hi, initially you can check trace files also to get to know what the problem is.
you can look in metalink for ora-600 lookup tool which provides information for ora-7445 errors also.
if not found anything, then raise a SR with oracle support

ORA-07445: exception encountered: core dump during database open

Hi,
after running OracleXE for 1 year on my notebook, I am running into a strange problem. During startup of the database ( opening the DB ) I get the following error:
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [__VInfreq__kmmlrl+6329] [PC:0x2D7DF01] [ADDR:0x8] [UNABLE_TO_READ] []
I then tried to reinstall the DB but the problem persists. I have no clues what influences this error.
Any ideas welcome

The machine is a notebook which is remotely administrated. The admin says there has not been a major software update.
The notebook has 2 GB of main memory and 4 GB of free disk space.
The database was up and running since 1 year. The first time I ran into this problem, was when I dropped a user from database. But that for sure was not the reason, as I totally removed oraclexe and reinstalled it from scratch and the problem persists.
Interestingly the installation doesn't fail, but the final startup, so it might be one of the last packages being installed which produces the error.
I'm looking forward to find some more details.

I'm getting ORA-07445 [kksLockDelete()+465] errors on a 10.2.0.3 Database

Hello
I am getting the following Error on our database when I run a procedure that takes many hours to complete:
Mon Aug 23 10:39:43 2010
Errors in file /oracle/admin/HLBCP/bdump/hlbcp_j000_27898.trc:
ORA-07445: exception encountered: core dump [kksLockDelete()+465] [SIGSEGV] [Invalid permissions for mapped object [0x000000048] [] []
It seems that when the DB is under pressure or a select with a large result set is executed this error occurs, and kills my procedure
As I understand that SIGSEGV refers to OS (C Compiler) / Hardware issues? Is this correct?
How can I test the OS and Compiler to ensure they are in a healthy condition?
I Currently have an SR opened with Oracle but they are saying that 10.2.0.3 is desupported and will not be able to provide a fix.
Upgrading to 10.2.0.4 is not an option for us.
This particular database is contingency database (Using Dataguard)
However from time to time we taken a Copy of the Contingency database and open in it on the contingency server to test it.
(hence we discovered this issue)
I am convinced that the issue we are having is hardware/OS related, as it does not happen on our Live Database which is on a different server.
Has anyone encountered this issue before?
How did you resolved it?

Linux 10g versus Windows XP 10g Issue - ORA-07445: exception encountered

I did a full database export using exp from a 10g Linux database:
Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - Prod

System:

    Version 2002
    Service Pack 3
Intel(R) Core(TM)2 CPU
6300 @ 1.86GHz
1.86 GHz, 3.25 GM or RAMI performed a full database import after creating the required tablespaces from the 10g database on Linux to Windows.
On the Windows 10g database, I set Maximum SGA size to 1300 MB, and Total SGA size to 1000 MB. I set Aggregate PGA Target to 500 MB.
This Windows box is going to be used by at most 2 developers for a change to our application that is not backward compatible (with respect to the database) with earlier versions of the application that uses the database. I was asked to create this so we could develop this branch without affecting the rest of the development team that are working on other enhancements on the Linux box.
I then ran some packages that refresh the data in a set of tables. This runs through some code that exercises a lot of the database so I could uncover any issues.
At a specific point in the execution of these packages I get the following error:
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [_qkkIsOJKey+299] [PC:0x1E58F73] [ADDR:0x80] [UNABLE_TO_READ] []I read the trace file and isolated it to a single, somewhat complex query. I tore the query apart into smaller queries, trying to isolate what was causing the issue. Whenever the core dump occurred, I was able to recover by simply closing the connection and opening a new connection. In my testing I found the specific query that raises the exception, and a less performing version of that query that does not cause the exception. Please note that this exception has never occurred on the Linux box (nor has it occurred on the beta or production database), and the code has been in place for close to 2 years.
The code that causes the issue:
SELECT UNIQUE
       oc.ogc_case_id AS oc_ogc_case_id,
       ogc.ogc_number AS ogc_number
FROM (SELECT SUBSTR (REPLACE (afd.field_text, '-', '' ), 1, 6 )    AS ogc_number
          FROM ewoc_hw_snap.activity_field_data afd
         WHERE afd.afdcd_activity_field_data_key = (SELECT afdc.activity_field_data_key
                                                      FROM ewoc_hw_snap.activity_field_data_codes afdc
                                                     WHERE afdc.name = 'Case Number'
       ) ogc
LEFT OUTER JOIN lct_snap.ogc_cases oc
        ON oc.ogc_number = ogc.ogc_numberThe code that returns the same data, only slower, and does not raise the exception:
SELECT UNIQUE
       (SELECT oc.ogc_case_id FROM lct_snap.ogc_cases oc WHERE oc.ogc_number = ogc.ogc_number ) AS oc_ogc_case_id,
       ogc.ogc_number AS ogc_number
FROM (SELECT SUBSTR (REPLACE (afd.field_text, '-', '' ), 1, 6 )    AS ogc_number
          FROM ewoc_hw_snap.activity_field_data afd
         WHERE afd.afdcd_activity_field_data_key = (SELECT afdc.activity_field_data_key
                                                      FROM ewoc_hw_snap.activity_field_data_codes afdc
                                                     WHERE afdc.name = 'Case Number'
       ) ogcI executed both queries in SQL Developer version 3.0.04. SQL Developer gives the error message: No more data to read from socket
Any ideas?
The query shown above is as simple as I could pare it down to and still raise and then fix the issue. The fix to the package is not as simple as the second query shown above since there is more than one column of data that I need to return from the lct_snap.ogc_cases table. In any case, I shouldn't have to forgo using the LEFT OUTER JOIN. There must be something wrong with the Windows database. I didn't want to patch the Windows database without first checking on this forum to see if anyone had any less intensive potential solutions.
I searched and found so many posts with the ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] error, that I realize it's a somewhat generic error message.

