Upgrading the Grid Infrastructure from 11.2.0.4 to 12.1.0.2 on the command line

Currently I have two node Grid Infrastructure on 11.2.0.4. The node names are node1 and node2:

[grid@node1 ~]$ crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [11.2.0.4.0]

[grid@node1 ~]$ crsctl query crs softwareversion
Oracle Clusterware version on node [node1] is [11.2.0.4.0]

[grid@node1 ~]$ crsctl query crs softwareversion node2
Oracle Clusterware version on node [node2] is [11.2.0.4.0]

Now we are extracting the source files for 12.1.0.2 and make necessary folder.

[grid@node1 ~]$ cd /u01/app/oracle/software/
[grid@node1 software]$ ls -l
total 2337928
-rw-r--r--. 1 grid oinstall 1747043545 Aug 5 15:14 linuxamd64_12102_grid_1of2.zip
-rw-r--r--. 1 grid oinstall 646972897 Aug 5 15:14 linuxamd64_12102_grid_2of2.zip
[grid@node1 software]$ unzip linuxamd64_12102_grid_1of2.zip
[grid@node1 software]$ unzip linuxamd64_12102_grid_2of2.zip

[root@node1 app] mkdir /u01/app/12.1.0.2/
[root@node1 app] chown grid:oinstall /u01/app/12.1.0.2/
[root@node1 app] ssh node2
root@node2's password:
Last login: Thu Nov 5 14:52:57 2015 from node1
[root@racp1vm2 ~] mkdir /u01/app/12.1.0.2/
[root@racp1vm2 ~] chown grid:oinstall /u01/app/12.1.0.2/

Now we creating the response file for installation of new grid on both nodes.

cat /tmp/grid_install.rsp

ORACLE_HOSTNAME=node1.localhost
INVENTORY_LOCATION=/u01/app/oraInventory
SELECTED_LANGUAGES=en
oracle.install.option=UPGRADE
ORACLE_BASE=/u01/app/grid
ORACLE_HOME=/u01/app/12.1.0.2/
oracle.install.asm.OSDBA=asmdba
oracle.install.asm.OSOPER=asmoper
oracle.install.asm.OSASM=asmadmin
oracle.install.crs.config.clusterName=racp1vm-cluster
oracle.install.crs.config.gpnp.configureGNS=false
oracle.install.crs.config.autoConfigureClusterNodeVIP=true
oracle.install.crs.config.gpnp.gnsOption=CREATE_NEW_GNS
oracle.install.crs.config.clusterNodes=node1:,node2:
oracle.install.crs.config.storageOption=LOCAL_ASM_STORAGE
oracle.install.crs.config.sharedFileSystemStorage.votingDiskRedundancy=NORMAL
oracle.install.crs.config.sharedFileSystemStorage.ocrRedundancy=NORMAL
oracle.install.asm.diskGroup.name=CRS
oracle.install.asm.diskGroup.AUSize=1
oracle.install.crs.config.ignoreDownNodes=false
oracle.install.config.managementOption=NONE

Now we are installing grid home with response file.

[grid@node1 software]$ cd grid
[grid@node1 software]$ ./runInstaller -slient -responseFile /tmp/db_install.rsp -ignoreSysPrereqs -ignorePrereq -waitforcompletion

After completion we get the output

As a root user, execute the following script(s):
1. /u01/app/12.1.0.2/rootupgrade.sh

Execute /u01/app/12.1.0.2/rootupgrade.sh on the following nodes:
[node1, node2]

Run the script on the local node first. After successful completion, you can start the script in parallel on all other nodes, except a node you designate as the last node. When all the nodes except the last node are done successfully, run the script on the last node.

Successfully Setup Software.
As install user, execute the following script to complete the configuration.
1. /u01/app/12.1.0.2/cfgtoollogs/configToolAllCommands RESPONSE_FILE=

Note:
1. This script must be run on the same host from where installer was run.
2. This script needs a small password properties file for configuration assistants that require passwords (refer to install guide documentation).

Upgrade on the first node:

[root@node1 ~] /u01/app/12.1.0.2/rootupgrade.sh
Check /u01/app/12.1.0.2/install/root_node1.localhost_2017-07-23_12-32-03.log for the output of root script

Log Output for Node 1

<<Output Truncated>>

2017/07/23 12:41:44 CLSRSC-474: Initiating upgrade of resource types

2017/07/23 12:41:50 CLSRSC-482: Running command: 'upgrade model -s 11.2.0.4.0 -d 12.1.0.2.0 -p first'

2017/07/23 12:41:52 CLSRSC-325: Configure Oracle Grid Infrastructure for a Cluster ... succeeded

Now upgrade the second node

[root@node2 ~] /u01/app/12.1.0.2/rootupgrade.sh
Check /u01/app/12.1.0.2/install/root_node2.localhost_2017-07-23_13-43-30.log for the output of root script

Log Output for Node 2

<<Output Truncated>>

We can confirm the version

2017/07/23 12:41:50 CLSRSC-482: Running command: 'upgrade model -s 11.2.0.4.0 -d 12.1.0.2.0 -p first'

2017/07/23 12:41:52 CLSRSC-325: Configure Oracle Grid Infrastructure for a Cluster ... succeeded

We can confirm the version

[root@node2 ~] /u01/app/12.1.0.2/bin/crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [12.1.0.2.0]
[root@node2 ~] /u01/app/12.1.0.2/bin/crsctl query crs softwareversion
Oracle Clusterware version on node [node2] is [12.1.0.2.0]

Cheers!! Upgrade done
