Oracle Database 19.32 Release Update (RU) is the latest quarterly patch for Oracle 19c, providing important security fixes, bug fixes, and stability improvements. If you have a standalone Oracle Client installation (without a database), patching is straightforward because datapatch is not required.

In this article, I’ll demonstrate how to upgrade an Oracle 19c Client from 19.31 RU to 19.32 RU.

---

Environment

Component	Version
Operating System	Linux
Oracle Client	19c
Current RU	19.31 (39034528)
Target RU	19.32 (39472050)
Oracle Home	/u01/app/oracle/client_1
OPatch Before	12.2.0.1.51
OPatch After	12.2.0.1.52

---

Step 1 – Set the Oracle Client Environment

Source your Oracle Client environment.

. .setenv_client

Example environment file:

export ORACLE_BASE=/u01/app/oracle/
export ORACLE_HOME=/u01/app/oracle/client_1
export PATH=$PATH:$ORACLE_HOME/bin
export PATH=$PATH:/u01/app/oracle/product/GG

Verify the environment.

echo $ORACLE_HOME

Output

/u01/app/oracle/client_1

---

Step 2 – Check Existing OPatch Version

Navigate to the OPatch directory.

cd $ORACLE_HOME/OPatch

Check the installed OPatch version.

./opatch version

Output before update:

OPatch Version: 12.2.0.1.51

---

Step 3 – Verify Current Patch Level

List the currently installed patches.

./opatch lspatches

Output

39034528; Database Release Update : 19.31.0.0.260421

This confirms the Oracle Client is currently running 19.31 RU.

---

Step 4 – Update OPatch (Recommended)

Oracle recommends using the latest OPatch version before applying Release Updates.

After updating OPatch:

./opatch version

Output

OPatch Version: 12.2.0.1.52

---

Step 5 – Apply Oracle 19.32 Release Update

Navigate to the extracted patch directory.

cd /path_to_patch/39472050

Run OPatch.

$ORACLE_HOME/OPatch/opatch apply

During execution OPatch performs:

• Environment verification
• Inventory validation
• Prerequisite checks
• Oracle Home backup
• Patch application

You will be prompted to continue.

Answer

y

If Oracle processes are still using this Oracle Home, OPatch displays:

Please shutdown Oracle instances running out of this ORACLE_HOME

Since this is an Oracle Client installation, simply ensure that no applications are using the Oracle Client libraries before proceeding.

---

Step 6 – Patch Installation

OPatch patches the Oracle Client components.

Patch 39472050 successfully applied.
Sub-set patch [39034528] has become inactive due to the application of a super-set patch [39472050].
Please refer to Doc ID 2161861.1 for any possible further required actions.
Log file location: /u01/app/oracle/client_1/cfgtoollogs/opatch/opatch2026-07-28_14-45-39PM_1.log

OPatch succeeded.

OPatch also reports:

Sub-set patch [39034528] has become inactive due to the application of a super-set patch [39472050].

This is normal behavior.

Each Release Update supersedes the previous one.

Step 7 – Verify the Patch

After completion, verify the installed patch.

$ORACLE_HOME/OPatch/opatch lspatches

Output

39472050; Database Release Update : 19.32.0.0.260721

The Oracle Client is now successfully upgraded to 19.32 Release Update.

Before vs After

Item	Before	After
Oracle RU	19.31	19.32
Patch Number	39034528	39472050
OPatch	12.2.0.1.51	12.2.0.1.52

---

Important Notes

• Oracle Client patching does not require datapatch because there is no database dictionary to update.
• Ensure all applications using the Oracle Client (SQL*Plus, GoldenGate, application services, etc.) are stopped before patching.
• Always update OPatch to the latest supported version before applying a Release Update.
• Verify the patch installation using opatch lspatches.
• Keep a backup of the Oracle Home or ensure a rollback strategy is available before patching.

Conclusion

Upgrading the Oracle 19c Client from 19.31 RU to 19.32 RU is a simple OPatch-based process. By updating OPatch first, validating the existing patch level, applying the 19.32 Release Update, and verifying the results with opatch lspatches, you can keep your Oracle Client environment secure and aligned with Oracle’s latest quarterly maintenance.

Since this is a client-only installation, there is no need to execute datapatch, making the overall patching process faster and simpler than patching an Oracle Database Home.
