Re: nfs error while installing oracle

hi,

check whether all ur nfs service is running ok

ps -aef|grep nfs.

check whether pfs_mountd is running are got killed.


when the problem araises once after starting the gui are while running the command itself.

if u have any other cd check with that.

Re: nfs error while installing oracle

Hi ,
You might want to add this to your fstab :
/dev/dsk/c0t1d0 /SD_CDROM pfs-rrip xlat=unix 1 0

Next do 2,3,4 as mention in your post.

Re: nfs error while installing oracle

Here is the procedure for mounting a
Rockridge CD

Add this entry to /etc/pfs_fstab

/dev/dsk/c5t2d0 /SD_CDROM pfs-rrip xlat=unix 10

Mount the cd in the drive

# nohup /usr/sbin/pfs_mountd &
# nohup /usr/sbin/pfsd &
# /usr/sbin/pfs_mount /SD_CDROM

Make sure the directory is created and you
have not got your shell in that directory at
the time of mounting.

Please note, that if you have the latest patches, you should be able to just mount the CD.

Make sure that you have enough 'nfsd' deamons running to service all requirements.

Regards

Re: nfs error while installing oracle

hi,

one another check the patch dependices.i think there are some nfs patches are there of hpux 11.0.

if u are using dns for name resolution check it out.

if not check ur /etc/hosts file.
if u have nis or nisplus for resolution then do check in that.

if u have nfs server mount it from another server and try to install it.

nfs patch

Re: nfs error while installing oracle

For educational purposes, I'm going to try and explain why the error happened the way it did.

Oracle uses Rock ridge format on their cd's.

to mount them, as you know you have to use pfs_mount

pfs_mount seems to depend on certain nfs services in order to function.

If you ever get really hung in an oracle install you can get out of it like this.

fuser -cuk /SD_CDROM

That will wipe out all the processes on the filesystem.

The important rule of thumb with oracle is never do the old

cd /SD_CDROM

trick when doing an install. When Oracle asks for disk 2 you are screwed, because there is an open process on the filesystem and you can't unmount ANY filesystem with an open fs on it.

So you do the pfs_mount as you know how and then as oracle user...

/SD_CDROM/runInstaller &

Then pfs_umount will actually work when you are ready to change cd's.

I hit this error several times, and never solved it with nfs patches.

Perhaps they solved it because they required a reboot.

No points necessary, just though you'd like to know how and why oracle messed with your life today.

Re: nfs error while installing oracle

hi steve,

thats was really nice explanation.
but we are oracle installation via a script which does not do cd
/SD_CDROM

it calls orainstaller as u mentioned.

as it was a testing server we had rebooted many times.but doesn't solve the problem.

HP's explaned it . pfs does depend upon some nfs services.
which was causing the hang in pfs
so it was giving this error.

but really ur answer was good one.

Re: nfs error while installing oracle

Hi unix_admin,

I am getting the same problem -
# /usr/sbin/pfs_mount /SD_CDROM
/usr/sbin/pfs_mount: /dev/dsk/c2t1d0 on /SD_CDROM: not rrip.
/usr/sbin/pfs_mount: giving up on /SD_CDROM

Could you please tell me the patch name sothat i can download them or tell me link for the same.

Thanks & Regards
