Changing the core pattern

In some situations, the Amlen Bridge can stop with uncaught signals, such as a SIGSEGV or a SIGQUIT signal.

By default, a core dump file is generated at the current working directory with a name such as core.imabridge.27. IBM Support can inspect the core dump file to diagnose issues.

You can change the directory and the names of the core dump files. This might be especially important in the Docker environment, in which mounted storage is expected for core dump files.

You can update the core_pattern file with the necessary % specifiers. For example, run the following command: echo "/var/imabridge/core.%E.%p " > /proc/sys/kernel/core_pattern.

For more information about the core pattern, see the section about core in the Linux Programmer's Manual.
