New features for Oracle Database 18c.

Simplified Image-based Oracle Database Installation

Starting with Oracle Database 18c, the Oracle Database software is available as an image file for download and installation. You must extract the image software into the directory where you want your Oracle home to be located, and then run the runInstaller script to start the Oracle Database installation.

Read-Only Oracle Home

Starting with Oracle Database 18c, if you choose a read-only Oracle home, then the database tools and processes write under the ORACLE_BASE path instead of under the Oracle home directory.

A read-only Oracle home separates the software from the database configuration information and log files. This separation enables you to easily share the software across different deployments. A read-only Oracle home also simplifies version control and standardization.

Local Switch Home for Applying Updates

Starting with Oracle Database 18c, the database home includes a built-in tool for switching from the current home to the new home. This tool provides a single command that performs all the necessary steps to apply updates or to rollback from the new home to the previous home.
