Layers not visible to REST

ar4 — Wed, 15 Jun 2011 13:52:56 GMT

I have a mxd map published as a service serving KML . The service is consumed in google earth.

The map has 64 layers and all of them are visible in the GE client and ArcMap.

However when I go to the REST service only 19 layers are visible.

I get the same results using the SOAP service . Nothing I can see can make these layers appear.

I thought I might have a zoom or scale visibility problem but the rest service shows the same 19 layers when I use the URL http://server/ArcGIS/rest/service/layers

Can anyone enlighten me as to what setting or function might make layers invisible to the REST and SOAP APIs ?

Did you look at the ArcGIS Server Manager log?

Only certain types of layers are supported and the ones which have problems are logged.

I turned up the logging to verbose and made all columns visible.

I ran both a SOAP service test and tried the REST URL http://server/ArcGIS/rest/service/layers .

I did not see any errors. For the SOAP calls ( which included a find ) I did see the find initiation and the searches against the visible layers.

However the "missing" layers are still missing .

Is the a listing in the documentation of what layer types are supported somewhere ? Will "unsupported" layer types always throw an error ?

I will keep testing

No errors thrown from either the REST layers URL or the SOAP calls but no mention of the missing layers.

I opened the map in arc map , As far as i can tell the missing layers and the visible layers are the same , the "visible check box " is checked and the types are the same .

Ok some more info

I opened the log files manually it told me there was a error of type 4013 when the server object is created . The error lists the missing layers but declares them to be invalid.

We tried changing or reentering the data connections but this did not effect the layer "validity".

However all the layers are visible in the KML service we are publishing are visible and they are coming from the same map file and the same DB.

Is there anyway to have the logs tell us why a particular layer is invalid ?

MSD or MXD based map service?

MXD
10.0 setup with Java server and Oracle DB

Ok I have determined that the reason for the layers not appearing is that that are "invalid".

I have been able to configure a test map which produces "Unable to init from %s" and "Layer x is invalid ".

However these are the errors in the verbose ( and info:detailed) log . Is the any way to get more detail on these errors ?

for example -->WHY<--- the service is "Unable to init from %s"?

As you confirmed, I knew that server logged the invalid layers.

I also know that MSD has tighter restrictions but you are using MXD.

Additional suggestions:

If the the layer is coming from SDE then make sure that you saved your credentials when you created the connection in ArcCatalog. Server has no UI to collect these from you.

Look at the problem layers in ArcMap and see if you can find the problem. In fact, you might try logging on the system using the ArcSOC account and then view the MXD in ArcMap.

Thanks for the suggestions

I have been using ArcMap and ArcCatalog .

I have already noted a frustrating condition where I have to correct data connections in BOTH to make the "Invalid Layer" Message disappear.

However having done that, the service will not publish and throws a "Unable to init from %s" error.

Strangely all the data is visible in ArcMap.

I really need the Arcmanager to give a much more useful error message. Is there really no way to "dial up" the error message verbosity to a significant level ?

Goggle for: "Unable to init from" arcgis server

One of the reasons that I suggested that you literally run ArcMap using the ArcSOC account is due to various permission issues. For example, we put our map documents in \users\public because the ArcSOC account does not necessarily have access to other directories.

How to debug suggestions:

ArcGIS Server Manager log

ArcGIS Server REST log

Use the SysInternals DebugView utility, make sure that you Capture Global Win32

Debug using Visual Studio or WinDbg

Already googled..I have extensively checked and rechecked permissions ( the listed cause in the results ) and in any case there was no result that matched the search term.

Most people appear to be getting a file reference in the error message, I get %s.

Arc Sever Manager log - While it let me know an error occurred it does tell for what or why . Mostly unhelpful even at the highest detail levels.

REST admin - since the service will not create this is unavailable. Unsure if this is expected behavior.

I am using the Java server but ill look to see if the other steps are helpful. I did dig down to the stderr file and find that the stack trace reporting that the error occurring in calling what appear to be C functions in server creation process.

What I really need in the ability to turn the serve logs upto TRACE or DEBUG levels .

However this seems to be a rather laborious process for large map documents . For "invalid layers" especially so where a map might contain 50-100 layers .
