Review the Licensing Information

You are permitted to use only those components in the Oracle Database media pack for which you have purchased licenses. For more information, see:

Oracle Database Licensing Information

Run OUI with CVU and use fixup scripts

Oracle Universal Installer is fully integrated with Cluster Verification Utility (CVU), automating many CVU prerequisite checks. Oracle Universal Installer runs all prerequisite checks and creates fixup scripts when you run the installer. You can run OUI up to the Summary screen without starting the installation.

You can also run CVU commands manually to check system readiness. For more information, see:

Oracle Clusterware Administration and Deployment Guide

Download and run Oracle ORAchk for runtime and upgrade checks, or runtime health checks

The Oracle ORAchk utility provides system checks that can help to prevent issues after installation. These checks include kernel requirements, operating system resource allocations, and other system requirements.

Use the Oracle ORAchk Upgrade Readiness Assessment to obtain an automated upgrade-specific system health check for upgrades. For example:

./orachk -u -o pre

The Oracle ORAchk Upgrade Readiness Assessment automates many of the manual pre- and post-upgrade checks described in Oracle upgrade documentation.

Oracle ORAchk is supported on Windows platforms in a Cygwin environment only. For more information, see:


Ensure cron jobs do not run during installation If the installer is running when daily cron jobs start, then you may encounter unexplained installation problems if your cron job is performing cleanup, and temporary files are deleted before the installation is finished. Oracle recommends that you complete installation before daily cron jobs are run, or disable daily cron jobs that perform cleanup until after the installation is completed.
Obtain Your My Oracle Support account information

During installation, you require a My Oracle Support user name and password to configure security updates, download software updates, and other installation tasks. You can register for My Oracle Support at the following URL:


Check running Oracle processes, and shut down processes if necessary
  • On a node with a standalone database not using Oracle ASM: You do not need to shut down the database while you install Oracle Grid Infrastructure.

  • On a node with a standalone Oracle Database using Oracle ASM: Stop the existing Oracle ASM instances. The Oracle ASM instances are restarted during installation.

  • On an Oracle RAC Database node: This installation requires an upgrade of Oracle Clusterware, as Oracle Clusterware is required to run Oracle RAC. As part of the upgrade, you must shut down the database one node at a time as the rolling upgrade proceeds from node to node.
