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 ksedmp: internal or fatal error ORA-07445 (See ORA-07445.ora-code.com): exception encountered: core dump [0000000101375D20] [SIGSEGV] [Address not mapped to object] [0x000000020] [] [] Current SQL statement for this session: SELECT COUNT(*) FROM (SELECT PRIVILEGE FROM USER_SYS_PRIVS WHERE PRIVILEGE = 'CREATE USER' UNION ALL SELECT PRIVILEGE FROM ROLE_SYS_PRIVS WHERE PRIVILEGE = 'CREATE USER')
Doc ID: Note:278302.1 Subject: ORA-07445 (See ORA-07445.ora-code.com) OCCURS DURING SHUTDOWN OPERATION IN FUNCTIONS KPOGUP OR LMXSPAX Type: PROBLEM Status: PUBLISHED Content Type: TEXT/X-HTML Creation Date: 13-JUL-2004 Last Revision Date: 20-AUG-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:-
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
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.
