ORA-00600 and ORA-07445

ORA-00600 and ORA-07445 errors are the most esoteric erros in Oracle.

There is a tool called "ORA-600/ORA-7445 Troubleshooter" available at Metalink. It asks for the first argument of ORA-600 error with an optional database version number.

For example, to see the description of the error:

ORA-00600: internal error code, arguments: [723], [25908], [25908], [memory leak]

You enter 723 in the "ORA-600 First Argument" field. The first argument is a pointer to where in the code the error was caught and thus is the key information in identifying the problem.

You can also embed (copy/paste) the "Call Stack Trace" there, and, when you click on the "Search Call Stack" button an advanced MetaLink search is performed to find documents containing relevant sections from the call stack.

Call Stack extracts from the following files are supported:

Generic foreground and background server trace files located in background_dump_dest and user_dump_dest
OpenVMS NETV2 and BEQ log files located in ORA_ROOT:[NETWORK.LOG]
GDB (debugger) backtrace call stacks (best endeavors)
