This ORA-27086 , ORA-31641, ORA-39000 errors are related with the NFS Lock Service or NFS Mount permissions.

 

Firstly Check NFSLock service like following.

# service nfslock status

rpc.statd is stopped
If it is not started, then start it as follows.
# /etc/init.d/nfslock start
Starting NFS statd:                      [ OK ]

 

And run the following command to start nfslock service automatically when the server reboot.

# chkconfig nfslock on

 

Other case; On Oracle Linux, when making use of NFS and an Oracle Database, the database may report :

ORA-27086: unable to lock file - already in use
Linux-x86_64 Error: 37: No locks available

 

Bug in nfs-utils package

Bug 8727960 : LX64: DATAFILES ON NFS, ORA-01157: CANNOT IDENTIFY/LOCK DATA FILE 202 (unpublished Bug) 

 

To solve this error,  Upgrade to nfs-utils-1.0.9-66 or later
