How to Install Oracle 11g on Linux with ASM

Step -1

Ensure /dev/shm is large enough. It should be set to the size of the physical RAM minus 4GB. (Or an appropriate amount reserved for the OS)

·         cd /dev/shm

·         df -h .

Step-2

Ensure oracle account and dba group exists.

Step-3

Install oel6 rpm

Step-4

Add hard disk in linux machine

root@pansoft100 Desktop]# fdisk /dev/sdb

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to

         switch off the mode (command 'c') and change display units to

         sectors (command 'u').
