create the monitor.sh

Step first..we create the monitor.sh file in home "/home"

[root@ab home]#cat > monitor.sh
[root@ab home]#vi monitor.sh
###add following lines to the file

................................................

step 2nd -  :wq (save & exit)

step 3rd- give permission to that file

[root@ab home]# chmod 755 monitor.sh

step 4- copy that file to /usr/bin

[root@ab home]# cp -avf monitor.sh /usr/bin/monitor

step 5- go to root bash_profile
#####add these lines

[root@ab ~]#  vi .bash_profile
 
alias m=monitor

step 6 - :wq (save & exit)

Step 7 - Sheduled the crontab

crontab -e

25 13 * * * /home/monitor.sh



Step 8 - now logout & connect again and check status

---------------------------------------------------------

now check

[root@ab ~]# m 99

Multiplexing of control files

.................Multiplexing of control files.....................




Firstly we need to create a mount point where we want to store the redo logs.
mkdir /redoa
mkdir /redob
mkdir /redoc

then gven the permission and owner to the mount points;

chmod -Rf 777 /redoa
chmod -Rf 777 /redob
chmod -Rf 777 /redoc

chown -Rf oracle:oinstall /redoa
chown -Rf oracle:oinstall /redob
chown -Rf oracle:oinstall /redoc

===> 1st step--- create a directory where the the backup will store:-

[root@ab ~] mkdir /backups

[root@ab backups] mkdir /backups/db_backup

====> 2nd step  create a directory where script will store:-


[root@ab] mkdir /backups/script
