HP SVA V2.1 System Administration Guide

1 Managing Configuration Data Files
This chapter describes the Configuration Data Files. It includes the format and content of the
files, as well as how to change the files.
1.1 Format and Content of Configuration Data Files
This section describes the general format and content of the Configuration Data Files:
• Site Configuration File.
• User Configuration File.
• Job Settings File.
The Configuration Data Files contain information on the configuration of the SVA. Visualization
applications that run in a distributed way on the cluster need this configuration information,
notably when launching a visualization job. The Site Configuration File contains information
on the configuration of the SVA, including the site-specific arrangement of display devices. If
the configuration of the SVA changes, you must change the Site Configuration File.
You can use the Configuration Data Access functions, which work in conjunction with the
Configuration Data Files, in the job launch scripts and in a visualization application. The functions
get system configuration information and can put values that are used as part of the visualization
job execution. The Configuration Data Functions are documented in the SVA Visualization System
Software Reference Guide.
Refer to the SVA User's Guide for an overview of the Configuration Data Files and the job launch
scripts. The scripts provide good examples of how you can use the Configuration Data Access
functions.
1.1.1 Site Configuration File Definition
When you receive your cluster from HP, it has already been assembled. The Site Configuration
File is defined based on the physical configuration of the cluster and its nodes, including the
node roles (render node versus display node). Many of the Site Configuration File settings are
static and are unlikely to change. Some of these settings can be customized by user preferences
and individual jobs.
If you physically add or remove nodes from the cluster, you must update the Site Configuration
File. This is a system administrator or HP Field Service task that uses a cluster discovery process.
See Section 1.2 for details on how to change the Site Configuration File.
1.1.2 File Format
Data files are flat text files arranged in section names and populated by associated pairs of tags
and tag values.
1.1.2.1 Comments
A pound character (#) at the beginning of a line denotes a comment. The line is ignored unless
it is within a quoted value.
1.1.2.2 Section Names
Sections divide data files into areas that share related purposes. Sections have the following
characteristics:
• Section names are case sensitive.
• Section names are enclosed in brackets without spaces. The left bracket must be in column
one.
