Install Database 12.1.0.2 Software

Three things need to do:

1. Upgrade Grid Infra from 11gR2(11.2.0.3) to 12C(12.1.0.2)
2. Install Database Software12C(12.1.0.2)
3. Upgrade DB from 11gR2 to 12C

Prepare Installation Software

Unzip the 12.1.0.2 database software.  Run the following command on the database server where the software is staged.

(oracle)$ unzip -q /u01/app/oracle/patchdepot/linuxamd64_12c_database_1of2.zip -d /u01/app/oracle/patchdepot (oracle)$ unzip -q /u01/app/oracle/patchdepot/linuxamd64_12c_database_2of2.zip -d /u01/app/oracle/patchdepot

Create the new Oracle DB Home directory on all database server nodes

Node 1 and Node 2:

mkdir -p /u01/app/oracle/product/12.1.0.2/db_1

Perform 12.1.0.2 Database Software Installation with the Oracle Universal Installer (OUI)

[oracle@ol6-112-rac1 database]$ ./runInstaller
