I have feature class with 70,000+ records (file geodatabase). 
I want to make in bulk update on an attribute where the value is NULL.
Select by attribute shows that I have 5,000 records like that. Doing it one by one is going to be a pain.

In sql pseudo code it should be something like that:

 UPDATE &lt;MyAttributeName&gt; = 'NewValue'
 WHERE &lt;MyAttributeName&gt; IS NULL


How do I do that with ArcMap 10.1?


Question: MapServer MapCache WMS
Answer: You have installed two separate programs:
- MapServer that is a map engine
- MapCache that is a tile cache for rendered images
With your request you hit Mapserver (by using a peculiar Mapserver specific "browse" mode). The MapCache service will be found from another URL http://server/mapcache/? as you can see by reading the documentation http://mapserver.org/mapcache/index.html
You will need to read the documentation in any case because you must configure Mapcache to read maps from the Mapserver side before you can make the whole factory to run.
