DUMPDIR specifies a directory in which the database server dumps shared memory, gcore files, or messages from a failed assertion. Because shared memory can be large, set DUMPDIR to a file system with a significant amount of space.

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

% onutil
1> SET DUMPDIR "/tmp/ifmx_dump";
