To facilitate troubleshooting of unexplained DBMS timeouts, you can enable the fault monitor to create a core file when a probe timeout occurs. The contents of the core file relate to the fault monitor process. The fault monitor creates the core file in the / directory. To enable the fault monitor to create a core file, use the coreadm command to enable set-id core dumps. For more information, see the coreadm(1M) man page.
