Installing Java 8 on the Service Impact server host

  1. Log in to the Resource Manager master host as zenoss.
  2. Stop Resource Manager.
  3. Log in to the Service Impact server host as root, or as a user with superuser privileges.
  4. Stop the Service Impact server, and then verify it is stopped.
    service zenoss_impact stop
    service zenoss_impact status
  5. Remove the Service Impact server package.
    rpm -e $(rpm -qa | grep zenoss_impact)
  6. If you are upgrading Service Impact on a remote host, remove Oracle Java, and then clean up the yum caches.
    rpm -e --nodeps $(rpm -qa | grep jre)
    yum clean all
  7. Install OpenJDK 1.8.
    • If you are upgrading the Service Impact server on its own, dedicated host, continue with this step.
    • If you are upgrading the Service Impact server on the Resource Manager master host, skip this step and proceed to the next section.
    1. Install the OpenJDK package.
      yum install java-1.8.0-openjdk.x86_64
    2. Verify the installation.
      java -version
      The result should be similar to the following example.
      java version "1.8.0_121"
      OpenJDK Runtime Environment (rhel- u121-b13)
      OpenJDK 64-Bit Server VM (build 24.121-b04, mixed mode)
