In today’s threat landscape, where vulnerabilities can be exploited within hours, patching is no longer a

routine maintenance task, it is a critical security operation. Oracle’s latest 26ai and 19c Release Updates (RU) introduce a set of innovations designed to make patching faster, safer, and less disruptive, especially on Oracle RAC as sessions can be drained seamlessly. Additionally, customers using one instance can benefit from rolling patching using Oracle 26ai Single Server Rolling Database Maintenance feature.

Patch Critical Vulnerabilities without Downtime

One of the most impactful enhancements is the ability to patch Java Runtime Environment (JRE) vulnerabilities without stopping the database or Grid Infrastructure. This allows organizations to: 

  • Apply critical security fixes immediately
  • Eliminate emergency maintence windows 
  • Maintain services during patching

Patches can be applied using the familiar tools like FPP (Fleet Provisioning and Patching) or opatchauto without any additional command line options.

Reduce Risk with a Modernized Software Stack

Oracle is simplifying the software stack by replacing Apache Tomcat application server with Micronaut framework. Micronaut framework reduces operational risk by:

  • Lowering exposure to frequently targeted components 
  • Eliminating the need for a full application server layer
  • Reducing overall runtime complexity 

This change helps reduce the frequency of urgent patch cycles and improves overall platform stability.

Standardize Patching with Integrated Gold Images 

Release Updates as shown in the image below, now include a complete gold image, enabling a consistent out-of-place patching workflow.

Canned GoldImage

With Gold images, teams can:

  • Deploy a new GI and Oracle home from gold images 
  • Perform a switch home operation during maintenance windows
  • Improve patching reliability abd reduces configuration drift

 Additionally, Oracle FPP 26ai now includes a local mode option which runs locally on the database server itself and does not require a separate setup, greatly simplifying Gold image based patching operations. 

Enable Continuous Security Without Compromising Availability

These enhancements collectively reduce operational complexity and risk. By standardizing on out-of-place patching and gold images, organizations can:

  • Minimize downtime
  • Avoid patch failures due to environmental inconsistencies
  • Streamline patching processes

Oracle’s latest innovations reflect a broader shift toward continuous, low-impact security operations. With the ability to patch critical vulnerabilities without downtime and standardize deployment workflows, organizations can significantly reduce their exposure window while maintaining high availability.

Get Started

The shift to zero-downtime patching marks a turning point in how organizations approach database security. What was once a disruptive, high-risk activity is now a continuous, predictable process. DBAs and platform teams should:
