DUMPCORE controls whether assertion failures cause a virtual processor to dump a core image. The core file is left in the directory from which the database server was last invoked. (The DUMPDIR parameter has no impact on the location of the core file.)

Warning:
When DUMPCORE is set to 1, an assertion failure causes a virtual processor to dump a core image, which in turn causes the database server to abort. Set DUMPCORE only for debugging purposes in a controlled environment.

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

% onutil
1> SET DUMPCORE 1;
