Applying Oracle Database 19c April 2026 Release Update (19.31 RU) on Oracle Restart in AWS EC2

Introduction

Keeping Oracle Database environments up to date is a critical responsibility for database administrators to ensure system stability, security, performance, and long-term support. Oracle’s Release Updates (RUs) are cumulative quarterly patch bundles that include security fixes, bug fixes, optimizer improvements, and stability enhancements for both Oracle Database and Grid Infrastructure.

In this blog, we will walk through the complete patching process for a standalone Oracle Database 19c environment running on an AWS EC2 instance with Oracle Restart (Single Instance High Availability — SIHA). The activity covers applying the April 2026 Release Update (19.31 RU), along with the latest Oracle Java Development Kit (JDK) Bundle Patch and Oracle JavaVM (OJVM) Release Update.

The article demonstrates an end-to-end patching methodology, including environment preparation, prerequisite validation, OPatch upgrade, conflict analysis, OPatchAuto execution, SQL patch application, and post-patching verification. It also highlights best practices and common validation steps that every DBA should perform before and after patching.

By following this guide, database administrators can confidently patch Oracle Restart environments with minimal downtime while ensuring the database remains secure, fully supported, and compliant with Oracle’s recommended maintenance practices.

Environment

The following environment was used to demonstrate the patching procedure described in this article.

Patches Applied

The following patches are included in this maintenance activity:

High-Level Patching Workflow

The patching process consists of the following major phases:

1. Download and stage the required patches.
2. Upgrade the OPatch utility to the latest supported version.
3. Validate Oracle Inventory and installed patch levels.
4. Perform prerequisite, conflict, and system space checks.
5. Run Cluster Verification Utility (CLUVFY) prechecks.
6. Execute OPatchAuto analysis to verify patch applicability.
7. Apply the Release Update using OPatchAuto.
8. Apply the JDK Bundle Patch.
9. Apply the OJVM Release Update.
10. Execute SQL patching (Datapatch) where applicable.
11. Validate the installation and verify the new patch levels.

This structured approach minimizes the risk of failures and provides a repeatable process for applying quarterly Release Updates to Oracle Restart environments.

Patch Information

Patch 39036936 — GI Release Update 19.31.0.0.260421 (REL-APR2026)
The Oracle Grid Infrastructure patches are cumulative and include the database CPU program security content.
The GI Release Update 19.31.0.0.260421 includes updates for both the Oracle Grid Infrastructure home and Oracle Database home that can be applied in a rolling fashion.
This patch is Oracle Data Guard Standby-First Installable.
The database subpatch includes the JDK fixes released in the prior cycle and will update the JDK in the Oracle home. For the most recent JDK fixes, a separate patch is available and needs to be installed in addition to this patch.

Patch Installation Pre-requisites

1. Download and Unzip the Patch

> Download the patch, stage the patches and unzip them to a location /u01/oracle/patches/RU_Apr2026. This directory must be empty and cannot be /tmp.

Patch Installation using OPatchAuto

> The OPatch utility has automated the patch application for the Oracle Grid Infrastructure (Grid) home and the Oracle RAC database homes. It operates by querying existing configurations and automating the steps required for patching each Oracle database home of same version and the Grid home.

> The utility must be executed by an operating system (OS) user with root privileges.

> Depending on command line options specified, one invocation of OPatchAuto can patch the Grid home, Oracle RAC database homes, or both Grid and Oracle RAC database homes of the same Oracle release version as the patch. You can also roll back the patch with the same selectivity.

Execution of scheduler jobs while database patching is running may lead to failures and/or performance issues.
There are jobs currently running or scheduled to be executed during next hour.
If you experience Datapatch errors caused by locking in the database, consider patching the database when jobs are not running or preventing jobs from starting.
To check for jobs that are running or scheduled to run:
SELECT owner as schema_name, job_name, state, next_run_date
FROM sys.all_scheduler_jobs
WHERE state = ‘RUNNING’
UNION
SELECT owner as schema_name, job_name, state, next_run_date
FROM sys.all_scheduler_jobs
WHERE state = ‘SCHEDULED’
and cast(next_run_date as date) > sysdate
and cast(next_run_date as date) < sysdate + 1/24;
