I just had a situation where I had to change the JAVA_HOME for my Oracle Unified Directory<\/a> (OUD) instance. Although this is quite simple, this blog post serves as my “sticky note”. <\/p>\n

During the setup of my OUD instance I’ve set the wrong JAVA_HOME. I’ve used JDK 1.8 instead recommended JRE 1.7. OUD does work well with Java 1.8, but it is just not a “certified configuration”. You never know which bug is coming next \ud83d\ude09 . Because my OUD Instance is used productive, I decided to change it back to JRE 1.7 Update 101. If you OUD server runs a couple of months, Java has to be updated regularly anyway due to vulnerabilities.<\/p>\n

The JVM and Java arguments for each command is specified in properties file, which is in the INSTANCE_DIR\/OUD\/config\/java.properties<\/code>. To adjust the JVM settings, the OUD Instance must of course be stopped. New setting will then be applied with dsjavaproperties<\/em>.<\/p>\n

First set the proper default Java Home. I will use JRE 1.7 Update 101.<\/p>\n
