Large dataset upload and download
There is a file size limitation for uploading data capability when sharing a web tool and downloading output data when running the web tool. The limitation depends on the heap size of the federated server that hosts the web tool. The default server heap size is 64 MB; however, the size can be modified by the server administrator if needed. Check with your server administrator to increase the heap size in the following instances:
- Uploading raster data larger than 64 MB
- Uploading feature data close to or larger than 64 MB
- Downloading feature data close to or larger than 64 MB
When downloading large feature data, the maximum number of records returned by the server should also be considered. The default record size is 1000. If the number of records returned will be larger than 1000, you can do the following:
- Reset the maximum record count from the web tool settings when sharing as a web tool.
- If you do not reset during the sharing process, the data will not be downloaded, and the web tool execution results in the geoprocessing history contains the message data exceeds transfer limit. You will need to log in to the federated server manager and reset the maximum number of the geoprocessing service that hosts the web tool,
For detailed explanations about the relationship of heap size and large upload and download datasets, see Large dataset upload and download consideration of ArcGIS Desktop. From ArcGIS Desktop, you can change the maximum number of records returned from the server connection. You cannot do the same from the ArcGIS Pro Project pane, as there is no administration permission for all the services under the server connection in ArcGIS Pro.
Use custom geographic transformation
There are occasions when you may want to use a custom geographic transformation file (.gtf) for the web tool you share. If this is the case, ensure that the .gtf file is on the federated server that hosts the web tool. For more information on creating a .gtf file and saving it to the server, see Use geoprocessing services with custom geographic transformation. The .gtf file path saved in ArcGIS Pro is similar to that in ArcGIS Desktop. You can just replace the Desktop10.x part of the .gtf path with ArcGISPro.
