Summary:
If you have Cicode in your project that opens the Alarm Event Queue via the AlarmEventQue Cicode function then you may experience problems opening it when running in Multi-Process mode

Solution:

When running in Multi-Process mode, the AlarmEventQue Cicode function can only be called by the Alarm Server process. By default, any Cicode that is initiated by the user (e.g. called via a button) will be executed on the Client process. You can easily change this by setting your alarm processing Cicode function as your Startup Cicode function for the Alarm Server Process in the Computer Setup Wizard:

This will set [Alarm.<Cluster Name>.<Alarm Server Name>]StartupCode parameter in your citect.ini file.
