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
