FAQ: Why is my model broken after I install 9.0 Service Pack 2?

Question

Why is my model broken after I install 9.0 Service Pack 2?

Answer

If the model contains any of the following tools, such as CreateRasterCatalog, CreateRasterDataset, MosaicToNewRaster, or HotSpotsRendered, the model may have been broken because those tool signatures changed at ArcGIS 9.0 Service Pack 2.

The signature changes are as follows:

CreateRasterCatalog
The spatial reference parameter was changed from optional to required.

CreateRasterDataset
The spatial reference parameter was changed from optional to required.

MosaicToNewRaster
The order of the following parameters was changed: cellsize, pixel, pixel type, coordinate system for the raster.

HotSpotsRendered
A distance band or threashold distance parameter was added.

For more details on why models break and the methodology to repair them, see the Related Information section below.

Special care is needed with the 4 tools listed above. Their variables may have become disconnected and their parameter values may be have been cleared.
