Chapter 1 -Overview and Forecast Since Inform CAD 5.3 the majority of server -based business functionalities such as Inform Communication Event Service (for CAD Monitor and Messaging), TriTech Web Services (like Driving Directions Web Service, and Document Web Service, etc.) are consolidated into service features hosted inside one or more VisiNet Service in Services windows services. Each hosted service feature (with the exception of Logging Service) can be configured through Inform Configuration Utility to run within one of the concurrently running VisiNet Service in Services windows services on -demand. / Inform 5.7 Workstation/Interface Prerequisite Changes —New versions of MSXML and net Framework will be utilized with Inform 5.7 workstations and interface applications. Carefully review the release notes and utilize the version specific prerequisite CO. Refer to Technical Advisory - GA08-020 - Inform CAD Prerequisite Installer. Inform CAD, since 4.5 and continuing with 5.7, sends error/debug/instruinentation log entries from workstations and servers to the Logging Service through MSMQ (Microsoft Message Queue). This provides asynchronous logging functionality for all Inform CAD applications, comparing to the legacy file -based logging. Logging Service collects and bulk insert all log entries into the Log database which can be queried for troubleshooting and reporting purposes. File -based logging is kept as an additional option which is turned off by default. 2.1.3 OTHER SYSTEM COMPONENTS Optional Business Servers (Citrix servers, Reporting Servers, Test/Training Servers, and the like) and Interface applications (NCIC/State Message Server, Paging, Station Alerting, and the like) are deployed based upon the operational needs of the customer. These are described in greater detail later in this document. An effective functioning Windows network is essential for optimal operation of an Inform CAD system. The components described in this document rely upon components such as domain controllers, DNS servers, properly functioning network switches, and properly configured Windows security settings. This document addresses these topics in order to prepare the customer's system administrator to effectively support their system. Customers routinely inquire about changes in hardware requirements between versions. TriTech's internal test systems are periodically refreshed with new hardware. This makes it difficult for TriTech to predict performance on older workstations and servers. TriTech's experience with upgrades in the 5.7 track has been that if the customer's existing equipment provides acceptable performance for Inform CAD, the next major version upgrade is not likely to significantly change performance unless the customer elects to activate new fimctionality or implements some other significant change (expanded workload, workstations, interfaces or OS/DB change). Nevertheless, TriTech will provide recommendations based upon the equipment with which TriTech tests. 2.2 OTHER NETWORK AND SERVER TECHNOLOGIES TriTech has approved the following technologies for use with Inform CAD: 1. Network Speed based on number of workstations and potential incident/AVL/Mail Volumes. If a customer satisfies ALL the following criteria, then 100MB network is sufficient The contents of this material are confidential and proprietary to TriTech Software Systems, Inc. and may not be reproduced, published or disclosed to others without the prior written consent of TriTech Software Systems, Inc. ©2015 TriTech Software Systems
