How to Apply Oracle 19c Patch 19.30 on Linux – Step-by-Step Guide

Keeping your Oracle Database 19c up to date is critical for security, performance, and stability. In this guide, you’ll learn how to apply the latest Oracle 19c Patch 19.30 on a Linux environment.

📌 Prerequisites

Before applying the Oracle 19c Patch 19.30, ensure:

• Oracle Home path is set correctly.
• The database is running.
• Backup of the database and Oracle Home is taken.
• Latest OPatch version (12.2.0.1.40 or higher) installed.
• Sufficient disk space available.

Step 1: Download the Required Patches

These two patches must be downloaded from Oracle Support:

• Oracle 19.30 Database RU Patch
• OJVM Patch (optional but recommended)

Current Database Version

In our case, we just install oracle 19c base version 19.3.0.0.0 only, and we will apply the latest patch on it.

Download OPatch Version

OPatch utility version 12.2.0.1.48 or later to apply this patch. Download the OPatch latest version.

Update OPatch Version

Unzip the OPatch inside the Oracle home directory, but before it take backup of the old OPatch directory.

[oracle@ocptech dbhome_1]$ unzip p6880880_190000_Linux-x86-64.zip -d /u01/app/oracle/product/19.3.0/dbhome_1/ 

Check OPatch Version now:

[oracle@ocptech OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.49

OPatch succeeded.

Step 2: Prepare Patch Directory

mkdir -p /u01/patch-19.30
cd /u01/patch-19.30
unzip p38632161_190000_Linux-x86-64.zip .

Step 3: Stop Database and Listener

Stop all the database services using the following steps:

sqlplus / as sysdba
SHUTDOWN IMMEDIATE;
EXIT;
lsnrctl stop

Step 4: Check Current Patch Level

$ORACLE_HOME/OPatch/opatch lspatches


[oracle@ocptech ~]$ $ORACLE_HOME/OPatch/opatch lspatches
29585399;OCW RELEASE UPDATE 19.3.0.0.0 (29585399)
29517242;Database Release Update : 19.3.0.0.190416 (29517242)

OPatch succeeded.

Step 5: Run Conflict Check

[oracle@ocptech 38632161]$ pwd
/u01/patch-19.30/38632161


[oracle@ocptech 38632161]$ $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir .
