Want to know how to deal with ORA-07445 error? Don’t worry can you deal with these errors as here you will get the perfect solution for it.

So, let’s get started with the diagnosis way of ORA-07445: exception encountered: core dump error.

How To Diagnose ORA-07445 Error?

If you ever come across this error, then a core file is generated and also sometimes trace file is also generated with this error.

The core file is located in the CORE_DUMP_DEST directory. In the oracle 11g database, there is a new advanced fault way of diagnosing infrastructure to manage the trace data. Diagnostic files are written into a root directory for entire diagnostic data known as ADR home. All the core files at 11g will go the ADR HOME/cdump directory.

Important: When the core file is captured in the Diagnosability infrastructure, there are chances that they may not be included in the diagnostic package.

Diagnosability infrastructure may include the following:

#1: Check the Alert Log

Checking alert log is the best option to see the additional error as well as other internal errors at the time of the problem. However, in some cases, the ORA-7445 error will take place because of the side effect of other issues. So, you need to review the main error first, its associated core file or traces file and work down the list of errors. Sometimes this error occur along with the ORA-600, ORA-3113, ORA-4030 errors, so it is suggested to fix this ASAP. You can take help from the following:

Note 1020463.6 DIAGNOSING ORA-3113 ERRORS

Note 414966.1 RDA Documentation Index

Note 1812.1 TECH: Getting a Stack Trace from a CORE file

But if the ORA-7445 errors are not associated with any of these errors then make sure that the trace data is not truncated. You may see the below message at the end of the file:

“MAX DUMP FILE SIZE EXCEEDED”

If you see so then the MAX_DUMP_FILE_SIZE parameter is actually not setup enough or to ‘unlimited’. It could be that, the Vital diagnostic information is missing in the file and finding the root cause of this error may get more difficult. So you need to Set the MAX_DUMP_FILE_SIZE appropriately and regenerate the error for complete trace information.

#2: “Fine Tune” Searches In Knowledge Base

I have already explained that ORA-07445 error indicates that there is an unhandled exception in the Oracle source code. So, the search in the Oracle Knowledge Base will be required to focus on the stack data from the core file or even the trace file.

Do not forget that the searches on generic argument data will bring back a very vast result set. It will become easier for you to narrow the hit list to tally your problem if you learn more about the environment as well as code leading to the Oracle errors.
