Method and system for storing trace events in a database table
According to one embodiment, a method for storing trace events in a database table includes reading a group of parameters from the table. The group of parameters includes parameters indicative of the maximum number of records, the most recently added record, and the total number of records in the table. The method further includes receiving a trace event. The method also includes storing the trace event as a record in the table based on the group of parameters. The method further includes updating the group of parameters before receiving the next trace event.

receiving a first trace event, the first trace event comprising a first condition prior to an error condition;
storing the first trace event as a record in the table based on the plurality of parameters, wherein storing the first trace event as a record comprises:
generating a record number based on the parameter indicative of the most recently added record in the table; and
adding the record to the table at the record number;
updating the plurality of parameters before receiving a second trace event;
receiving the second trace event, the second trace event comprising the error condition; and
after receiving the second trace event, continuing the tracing session.
