How to determine if TRACE is turned on or off in NuoDB?
The following query result indicates whether the TRACE is ON or OFF:
select VALUE from system.properties where property='DB_TRACE';
More information and examples can be found here.
Note: Turning ON the trace facility should be for limited time periods. When done using the Trace facility, turn it off, otherwise it may impact database performance. Trace ON also consumes additional log file disk space.
