Direct NFS: please check that oradism is setuid --> Enable/ Disable oradism ORADISM

Direct NFS: please check that oradism is setuid

 Issue:
Getting the following message in alert log and instance not starting:
Direct NFS: please check that oradism is setuid

To correct, the following permissions are needed on:
ls -la $ORACLE_HOME/bin/oradism
-rwsr-x— 1 root oinstall 72416 Aug 12  2015 /u01/app/oracle/product/11.1.0.1/db/bin/oradism




Fix:

If required, shutdown DB and change permission as follows:
sudo su
cd /u01/app/oracle/product/11.1/db/bin
chmod 750 oradism
chmod u+s oradism
Restart instance

or 
run $ORACLE_HOM/root.sh
