Answer
The ArcGIS 9.2 file-based geodatabase, also called file geodatabase, is supported in ArcIMS 9.2 only by way of the ArcIMS ArcMap Server.
Data from a file geodatabase cannot be used in an ArcIMS image or feature service, but relative data can be added in ArcGIS ArcMap. The .mxd is published as an ArcIMS ArcMap image service.
