Bug 10422126 : FAILED TO READ MORROR SIDE 1	转到底部

Hdr: 10422126 11.2.0.1 RDBMS 11.2.0.1 ASM PRODID-5 PORTID-212
Abstract: FAILED TO READ MORROR SIDE 1
 
*** 12/22/10 03:46 am ***
----
 
PROBLEM:
--------
Alert log spooling this error continously and filling up available space.
Here is the message.
-----------------------
WARNING: failed to read mirror side 1 of virtual extent 665 logical extent 0 
of file 280 in group [1.445758315] from disk ASM_ESBQA001_DATA1_0005 
allocation unit 75811 reason error; if possible,will try another mirror side
-----------------------
 
When the problem starts, errors spin in the alert log until disk space is 
exausted. We have found that the process that is refrenced in the trace is 
usually an orphaned ebiz form.
 
Recent Changes - Upgrade to 11.2.0.1
 
Over the weekend we have upgraded Production Database to 11.2.0.1. We've had 
2 occurrence of the issue on 2 of the RAC nodes.
 
The issue had happened in QA and we have tried to drop the disk and add new 
disk again, but it did not solve the problem.
 
One more thing to note is, when this happens, there was a "run-away" process 
that also generates the same error message in a trace file. As long as that 
session/process is killed, the error messages stops. Please investigate.
 
DIAGNOSTIC ANALYSIS:
--------------------
This looks closely related to bug.10051315 and bug.10055063
But customer has applied these patches already, even then we still see the 
same warning messages.
 
We are still trying to get information from customer to understand how that 
session is being killed(not sure could be from database end --or application 
end).
 
Customer confirmed the following :
---------------
1.) Are they in-house scripts scheduled in database/os which are going to 
kill the inactive sessions at database/os level ?
-- There are not any scripts scheduled to kill sessions. When this error 
starts happening, we kill the process manually.
 
2.) Is this happening only during specific intervals.
-- I cannot see a pattern as to when it is happening. It seems random.
 
3.) Please confirm - the ASM instance is functional (one can connect to it, 
run queries on the various v$asm% views, like: v$asm_diskgroup, v$asm_disk)
-- Yes, ASM is functional during the error. All other sessions continue to 
run without errors.
---------------
 
WORKAROUND:
-----------
As long as that session/process is killed, the error messages stops.
 
RELATED BUGS:
-------------
