It sounds like you may be setting up a weighted overlay with multiple layers if this is the case you should probably consider a consistent cell size for all of your layers and don't forget to use snap raster to avoid cell registration errors. So long as the cell sizes match, then the tool will not have to resample to normalize the data, which may be the issue you are describing. If you want to create excess perhaps buffering the original polygon some prior to conversion would help. This could give you plenty of room to clip against.

Depending on your polygon you can get better results with a smaller cell size. That may solve some of the 'saw tooth' issues you are having. Also be aware that if your line does not line up horizontally within a coordinate system that you will continue to have issues like this. They can be mitigated, but not eliminated. A more appropriate question is what are you trying to achieve with the conversion where they have to match up exactly.

Also be sure that when using the Image Analysis Window results, be sure to be zoomed into raster resolution. Due to the nature of Raster Functions, always compare with Source raster values.

For the point spacing, all you have to do is look at the properties of the LAS Dataset. Here is the help documentation. ArcGIS Help (10.2, 10.2.1, and 10.2.2) In terms of your error, I wouldn't be surprised if your file size is pretty large. I would consider trying to clip it down to estimate the size of the total export. The 999999 errors could be for a number of reasons, so I would just try to eliminate the possibilities. I would also recommend using the 3D Samples tool to export tiled rasters. The samples can be accessed at 3D Samples.

I think this has to do with the potential values in a float data range. Just like you cannot create an attribute table on a raster with 32 bit float bit depth. The number of potential rows that could be added are too high and the software will prevent you from doing this operation. When you turn the floating point values into an integer, then you can access it. Perhaps your database is preventing the error that would otherwise occur and forcing it into another field type. I haven't tested this, but the behavior is probably expected.

Your specific use case is exactly the case that an image service is built to handle, but I understand the budget frustration. I am not sure about the practicality of create multiple TB mosaics to try and publish or for that matter even create on your database. The raster catalog in Oracle is actually a managed raster catalog, where the data is ingested into the database, not linked to as with a file geodatabase, so any file created there will still be huge(imagery is imported into the database first). The question to answer is it cheaper to come up with a beefy database (SAN as Larry recommended) or otherwise or try to increase the budget for Image Server. If you only have internal customers, then you could potentially build the mosaic dataset on a network drive and then use the UNC paths to link to the data. All of your users will have to have access to the mosaic dataset, the source data and the overviews, but that will work internally. If you want to share it over the web then you are back to Image Server. Sorry for the hassle and I wish you luck with the budgeting discussion if that is the route you go.

I saw that statement about the 'any raster' statement and wonder if that should extend to 32 bit signed raster or is more specifically any 8 bit/16 bit multispectral raster. I have used 8 bit unsigned and 16 bit unsigned rasters with multiple bands and not seen that error. I have never tried a 32 bit signed raster until today. http://support.esri.com/en/ This is the address to login to your account and request a Support ticket. I would consider that route since they have the ability to log a bug report for you if this is judged to be a bug. Here on the forums, you can commiserate with other users and hopefully get someone on the Esri side to answer you, but through Support you will have your very own analyst to help you out.
