Hi Peoples, I installed ArcGIS Server 10.3 Pre-release, which ships with Tomcat 7.0.54. The problem is still there. More noticeable in Firefox. Does not appear so much in Chrome or IE. I shall document, report to support, and if I find anything, post to let people know the outcome. Out of the box, ArcGIS Server uses the HTTP connector (not the AJP), so this is why people are probably not seeing this as an issue. Our ICT staff are keen to continue using AJP (but alas they may have to change). Cheers, Mark

Hi Peoples, We have had difficulties connecting to ArcGIS Online through ArcMap, and now specifically in relation to obtaining a license for ArcGIS Pro. It has come to our attention that SQUID Proxy does not allow ArcGIS connections on the default port. I am attempting to find out more information in relation to this issue. Has anyone else seen this, and have additional information? Cheers, Mark

Hi Peoples, For what it is worth, when we attempted to upgrade from 10.1 to 10.2, it went badly. Badly to the point of restore from backup. It looks like we will do a clean install, then rebuild the site. Beware the even number release - odd ones always seem better. Bring on 10.3 Cheers, Mark

Hi Peoples, With the pre-release version of ArcGIS Pro, it appears one has to connect to ArcGIS Online as a named user to authorise a license. Is this license model the future plan for ArcGIS Pro? If this is the plan, I can see a few problems. For a start, it takes us about two hours before ArcGIS Pro finally makes this connection. It is most likely due to our reverse proxies. If or when we do connect (it also fails at times), we can check a license out, but this is not optimal. While we generally have around 25 licenses on our FlexLM license manager active at a time, there are probably around 50 or 60 people that use it, many on a casual basis. With named users on ArcGIS Online, this is going to cause us more administration and hassle factor. Is this license model going to change the cost/license structure of an ELA? Cheers, Mark

Hi Peoples, Has anyone else seen issues with ArcGIS Server 10.2.2, specifically in relation to load balancers and cached image services that appear to be missing tiles when returned via REST? A quick summary of our architecture. We have two instances of ArcGIS Server 10.2.2 running. We have a load balancer in the DMZ that is configured to communicate with ArcGIS server via our reverse proxies through AJP. We are using cached image services for our base maps, which include an aerial photo layer, topographic base map, and scanned images of our topographic map series. The Problem: If we connect directly to the REST end points of our ArcGIS Servers, and view in ArcGIS JavaScript, the services work fine. No problem. If we connect via the Load Balancer to the REST end point, as we zoom in and pan around, tiles are missing. If we turn Fiddler on, we obtain a Protocol Violation Report, with Content-Length mismatch errors. We did not see this in ArcGIS Server 10.1. Further investigation Looking further into this, we discovered the content-length header is extremely important. If it is present and non-zero, the container assumes that the request has a body (a POST request, for example), and immediately reads a separate packet off the input stream to get that body. There appears to be a bug fix for a security flaw in the 7.0.47 release of Tomcat specifically to do with the Content-Length. It could be a coincidence, but ArcGIS Server 10.2.2 ships with Tomcat 7.0.47, while 10.1 ships with 7.0.27. This issue seems to be specific to the AJP protocol. If we swap to using HTTP, the issue seems to be fixed. We could do this, but that is going to cause us some grief with DMZ, fire walls, existing systems etc. We think this is due to the version of Tomcat that ships with ArcGIS Server 10.2.2. Anyone else seen this? Anyone know which version of Tomcat 10.3 ships with?

Hi Peoples, Came across this bug in 10.2.2 the other day. Posting this so if others come across it they will know the work around. Summary: Spatial reference incorrectly set for image services with WMS capabilities, when Image has Web Mercator Auxiliary Sphere as projection. Problem did not exist in 10.1. How to Reproduce: Take any image that has the projection : WGS_1984_Web_Mercator_Auxiliary_Sphere : WKID: 3857 Copy the image to a folder that has been registered as a Data Store with ArcGIS Server. Open ArcCatalog, navigate to the image, right click and share as Image Service. Publish as Service Service Editor > Capabilities > Enable WMS Publish the service with default settings Open the ArcGIS REST endpoint for the image service Select the WMS link, and check the GetCapabilities for the WMS service. URL will be something like: http://<your server>:6080/arcgis/services/Raster/TestWMSAux/ImageServer/WMSServer?request=GetCapabilities&service=WMS Note the CRS statement: <CRS>CRS:84</CRS> <CRS>EPSG:4326</CRS> <CRS>EPSG:0</CRS> NOTE the CRS is set to EPSG:0 This is incorrect. It should be set to EPSG:3857, which is the projection of the original data. In ArcGIS 10.1 this is correct. By default, WMS services only list two spatial reference systems; EPSG:4326 (or CSR:84 for WMS 1.3.0) and the spatial reference of the map service that WMS is enabled on. http://resources.arcgis.com/en/help/main/10.1/index.html#//015400000596000000 It would appear the CRS is not being picked up for the image, and thus being set to 0. This has the effect the image cannot be added as a WMS service in projection 3857. Work Around: Change the WMS service property: Additional spatial reference systems Use Manager or ArcCatalog to add the projection to the WMS service properties manually. This will fix the problem. Additional reference: http://resources.arcgis.com/en/help/main/10.1/index.html#//00sq000000m1000000 Cheers, Mark

This has been recorded as a bug: #NIM104376: The JSON response of a cached image service shows wrong 'minPixelSize' and 'maxPixelSize' values in ArcGIS Server 10.2.2 Although a bug, not sure if third party apps are relying on this information too much, so probably not a big issue. Also seems to be for cached image services. Cheers, Mark

Hi Peoples, We have installed ArcGIS Server 10.2.2 on our test instance, and just found the minPixelSize and maxPixelSize have been reversed in the JSON REST. This is a cached image service. Our 10.1.1 image service is here, and is correct: http://services.thelist.tas.gov.au/arcgis/rest/services/Basemaps/Topographic/ImageServer?f=pjson "minPixelSize": 0.5971642835598172, "maxPixelSize": 9783.93962049996, On our current TEST server, ArcGIS 10.2.2, this is the same service: "minPixelSize": 9783.93962049996, "maxPixelSize": 0.5971642835598172, Note this is incorrect. Has anyone else seen this? Is it a known issue? Our initial tests would indicate some third party apps rely on this, and it is going to be an issue. Cheers, mark

Hi Gary, Thanks - that answers the question well. This means I will now have to consider an ArcSDE 10.1 upgrade as part of the Delivery Server upgrade- something that is going to take a lot more planning and testing. Cheers, Mark

Hi Peoples, Do I need ArcSDE 10.2.2 to be able to serve an ArcGIS Server feature service that can be taken Offline and edited in Collector? If not, what is the minimum ArcSDE version that supports Collector Offline edit / sync ? Cheers, Mark

Hi Raymond, I made the story map with the Map Tour Builder. I found the web map that was created as part of this process, and altered the basemap as you suggested, and it worked. Thanks for the solution. Cheers, Mark

Hi Peoples, I created a Story Map with the Map Tour App. The basemaps button allows me to choose a basemap from the esri selection, but does not allow me to choose one from a URL, or from my organisation. How can I choose a basemap other than esri? Cheers, Mark
