Configurable Core File Paths

Two new configurable core file paths that can be enabled or disabled independently of each other are:

• A per-process core file path, which defaults to core and is enabled by default. If enabled, the per-process core file path causes a core file to be produced when the process terminates abnormally. The per-process path is inherited by a new process from its parent process.

  When generated, a per-process core file is owned by the owner of the process with read/write permissions for the owner. Only the owning user can view this file.

• A global core file path, which defaults to core and is disabled by default. If enabled, an additional core file with the same content as the per-process core file is produced by using the global core file path.

  When generated, a global core file is owned by superuser with read/write permissions for superuser only. Non-privileged users cannot view this file.

When a process terminates abnormally, it produces a core file in the current directory as in previous Solaris releases. But if the global core file path is enabled and set to /corefiles/core, for example, then each process that expires produce two core files: one in the current working directory and one in the /corefiles directory.

By default, the Solaris core paths and core file retention remain the same:

• A setuid process does not produce core files using either the global or per-process path.

• The global core file path is disabled.

• The per-process core file path is enabled.

• The per-process core file path is set to core.
