Download AutoUpgrade

As I described already in AutoUpgrade Patching – From Zero to Hero – Part 1: Download AutoUpgrade, you have several ways to fetch the newest version of AutoUpgrade – and when you use it to download patches, it will automatically trigger an update with the newest tool by downloading it.

Another quick way is this:

curl -L -O https://download.oracle.com/otn-pub/otn_software/autoupgrade.jar

But please, check out Download AutoUpgrade and choose your best way.

Version Change

When you call AutoUpgrade with the -version option, it should tell you then:

java -jar patches/autoupgrade.jar -version

build.version 26.6.260925
build.date 2026/09/25 22:11:20 +0000
build.hash e53aa37a5
build.hash_date 2026/09/25 18:13:12 +0000
build.supported_target_versions 12.2,18,19,21,23,26
build.type production
build.label (HEAD, tag: v26.6, origin/stable_devel, stable_devel)
build.MOS_NOTE KB123450
build.MOS_LINK https://support.oracle.com/support/?anchorId=&kmContentId=2485457

Amazing Enhancements in the newest 26.6 version of AutoUpgrade

You know it already. It is so much more than just an “upgrade” tool. It patches your databases, it finds and downloads the patches, it creates your Oracle – and so much more. Always use the newest – and the fixes and enhancements are certainly cumulative, meaning the 26.6 version has everything from the previous versions included.

What I like a lot is the new ability to download CPAT directly now with AutoUpgrade by using prefix.patch=CPAT in the config file. And of course, the ability to fetch Enterprise Manager patch bundles, too. And DBSAT. And SQLcl. Well, and you can also fetch the Exadata patches and the Grid Infrastructure Gold Images now with AutoUpgrade. Let me show a quick example config file for your convenience – and be aware that alone the EM patches are massive:

global.global_log_dir=/Users/mdietric/TEMP/AU/logs
global.keystore=/Users/mdietric/TEMP/AU/keystore
global.folder=/Users/mdietric/TEMP/AU/patches

patch1.patch=OEM:24.1
patch1.target_version=26

patch2.patch=OEM:13.5
patch2.target_version=26

patch3.patch=CPAT
patch3.target_version=19

patch4.patch=DBSAT
patch4.target_version=19

This will fetch the following bundles and tools:

java -jar autoupgrade.jar -config em.cfg -patch -mode download

Composer tools

I know that Marcus Vinicius has updated the AutoUpgrade Composer already. And not sure if you are aware, but Kamil Stawiarski has launched ALIS, too 🙂

• ALIS – AutoUpgrade config file composer (Kamil Stawiarski)
• AutoUpgrade Composer (Marcus Vinicius)

So, in case you struggle with creating your own config file, the two tools will help you for sure in getting started.
