\n2.Redhat enterprise linux 6.5(64 bit)
\n3.Oracle database 12C (64 bit)
\n4.Oracle Grid infrastructure 12c(64 bit)<\/p>\n
What to Setup:-<\/p>\n
1. Setup oracle grid infrastructure for standalone server “ASM”
\n2. Setup oracle Database<\/p>\n
Update \/etc\/sysctl.conf
\n[root@server1]# vi \/etc\/sysctl.conf
\nScroll to the bottom and add the following:<\/p>\n
fs.file-max = 6815744
\nkernel.sem = 250 32000 100 128
\nkernel.shmmni = 4096
\nkernel.shmall = 1073741824

\nfs.aio-max-nr = 1048576
\nnet.ipv4.ip_local_port_range = 9000 65500
\n:wq<\/p>\n
Run the following command to change the current kernel parameters.
\n\/sbin\/sysctl -p<\/p>\n
Update \/etc\/security\/limits.conf
\n[root@server1]# vi \/etc\/security\/limits.conf
\nScroll to the bottom and above the \u201c# End of file\u201d line, add:<\/p>\n

Check the kernel version:-
\n[root@server1 var]# uname -r
\n2.6.32-358.el6.x86_64<\/p>\n
Now we would require to install the rpm’s required for asm installation
\nthese are the packages required for asm.<\/p>\n
–oracleasm
\n–oracleasm-support
\n–oracleasmlib
\nthe last 2 packages can be found from the following link
\nhttp:\/\/www.oracle.com\/technetwork\/server-storage\/linux\/asmlib\/rhel6-1940776.html<\/p>\n
oracle kmod-oracleasm rpm download link for el6
\nhttp:\/\/public-yum.oracle.com\/repo\/OracleLinux\/OL6\/latest\/x86_64\/getPackage\/kmod-oracleasm-2.0.6.rh1-2.el6.x86_64.rpm<\/p>\n

\n[root@server3 ~]# rpm -Uvh kmod-oracleasm-2.0.6.rh1-2.el6.x86_64.rpm
\n[root@server3 ~]# rpm -Uvh oracleasmlib-2.0.4-1.el6.x86_64.rpm<\/p>\n
Create groups:-
\n[root@server3 tmp]# groupadd -g 1000 oinstall
\n[root@server3 tmp]# groupadd -g 1200 dba
\n[root@server3 tmp]# useradd -g oinstall -G dba -d \/home\/oracle oracle<\/p>\n
Create directory structures:-
\n[root@server3 u01]# mkdir -p \/u01\/app\/oracle\/product\/12.1.0\/grid
\n[root@server3 u01]# mkdir -p \/u01\/app\/oracle\/product\/12.1.0\/db_1<\/p>\n
Assigning proper permission:-
\n[root@server3 u01]# chown -Rf oracle:oinstall \/u01\/
\n[root@server3 u01]# chmod -Rf 775 \/u01\/<\/p>\n
Set up the oracle user environment
\nFor oracle user:-
\n[root@server1 var]# su – oracle<\/p>\n
[oracle@server1]#vi .bash_profile
\n#export PATH
\n# Oracle Settings
\nTMP=\/tmp; export TMP
\nTMPDIR=$TMP; export TMPDIR

\nalias db_env=’. \/home\/oracle\/db_env’<\/p>\n
:wq(save & exit)<\/p>\n
[oracle@server1 ~]$ . .bash_profile<\/p>\n
Create a file called “\/home\/oracle\/db_env” with the following contents :-<\/p>\n
[oracle@server1 ~]$vi \/home\/oracle\/db_env<\/p>\n
ORACLE_SID=orcl; export ORACLE_SID
\nORACLE_HOME=$DB_HOME; export ORACLE_HOME

Create a file called “\/home\/oracle\/grid_env” with the following contents:-<\/p>\n
[oracle@server1 ~]$vi \/home\/oracle\/gid_env
\nORACLE_SID=+ASM; export ORACLE_SID
\nORACLE_HOME=$GRID_HOME; export ORACLE_HOME

[oracle@server1 ~]$ chmod 775 \/home\/oracle\/db_env
\n[oracle@server1 ~]$ chmod 775 \/home\/oracle\/grid_env<\/p>\n
Now you will be able to switch environments between oracle and asm instance as follows.
\n[oracle@server3 ~]$ db_env
\n[oracle@server3 ~]$ echo $ORACLE_SID
\norcl
\n[oracle@server3 ~]$ echo $ORACLE_HOME
\n\/u01\/app\/oracle\/product\/12.1.0\/db_1
\n[oracle@server3 ~]$ grid_env
\n[oracle@server3 ~]$ echo $ORACLE_HOME
\n\/u01\/app\/oracle\/product\/12.1.0\/grid
\n[oracle@server3 ~]$ echo $ORACLE_SID
\n+ASM<\/p>\n
Now\u00a0 we will add 3 disks using vmware.
\nSo open vmware workstation and go to settings and add hard disk from there,add 3 different disks size of atleast 10GB each.<\/p>\n
[root@server1]# echo “- – -“> \/sys\/class\/scsi_host\/host0\/scan<\/p>\n
******
\nP.S. if the above command doesnt show the newly added disk try this
\n[root@server1]#grep mpt \/sys\/class\/scsi_host\/host?\/proc_name
\n\/sys\/class\/scsi_host\/host2\/proc_name:mptspi<\/p>\n
then run this
\n[root@server1]# echo “- – -“> \/sys\/class\/scsi_host\/host2\/scan
\n******<\/p>\n
using the above command we can avoid rebooting the machine to\u00a0 mount the hard disks.<\/p>\n
