Instance owner unable to access core file

The instance owner is sometimes unable to access the core file for a core file that is produced during server initialization. Follow the steps to work around this issue.

If the root user starts the server, a core file might be produced early during initialization of the server. The core file might not be accessible to the instance owner user. Instead, the root user has access to the core file.

If this error occurs, the root user can manually set the core file's ownership to the instance owner user if required.

This problem occurs only on AIX® and Linux™ operating systems.
