====== ArcGIS ======
Using ArcGIS on the cluster to execute GIS tasks is based on using the embedded Python shell for ArcGIS Server 10.1 and you have paid to use the Esri software at UD. A single seat includes all Esri products that UD licenses for all architectures. See [[http://sites.udel.edu/gis/software/esri-licensing/|UD GIS Esri licensing]] for complete details. Each user must install the ArcGIS shell in their own account before running an interactive or batch job on a cluster.
===== Install ArcGIS shell =====
Each user must install the embedded Python shell for ArcGIS Server 10.1 in their own account on the cluster. It only needs to be done one time and must be done on a compute node. It requires approximately 2GB of storage, so make sure you choose a directory location with sufficient storage available such as your workgroup storage (''$WORKDIR/$USER'') for the installation.
Please be patient. The installation may take up to 5 minutes to complete.
The basics steps are
* Define your ''workgroup''
* Connect to a compute node using ''qlogin''
* Run the install script ''/opt/shared/arcgis/bin/install-arcgis-10.1 ''
* ''exit'' the compute node after the installation is complete
Installing the ArcGIS shell only needs to be done once for your account and it will only work for your account! However, you will need to [[:software:arcgis:arcgis#update-arcgis-shell-license|update the license]] annually when the [[:software:arcgis:arcgis#errorlicense-expired|license expires]].
This information is based on the [[:software:arcgis:procedural_install|installation procedure]] documented for ArcGIS on a Linux cluster.
===== Update ArcGIS shell License =====
Each year the Esri license is updated for ArcGIS products, so you will need to update your ArcGIS shell installation with the updated license file too. You can do this by using the following command (all on one line) by replacing '''' with the name of the directory location you provided when you installed your ArcGIS shell such as your workgroup storage (''$WORKDIR/$USER'').
/arcgis/server/tools/authorizeSoftware /opt/shared/arcgis/data/10.1/ArcGISforServerAdvancedEnterprise_server.prvc
===== Troubleshooting =====
==== Not running X-Windows ====
=== ImportError: DLL load failed: DLL init failed ===
The example below shows the error you get when you try to run the ArcGIS shell during an interactive job without an X-Windows server running. In this case, ''import arcpy'' cannot load successfully. You must run an [[arcgis#running-x-windows-and-display-set-properly|X-windows server like Xming with the DISPLAY set properly]] or ''unset DISPLAY'' before you run the ArcGIS shell as explained in the next section.

=== unset DISPLAY ===
The example below shows the ''LIBGL'' error you get when you ''unset DISPLAY'' before running the ArcGIS shell during an interactive job without an X-Windows server running. This error will likely appear in the .o file for a batch job. In both cases, this error can be ignored because the ArcGIS shell does not use a GUI and ''import arcpy'' does load successfully.

Although it is not obvious, the error shown below is what you get when you try to ''import arcpy'' if the license has expired for your ArcGIS shell installation. You will need to [[:software:arcgis:arcgis#update-arcgis-shell-license | update your ArcGIS shell license]] to fix this problem.
