10 I verified at database level whether the dump directory, its path and the proper read & write privileges are granted on the directory. Yes everything was fine at database end. I believed this could be an issue of nfs mount option at OS level. We are using an NFS shared mount point for all of the servers it needs to get mounted with proper options on each server to get it used by the database. I

could see this mount point is mounted properly with recommended options by Oracle. Then i checked the logs at OS level, then i found the issue is related to nfslock services. The nfslock service is not running on this database. this service helps the client to lock a file in the related NFS mount point on the server to create a file and make write operations. >cat messages | grep lockd Mar 8 04:03:31 demoserver kernel: lockd: cannot monitor 10.207.80.179 Mar 8 04:03:31 demoserver kernel: lockd: failed to monitor 10.207.80.179 Mar 8 04:20:27 demoserver kernel: lockd: cannot monitor 10.207.80.179 Mar 8 04:20:27 demoserver kernel: lockd: failed to monitor 10.207.80.179 Further i came to know that t the server got rebooted couple of days ago for a reason, after reboot the nfslock services did not startup automatically. So manually we started the services. Note that If the nfslock services need to get auto start after a reboot then we need to use chkconfig nfslock on. Later the same has been taken care. hence onwards whenever the server gets rebooted the nfslock services will automatically startup. cat messages | grep rpc Mar 8 07:01:43 demoserver rpc.statd[12667]: Version 1.0.9 Starting Mar 8 07:01:49 demoserver rpc.statd[12667]: Caught signal 15, un-registering and exiting.

ORA-27086 Tips Oracle Database Tips byLinux-x86_64 Error: 11: Resource Temporarily Unavailable
Burleson Consulting February 15, 2015 Question: I am running a job and I am getting this ORA-27086 error: ORA-27050: function ora-27086: unable to lock file - already in use netapp called with invalid FIB/IOV structure Additional information: 2 ORA-27086: unable to lock file - already in use Linux-x86_64 Error: 37: No locks available Additional information: 10 What is the cause of the ORA-27086 error? http://shafiulladba.blogspot.com/2014/03/nfs-locking-issue-while-data-pump.html Answer: The oerr utility shows this for the ORA-27086 error: ORA-27086: unable to lock file - already in use Cause: the file is locked by another process, indicating that it is currently in use by a database instance. Action: determine which database instance legitimately owns this file. This is not an Oracle error, it has an external cause an you will want to contact your OS systems http://www.dba-oracle.com/t_ora_27086_unable_to_lock_file.htm administrator. See MOSC Note 1418233.1 titled "Archiving Redo Logs Fails With ORA-19510, ORA-27086 Linux-x86_64 Error: 37: No locks available" 1. As an emergency workaround, this error can usually be remedied by re-booting the server. 2. In Linux and AIX you can fix the error by changing /etc/filesystems. In Linux, the option line, using nolock instead of llock -- LINUX# cat /etc/filesystems. . . option=nolock 3. The ORA-27086 error can also happen when NFS is hung. You can check your OS logs to find "statd: server localhost not responding, timed out".4. Check rpc.stat is working and you can restart again , and you have to Restart NFS Services. Here is how to bounce NFS: /etc/init.d/nfs restart You can also bounce NFS by each service: # service nfslock stop# service nfs stop# service portmap stop# umount /proc/fs/nfsd Start :# service portmap start# service nfs start # service nfslock start# mount -t nfsd nfsd /proc/fs/nfsd Get the Complete Oracle SQL Tuning Information The landmark book "Advanced Oracle SQL Tuning The Definitive Reference" is filled with valuable information on Oracle SQL Tuning.

FredC May 5, 2008 8:34 PM My 10.2 database crashed, and when it came back I got the following error: ORA-00202: control file: '/local/opt/oracle/product/10.2.0/dbs/lkFOOBAR' ORA-27086: unable to lock file - already in use Linux-x86_64 Error: 11: Resource temporarily unavailable This is a classic symptom of a Netapp problem, which likes unable to lock to hold file locks open on NFS mounts. There is a standard procedure for clearing those locks; see, for instance, document 429912.1 on Metalink. Unfortunately, my files are mounted on an Isilon, one of Netapp's twisted cousins. I can find no references to "isilon" on Metalink, and we are at a loss how to resolve this. My sysadmin assures me that "there are no locks on the Isilon". But I know this cannot be the case, because if I do the following: 1. delete the lockfile /local/opt/oracle/product/10.2.0/dbs/lkFOOBAR, and then 2. move my controlfiles aside, and then copy them back into place, then the database will mount. However, it will not open, because now all the datafiles have locks. Is there anyone with experience in clearing NFS locks? I know this is more of a SA task than DBA, but I am sure my SA has overlooked something.

NFS : Resolving "ORA-27086: unable to lock file - already in use" Error By Giri Mandalika-Oracle on Oct 10, 2011 Some Context Oracle database was hosted on ZFS Storage Appliance (NAS). The database files are accessible from the database server node via NFS mounted filesystems. Solaris 10 is the operating system on DB node. Someone forgets to shutdown the database instance and unmount the remote filesystems before rebooting the database server node. After the system boots up, Oracle RDBMS fails to bring up the database due to locked-out data files. eg., SQL> startup ORACLE instance started.

Reason for the lock failure: Because of the sudden ungraceful shutdown of the database, file locks on data files were not released by the NFS server (ZFS SA in this case). NFS server held on to the file locks even after the NFS client (DB server node in this example) was restarted. Due to this
