Changes in this Release for Oracle Database

New Features

Oracle Database 19c introduces Oracle Memory Speed support for persistent memory devices through an XFS-based, DAX-enabled file system; installer options to automate required root configuration scripts while retaining manual execution; and simplified image-based Oracle Database client installation, where extracted client images are installed using the runInstaller script.

Deprecated Features

Oracle Database 19c deprecates ASM Filter Driver on Linux and Oracle Solaris, with ASMFD filtering unsupported on Linux kernel 5.14 and later and ASMlib v3 recommended as an alternative; the clone.pl script, which is replaced by installer-based gold image deployment; the SERVICE_NAMES parameter for all high-availability operations; and Oracle ACFS on IBM AIX, for which GPFS may be used for eligible files. ASMFD remains supported on Oracle Solaris until formal desupport.

Other Changes

In Oracle Database 19c and Oracle Grid Infrastructure 19c, Rapid Home Provisioning is renamed Fleet Patching and Provisioning. Linux installation documentation now lists required operating system package names without exact versions; users should install the latest packages available from the minimum supported distribution, using only packages officially released by Oracle or the operating-system vendor.
