Problem IC84264
|
Status: Geschlossen |
ESTALE FROM READ() OR WRITE() SYSTEM CALL COULD CAUSE LOSS OF DB2AUDIT RECORD |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problembeschreibung: |
db2audit archive option will rename/copy/delete the existing
audit log files.
If the audit log files are on NFS, deleting of audit log files
from NFS server may not notify all NFS clients
on time, so some NFS clients may receive ESTALE error message
from read() or write() system call, after the file is reopened.
A typical db2diag.log message may look like following:
PID : 407004 TID : 1 PROC : db2bp
INSTANCE: db2inst1 NODE : 025
EDUID : 1
FUNCTION: DB2 UDB, oper system services, sqloread, probe:60
MESSAGE : ZRC=0x860F0003=-2045837309=SQLO_DERR "disk error
occurred (DOS)"
DIA8402C A disk error has occurred.
CALLED : OS, -, read
OSERR : ESTALE (52) "Missing file or filesystem"
DATA #1 : File handle, PD_TYPE_SQO_FILE_HDL, 8 bytes
File Handle = 4
File System Block Size = 0 bytes
File System Type = UNKNOWN
File Handle Flags :
Require Sector Align = No
Once db2audit receive ESTALE, it will tolerate the error but
this will cause loss of audit record.
This APAR allows db2audit to reopen the file and rewrite the
audit record once it receives ESTALE error message from system
calls.
Note that users may still see ESTALE errors in db2diag.log. It
is recommended to use local file systems for audit log files. |
