Prerequisites for Linux and Solaris
Ensure that you meet the following prerequisites before you install 
 on a Linux system or a Solaris system.
  • Root Privileges
 and 
 Remote Administration (SRAdmin) Daemon installations require root privileges to evaluate available resources and run custom installation scripts. Installing under the root ensures root privileges for the setuid executable, which lets the 
SpectroSERVER
 connect to SNMP ports. Because an initial installation generates residual files with root ownership, subsequent upgrade installations also require root privileges.
  • Fixed IP Address
Ensure that the system on which you plan to install 
 has a fixed IP address. You can enable DHCP on the system when the DHCP server issues a static address that never changes.
  • Hosts File
Ensure that the /etc/hosts file has the following format:
  • 127.0.0.1 localhost localhost.localdomain <external IP> <external names>
    • external IP
      Is the static DNS IP of the host.
    • external names
      Are the DNS short names.
Make sure that the first line has the local host after the loop-back address. The loop-back line must have localhost as the official host name.
You can add nicknames after the local host. For example:
  • 127.0.0.1 localhost localhost.localdomain
The following example is incorrect and would cause host resolution and security problems with 
:
  • 127.0.0.1 <external name> localhost localhost.localdomain
  • NFS-Mounted File Systems
For 
 install directories that are an NFS-mounted file system, we recommend that you set the NFS mount options to ‘hard’ and ‘nointr’. These settings help ensure database consistency.
However, as there are many possible problems with such a setup, including severe performance impacts, we recommend that you avoid NFS mounts, if possible.
If you 
do
 use the 'hard' and 'nointr' NFS mount options, take extra care to obtain good database backups.
We do not recommend the 'soft' option at any time.
  • Set Up CDE Style Manager (Solaris 10 Only)
Before you install 
, set up the CDE Style Manager to ensure proper behavior of OneClick views.
Follow these steps:
    1. From CDE, select the Desktop Control button.
    2. In the Application Manager - Desktop Controls window, select Window Style Manager.
    3. Select Allow Primary Windows On Top.
      This option allows pop-up windows to appear on top of OneClick views.
    4. Within the Application Manager - Desktop Controls window, select Color Style Manager.
    5. Select Raise Window When Made Active to allow a partially blocked window to appear on top when active.
      The CDE style manager is set up.
  • Solaris ZFS Snapshots
One of the final steps of the 
 installation on Solaris platforms is the execution of the chown -R command. This command gives ownership of the 
 installation to the installation owner.
If you have taken a ZFS snapshot of your 
 installation, ZFS creates a .zfs directory in the <
$SPECROOT
> directory. This directory can cause massive delays during the installation process when the chown -R command is run.
To prevent massive delays during the installation process, the Administrator must hide the zpool snap directory before installing 
. To hide this directory, enter the following command:
  • zfs set snapdir=hidden prod/data
    This command does not affect the data that is stored; it makes the data invisible to the 
     installation. The Administrator can reveal the zpool snap directory after the installation completes.
