Installing or Updating OVO Software
Automatically
This section describes how to install or update OVO software
automatically using the installation script.
Before You Begin
Before you install or update OVO, you need to understand how to work
with the installation script, root passwords, and managed nodes.
About the Installation Script
When you install, update, or de-install OVO software, you use
functionality provided by the OVO administrator GUI, as well as the
inst.sh(1M) script.
To avoid the verbose output of this script, you can set a shell variable for
the user root:
Bourne/Korn OPC_SILENT=1; export OPC_SILENT
C setenv OPC_SILENT
About Root Passwords
Before you can begin software maintenance, you need to know either the
root passwords of the managed nodes, or you must make.rhosts entries
available for user root (UNIX only). Failing that, make sure the local
/etc/hosts.equiv (on the UNIX managed nodes) contains an entry for
the management server.
About Managed Nodes
Before installing or de-installing OVO software on the managed nodes,
read the section “Installation Tips” on page 43.
IMPORTANT Make sure you have either REXEC, RSHD or SSH services enabled on the
remote agent (DCE or HTTPS-based) before you start the OVO agent
installation. Otherwise the agent installation will fail.
