Efficient ArcServer Cache Management with a Staging Server

Getting a cache built can sometimes be a challenge but caching an ArcServer map service can be important if you want your web apps to display fast. Depending on the subject of your cache and what scales you cache at you can end up with tens or hundreds of gigabytes of data.

Cache tiles

In my office we cache both vector and imagery data for an entire county. We have 20 aerial mosaic data sets dating back to 1937 and several vector data sets that also cover the entire county. Caching all of this can put a real strain on a server and takes up limited server resources that can cause the server to perform poorly.

I’ve found that the best solution is to cache on a staging server and then transfer the cached tiles to a prepared production server. Here is how you can easily do the same:

  1. Create a service on your staging server.
  2. Set up caching in the Services Properties dialog.
  3. Create a service on your production server that has the same name as your staged service.
  4. Set up caching in the Services Properties dialog. From the “Tiling Scheme” drop down select “An existing cached map / image service” and navigate to the staging service. This will import all of your cache advanced setting that you defined on your staging service like scale levels.
  5. Run the Manage Map Server Cache Tiles tool to create the staged cache.
  6. Now you just want to copy your level folder (L00, L01, L02…) located in \arcgisserver\directories\arcgiscache\[your map service name]\_alllayers to the same location on your production server.

At this point your production server should have a full working cache. If you have a cache service that will need to be updated regularly you could even script the whole process and schedule it to run at night or on the weekend.
