Since the alternatives settings could change for various reasons, it could cause some problems to PKI.

When "yum install pki-ca" is entered, will the Dogtag installer switch automatically, report a clean and nice error, or will it crash? If 'alternatives' does not update to the latest java "automatically", and perhaps even if it does, this ticket proposes considering circumventing its use by hard-wiring PKI paths to Java 1. For Ubuntu use update-alternatives.

After you install the rpm, you can check: alternatives --display java to see if you can see the new version is controlled by alternative, if not you need to "--install" them; otherwise, I think you can just skip "--install" part.

Question feed. I have Ubuntu You have to do this for other jdk components too. These components are appletviewer , extcheck , idlj , jar , jarsigner , java , javac , javadoc , javah , javap , javaws , jconsole , jdb , jexec , jhat , jinfo , jmap , jps , jrunscript , jsadebugd , jstack , jstat , jstatd , keytool , mozilla-javaplugin.

For further information, you can see the man pages for update-alternatives : man update-alternatives. The command update-java-alternatives sets alternatives for java components and it seems to use update-alternatives for this.

Note: update-java-alternatives won't work with manual installations. In any case, it doesn't look like it has any special abilities which update-alternatives doesn't have, except convenience. As a graphical alternative to AnwarShah's command-line method, consider using Gnome Alternatives sudo apt-get install galternatives :.

I actually use these commands to install jdk1. Check the link below for updated complete update-alternatives script. You can get more help by using the command man update-alternatives or you can see the manual in your browser here. I use this script to to extract a downloaded jdk, and use update-alternatives to fully set it.

Initially, Oracle decided to be able to have several versions of Java installed, based on setting some environment variables. It was easy, but too complex for those who didn't know those variables, and somebody invented "update-java-alternatives". The problem is that this solution is too complex to configure, if you have to configure yourself you have to configure it for each and every command of java.

In my case this was, even easier Update : as newur says in comments, just use sdkman. Made another slightly different script to default all java related stuff to a manually installed JDK:. It is not as complicated as the other answers make it out to be. You have to add the manual installed java to the alternatives list, then switch to is: replace jdk1. So, to get it to work with my manual installation: copy jdk1.

But at least we have a file to work with. I put what air-dex and Anwar said in a script. I know test30 also wrote a script but it was too complicated for me a scripting novice to understand. I just thought I'd post it here in case somebody might find it useful. You would want to replace jdk1.

Note : You need update-alternatives only if you have multiple java versions. Some of java related links are at master level and cannot be used as slave in update-alternatives --install.

Used the following commands to install oracle jdk and update alternatives. Hope it helps. Ubuntu Community Ask! Sign up to join this community. The best answers are voted up and rise to the top.
