Before installation, Oracle Universal Installer checks the environment to see whether it meets the requirements for successful installation. Early detection of problems with the system setup reduces the chances for you to encounter problems during installation; for instance, problems with insufficient disk space, missing patches, inappropriate hardware, and so forth.
This screen shows the name, type, and status for all prerequisite checks designed for the installation. Automatic checks are run first, followed by optional and manual checks. You cannot disable automatic checks; run optional checks at your discretion; manual checks must be verified by filling in the selection box. As each check runs, a progress bar is shown, and test details (expected results, actual results, error messages, instructions, and so forth) are displayed in the details window. To stop all prerequisite checks, click Stop.
After the prerequisite checker finishes running all checks, it displays a status summary indicating the number of checks that failed and the number that require verification. A check may require verification if a warning was produced during execution or you did not confirm a manual check. You must manually verify all warning and manual checks by filling in the selection box. Once you confirm a check, you are taken to the next check to be confirmed. Click a prerequisite check to view its corresponding details, including recommended user actions.
To retry failed, skipped (stopped by user), and warning checks, click Retry.
Note: For manual checks, the selection boxes must be filled in manually.
To continue without retrying, click Next.
