Installation of grid infrastructure software in 11g release 2 involves a stand alone installation or a cluster installation with or without asm disks.
In this example we will install a stand alone grid infrastructure with asm disks and an asm instance.
Configuring Disks for ASM
To ensure that the disks are available, enter the following command:
LN1D:/u01/oracle> /usr/sbin/lsdev -Cc diskhdisk0 Available Virtual SCSI Disk Drivehdisk1 Available Virtual SCSI Disk Drivehdisk2 Available Virtual SCSI Disk Drivehdisk3 Available Virtual SCSI Disk Drivehdisk4 Available Virtual SCSI Disk Drivehdisk5 Available Virtual SCSI Disk Drivehdisk6 Available Virtual SCSI Disk Drivehdisk7 Available Virtual SCSI Disk Drivehdisk8 Available Virtual SCSI Disk Drive
LN1D:/u01/oracle> ls -l /dev | grep asmcrw-rw---- 1 oracle dba 17, 4 Feb 16 14:31 asm_disk1crw-rw---- 1 oracle dba 17, 2 Feb 16 14:31 asm_disk2crw-rw---- 1 oracle dba 17, 1 Feb 16 14:31 asm_disk3crw-rw---- 1 oracle dba 17, 8 Feb 16 14:31 asm_disk4crw-rw---- 1 oracle dba 17, 3 Feb 16 14:31 asm_disk5crw-rw---- 1 oracle dba 17, 7 Feb 16 14:31 asm_disk6crw-rw---- 1 oracle dba 17, 5 Feb 16 14:31 asm_disk7
Create a staging area for the software and then begin the installation –
Software zip file copied to an unzipped to create foll directory .
/u01/oracle/software/11g_gridinfrastructure/grid
Get rootpre.sh run from the same area above with root user.
export DISPLAY=10.107.105.182:0.0 = Your laptop’s ip address.
Launch installer –
LN1D:/u01/oracle/software/11g_gridinfrastructure/grid> ./runInstaller********************************************************************************
Your platform requires the root user to perform certain pre-installationOS preparation. The root user should run the shell script 'rootpre.sh' beforeyou proceed with Oracle installation. rootpre.sh can be found at the top levelof the CD or the stage area.
Answer 'y' if root has run 'rootpre.sh' so you can proceed with Oracleinstallation.Answer 'n' to abort installation and then ask root to run 'rootpre.sh'.
********************************************************************************
Has 'rootpre.sh' been run by root? [y/n] (n)y

Click on Change Discovery Path and enter /dev/asm* - ok
Click on external and 5 disks and next – Ensure disk group is named DATA
Click ok once completed
At this stage Oracle starts up the css services – cluster services –this must run even if RAC is not used –
LN1D:/u01/oracle> ps -ef |grep css oracle 299010 335872 0 13:46:07 pts/1 0:00 grep css oracle 418028 1 0 13:08:40 - 0:01 /u01/oracle/product/11.2.0/grid/bin/cssdagent oracle 503818 1 3 13:09:06 - 0:10 /u01/oracle/product/11.2.0/grid/bin/ocssd.bin
Close
Check ASM instance and cluster services –
LN1D:/u01/oracle> ps -ef |grep pmon oracle 483352 1 0 13:10:19 - 0:00 asm_pmon_+ASMLN1D:/u01/oracle>

Add second disk group called FRA – using asmca from gridinfrastructure home.
Create listener config from gridinfrastructure home/bin

Make sure listener.ora in the grid home has entry for ASM – Otherwise dbca will not create a new db and configure it via the asm instance –
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = +ASM) (ORACLE_HOME = /u01/oracle/product/11.2.0/grid) (SID_NAME = +ASM) ) )
LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = DEVU042)(PORT = 1521)) ) )
