8.2.2.3 Critical Hot Updates for Oracle Linux Kernel and Oracle Database Interim Fixes

Oracle Linux and Oracle Database support applying qualified critical updates while the system continues running.

In addition to Exadata Live Update, Oracle provides hot updates, which are critical fixes that can be applied and activated without restarting the system. Hot updates are typically used when a critical fix must be applied before the next planned software maintenance. They are supported for qualified fixes to the following components:

• Oracle Database, using OPatch Online Patching. See RDBMS Online Patching Aka Hot Patching (My Oracle Support Doc ID KB140524).

• Oracle Linux kernel on Exadata database servers and storage servers.

  Oracle Exadata System Software release 26.2.0 introduces Exadata Autonomous Kernel Update, an opt-in capability that provides autonomous online kernel Ksplice updates to Oracle Exadata database servers and storage servers. See Using Exadata Autonomous Kernel Update.

  Exadata Autonomous Kernel Update provides an automated alternative to preexisting manual Oracle Linux kernel update procedures described in Installing Kernel Updates on Exadata Database Servers and Installing Kernel Updates on Oracle Exadata Storage Servers.
