After running the Build Raster Attribute Table tool, the attribute table of the raster will contain a field called Value representing the pixel value, and a field called Count representing how many pixels of that Value.  You can then use the following code to write these value to an output text file: lstRasters = arcpy.ListRasters("*") logfile = open(r"c:\temp\pixels.txt", "w") for raster in lstRasters:     rows = arcpy.SearchCursor(raster)     for row in rows:         logfile.write("Value of " + str(row.value) + " = " + str(row.count) + " pixels" + "\n") logfile.close() ...

I ran a test with this scenario.  I created a two-way replica from one sql server database to another.  I added the child geodatabase feature class to ArcMap, added a join, updated a field based off of the join, did not remove the join, and then executed the 'Export Data Changes Message' tool from the Distributed Geodatabase toolbar.  I was able to successfully create the XML file and import this into parent geodatabase.  So, the join/relate should not be affecting the replica.  What is the error message you are receiving? ...

What service pack are you running for SQL Server 2005?  You can run the following query to find out: SELECT  SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition') ... View more

Try building pyramids using a direct connection.  You will just need to replace '-i' with 'sde:sqlserver:<server name>.  Also, make sure you are attempting to build pyramids with the raster dataset owner (GIS_ADMIN).  I would also specify '-1' for the -L option.  This will build all necessary pyramid levels.  Ex: sderaster -o pyramid -l HRES_COLOR_MRSID_MOSAIC_2010,RASTER -v 1 -L -1 -I bilinear -D RASTER -i sde:sqlserver:<server name> -u GIS_ADMIN -p ***** ...

Not the most elegant way, but I got the below code working.  Could be cleaned up a bit. rows = arcpy.UpdateCursor(input) for row in rows:     Xcoord = str(row.X)     Xcoord2 = Xcoord.split(".")     XDegrees = Xcoord2[0]     Xcoord3 = float("." + Xcoord2[1])     Xcoord4 = Xcoord3 * 60     Xcoord5 = str(Xcoord4)     Xcoord6 = Xcoord5.split(".")     XMinutes = Xcoord6[0]     Xcoord7 = float("." + Xcoord6[1])     Xcoord8 = Xcoord7 * 60     Xcoord9 = str(Xcoord8)     XSeconds = Xcoord9     DMS = XDegrees + " " + XMinutes + "' " + XSeconds + "''"     row.Lat = DMS     rows.updateRow(row) del row, rows You can duplicate the code and run it for the Longitude value. ...

Pyramids will consume approximately 1/3 of the raster dataset size.  If this raster dataset is 24 GBs, you're looking at another 7.2 GBs in storage you'll need. I would recommend running the 'sp_spaceused' command in SQL Server Management Studio to see how much unallocated space is available.  If the tool is still executing, re-execute this query a couple times and see if the unallocated space is shrinking.  If it is, this means pyramids are still being generated. If it is not, it may be your log file is full.  You can check this by executing one of the queries below: EXEC sp_helpdb RASTER DBCC SQLPERF(logspace) ... View more

Try the following: import arcgisscripting gp = arcgisscripting.create(9.3) input = "<shapefile>" rows = gp.UpdateCursor(input) row = rows.Next() while row:     TimeList = row.Start_Time.split(":")     row.Hour = TimeList[0]     rows.UpdateRow(row)     row = rows.Next() del row, rows ... View more

Here is the code I got to work at 10.  You should be able to replace 'arcpy' with 'gp' and this should work at 9.3. input = "<table/feature class>" rows = arcpy.UpdateCursor(input) for row in rows:     TimeList = row.Start_Time.split(":")     row.Hour = TimeList[0]     rows.updateRow(row) del row, rows ...

Here is an example on how to do this.  You will need to replace 'arcpy' with 'gp'. input = "<table/feature class>" rows = arcpy.SearchCursor(input) for row in rows:     TimeList = row.Start_Time.split(":")     rows2 = arcpy.UpdateCursor(input)     for row2 in rows2:         row2.Hour = TimeList[0]         rows2.updateRow(row2) The field 'Hour' is of type Text. ...

Geocoding results are not dynamic since the output is a feature class.  The only type of outputs that are dynamic in this matter are event layers.  You will need to re-geocode the addresses after the updates have been applied and overwrite the feature class.  I would recommend running a script to do this at a given time(s) during the day. ...

You can only kill direct connections with the 'sdemon -o kill' command at version 10.  If you are at version 10, you will need to grant a couple other user permissions to the SDE user in order to kill direct connections: ALTER SYSTEM SELECT_CATALOG_ROLE http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/User_permissions_for_geodatabases_in_Oracle/002n0000002v000000/ If you are not at 10 you can still delete direct connections, but this must be done by deleting them through the 'sde.process_information' table.  I always recommend creating a database backup before editing/modifying any repository table. ...
