Oracle 12c install live blog

Ok, so Oracle 12c has been available for download since earlier today and since I already had my Oraclenerd shirt on, this means some serious playtime is called for.

I though it would be fun and/or interesting to blog about all the steps I did to install 12c and share it. So first step was to download the software from edelivery. Note that since this is not a download from OTN (which would fall under the OTN developer license) you may want to think about licensing. Not a huge problem for us, being an OPN ISV partner.
Update 21:30 CET: The download is available on OTN now aswell.

Sadly, the only port or version available is for Linux, I can only assume that Solaris versions will be available later (update 20:00CET: Solaris sparc and x64 versions now available aswell). I downloaded the two parts (total 2,3GB) of “Oracle Database 12c Release 1 ( Media Pack for Linux x86-64″ in just a few minutes.

Next step: find a suitable machine to install this on. We have a pool of Oracle VM servers and a template for Oracle Linux 6 ready to clone. A few minutes later I have a fresh machine to play with.

Had to pause the installation progress to follow the OPN partnercast and FY14 kickoff. But we won a free pass to OpenWorld with this picture. WooHoo!

The VM template created a 12GB boot disk but I figured that I’ll need a bit more to install the software so I created a new disk. The storageconnect plugin and the ZFS storage appliance make this really easy since you don’t even have to open up a new admin interface and can simply create the iSCSI LUN from the OVM manager. I also added the virtual network interface, notice the last byte of the mac address: 0x0c is 12 in decimal.


Start up the machine and bring up the VNC console, answer some basic questions about the desired hostname, IP address and so on and a few minutes later you are all set with the linux VM. Usually I’d run a yum update at this point but today is more about getting the database software installed as quickly as possible.

Partition, format and mount the extra disk I created earlier:

[root@ora12c ~]# fdisk /dev/xvdb

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

[root@ora12c ~]# echo "/dev/xvdb1              /u01                    ext3    defaults        0 2" >> /etc/fstab
[root@ora12c ~]# mount /u01

Copy the downloaded zipfiles (i put them at /u01/download/) and extract with the unzip command. On my first overly excited try, I tried to run the installer as root which is still not allowed:

[root@ora12c database]# ./runInstaller 

The user is root. Oracle Universal Installer cannot continue installation if the user is root.

So I quickly chowned /u01 to the oracle user, set a password for it (the user and groups were already set up in this template) and reconnected as oracle making sure to use the -X option to ssh to forward the X11 protocol for the GUI installer. And off we go:

[oracle@ora12c database]$ ./runInstaller 
Starting Oracle Universal Installer...

Preparing to launch Oracle Universal Installer from /tmp/OraInstall2013-06-25_02-24-35PM. Please wait ...

The installer itself has not changed (much?) since 11g, I opted to only install the software first and run dbca myself later and accepted all the other default options. Swap was not big enough but I chose to ignore this rather than fix it now. The one thing I missed was the nice flashy ads for new features while the software actually installs. There was just a red 12c banner there.













There are still scripts to be run as root:

[root@ora12c oraInventory]# ./ 
Changing permissions of /u01/app/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.

Changing groupname of /u01/app/oraInventory to oinstall.

The following environment variables are set as:
    ORACLE_OWNER= oracle
    ORACLE_HOME=  /u01/app/oracle/product/12.1.0/dbhome_1

Enter the full pathname of the local bin directory: [/usr/local/bin]: 
   Copying dbhome to /usr/local/bin ...
   Copying oraenv to /usr/local/bin ...
   Copying coraenv to /usr/local/bin ...

Creating /etc/oratab file...
Entries will be added to the /etc/oratab file as needed by

Finished running generic part of root script.
Now product-specific root actions will be performed.

And that’s it for the installation.

DBCA has a few more and new options and I’ll go (and guess) through them

[oracle@ora12c ~]$ export ORACLE_HOME=/u01/app/oracle/product/12.1.0/dbhome_1
[oracle@ora12c ~]$ export ORACLE_SID=ORCL12
[oracle@ora12c ~]$ /u01/app/oracle/product/12.1.0/dbhome_1/bin/dbca

The very first screen has a new (but greyed out for now) option of “Manage Pluggable Databases”. I guess this would be available after I set up a container DB first.

What upset me on the second screen was the default DB character set of WE8MSWIN1252. Who uses that? I quickly changed it to AL32UTF8 and entered a (too) simple password.


Only then did I see the option to enter a PDB name (whatever that is?) and even more interesting: A button for an “Advanced Mode” installation. I am feeling adventurous today and choose that option.



There is a new option allowing me to setup this DB as a container DB for PDB. I guess that is a good thing and selected to create two PDBs aswell.



Again, there is a warning because my password of ‘oracle’ is too simple. Kids, only try this at home, do not use a simple password like that in production.


This next page confused me. I selected the one listener that was mentioned and tried next but I had to enter something for the name and port so I went with LISTENER and 1521 which may have been a bad choice as you will see later







Interesting. I cannot change the default block size but I also don’t care since I would have chosen 8k anyway.


Again, I don’t care much about anything but UTF








A few moments after the creation started, an error popped up saying that I was not supposed to create another listener with an existing name.


So I started the whole process all over again and this time there was already a listener with a status of “up”. I did not change anything, just clicked next and went on with dbca.





And that was it! The instance was started, the database open and I could simply connect.

Oh, and lsnrctl shows that my pluggable databases have registered as services:

And I’ll better stop here for today even though I would love to read through all the documentation and play with the cool new features but I’ll better leave some stuff for tomorrow and the next days.

And I already have a long list of features that I know I want to play with.
