The data dictionary for the database is upgraded to the new release. Upgrading does not directly affect user data; no data is touched, changed, or moved during an upgrade.

Supported Direct Upgrade Paths : Oracle Database 10g (10.2.0.5) Oracle Database 11g (11.1.0.7) Oracle Database 11g (11.2.0.2 ) Oracle Database 11g (11.2.0.4 ) Oracle Database 12g (12.1.0.2 ) Upgrading Oracle Database 11.2.0.1 to 11.2.0.4 (Oracle 11g) We cannot upgrade directly from Oracle 11.2.0.1 to 12.1.0.2 so we need to upgrade to 11.2.0.4 before doing the 12c upgrade. Oracle Database 11gR2 (11.2.0.4) installation on Oracle Linux 6.5 This part will to about oracle 11.2.0.4 patch installation In this part, I’m going to install the Oracle Database 11g Release 2 (11.2.0.4) software on Oracle Linux 6.5, with instructions on how to apply the latest Patch Set Update (PSU) to your new Oracle home. Before you start, make sure your Linux server meets the minimum hardware requirements: 1GB of RAM (plus appropriately sized swap space) 4.5GB of disk space for the software installation 1GB of disk space for your /tmp directory make sure that the ‘oracle’ user has correct ownership of the /u01 mount point, and that the ‘oracle’ account has a password set. chown -R oracle:oinstall /u01 chmod -R 775 /u01 Package and OS requirements In this example, I’m meeting the package and Operating System requirements by running the following yum command (as root): yum install oracle-rdbms-server-11gR2-preinstall This pre-install package will meet the necessary configuration tasks for you, and whilst the name implies it’s for installing Oracle Database Server 11gR2 software, it’s also a useful starting point to prepare your system for installing other Oracle software. Also, make sure that the ‘/etc/hosts’ file contains a Fully Qualified Domain Name (FQDN) for your server, for example: [[email protected] ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.48.150 srv-orcl11g-01.localdomain srv-orcl11g-01 [[email protected] ~]# Check your linux OS system
