installation process:
Installation Option:
Install
and Configure Grid Infrastructure for a Cluster
Installation Type:
Advanced Installation
Product Language:
English
Grid Plug and Play:
Cluster Name: lab
SCAN Name: lab-scan.hingu.net
SCAN Port: 1521
Configure GNS: Unchecked
Cluster Node Information:
Entered the Hostname and VIP names of the
Cluster Nodes.
Checked the SSH connectivity
Network Interface Usage:
OUI picked up all the interfaces correctly. I
did not have to make any changes here.
Storage Option:
Automatic Storage Management (ASM)
Create ASM Disk Group:
Disk Group Name: GIS_FILES
Redundancy: External
Candidate Disk: ORCL:DSK01
ASM Password:
Use Same Password for these accounts. (Ignored
password warnings.)
Failure Isolation:
Do not use Intelligent Platform Management
Interface (IPMI)
Operating System Groups:
ASM Database Administrator (OSDBA) Group:
asmdba
ASM Instance Administrator Operator (OSOPER)
Group: oinstall
ASM Instance Administrator (OSASM) Group:
asmadmin
Installation Location:
Oracle Base: /u01/app/grid
Software Location: /u01/app/grid11201
Create Inventory:
Inventory Directory: /u01/app/oraInventory
Prerequisite Checks:
Ignored the failures of NTP check to use
Oracle’s CTSS. All the 3 nodes’ clock
was set to same time before the installation.
Summary Screen:
Verified the information here and pressed
“Finish” to start installation.
At the End of the
installation, the two scripts needs to be executed as root user.
/u01/app/oraInventory/orainstRoot.sh
/u01/app/grid11201/root.sh
After the successful
completion of these scripts, the 11g R2 High Availability Service (CRS, CSS and
EVMD) should all be up and running.
Verify the status of
the installation using below set of commands.
crsctl check cluster –all
crs_stat –t –v
crsctl check ctss
The GSD and OC4J
resources are by default disabled. Enable GSD them if 9i Database is managed by
this cluster.
srvctl enable nodeapps –g
srvctl start nodeapps –n node1
srvctl start nodeapps –n node2
srvctl start nodeapps –n node3
srvctl enable oc4j
srvctl start oc4j
Here is the Screenshots of the Grid
Infrastructure Installation:
With the Successful
installation of 11g R2 Grid Infrastructure (11.2.01), Next is to install 11g R2
RAC (database 11.2.0.1) software and create a RAC database.
