In this post I am going to share the steps for installation off Oracle Database 12c on Oracle Enterprise Linux 6.4. Software and resources which will be used: 1. Virtual Box 6.0 2. Oracle Enterprise Linux 6.4 3. Oracle Database 12c(12.1.0.2) Configuration of Virtual Machine: OS: OEL 6.4 RAM: 5 GB Hard Disk: 60GB Oracle Virtual Box installation and Oracle Enterprise Linux steps I will not be sharing here as I have already shared those in my older posts.Please refer link below. 1. Oracle Virtual Box Installation Steps 2. Creating Virtual Machine Steps 3. Installing Oracle Linux Steps 4. Installing Oracle Linux Steps Continued Steps 5. Installing Guest Addition in Machine Steps (Only Guest addition steps needs to be performed from the post). 6. Once the Machine is Prepared Below is the configuration ScreenShot. 7.  We will install pre-requisite RPM's required for Oracle installation as below command. This would be done from root user. # yum...

If we are trying to  install R12.2 EBS, there may be cases that we end up in error during installation. We need to fix the error and then restart the Rapid wiz from beginning as there is no rapidwiz -restart option available with 12.2. If the installation fails we need to perform the following steps to clean up a failed installation: 1. Restart the server or make sure to kill ALL oracle and applmgr processes. 2. Backup and then delete all contents(files/folders) from  the /tmp directory. 3. Backup and then delete all contents(files/folders)  from the oraInventory directory. 4. Backup and then delete BEA under installation user $HOME. 5. Backup and then delete all contents(files/folders)  the install directory- Database / Application Base directory 6. Ensure the correct oraInventory is present and run rapidwiz again to start installation.
