of database-related errors:
Errors during MySQL database initialization
This is typically an internal error while inserting or updating a specific table in the MySQL database. Check the server environment and make sure that the MySQL server is running. Refer to Installation FAQs to determine if the error message is related to the installation of MySQL.
Errors related to the VRC database operations, such as:
Removing an element from the dial plan
When you encounter database error messages, use the console to set the debug of the Database subsystem to on. However, a database error might be caused by any VRC operation. In these instances, determine which operation caused the error, and debug the subsystem related to that operation.
Some database errors require you to stop the VRC server and then restart it. Continued use of this corrective action should be reported to Cisco Technical Support.
If you encounter errors with the database schema, you must reinstall the VRC software and reconfigure the database.
