Answer 1

The easiest way to diagnose any GeoRaster problems is to use sdo_geor.validateGeoraster and take advantage of the java GeoRasterViewer. The GeoRasterViewer (or GeoRasterTool) is specifically designed for usage by DBA and application developers and it doesn't require any special (or extra) setup or configuration to display any GeoRaster object.
can you do the following?
(1) connect to database and run, for example
SELECT t.georid, sdo_geor.validategeoraster(t.georaster) isvalid from georaster_table t order by georid;
(2) run the client-side Java GeoRasterViewer (or GeoRasterTool) to display the image you loaded.
Once the above is done and everything looks good, you can start working on MapViewer for web delivery, etc. unless you started with MapBuilder to do all the loading work and configurations.
hope this helps,
