MySQL - InnoDB

This tab displays the result of the SQL statement:


If the message:

Access denied; you need (at least one of) the PROCESS privilege(s) for this operation

is displayed, it means that the MySQL user doesn't have permissions to execute the command.

This can be granted using the following SQL statement:

GRANT SELECT, PROCESS ON *.* TO 'openvpms'@'localhost';

Replace 'openvpms' and 'localhost' the actual database user name and host if they have been changed from their default values.

NOTE: this may not take effect until Tomcat has been restarted.
