Installing CA Spectrum in a Distributed Environment

Distributed Installation Requirements
Ensure that you meet the following requirements before you start a distributed installation:
  • Check the Release Informationabout any new parameters that are required for the Host Installation Information file.
  • Establish a TCP/IP connection from the target system to remote systems.
    In firewall environments, ensure that port 46517 is opened during a distributed installation.
  • Verify that the time setting on the installer host is synchronized to within 2 minutes of the time setting on the remote hosts. This setting is required for secure authentication with the
    Remote Administration Daemon.
  • Verify that the remote hosts have sufficient disk space. The
    distributed installation copies temporary files to temporary directories on the target system. Therefore, it requires at least 100 MB of disk space in the temp or tmp directories. For Windows, you can edit the default TEMP location as a user Environment Variable.
Types of Distributed Installations
lets you select the type of distributed installation that meets your requirements.
The following table shows the available types of distributed installations and their corresponding procedures found in this section:
Type of Distributed Installation
installation on Solaris or Linux
from 9.0 or later on Linux or Solaris
installation on Windows Server 2008 or Windows Server 2012
from 9.0 or later on supported Windows platforms
How to Perform a Distributed Installation
distributed installation is a command line interface that lets you install
and the OneClick web server (locally and remotely). Different types of installations can be performed on each system. For example, you can install the following items in a single distributed installation:
  • SpectroSERVER
  • OneClick web server only
  • SpectroSERVER
    and OneClick web server
distributed installation has the following components:
  • Remote Administration (SRAdmin) Daemon
    Allows for secure, remote installations without requiring that you manually set up the NFS mounts or Microsoft Network File shares. A time-critical Triple-DES encryption is used to ensure that the root/Administrator account/password information is safe when it is passed between daemons. Install SRAdmin on each remote system where you install
  • Distributed Installation Client (sdicsol.exe for Solaris, sdiclinux.exe for Linux, and sdicnt.exe for Windows)
    Launches multiple installations across multiple machines and collects the results of these installations. The distributed installation client requires the following files:
    • Password file
      Contains accounts and passwords for remote computers.
    • Host installation file
      Contains installation information. The topic HII File Parameters contains important information about the required contents of this file.
