DUMPCORE configuration parameter (UNIX)

Use the DUMPCORE configuration parameter to control 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.)

onconfig.std value
DUMPCORE 0
values
0 = Do not dump core image.

1 = Dump core image.

takes effect
After you edit your onconfig file and restart the database server.
When you reset the value dynamically in your onconfig file by running the onmode -wf command.
When you reset the value in memory by running the onmode -wm command.

Usage

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.
