Sometimes it can be useful to see what queries are processed by the database service.
To enable the logging of queries a message has to be sent to the database service:
/opt/visulox/bin/cmd/msg.tcl -to database -command DEBUG-SQL -sqldebug 1
The queries can be seen in database.log.
To disable logging set the flag to "0".
To query the state, just send the DEBUG-SQL command.
