ArcGIS Server, ArcGIS Online - Questions, Answers, and Resources

ArcGIS Server Services

  • Should we use fewer Services with more layers or more services with fewer layers?
    • From an application performance perspective.
    • From a server demand perspective.
      Is server demand currently an issue?
       
  • Should we use dedicated services with everything an application needs or general services that can be used by many applications or both?
     
  • How many services are too many and is that likely to be an actual problem for us in the foreseeable future?
     
  • Is there any advantage to separating the services that run our applications from services we are sharing?
     
  • What data are we, and should we be, sharing through services?
     
  • What can we do to increase the efficiency of our services?
     
  • What kind monitoring can we set up?
     
  • What testing can we do?
     
  • Should we move some of our data and services to the State server or ArcGIS Online?

ArcGIS Server Caching

  • How are our current caches set up?
     
  • What is being cached?
     
  • How will they be used?
     
  • What else do we want to cache?
     
  • For what layers do we want to build caches and for what do we cache dynamically?
     
  • Can we do a combination of predefined caching?
    i.e.  Build a cache to a certain scale then cache dynamically beyond that.  Or, cache the most likely layer combinations and dynamically cash the less likely combinations.
     
  • Does it make sense to cache small simple layers like IDFG Regions beyond the most general zoom levels?
     
  • How many and how large cached services can we support?

ArcGIS Online

  • What do we have on there now?
     
  • Where do the data, services, application code actually reside?
     
  • What are we likely to use it for in the future?
     
  • Who will be the “Named Users”?
     
  • How many named users do we want to license?
     
  • Should we move some of our data and services to the State server or ArcGIS Online?
     
  • Do we want to upload data, create services, build caches, now while it’s free? Will they delete everything and make us start over.

Permissions to ArcServer?

Do I need special permissions to publish a map to ArcServer?  When I try to do so, I get an error message "must have an administrative connection".  I have a connection to the server via ArcCatalog - I don't know that it is an 'administrative connection though.  I created this support ticket as a placeholder-I know Tuesdays are busy for you so when you get a chance later in the week please look at this.

Thanks :-)

 

Preventing Schema Locks in ArcSDE from ArcGIS Server 10.1.

By default, ArcGIS Server creates a schema lock on all layers and tables in a Map Service while the service is running.  This will prevent adding or deleting fields or records. 

At 10.1 this and a lot of other admin tasks can be done directly on the rest endpoint as described below.

By default, ArcGIS Server map services use schema locking to prevent other users from altering the geodatabase schema while the service is running. If the schema locks are impeding your workflow, you can disable them by using the ArcGIS Server Administrator Directory.

To disable schema locking for a service, perform the following steps:

  1. Navigate to http://<server name>:6080/arcgis/admin.
  2. Click services.
  3. Click the service for which you want to disable schema locking.
  4. Click edit.
  5. Add the “schemaLockingEnabled” = “false” property within the service JSON, as in the following example:

    …………………………………………………..

    “maxImageHeight”: “2048”,

    “schemaLockingEnabled”: “false”,

    “maxRecordCount”: “1000”,

    …………………………………………………..

Resource to check your maps and webpages for the color-blind

Are you a red means "Stop" and green mean "Go" kind of person?  You might want to rethink this approach for cartography.

Here's an example of just how poorly your maps may translate for the color-blind.

So before pressing print, save an image and run it through some software to see how it translates to those with Deuteronopia, Protanopia and Tritanopia:

  • Vischeck lets you upload images to their server to view with various kinds of colorblindness.
  • Color Oracle installs on Windows, Mac and Linux for local processing on large files.

Don't forget the real world too... ask around and find coworkers who can evaluate your maps before publishing.
