Hi DBAs,
I was asked by one of my customer on the following situation:
Oracle instance was terminated due to problem in written to one of the redo
(the customer has mirrored redo files ) here is part of the alert :
Errors in file C:\ORACLE\diag\rdbms\ldb\ldb\trace\ldb_lgwr_4272.trc:
ORA-00345: redo log write error block 5 count 1
ORA-00312: online log 8 thread 1:
'E:\ORACLE\ORADATA\LDB\ONLINELOG\AXX_REDO02.LOG'
ORA-27070: async read/write failed
OSD-04016: Error queuing an asynchronous I/O request.
O/S-Error: (OS 23) Data error (cyclic redundancy check).
Errors in file C:\ORACLE\diag\rdbms\ldb\ldb\trace\ldb_lgwr_4272.trc
(incident=816098):
ORA-00600: internal error code, arguments: [kccocx_01], [kcrf.c], [10030],
[], [], [], [], [], [], [], [], []
Incident details in:
C:\ORACLE\diag\rdbms\ldb\ldb\incident\incdir_816098\ldb_lgwr_4272_i816098.trc
My customer asked me , why oracle db crashed , because the LGWR was able to
write correctly to one member (the one that didn't have i/o problem)
thans,
