In this article, I'll walk you through the steps I used to
patch an Oracle Database 19c environment from version 19.29 to 19.31 following
Oracle's April 2026 Quarterly Release Update.
Quarterly patching is a regular responsibility for Oracle
DBAs, and while the version numbers may change, the underlying process remains
largely consistent across Oracle 19c Release Updates. This guide is intended to
serve as a practical reference that you can use during your own patching
activities.
Note: Never apply a patch directly to a Production
environment without first validating it in Development or Test. Thorough
testing helps identify potential issues before they impact business-critical
systems.
Requirements
Before proceeding, ensure that the following prerequisites
are met:
- Oracle
Database 19c (Windows x86-64)
- Active
My Oracle Support (MOS) account
- Appropriate
access to ORACLE_HOME and ORACLE_BASE directories
- Minimum
12 GB free disk space in Oracle Home
- WinSCP
or equivalent file transfer utility
- Scheduled
maintenance window and approved downtime
Step 1: Download the Patch and OPatch Utility
Log in to Oracle
Support and download the following:
- Patch
file: 38818049 → p38818049_190000_MSWIN-x86-64.zip
- OPatch
utility: 6880880 → p6880880_190000_MSWIN -x86-64.zip
Steps to download: Select Patches & Updates →
enter patch number → select platform Windows x86-64 → download
both files and review the README.
Step 2: Check and Update OPatch
On the server, check your current OPatch version:
|
cd
%ORACLE_HOME%/OPatch opatch
version |
You need version 12.2.0.1.48 or higher. If it's
older, update it:
|
cd
%ORACLE_HOME% ren OPatch
OPatch_backup1 robocopy
p6880880_190000_MSWIN -x86-64.zip %ORACLE_HOME% cd
%ORACLE_HOME% unzip
p6880880_190000_MSWIN -x86-64.zip |
Step 3: Run Pre-checks
Before applying the patch, check for conflicts with existing
patches:
|
C:\Users\Administrator>cd
C:\software\oracle_patch_19.31\38818049 C:\software\oracle_patch_19.31\38818049>D:\oracle\product\19.3.0\dbhome_1\OPatch\opatch

prereq "checkconflictagainstohwithdetail" Prereq
"checkConflictAgainstOHWithDetail" passed. OPatch
succeeded. |
As we see "OPatch succeeded", we are good to
go. If there are conflicts, resolve them before proceeding.
Step 4: Stop the Database and Listener
|
sqlplus / as
sysdba SQL>
shutdown immediate SQL> exit lsnrctl stop |
Verify all services are completely down before moving to the
next step.
Step 5: Clean Up Inactive Patches (Optional but
Recommended)
This frees up Oracle Home space before applying the new
patch:
|
cd
%ORACLE_HOME%/OPatch ./opatch util
listOrderedInactivePatches ./opatch util
deleteInactivePatches |
Step 6: Check Available Disk Space
Do not proceed if space is insufficient in oracle home
Step 7: Apply the Patch

Watch the output carefully. You should see success messages
for each component. The full process typically takes 20–30 minutes.
Sample successful output as above.
