Configuring Action Request System server for CAI

BMC Helix ITSM uses Command Automation Interface (CAI) to integrate with backend applications, such as the BMC Helix ITSM: Service Desk:Incident Management feature of BMC Helix ITSM: Service Desk and BMC Helix ITSM: Change Management. CAI is a subcomponent that is used to run commands on external systems. CAI uses a command definition (a type of template) to construct commands by using the parameters sent to it by BMC Helix ITSM. CAI then uses a predefined conduit (for example, a web service, a command line, a URL) to execute the command. The installer also registers the plug-in path, which is added to the beginning of the existing path.

By default, CAI uses the fast and list server queues from AR System, which can have a detrimental effect on performance in high-volume installations. However, to improve performance, you can generate a private server queue for CAI to exclusively use for its processing. This option takes pressure off the queues and assists with improving performance.
