Oracle 23ai Patch 39093711 Upgrade Guide: Apply Database Release Update 23.26.2.0.0

Oracle AI Database 23ai continues to redefine enterprise database management with advanced automation, AI capabilities, and modernized infrastructure. To maintain security, optimize performance, and ensure platform stability, applying quarterly Release Updates is critical. In this guide, we’ll walk through the complete process of upgrading Oracle Database 23ai to Release Update 23.26.2.0.0 using Patch 39093711 in a RAC environment.

Why Upgrade to Oracle 23ai RU 23.26.2?

Oracle’s Patch 39093711 delivers:

September 24, 2026

Oracle Database MRP 19.32.0.0.260915: Patch 39971265 Installation Guide

September 18, 2026

Critical security fixes
Performance improvements
Oracle AI Database feature stability
Updated JDK and Python components
Enhanced RAC compatibility
Bug fixes for enterprise workloads

For organizations running Oracle AI Database 23ai in production, staying current with Release Updates is essential for minimizing vulnerabilities and ensuring Oracle support compliance.

Step 1: Verify OPatch Version

Oracle recommends OPatch version 12.2.0.1.49 or later. How To Download And Install The Latest OPatch

Validation:

$ opatch version
OPatch Version: 12.2.0.1.51

Using the latest OPatch version reduces installation risks and supports Oracle 23ai RU requirements.

Step 2: Run Conflict Checks

Before patching Oracle Home, validate for patch conflicts:

$ opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/patch/39088031/39093711

Result:

Prereq "checkConflictAgainstOHWithDetail" passed.

This confirms Patch 39093711 is compatible with the existing Oracle Home.

Step 3: Apply Patch 39093711

After shutting down all Oracle instances for the target ORACLE_HOME, run:

$ opatch apply

[oracle@rac-node1 39093711]$ /u01/app/oracle/product/23.26.0.0/dbhome_1/OPatch/opatch apply

Patch 39093711 successfully applied.
Sub-set patch [38743669] has become inactive due to the application of a super-set patch [39093711].
Please refer to Doc ID 2161861.1 for any possible further required actions.
Log file location: /u01/app/oracle/product/23.26.0.0/dbhome_1/cfgtoollogs/opatch/opatch2026-05-04_13-45-24PM_1.log

OPatch succeeded.

Patch process includes:

Oracle Home backup
Component validation
Binary patching
JDK upgrades
Python updates
RAC environment patch preparation

Successful output:

Patch 39093711 successfully applied.

Oracle automatically deactivates prior subset patch 38743669, replacing it with the new superseding Release Update.

Step 4: Validate Post-Patch Binary Installation

After installation:

$ opatch lspatches
39093711;Database Release Update : 23.26.2.0.0 (39093711)
38743688;OCW RELEASE UPDATE 23.26.1.0.0 (GOLD IMAGE) (38743688) Gold Image

This confirms Oracle Home binaries are fully upgraded.

Step 5: Run Datapatch Sanity Checks

Before SQL patching, validate database readiness:

$ datapatch -sanity_checks

SQL Patching sanity checks completed on Mon 04 May 2026 02:09:18 PM +0530

Important Findings from Sanity Checks

Warnings Identified:

1. SSH RAC Node Communication Failure

Warning: SSH connection between nodes failed

This limits some remote validation checks but does not always block patching.

2. Dictionary Statistics Outdated

EXEC DBMS_STATS.GATHER_DICTIONARY_STATS;
EXEC DBMS_SYSTEM.GATHER_FIXED_OBJECTS_STATS;

Refreshing dictionary statistics helps avoid post-upgrade performance issues.

3. Recycle Bin Objects Detected

PURGE RECYCLEBIN;

Recycle bin cleanup is highly recommended before datapatch execution.

Step 6: Prepare for Datapatch

Ensure:

RAC node SSH is functional
Recycle bin is purged
Dictionary statistics are current
All PDBs are properly opened
No invalid objects or tablespace issues exist

Oracle 23ai 23.26.2 Benefits

After successful patching, organizations gain:

Security:

Updated vulnerability protections
Improved encryption support
Hardened Oracle Home

Performance:

JDK and Python enhancements
AI feature stability
Improved RAC behavior
Better patch supersedence management

Operational:

Reduced software risk
Enhanced Oracle support alignment
Improved patch lifecycle consistency

Best Practices for Oracle 23ai Patching

Recommended DBA checklist:

Upgrade OPatch first
Run prerequisite conflict checks
Validate RAC SSH connectivity
Gather dictionary stats
Purge recycle bin
Execute datapatch sanity checks
Monitor logs carefully

Common Oracle 23ai Patch Challenges

Watch for:

OPatch version mismatches
RAC SSH failures
Recycle bin blockers
Closed PDBs
Outdated dictionary statistics
Insufficient Oracle Home space

Proactive validation significantly reduces production patch risks.

Final Thoughts

Oracle Database 23ai Patch 39093711 (RU 23.26.2.0.0) is a critical upgrade for enterprise RAC environments seeking improved security, performance, and AI platform reliability.

This real-world patching process demonstrates that successful Oracle 23ai maintenance depends on:

Proper OPatch versioning
Thorough prerequisite validation
Clean Oracle Home preparation
Datapatch readiness
RAC environment consistency

For DBAs managing Oracle AI Database platforms, quarterly patching remains one of the most important strategies for protecting enterprise infrastructure while maximizing database innovation.

Oracle 23ai patching is more than routine maintenance—it’s strategic operational resilience.
