ORA-07445 on Xen RHEL5.4 guest on Itanium Montecito (BL870c/BL860c) host

I am wandering if anyone had any experience with similar issue - it most likely related to something about Oracle on RHEL5.4 Xen host on an Itanium (Montecito core, to be specific, as this proved to make important difference - HP BL870c and BL860c servers). I didn't test this on same physical machine (Itanium/RHEL5.4). I am running Oracle 10.2.0.4 with CPUJul2009 (patch 19) and all the latest OS RHEL5.4 updates, and ECC6.0 on top. It works very good, but Oracle is getting ORA-07445 (evabtr) from time to time, which causes ORA-03113 (disconnect session) on the ABAP side (or whatever is connected to db, eg. imp or impdp, too) - something like SGEN can cause it (anything making load long enough). I did everything by the book, with all SAP recommendations and I was hopping I am was doing something wrong. Anyone ?

Ok, you asked for it (IASDB database instance was just a DBCA general template created database, and this alert log is it's very first bringing up after creation, no special load applied even):

ORA-07445 on Xen RHEL5.4 guest on Itanium Montecito (BL870c/BL860c) ho

I am wandering if anyone had any experience with similar issue - it most likely related to something about Oracle on RHEL5.4 Xen host on an Itanium (Montecito core, to be specific, as this proved to make important difference - HP BL870c and BL860c servers). I didn't test this on same physical machine (Itanium/RHEL5.4). I am running Oracle 10.2.0.4 with CPUJul2009 (patch 19) and all the latest OS RHEL5.4 updates, and ECC6.0 on top. It works very good, but Oracle is getting ORA-07445 (evabtr) from time to time, which causes ORA-03113 (disconnect session) on the ABAP side (or whatever is connected to db, eg. imp or impdp, too) - something like SGEN can cause it (anything making load long enough). Similar thing happens on Windows guests, too. I did everything by the book, with all SAP recommendations and I was hopping I am was doing something wrong. Anyone ?
Zoran.

Xen for Itanium (IA64) is not a supported virtualization platform. I doubt any testing has been done on that platform.

select nomf, nomp, prixp from ( commande co join client c on co.numc=c.numc ) join (produit p join fournisseur f on p.numf=f.numf ) on p.nomp=co.nomp where ( nomc = 'Jean')
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Then, if I try any other querie I have the following error :
ERROR:
ORA-03114: not connected to ORACLE
Here is what it gives on alert_XE.log :
Fri Feb 12 10:35:43 2010
Errors in file /usr/lib/oracle/xe/app/oracle/admin/XE/udump/xe_ora_25191.trc:
ORA-07445: exception encountered: core dump [koksspac()+211] [SIGSEGV] [Address not mapped to object] [0x48] [] []
Can somebody help me ?

I don't agree that the result (ora-7445, which is in fact an internal error) should occur in any circumstances.
but, the platform isn't supported. so you don't have anywhere to go but to rewrite the sql and see if that works.
if your question is answered, please mark the question as answered!

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?

ORA-07445 (solaris 9.0.) when inserting into LONG column

i am getting a core-dump when inserting into a table w/ long column. running 9.0.1 on solaris.
ORA-07445: exception encountered: core dump [kghtshrt()+68] [SIGSEGV] [Address not mapped to object] [0x387BBF0] [] []
if anyone has ANY input - please provide it ... i am desperate at this point.
i am trying to avoid upgrading to 9.2.0 to solve this problem.
regards -
jerome

You should report this in a service request on http://metalink.oracle.com.
It is a shame that you put all the effort here to describe your problem, but on the other hand you can now also copy & paste the question to Oracle Support.
Because you are using 10.2.0.3; I am guessing that you have a valid service contract...

ORA-07445 in the alert log when inserting into table with XMLType column

I'm trying to insert an xml-document into a table with a schema-based XMLType column. When I try to insert a row (using plsql-developer) - oracle is busy for a few seconds and then the connection to oracle is lost.
Below you''ll find the following to recreate the problem:
a) contents from the alert log
b) create script for the table
c) the before-insert trigger
d) the xml-schema
e) code for registering the schema
f) the test program
g) platform information

You should report this in a service request on http://metalink.oracle.com.
It is a shame that you put all the effort here to describe your problem, but on the other hand you can now also copy & paste the question to Oracle Support.
Because you are using 10.2.0.3; I am guessing that you have a valid service contract...

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:
    Microsoft Windows XP
    Professional
    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.

11.1.0.7: got ORA-07445 [qesmaGetTblSeg_INT()] errors; no help in MetaLink

A string of ORA-07445 [qesmaGetTblSeg_INT()] and [qesmaGetIdxSeg_INT()] errors were raised in DB 11.1.0.7 Enterprise Edition (64-bit) on Windows Server 2003 R2 Standard x64 Edition, SP2. A check of MetaLink and other search engines turned up no related references. These errors appeared in trace when the database became unresponsive, and again, briefly, about 5-10 minutes after I shut down the database and restarted the server. Would someone kindly suggest a source of useful information about these errors and possible corrective action(s)?
Thank you,
Bill

I may yet create an SR, but for now I am seeking information elsewhere. The system is in production. It is functioning normally at this time.

ORA-07445: exception encountered

once db is restarted and service is restarted everything works fine again after 3 to 4 hours database refused to establish new connections.
its a mission critical database hosted on windows server 2003 enterprise edition 32 bit. 4G RAM and 14G virtual

Hi,
Problem had a work around flushing shared pool after every 5 hrs. Permanent solution was adding 2 GB ram to server and application of patch 10.2.0.4
after patch application problem has completely resolved and there has not reoccured.

Hi All,
finally have some sort of answer from the other forum - Oracle Database 10g Express.
See subject - "Universal edition choke on en-GB browser, core dumped, ORA-07445"
Looks like a long standing bug and the suggested work around from the guys there is to change the browser language to en-us. I was using en-au and the author of the thread was using en-gb - both cause a core dump. Don't know how they figured it out.

ksedmp: Obtaining call stack failed twice. not retrying

check the arguments for ORA-7445 errors.
7445 errors are internal you need to contact oracle support, and also for work around you can pass those arguments in *Troubleshoot an ORA-600 or ORA-7445 Error Using the Error Lookup Tool [ID 7445.1]*
due to 7445 erros database was hung up/not responeded, so may be it is the reason for 3113 errors(inbound connection timeout)
and post the value of sqlnet_authentication_services from sqlnet.ora file..
Thanks
