Installing Oracle Analytics Server (OAS) 2026 on my Windows

This is a practice installation of OAS 2026 on my unsupported Windows 11 Laptop. Usually, I prefer a Linux installation for practical purposes, yet I also do a practice one on my laptop.

The download page is here, or the edelivery site here. If you use edelivery, don't forget the Java Developers Kit 21. In 21 the JRE is included in JDK. 

After installing JDK, you should have at least the 2 jar files (3 on Linux):

This is the installation guide here.

The basic steps:

• Install JDK 21 if needed
• Install fmw 14.1.2.0.0
• Install Oracle Analytics Server 2026
• Configure Oracle Analytics Server 2026

The short version:

• Download and install JDK from here. I prefer installing in a folder without spaces in the name like c:\JAVA and not the default C:\Program Files\.... that has spaces.
• Install fmw 14.1.2.0.0  
• java.exe -jar fmw_14.1.2.0.0_infrastructure.jar
• Install OAS 2026 in the same Oracle Home 
• java.exe -jar Oracle_Analytics_Server_2026_Windows.jar
• Configure with RCU set up as separate step (as many prefer) or as part of the general Configure flow. (described here)
• RCU: ORACLE_HOME\oracle_common\bin\RCU.bat don't use the default option there (see below)
• Configure: ORACLE_HOME\bi\bin\config.cmd
• Download and configure the Remote Console from this Git

If you install the RCU on the supported Oracle 26ai, you might get "ERROR - RCU-6080 Global prerequisite check failed for the specified database". Check note KB876701 "Creating Repository Schemas for Oracle Analytics Server Errors With 'RCU-6080' " on support site for a patch or workaround.

The Longer version:

After installing JDK 21, I can install FMW. On Windows run CMD as Administrator.

c:\JAVA\jdk-21.0.10\bin\java.exe -jar fmw_14.1.2.0.0_infrastructure.jar

The installer UI starts

And you should set the Oracle_Home of the installation.

Mine was C:\Oracle\Ora_Home1

Next I install the OAS software 

    c:\JAVA\jdk-21.0.10\bin\java.exe -jar Oracle_Analytics_Server_2026_Windows.jar

in the same home.

You will get Visual C++ installation request

"Setup Failed" usually means this is installed already.

If you want to set RCU as a separate step, please note

The default option of "Oracle Database enabled for edition-based redefinition" doesn't let you select Analytics in the next screen  

The regular Oracle database as Database Type, works fine:

In my case I used the RCU creation as part of the OAS config and it worked fine. 

    ORACLE_HOME\bi\bin\config.cmd

You will see a welcome screen

Next you can select Analytics and Publisher

As Oracle recommends, I changed the Domain Home to a separate location, unlike the default.

Please note you have to create the folder in advance, or you will get the "Domain does not exist"error:

If you used the RCU utility, select to use existing Schemas

If not, create one now:

Next is the port range

And, if you have a previous jar file, you can use it as default.

Run 

In my case this was Successful.

In the past I had few cases when the config timed out on the startup phase. What solved the issue for me then was to startup manually the OAS services without closing the UI window and let the config continue. 

Don't forget to save all the link at the end:

When you try to Open Console, you will discover that you need to download and configure the Remote Console from this Git.

It looks a bit differant.

Let's do the basic task of adding users with the Remote Console.

On the left panel select the last option of Security Tree

 

Select Realms, next press myrealm

Now you can create users

And see them in OAS:
