Installing Java 8 on the Resource Manager master host
This procedure installs Java 8 alongside Java 6 on a Resource Manager master host. Resource Manager version 4.2.x requires Java 6, and this release of the Service Impact server requires Java 8.
- Log in to the Resource Manager master host as root, or as a user with superuser privileges.
- Download the RPM file of latest Oracle Java SE Runtime Environment (8u121 or later) from the Java SE 8 Downloads page.
Install the Java 8 package, except the jexec utility. Replace
Package_name as necessary.
rpm -ivh --excludepath /etc/init.d/jexec Package_name.rpmThe Service Impact server does not use the jexec utility, so the Java 6 version can remain in place.
Set the default version for Resource Manager to Java 6.
For Resource Manager version 4.2.4:
rm /usr/java/default ln -s /usr/java/jre1.6.0_31/ /usr/java/default
For Resource Manager version 4.2.5:
rm /usr/java/default ln -s /usr/java/jre1.6.0_45/ /usr/java/default
Create a link to Java 8 for the Service Impact server, replacing
Version with the version of the package you installed.
ln -s /usr/java/jre1.Version /usr/java/zenoss_impact
