If you try and create a new Oracle database (either using DBCA or manually) and get the
Oracle ORA-00600: internal error code, arguments: [keltnfy-ldmInit], [46], [1], [], [], [], [], [] error, this usually signifies that there was a problem resolving your server’s hostname.
Solution:
Oracle needs to be able to resolve your server’s hostname from within the server on which you are installing Oracle. In case of the above error check your /etc/hosts file and verify that your server hostname is pingable.
