ORA-00600: internal error code…

ORA-00600 errors indicate internal exceptions which are handled by the Oracle Kernel.

In contrast, the error messages ORA-07445: exception encountered: core dump indicates an OS exception that is not handled by Oracle.

This error comes with multiple arguments/parameters.

The first parameter of the ORA-00600 error message is either a

number, which reflects the source component or layer the error is connected with, or a
mnemonic which indicates the source module where the error originated.

The mnemonic is preferred.
