Chapter 3 - System Components Please note that Inform CAD Queue displays can affect bandwidth and the frequency of updates and bandwidth consumption. This would include countdown timers (time since status change) and the like. Please consider your bandwidth when enabling new features that will affect the frequency of Citrix updates. Large Sites with complex mapping displays particularly with Geo may require additional bandwidth beyond 128Kbps. 12.5INFORM CAD CITRIX SERVER CONFIGURATION 12.5.1 STANDARD INFORM CITRIX SERVER TriTech recommends only one level of server for Citrix utilization for Inform CAD. This recommendation has evolved from previous recommendations based upon more information from testing in TriTech's lab as well as operations at customer sites. The approved Citrix Server supports 8-12 Inform workstations for small to medium size sites. Large Sites should adjust the number of workstations down to (typically to 5-8) and test the configuration before implementing or increase the server processor/memory. 12.6 INFORM CAD CITRIX SERVERS AND UPGRADES During an upgrade of CAD software (versions, service pack and patches), all users have to exit from that specific CAD Citrix server in order for the upgrade prerequisites to take effect, and run "TriTech.Launch" from the desktop of the Citrix server to pull down new software components from the database server. Sites should plan for sufficient server capacity to allow for continued operation during an upgrade. This can be in the form of additional production Citrix servers or the ability to re -point a test/training Citrix server on a temporary basis to production. Sites with a single Citrix server will need to plan for some downtime during an upgrade. 12.7 INFORM CAD CITRIX SERVERS AND SEPARATE ENVIRONMENTS CAD Citrix servers can only operate on a single environment — that is, a CAD Citrix server can be on the production system or the test/training system, but not both at the same time. The Multi -Environment selector does not work with Citrix servers as the CAD users on a Citrix server are effectively sharing the same software and connections to a single environment. Therefore clients should plan for separate Citrix servers for test/training and disaster recovery. 12.8 INFORM CAD CITRIX WORKSTATION Citrix workstations should generally be the same hardware specifications as the standard for the same version of Inform CAD with the following differences: 1. Citrix workstation needs to be added to the Machine _Info table of the System database. 2. Citrix workstations do not require Inform CAD Prerequisites from the Prerequisite CD. 3. Citrix workstations do not require Power User windows permissions. They should have the permissions necessary for them to interact with the Citrix server.
