By querying metalink id: 387700.1

The document says that there are several possible problems:

A) The mount table (eg; / etc/mnttab) can be read to check the mount options

B) The NFS mount is mounted with the "hard" option

C) The mount options include rsize > = 32768 and wsize > = 32768

D) For RAC environments, where NFS disks are supported, the "noac" mount option is used.

The documentation indicates that it can be avoided by setting the event 10298 event, but setting event 10298 requires a database restart to take effect.

Check the configuration of NFS and find that there is no entry for mount nfs file system in / etc/filesystems of the client.

After adding the following entry, re-mount, solve.

# vi / etc/filesystems

/ exp:

Dev = / exp

Vfs = nfs

Nodename = 192.168.1.20

Mount = true

Options = rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=600

Account = false

# umount / oraexp

# mount / oraexp

It is recommended that you encounter similar problems in the future, first check the / etc/filesystems file, this problem is caused by everyone likes to use the following way mount nfs.

LINUX uses the following methods:

Mount-o rw,bg,hard,intr,proto=tcp,vers=3,rsize=65536,wsize=65536,timeo=600 192.168.1.20:/exp / exp

Aix uses the following methods:

Mount-o hard,bg,proto=tcp,suid,rsize=32768,wsize=32768,noac 192.168.1.20:/backup / backup

Aix reference articles

RMAN Backup Fails With RMAN-03009 ORA-19504 ORA-27054 NFS file system where the file is created or resides is not mounted with correct options [ID 1472448.1]

ORA-27054: NFS file system where the file is created or resides is not mounted with correct options [ID 781349.1]

/ / the process of setting another 10298 is as follows:

1) set the Event 10298 in the init file

Event= "10298 trace name context forever, level 32"

If you are using the spfile then the following can be done

SQL > alter system set event='10298 trace name context forever, level 32 scope= spfile
