New Features
Review new features available with Oracle Database installation in Oracle Database 19c.
Oracle Memory Speed Support for PMEM Devices
Oracle recommends that you use Oracle Database with the Oracle Memory Speed (OMS) file system to fully utilize the potential of persistent memory (PMEM) devices safely in data centers.
With PMEM as the backing device, OMS utilizes a memory-mapped file hosted on an XFS-based, DAX-enabled file system to perform I/O operations. You must export the PMEM device as a file using a DAX-enabled file system, such as XFS.

Root Scripts Automation Support for Oracle Database Installation
Starting with Oracle Database 19c, the database installer, or setup wizard, provides options to set up permissions to run the root configuration scripts automatically, as required, during a database installation. You continue to have the option to run the root configuration scripts manually.
Setting up permissions for root configuration scripts to run without user intervention can simplify database installation and help avoid inadvertent permission errors.

Simplified Image-Based Oracle Database Client Installation
Starting with Oracle Database 19c, the Oracle Database client software is available as an image file for download and installation. You must extract the image software into a directory where you want your Oracle home to be located, and then run the runInstaller script to start the Oracle Database client installation. Oracle Database client installation binaries continue to be available in the traditional format as non-image zip files.
As with Oracle Database and Oracle Grid Infrastructure image file installations, Oracle Database client image installations simplify Oracle Database client installations and ensure best practice deployments.
