Re: CSS/Phoebus installation questions

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Folks,

I was able to get Phoebus 6.0.0 running on Windows.  I just installed the Microsoft build of OpenJDK 25, and then the phoebus.bat file just worked. 

https://learn.microsoft.com/en-us/java/openjdk/download 

I also got Phoebus 6.0.0 running on Linux with OpenJDK 21 using these commands:

sudo dnf install java-21-openjdk-devel

sudo update-alternatives --config java

sudo update-alternatives --config javac

The latter 2 commands select which version of the JDK is selected.

Hi Mark

You can certainly use your own JDK, version 22 or for the next release, 25. Kay had been including the JDK in the SNS specific packaged versions for convenience. I don’t know offhand what his generic build includes and I am away from the office for a bit so it is not easy for me to check. I do know that the “nightly” build  is not currently nightly, though.

Folks,

I am trying to install Phoebus on Windows.  When I go to ORNL site (https://controlssoftware.sns.ornl.gov/css_phoebus/) it says this:

1. For Linux, install Java. Suggested is the current one from Open JDK. For Windows or Mac OS X, Java is included in the `phoebus...zip`.
2. Download the `phoebus-*.zip` for your architecture

I downloaded the nightly build from August 11, 2026 and extracted it.  It contains this directory:

phoebus-4.7.4-SNAPSHOT

That surprises me, I would have thought it should be a 5.x or 6.x release?

This is the contents of that directory:

 Directory of C:\Users\rivers\Downloads\phoebus-win\phoebus-4.7.4-SNAPSHOT

               7 File(s)         79,030 bytes

               4 Dir(s)  195,588,313,088 bytes free

I don't see a JDK there, but the instructions say that Java is included in the phoebus...zip file.

Am I missing something?

I also tried downloading the latest 6.0.0 .zip file form Github.  That contains the directory

product-6.0.0 

That directory contains:

Directory of C:\Users\rivers\Downloads\phoebus-win-6.0.0\product-6.0.0

10/13/2026  11:55 AM    <DIR>          .

               5 File(s)         13,910 bytes

               4 Dir(s)  194,714,386,432 bytes free

That also does not contain a JDK.

Is the recommendation to install from Github and then install the JDK separately?

Thanks,

Mark
