DUMPCNT specifies the number of assertion failures for which one database server thread dumps shared memory or generates a core file by calling gcore. An assertion is a test of some condition or expression with the expectation that the outcome is true. For example, the following statement illustrates the concept of an assertion failure:

if (a != b)
   assert_fail("a != b");

To modify the DUMPCNT parameter dynamically, use the onutil SET command. Example:

% onutil
1> SET DUMPCNT
