ORA-7445 是与ORA-600齐名的著名Oracle错误，同ORA-600比较起来ORA-7445更多地由操作系统OS的异常或者bug引起。以下是ORA-7445的一些官方解释：
While the ORA-600 error is “captured” as a handled exception in the Oracle source code, the ORA-7445 is an unhandled exception error due to an OS exception which should result in the creation of a core file. An ORA-7445 is a generic error, and can occur from anywhere in the Oracle code. The precise location of the error is identified by the core file and/or trace file it produces.
Whenever an ORA-7445 error is raised a core file is generated. There may be a trace file generated with the error as well.
As the ORA-7445 error indicates an unhandled exception in the Oracle source code, your search in the Oracle Knowledge Base will need to focus on the stack data from the core file or the trace file.
