this problem urgent please help me.
Unfortunately, ORA-07445 errors are better solved with the aid of Metalink and Oracle support. You can post your contents of the trace file that was generated, mainly the stack trace, to see if some would look up the error for you. The problem though is if the only fix/workaround for your problem is in the form of a patch. If that is the case, anyone that provides the patch will be in breach of their support contract.

ORA-07445: core dump in kkogbro()+192

Dear all,
when issuing a view query through a web browser (oracle forms) the remote client receives ora-3113, at the same time alert.log shows:
ORA-07445: exception encountered: core dump [kkogbro()+192] [SIGSEGV] [Address not mapped to object] [0x000000000].
These are the details of the environment:
Oracle Database 10g Release 10.2.0.1.0 - 64bit Production
With the Real Application Clusters option
System name:     Linux

Version:     #1 SMP Wed May 2 15:06:32 PDT 2007

Is this an oracle bug or can it be solved?
Thank you very much for any help!
Kind regards!

Oracle Support takes a lot of timeI recently raised a couple of SR, and honestly, the support was rather responsive. Be sure you logged the SR in the proper category, with proper priority, and all the information they would need to work on.

3. Make sure Swap is correctly configured and increase it if necessary.--Could you please tell me how to set the Swap configured.
4. Raise SR with Oracle Support.--Raised, apply the patch, the error still happened.

I got this error and i raised a SR in metalink, and metalink suggest to make
"_complex_view_merging" = false, but its already set to false.
So what to do for this resolution of this error.
Internal error :

When you already have an open SR, you should ask Oracle support for further assistance.

Gateway for Sybase - core dump [npixfc()+243] [SIGSEGV]

Hi All,
We are using a couple of gateways to various Sybase servers in our environment, which generally work very fine.
However, occasionally we find the following lines in the alert.log on one or the other node of the cluster.
The DB platform is currently 11.2.0.1 in RAC on Linux x86-64 RHEL5, but similar problems happened
before on 11.1.0.7 (the entries in the logs were not as descriptive as on 11gR2).

Thanks for your reply. I expected the advice to utilize the support for that :)
The results of my investigation:
Listener log - normal activity. New connections to the DB and to different gateways (including the one that caused the problem) every couple of seconds, everything seemed to be working fine.
Alert log - no other entries +/- 1 hour around the incident, except log switching.
I checked the application logs and managed to find out the session that caused the problem. It is an ETL process that runs the same extraction query on Sybase machine every minute. The query does not change and it was executed successfully hundreds of times before. Other similar processes were running fine, executing similar queries on all Sybase machines, including the one in the incident. So the incident seems to be random, with no correlation to other activities.
The flow of events in the problematic session iis as follows:
1. opens Gateway connection and sets session parameters on Sybase by executing:
dbms_hs_passthrough.execute_immediate@PM04PMDB('set lock wait 60 ') -> that went OK
2. starts data extraction by running:
insert into ... select ... from ...@PM04PMDB -> that operation hang, no further logs from this point
3. commits
4. closes DB link by executing:
alter session close database link PM04PMDB
The SQL that failed was executed at 7:23, and the incident entry in the alert log is dated 7:33.
Is it possible that the 10 seconds delay is caused by HS_FDS_CONNECT_PROPERTIES="timeout='10'" ?
The gateway config:
HS_FDS_CONNECT_INFO=xxx
HS_FDS_TRANSACTION_MODEL=READ_ONLY
HS_FDS_TRACE_LEVEL=OFF
HS_OPEN_CURSORS=10
HS_FDS_CONNECT_PROPERTIES="timeout='10'"

Please suggest on how to get rid of this.

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

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.

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.

Reply from nagulan is correct. Our turned out to be an error with TSM. The disk pool had filled up and it was writing this to tape before allowing the backup to continue. The backup didn't handle the "pause" event well and failed out. We only get this with V9 RMAN, not V10 or V11 RMAN backups. This has to be addressed by the backup vendor for V9 as the Oracle RMAN software doesn't seem to handle it well. Maybe configuring a really large timeout for responses MAY fix this, depending on what the code returned from the backup software vendor is and why RMAN isn't happy with it.
In the end it is an issue between V9 RMAN and the backup software we run TSM. Maybe version incompatibility or maybe just V9 is not that robust.