Have you logged a call with Oracle support? There are many causes of 7445's and oracle supports web site has a handy set of documents about them. Also they have:- : Troubleshoot an ORA-600 or ORA-7445 Error Using the Error Lookup Tool. I would highly recomend talking to them.

ORA-07445: exception encountered: core dump [hshget1()+199] [ACCESS_VIOLATION] [ADDR:0x18] [PC:0x8C4341F] [UNABLE_TO_READ] []

Hello all,
I am working on windows 64 bit (local system, testing)
Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
my database was working just fine, I was copying export dump(exp/imp) from 'A' hard disk(external) to 'B', as it was urgent I gave a table for import(imp) from 'A' hard disk which had the original dump.
import of table stopped with ORA-03113: end-of-file on communication channel
i thought it might be because I gave import when copy was going on, later on when copy was over I gave the same table for import, this time also I got same error.
when I tried to login as user "test" is gives me ORA 01033 error.
Enter user-name: test/test

To add more I was studying/practicing "Auditing in Oracle", yesterday System table space was getting full hence, exported "IDL_UB1$" and truncated it.
Please let me know if I need to provide any more information, also help me out to solve this issue.

Yes I have the backup of truncated table with me(I am practicing "auditing" in my local system hence exported the table and truncated the table as system table space was getting full.)
also i checked the trace file c:\app\administrator\diag\rdbms\prod\prod\incident\incdir_94924\prod_mmon_7848_i94924.trc, but not sure what to check..i mean it gives the same

not sure how to read this trace file,i mean how to find error part, kindly let me know on this.

ORA-07445 error in 10.2.0.4 database on Windows Server 2003

Hello,
We run an Oracle 10.2.0.4 database on a Windows 2003 Server. Yesterday we started encountering an odd, repeating error:
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [__VInfreq__kqlCompileSynonym+3038] [PC:0x2F93172] [ADDR:0x30] [UNABLE_TO_READ] []
I've tried researching this error on Metalink and Google, however I have not been able to find any information on the specific "VInfreq__kqlCompileSynonym" portion of the issue. I do not see any immediate issues with the existing synonyms in our database, so I am uncertain what else to check.
We've tried a database reboot, a server reboot, and checked the Event Viewer logs.... None of these things proved useful. :) Has anyone else experienced this issue? Any insight in to the specifics of this error?
Thanks!
-Sabrina

I'm assuming you logged a TAR about this on Metalink?
(sorry, an SR on Metalink)

ORA-07445: exception encountered: core dump [ldxsti+0208] [SIGSEGV] [Addres

Hi,
I am continuously getting this error in alert in my Production database.
Please suggest on how to get rid of this.

See ORA-7445 Troubleshooting
https://blogs.oracle.com/db/entry/ora-7445_troubleshooting
>
Have you observed an ORA-07445 error reported in your alert log?
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.

And see this advice from Oracle ACE Billy Verreynne
Re: ORA-07445: exception encountered: core dump
>
Refer to Metalink (now called My Oracle Support ) note id 310099.1 - it lists a whole bunch of 10r2 bugs related to the EVAOPN2 module.
Also, SOP for such errors is to log a SR (Service Request) with Oracle Support.

as Justin said its a tough position for you...
this case ...do you have proper backup of database before you mentioned error?
if you have database backup..download the oracle 11gR2 and install and upgrade it. i hope it may resolve your issue...
hope your AIX 6.1 OS also compatable for Oracle 11gR2...install 11gr2 on diff directory and upgrade it... remove 10g binaries
check below links..for installtion and upgrade
