Server Specification

Server Architecture Overview

CenterView is built on a single Java-based architecture i.e. it is not made up of several products with different architectures bolted together. There are two main elements in the server architecture:

• CenterView Application Server - The CenterView application server is a Java-based application which runs within an Apache Tomcat container. CenterView supports installation on all the major hardware architectures and operating systems. Existing installations use Solaris, Linux and Windows based servers.

• Database Server - CenterView uses any major JDBC compliant database to store both configuration data and the results of analysis on data collected from other systems. Existing installations currently use either Oracle or Microsoft SQL Server.

Figure 1 shows the most typical deployment of CenterView in which the application server and database server run on separate machines, however, for small proof of concept installations a single server may be used to host both the application and database servers.

Typical Server Sizes

The following are typical server sizes for small, medium and large installations. For large installations we recommend that you engage a CenterView consultant to verify requirements and analyse data volumes to be processed and retained within CenterView. Please note, that backup/recovery capacity is excluded in these sizing estimates.

1       Note that the disk space on the applications server is sized assuming that there may be files placed on the server disk for CenterView to read. If no files are to be placed on the application server (e.g. CenterView will read files from an existing location) then only a small disk is required for the operating system and CenterView application software.

2       Note that these figures indicate the amount of database disk storage required which scales with the amount of raw and result data configured to be retained by CenterView. Some implementations with a high number of daily records but which only maintain problematic data may require less space than this.

Database Server Disk Configuration

For medium and large implementations the database should be configured for high performance throughput. In particular database performance is significantly affected by the way that the database server disks are configured. Organisations requiring this size of server will generally have their own database administrators who are familiar with this level of planning, however, for clarity the following shows recommendations when setting up a medium installation:
