Hi...!!!
Error - 7445 and the description on Metalink.
I have got another arguments then the described in the document. I opened
an iTAR with previous employer and
oracle said this is not gonna corrupt yr database. Neither at physical or
logical level.
Is the arguments really matters? The query given with this is very simple
select query.
Any idea ??? I don have much idea about the arguements but know that it
says abt the kind of operation you were doing like.
Regards - Chirag

Type: PROBLEM
Status: PUBLISHED
Content Type: TEXT/X-HTML
Creation Date: 13-JUL-2004

The information in this article applies to:
Oracle Server - Enterprise Edition - Version: 8.1.7.4 <http://8.1.7.4> to
9.2.0.7 <http://9.2.0.7>
This problem can occur on any platform.
Errors
The following errors have all been observed for the this issue:-
ORA-07445 (See ORA-07445.ora-code.com)[KPOGUP]
ORA-07445 (See ORA-07445.ora-code.com)[LXMSPAX]
ORA-07445 (See ORA-07445.ora-code.com)[SIGSEGV] [ADDRESS NOT MAPPED TO OBJECT]
Symptoms
All of the following symptoms will be observed
a) The failing functions KPOGUP or LXMSPAX will be reported in the 7445
error and the function KPOGUP will be reported in the stack trace OR (b)
b) The failing function KPOGUP will be reported in the stack trace and the
7445 error will contain SIGSEGV
c) The ORA-07445 (See ORA-07445.ora-code.com) will be reported after a SHUTDOWN IMMEDIATE operation.
d) The current SQL session will report : Current SQL information unavailable
- no session.
e) Crash/Media recovery is not affected on startup
The stack will be similar to:-
sigacthandler kpogup kpofli kpolon opiodr ttcpip opitsk opiino opiodr opidrv
sou2o main start
OR
ksedmp ssexhd sigacthandler lxmspax kpogup kpofli kpolon opiodr ttcpip
opitsk
opiino opiodr opidrv sou2o main start
The key function that needs to be present in the stack trace is KPOGUP
Cause
The root cause of the problem relates to which addresses an issue in
accessing
NLS object list information during SHUTDOWN IMMEDIATE. There is no impact to
the database
other than a 7445 trace file taking space on disk.
Fix
The fix is provided in Oracle10g but due to the architectural changes
required is not backportable to earlier releases. There is no recommended
workaround for this error as it has no impact to the database and no known
set of circumstances that avoid/cause it.
