The trace level set up relies on two Database tables.

The first, Database sp420_trace_levels, allows for the definition of the basic trace levels that are supported. This set is directly dependent on the code and, as such, is pre-loaded by ServicePower - the Database spec gives details of this.

The second is Database sp412_trace_masks, which is the one that includes the trace_mask_no that is used within other parameters, command lines etc. Each trace_mask_no identifies a trace_mask that is a bitwise combination of all of the individual trace_levels that are required within the specific grouping. Again, this table is shipped with some pre-defined values - those that ServicePower see as the most useful settings. The definitions of these existing trace_masks may be changed (not advised), or new trace_masks added as required.
