Hi Wolfgang,
be sure to set the right mount options for NFS:
Mount Optionen f?r Datenbankdateien auf NFS
SINGLE INSTANCE:
-- ---- ---- ---
SLES9 , RHEL4 , RHEL3:
rw,bg,hard,nointr,tcp,vers=3,timeo`0,rsize2768,wsize2768
RHAS2.1:
rw,bg,hard,nointr,tcp,vers=3,timeo`0,rsize2768,wsize2768
In /etc/modules.conf add:
options nfs nfs_uncached_io=1 NOTE: Only set this for AS 2.1
RAC INSTANCES:
-- ---- ------
SLES9, RHEL4, RHEL3 QU3 and later:
rw,bg,hard,nointr,tcp,vers=3,timeo`0,rsize2768,wsize2768,actimeo=0
RHAS2.1, RHEL3 pre QU3:
rw,bg,hard,nointr,tcp,vers=3,timeo`0,rsize2768,wsize2768,noac
And for AS 2.1 in /etc/modules.conf add:
options nfs nfs_uncached_io=1 NOTE: Only set this for AS 2.1
Regards
Oliver

Betreff: [suse-oracle] Oracle-datafiles on NFS-Volume
Hello,
I want to install an Oracle 9i - instance on a NFS-mounted Volume.
The NFS-volume is on a SLES8-NFS-server, our Oracle is installed on another
SLES8.
SLES8 uses Linux version 2.4.21-278-default,
The NFS-mount works fine, using the NFS-share for files works.
But during creation an Oracle-instance with dbca I got various errors like ORA
-27086 and others.
I also got errors after moving an existing instance to a NFS-share. I cannot
start the
instance because Oracle complains some locking errors.
Searching through Metalink gave me some information about Direct-IO on NFS, but
I cannot get it working.
Does anyone use such a structure?
|-- ------| |-- ---- ---- ---- ---- ---- -----|
| DB-HOST |----NFS via TCP/IP----| NFS-Server with Oracle datafiles|
|-- ------| |-- ---- ---- ---- ---- ---- -----|
Thank you
Wolfgang Wagner
