Managing and Troubleshooting a System Using Core Files and Crash Dump Information

Troubleshooting involves preparing to handle system problems such as system hangs, crashes, or failures to reboot. When a process terminates abnormally, a core file is generated which you can examine. You can customize the default processes that create crash dump files and core files. You can use various Oracle Solaris tools to investigate what has caused a specific problem. You can then make corrections to the system.

For a description of common system problems and ways to troubleshoot them, see Troubleshooting System Administration Issues in Oracle Solaris 11.4.

Additional tools are available for troubleshooting. Oracle Solaris includes an architecture for building and deploying systems and services that are capable of predictive self-healing. The FMA receives data related to errors, automatically diagnoses the problems, and attempts to take faulty components offline. For information about fault management, see Managing Faults, Defects, and Alerts in Oracle Solaris 11.4.

A separate guide exists for troubleshooting networking issues. See Troubleshooting Network Administration Issues in Oracle Solaris 11.4.
