Oracle Faq

Hi All,

I was trying using Oracle Enterprise Manager to start the database/Listener and when I tried to start the database/listener through OEM i got the following error

RemoteOperationException: ERROR: NMO not setuid-root (Unix-only)

Later on I discovered that the error was since the root.sh script was not run properly.

Then i tried to rerun the root.sh which is located in $ORACLE_HOME/root.sh the

above error disapperad. It was because the improper permissions on oracle binaries in particular nmo,nmhs,nmb binaries.

Later on after running the root.sh the following permission were giving the nmo,nmhs and nmb binaries

-rwsr-s—   1 root   oinstall     23744 Oct 15 16:17 nmo
-rwsr-x—   1 root   oinstall     46480 Oct 15 16:17 nmhs
-rwsr-s—   1 root   oinstall     17256 Oct 15 16:17 nmb 

Here ’s’ stands for that SUID bit is set for this binaries

#!/bin/bash
ORACLE_SID=OTM;export ORACLE_SID
echo $ORACLE_SID

echo “Please Specify the kind of backup you want to take”
echo “1) COLD BACKUP”
echo “2) HOT BACKUP”
echo “3) EXPORT BACKUP”
echo “Enter your option”

read option

while [ $option -gt 3 ]||[ $option -le 0 ]
do
echo “Please Enter the correct option”
read option
done

case $option in
1|2) echo “You are taking rman backup of DB”
   rman target sys/sys @/oracle/product/11g/rman_backup_$option.txt;exit;;
3) echo “You are taking export backup of DB”
   exp system/sys file=/oracle/exp_dat.dmp log=/oracle/exp_dat.log full=y;
   exit;;
