Published by admin on January 16, 2016

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.

Introduction

Oracle specific error number is quiet common error that most of you must have got while handling oracle database. Looking up this error number in the database error messages manual will typically give you an indication of the cause of the error and the solution necessary to fix it.

Have you observed an ORA-07445 error reported in your alert log?

While the ORA-744 error is “captured” as a unhandled exception error due to an OS exception which should result in the creation of the core file. Actually it’s a generic error and can occur anywhere in the oracle code. To identify its location you need to check the core file or to trace the file that it produces.

This error may be caused even when something wrong happened in the database but they actually indicate that something disastrously happened.

Looking for the best way to diagnose?

Whenever this ORA-7445 error is comes, a core file is generated and sometime 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 diagnosability 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.

Note: When the core file is completely getting captured in the Diagnosability infrastructure, the chances are that it may not be included in the diagnostic package.

Check the Alert Log

The alert log is best option to see the additional error or other internal errors at the time of the problem. In some cases the ORA-7445 error will occur due to the side effect of other problem so you need to review the main error first, its associated core file or traces file and work down the list of errors. Because sometime this error occur along with the ORA-600, ORA-3113, ORA-4030 errors. So to fix this you can take help from the following:

Note 1020463.6 DIAGNOSING ORA-3113 ERRORS

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

Note 414966.1 RDA Documentation Index

But if the ORA-7445 errors are not associated with any of these errors then ensure the trace data is not truncated. If you see a the following message at the end of the file

“MAX DUMP FILE SIZE EXCEEDED”

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

The chances are that while fixing this error you may caught with the issue where your oracle database leads toward the corruption and lastly lead you to a situation where you are inaccessible to use it. so if somehow due to any of these error your oracle database get corrupted then the best solution with which you can go is to make use of Oracle Repair Tool which is a powerful and comprehensive recovery software that is mainly designed to recover corrupt or damaged Oracle database file. This software searches all Oracle databases which is present in the system and also shows preview of recoverable database objects. This software restores data from both database and backup files. This software saves recovered data as Transact-SQL script.

Steps to use Oracle file repair tool to repair and restore Oracle dmp file

Step 1: Search Initial screen of Stellar Phoenix Oracle Recovery with a pop-up window showing options to select or search corrupt Oracle databases in your computer.

Step 2: Click Scan File to initiate the scan process after selecting the oracle database. The recoverable database objects get listed in left-side pane.

Step 3: Click an object to see its preview.

Step 4: : Click Start Repair in the icon bar to start the repair process. A pop-up window is displayed which show the steps needed to perform further. Click next and continue.

Step 5: Give the user name, password and path of the blank database where you want to save the repaired database objects.

Step 6: Repairing and restoring various database objects after establishing a connection with blank oracle database.
