Prerequisites
Before starting the patching process, ensure you have:
- Oracle Database Client 19c installed
- Patch 39418910 downloaded from My Oracle Support
- Latest OPatch 12.2.0.1.52
- Administrator privileges
- Oracle applications (SQL Developer, TOAD, etc.) closed
- At least 8 GB of free disk space
- A backup of the Oracle Home directory (recommended)
Step 1: Extract the Release Update Patch
Download Patch 39418910 from My Oracle Support and extract it to a local directory.
Example location:
D:\client\p39418910_190000_MSWIN-x86-64\
After extraction, you’ll see the patch directory and setup files.

Step 2: Verify the Current OPatch Version
Before applying the Release Update, verify the installed OPatch version.
cd %ORACLE_HOME%\OPatch
opatch version
Example output:
OPatch Version: 12.2.0.1.15

Since Oracle recommends using the latest OPatch version, upgrade OPatch before applying the Release Update.
Step 3: Upgrade OPatch
Rename the existing OPatch directory.
Example:
OPatch
Rename to:
OPatch_old
Copy the new OPatch directory (Version 12.2.0.1.52) into your Oracle Home.

Step 4: Verify the New OPatch Version
Verify that the new OPatch version has been installed successfully.
cd %ORACLE_HOME%\OPatch
opatch version
Expected output:
OPatch Version: 12.2.0.1.52
OPatch succeeded.

Step 5: Check for Patch Conflicts
Navigate to the extracted patch directory.
cd D:\client\p39418910_190000_MSWIN-x86-64\39418910
Run the prerequisite conflict check.
D:\app\client\oracle\product\19.0.0\client_1\OPatch\opatch prereq CheckConflictAgainstOHWithDetail -ph ./
Expected output:
Prereq "checkConflictAgainstOHWithDetail" passed.
OPatch succeeded.
This confirms that the Release Update can be safely applied.
Step 6: Apply the Release Update
Apply the Release Update.
D:\app\client\oracle\product\19.0.0\client_1\OPatch\opatch apply
The installer performs several checks before patching:
- Oracle Home validation
- Inventory verification
- Backup of existing binaries
- Component dependency checks
- Release Update installation
When prompted:
Do you want to proceed? [y|n]
Enter:
y
Next prompt:
Is the local system ready for patching?
Enter:
y
The patch installation will begin.

Step 7: Patch Installation
During installation, Oracle updates many Oracle Client components, including:
- Oracle Net Client
- SQL*Plus
- RMAN
- OCI
- JDBC
- ODBC
- Java
- Oracle Wallet
- Oracle Networking
- Oracle Client libraries
Components that are not installed in the Oracle Home are automatically skipped.
After a few minutes, you should see:
Patch 39418910 successfully applied.
OPatch succeeded.

Step 8: Verify the Installed Patch
Verify that the Release Update has been installed successfully.
opatch lspatches
Expected output:

Windows Database Bundle Patch :
19.32.0.0.260721
(REL-JUL260721)
This confirms that Oracle Database Client has been successfully upgraded to Release Update 19.32.

Common Issue: Insufficient Disk Space
One of the most common issues during patching is insufficient free disk space.
Example error:
Prerequisite check "CheckSystemSpace" failed
Required amount of space (7586 MB) is not available.
OPatch failed with error code = 73
Solution
- Free at least 8 GB of disk space.
- Close applications using Oracle Home.
- Retry the patch.
Verify SQL*Plus
After patching, verify that SQL*Plus is still functioning correctly.
sqlplus -v
Example output:
SQL*Plus: Release 19.0.0.0.0
Best Practices
- Always back up the Oracle Home before patching.
- Upgrade OPatch before applying a Release Update.
- Run
CheckConflictAgainstOHWithDetailbefore patching. - Ensure no applications are using the Oracle Home.
- Keep a copy of the OPatch logs for future troubleshooting.
- Verify the installed Release Update using
opatch lspatches.
