How to Upgrade OPatch for Oracle WebLogic Server
Keeping OPatch up to date in Oracle WebLogic Server is crucial for applying patches, security fixes, and bug resolutions. The latest OPatch version ensures compatibility with WebLogic Server patches and helps avoid issues during patching.
In this guide, we will walk you through how to upgrade OPatch in WebLogic Server using the opatch_generic.jar method.
Step 1: Check Your Current OPatch Version
Before upgrading, verify the existing OPatch version with:
$ $ORACLE_HOME/OPatch/opatch version
📌 Example Output:
OPatch Version: 13.9.4.2.5
OUI Version: 13.9.4.2.0
💡 If your OPatch version is outdated, proceed with the upgrade.
Step 2: Download the Latest OPatch for WebLogic Server
1️⃣ Log in to My Oracle Support (MOS)
2️⃣ Go to “Patches & Updates”
3️⃣ Search for Patch 6880880
4️⃣ Download the OPatch version 13.9.4.2.11 (or latest) for your platform
Step 3: Backup the Existing OPatch Directory
Before replacing OPatch, create a backup of the current OPatch folder to prevent data loss:
$ mv $ORACLE_HOME/OPatch $ORACLE_HOME/OPatch_backup
Step 4: Install the New OPatch Version
1️⃣ Navigate to your patch download location:
$ cd <PATCH_HOME>/6880880
2️⃣ Run the OPatch installer in silent mode:
$ java -jar <PATCH_HOME>/6880880/opatch_generic.jar -silent oracle_home=$ORACLE_HOME
🔹 This will automatically extract and install the new OPatch version in the correct directory.
Step 5: Verify the New OPatch Version

$ $ORACLE_HOME/OPatch/opatch version
📌 Example Output (Latest Version):
