ORA-03113/ORA-07445 on startup.. it ate my baceba11

After shutting down a machine and rebooting it, oracle starts no longer.
Looks to be a segfault in skgmidrealm.
Anyone seen this? I'm kind of out of ideas as far as how to resolve it.
Crashing seems to leave behind some shm and sem, sqlplus dies with
ORA-01041: internal error. hostdef extension doesn't exist
until I kill them off with ipcrm, at which point I can try again to connect, but
get the same segfault and resulting behavior.

hmmmmmm, are u sure that u get all the OS patch and/or packages for your Oracle version ?
That sounds strange. I got quite the same problem when relinking an Oracle 9i R2 on AIX5L and an OS package was missing but was NOT in the pre-requisite documentation...
Good luck,
Fred

ther is a lot of reasons for this issue I suggest that you try to do some action to try to understand where is the problem:
1. Change the connection string to contain only the schema parameter (no pooling parameters).
2. Change the select to return only 1:
_SELECT 1 as val_
FROM IIL_RUN_SETS ILRS
INNER JOIN IIL_RN_SET_STA_VALS ISSV
ON ILRS.ILRS_ID = ISSV.ILRS_ID
AND CURRENT_TIMESTAMP BETWEEN ISSV.TRANS_FROM AND ISSV.TRANS_TO
INNER JOIN IIL_RN_SET_STATUSES ISST
ON ISSV.ISST_ID = ISST.ISST_ID
INNER JOIN IIL_RUNS ILRN
ON ILRS.ILRS_ID = ILRN.ILRS_ID
LEFT OUTER JOIN IIL_RUN_LABELS IRLB
ON ILRN.IRLB_ID = IRLB.IRLB_ID
INNER JOIN IIL_RUN_STA_VALS IRSV
ON ILRN.ILRN_ID = IRSV.ILRN_ID
AND CURRENT_TIMESTAMP BETWEEN IRSV.TRANS_FROM AND IRSV.TRANS_TO
INNER JOIN IIL_RUN_STATUSES IRST

INNER JOIN USERS UPDATE_USER
ON ILRN.UPDATE_USER_ID = UPDATE_USER.USER_ID
WHERE ILRS.ILRS_ID ; = :B1
_AND rownum=1_
ORDER BY ILRN.ILRN_ID
if this result will not return the value that means that the problem is in the SQL/Procedure
3. Try to run on diffrent client - it maybe related to some ODP problem one one client.

8i intermedia ORA-03113 ORA-07445 CTX$N

We get the occasional ORA-03113 end of file communication error along with a trace file with ORA-07445. On looking at the CTX$N - described as the negative list table I found it had quite a few entries (nearly 10,000). When I rebuilt the index the problem went away and the CTX$N table was empty. Clearly it gets written to during the course of time. Does anyone know any details or have any suggestions as to if/when large numbers of entries might cause this sort of failure.

In the last couple of days we have started seeing ORA-03113 on some interMedia queries that lead me to think we're running into bug 1517789 (8.1.7.0.0 on NT4WSSP6a). The bug is supposed to be taken care of in the 8.1.7.1b patchset, but I haven't yet found the patch for NT. Does anybody have more information or a link to the patch?
Interestingly, the number of rows in the table (in the hundreds), rows in the DR$ tables (a few thousand), and number of hits (hundreds) are small. It does respond to the "well, don't do that" workarounds mentioned in the bug discussion, though--changing the contains from '%' to a couple of characters preceeding the '%'.
Any information appreciated

ORA-07445 on Ubuntu 8.04

Hello,
I manage Oracle Database 10g Express Edition Release 10.2.0.1.0 on a Linux Ubuntu 8.04 server for some students.
I've installed the package oracle-xe-universal
Simple queries works fine but some like this one does'nt work :
SQL> 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');
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

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!

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.

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.

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
"ORA-07445: exception encountered: core dump [hshget1()+199] [ACCESS_VIOLATION] [ADDR:0x18] [PC:0x8C4341F] [UNABLE_TO_READ] []" error at the start
not sure how to read this trace file,i mean how to find error part, kindly let me know on this.

