System Attributes

Select View ➔ System ➔ System Attributes menu item

A system attribute is a configurable value which can be used to customize the IRIS system. Each attribute has a corresponding type: string, boolean, integer or floating point number.

String values are limited to 64 characters or less
Boolean values must be specified as either true or false
Numeric attributes can be constrained to a minimum and maximum bound, depending on the attribute.

When a system attribute has been modified from its default value, it will be displayed in bold on the System Attributes form.

Most attribute changes take effect immediately, but some require the IRIS client or server to be restarted.
