Does IBM i ACS need JAVA? Nope.

ACS, Semeru

“Does IBM Access Client Solutions need Java to work?”

One of my clients asked me this earlier today

Nope.

IBM i ACS does NOT need Java to work!

Not strictly speaking – since we can use The IBM Semeru Runtimes instead of Java.

Oracle owns Java. There are many alternatives to Java – some branched from earlier public versions of Java and some written from the ground up.

IBM have their own version of one of these branches and it’s called IBM Semeru.

The IBM Semeru Runtime Open Edition has an open source license (GPLv2+Classpath extension). The only binary JDK distribution that gives you free access to OpenJDK class libraries powered by the Eclipse OpenJ9 JVM.

It’s free. It replaces Java. Sounds Good?

Let’s install it.

First a quick overview of IBM i ACS:

Since IBM i ACS was released back in 2018, this new IBM i connectivity application has caused much scratching of heads. IBM i ACS was created to replace the old Windows suite called Client Access. Personally I think this yet another naming gaff from IBM – access client solutions is too similar to client access and easily confuses people that are unsure of what these application does.

IBM i ACS is supported on Java 8 or higher. Of course, IBM recommend using the current Java Long Term Support (LTS) version.

Since Oracle, changed the licensing rules for Java this caused quite a stir in the industry. Java is Free for personal use – But for commercial use Java 11 and above is available from Oracle under a commercial support agreement. The Java Oracle license change has raised concerns because support costs are expected to rise.

Companies are obviously concerned about this – so what are the alternatives?