Met ora-07445 on oracle 10.2.0.4 of Windows 2003

Hello,
I was running an PL/SQL application using PL/SQL Developer and after a while, the application will be disconnected from the database with error 03113: end-of-file on communication channel. I checked the alert.log file of the database, at that time an ora-07445 error happened:
Errors in file c:\oracle\product\10.2.0\admin\dbtest1\udump\dbtest1_ora_4820.trc:
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [unable_to_trans_pc] [PC:0x0] [ADDR:0x0] [UNABLE_TO_READ] []
My environment is oracle 10.2.0.4 on Microsoft Windows 2003(32bit).
My friends helped me search on metalink about this error and didn't find a similiar workaround. Can anybody take a look at this error or give some hint?
I want to upload the trace file but didn't find the entry to upload a file. Please let me know if I need to paste all the content of the trace file. it is too long.
Thank you very much.
Tony

I hope that I can log a SR because the metalink account is in our dba hands and till now, almost one month passed we got no answer form him.tough situation - Mystery Problem that you can't deal with directly, having to work through the powers that be second-hand to get support. Been there, done that :(
You probably haven't heard from the DBA because the DBA hasn't heard anything back from MOS - a pure guess on my part, but according to my experience in logging SRs quite possible.
You have some options - not good ones but they do exist. The ideas below are different variations based on the idea that if you can figure out where the program is having trouble you might be able to work around the problem.
There is no trace in PL/SQL as such, but there is a debugger. I'm not sure if you are using All-around Automations's PL/SQL developer or Oracle's SQL*Developer but both support the debugger. You can compile stored code in debug mode and use a GUI interface in both products (TOAD too, for that matter) to set stopping points to monitor your progress. There is information about the debugger in the Oracle documentation and elsewhere on-line. IF YOU CHOOSE TO USE THE DEBUGGER USE A GUI INTERFACE TO SET IT UP AND RUN IT - the command-line interface via PL/SQL APIs in SQL*PLUS is nearly impossible to use effectively.
Alternately and more easily you can put your own markers in the code and execute it. This can take the form of lines like DBMS_OUTPUT.PUT_LINE('Got to line 999') or more elegantly using dbms_application_info to set a column value in V$SESSION to put a message there (procedure name, line number, whatever you want within reason). You'll only see DBMS_OUTPUT.PUT_LINE data after the program(s) finish or crash so the dbms_application_info method might be a little bit more useful
Good Luck!

ORA-07445 and ORA-01331end-of-file on communication channel

Hi,
: Can any one help?
: We have an oracle server 8.1.7 on Solaris 8 sparc station.

Yes i am connecting through client side(TOAD).
When i continously execute the query then there is no problem. But problem occurs when i sits idle more than approx. 2 minutes.
Listner is properly running at server side.
Also while connecting though toad
1st Error is

Ora-12541: TNS: No Listener
Then it connects.
What is the problem?
Where i can look into?
Thanks,

I need help with ORA-07445

Hi all!
I was executing every day one workflow which contains some mappings. This worked fine but one day it started crashing. The error I get is:
ERROR ORA-03113: end-of-file on communication channel
We traced the session and we saw that it also produced this error:
ORA-07445: exception encountered: core dump [slmecpy()+96] [SIGSEGV] [Address not mapped to object] [0x000000000] [] []
Does anyone know what can be happening??
Thanks in advance
Edited by: Julius84 on 18-may-2010 3:55

Thanks, but I had tried doing it. I had regenerated the mapping and it doesn´t work.
I have read in internet that it's a bug, but i don't understand: i haven't changed anything.
Thanks again

Sudden ORA-01331 / ORA-07445 on aggregate count(*)?

Hi I've been running 10.2.0.1.0 successfully for a while.
One day both my development and my production system started locking up (timing out) in forms. I narrowed it down to a count query.
select count(*) from TABLE where
STATUS in (0, 2, 3, 4, 5, 7, 10)
in sqlplus gives me an ORA-03113 and an alert log with
Fri Apr 04 08:28:24 2008
Errors in file c:\oraclexe\app\oracle\admin\xe\udump\xe_ora_5252.trc:
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [_evaopn2+154] [PC:0x1BEDD4A] [ADDR:0x0] [UNABLE_TO_READ] []
The strange thing is running the query returns the correct rows when not using a count(*)
select * from TABLE where
STATUS in (0, 2, 3, 4, 5, 7, 10)
It was one of those overnight, no apparent reason errors. Can anyone help me or is there an update I should be installing?
Thanks

FYI I managed to find one of the fields that works. count(<NUMBER>) works. It didn't work to count(*), count(<INT>), or count(<VARCHAR>). Strange. Results are mixed with nullable/not nullable fields as well.
Anyway, found my solution.
Thanks
