Create a new trace class
To create your own trace class, define an entry for the trace class in the systraceclasses system catalog table.
By default, all users can view this table, but only users with the DBA privilege can modify it. You can create as many trace classes as you like. The database server prevents you from creating a trace class name that is already in use.
The following code fragment shows the INSERT statement that creates
a trace class named funcEntry.
When you insert a new trace class into systraceclasses,
the database server assigns it a unique identifier, called a trace-class
identifier. It stores this trace-class identifier in the classid column
of systraceclasses.
