Using Oracle JDK under CentOS

Mon 26 November 2012 by Lars Kellogg-Stedman

I needed to replace the native OpenJDK based Java VM with the Oracle Java distribution on one of our CentOS servers. In order to do it cleanly I wanted to set up the alternatives system to handle it, but it took a while to figure out the exact syntax.

For the record (and because I will probably forget):

alternatives --install /usr/bin/java java /usr/java/latest/bin/java 2000 \
  --slave /usr/bin/keytool keytool /usr/java/latest/bin/keytool \
  --slave /usr/bin/rmiregistry rmiregistry /usr/java/latest/bin/rmiregistry
