It has been an exciting week, Oracle 12c R2 came out and suddenly was time to refresh the RAC test environments. My friend Jacques opted for an upgrade from 18.104.22.168 to 22.214.171.124 (here the link to his blog post), I started with a fresh installation, because I also upgraded the Operating System to OEL 7.3.
Compared to 12c R1 there are new options on the installation process, but general speaking the wizard is quite similar.
The first breakthrough is about the installation simplified with an image based, no more runIstaller.sh to invoke but …
Unpack the .Zip file directly inside the Grid Infrastructure Home of the first cluster node as described below:
[grid@oel7node06 ~]$ mkdir -p /u01/app/126.96.36.199/grid [grid@oel7node06 ~]$ chown grid:oinstall /u01/app/188.8.131.52/grid [grid@oel7node06 ~]$ cd /u01/app/184.108.40.206/grid [grid@oel7node06 grid]$ unzip -q download_location/grid_home_image.zip # From an X session invoke the Grid Infrastructure wizard: [grid@oel7node06 grid]$ ./gridSetup.sh
The second screenshot list the new Cluster typoligies available on 12c R2:
- Oracle Standalone Cluster
- Oracle Cluster Domain
- Oracle Domain Services Cluster
- Oracle Member Clusters
- Oracle Member Cluster for Oracle Database
- Oracle Member Cluster for Applications
In my case I’m installing an Oracle Standalone Cluster
And now time for testing.
