Oracle 12c DB installation

Oracle 12c DB installation

Here are the easy steps to install the Oracle 12c (12.1.0.2)  Database.

Steps 1: Setup your server with required space and user creation.

[root@ol5-12c-cdb ~]# groupadd oinstall
[root@ol5-12c-cdb ~]# useradd -g oinstall oracle
[root@ol5-12c-cdb ~]# passwd oracle

We will use below dir's for 12c DB software installation.

Oracle Base: /u01/app/oracle
DB Home: /u01/app/oracle/product/12.1.0/dbhome_1

Inventory: /u01/app/oraInventory

[root@ol5-12c-cdb ~]# xhost +
access control disabled, clients can connect from any host
[root@ol5-12c-cdb ~]# su - oracle
[oracle@ol5-12c-cdb ~]$ cd  /media/sf_Oracle_Base/sw12.1.0.2db/database
[oracle@ol5-12c-cdb database]$ ./runInstaller

[Step1]  If you have valid credentials and the server is connected to the Internet, then you should provide these details. Otherwise, you can skip this option and configure them after installation.



[Step-2] Select "Install Database software only"
We will create the container database along with PDB's in later posts.



[Step-3] Select "Single instance database instance" and click next..



[Step-4]Select your preferred language and click next..



[Step-5] Click Next..



[Step-6] Provide directory paths for oracle base and oracle home software.



[Step-7] Provide path for Central Inventory. Select group as oinstall.

[Step-9] We may ignore this error and proceed further with installation.



[Step-10] It lists all the details, Review once and click Install.



[Step-11] Installation is in Progress...



[Step-12] Once after installation we need to run below scripts as a root user.

/u01/app/oraInventory/orainstRoot.sh
/u01/app/oracle/product/12.1.0/dbhome_1/root.sh
