24SEVEN Version 2.6 CAD Services — Overview <br />CompuDyne Proprietary <br />0 1. UNDERSTANDING THE PROCESS <br />The 24SEVEN CAD Services consist of two major components in the process: the Queue Processor and <br />a 24Seven CAD Adapter. Currently, 24SEVEN has two different available CAD adapters: the Web <br />Service Adapter and SQL Adapter. The CAD Services Administrator allows monitoring of the message <br />queues, and performs other setup features. <br />The basic process for the 24SEVEN CAD Services is very simple. One of two 24SEVEN adapters <br />receives a CAD message, and places the message into the Queue Processor's message queue. The Queue <br />Processor monitors the queue, processes the message and inserts the message into the proper tables in the <br />24SEVEN RMS database. If the Queue Processor cannot process the message or finds invalid data, it <br />stores the message as far along in the process as possible, and writes an error to the Windows Event Log. <br />1.1 QUEUE PROCESSOR <br />The Queue Processor is required for any CAD Services installation of the 24Seven RMS software. It is a <br />Windows service, which needs to launch on the Windows server for the process to work. The Queue <br />Processor does just what its name says; it monitors the private 24Seven MSMQ for CAD messages and <br />processes the messages sending the information to the 24SEVEN application. <br />The Queue Processor has two separate MSMQ Queues associated with it. The first is the Cad24Seven <br />queue where the CAD messages route from either of the 24Seven CAD Adapters. The second is a <br />recovery queue, which is a part of the error catching system for CAD messages to ensure their delivery. <br />• CAD software can choose to send to any one of the three - 24SEVEN CAD adapters, but you will only <br />need to use one of them. We recommend the Web Service Adapter for the greatest flexibility, and <br />performance. <br />0 <br />1.2 WEB SERVICE ADAPTER <br />The Web Service Adapter is an XML Web Service that receives an XML message, and places the <br />message into the Queue Processor's Message Queue for processing. It is the preferred way to send <br />messages to the 24SEVEN CAD Services. <br />1.3 SQL ADAPTER <br />The SQL Adapter is a Windows Service that monitors a set of CAD SQL Server Tables. The SQL <br />Adapter processes rows in the tables, and generates an XML Message from the rows and sends them to <br />Queue Processor message queue for processing. The SQL Adapter interacts with a defined set of Stored <br />Procedures to allow a CAD developer the greatest flexibility in the process. <br />1.4 FILE ADAPTER <br />The File Adapter is a Windows Service that monitors a directory for two specific fixed position format <br />files. The File Adapter processes files, generates an XML Message from the records, and sends them to <br />the Queue Processor message queue for processing. The File Adapter is configured by using the <br />fixedfile.xml file, and that defines which fixed file values are placed into the RMS. <br />CompuDyne Proprietary <br />CompuDyne December 28, 2005 Page 1 <br />
