Notes from the field: XenMobile Location services and SQL deadlocks

Came across a pretty specific issue in a large mobility environment regarding an old value from XenMobile 9 and still present in XenMobile 10, this is called device triangulation, with this the mobile service provider can triangulate the exact location from the device with constant updates regarding there location (this was an old value which was used with SMG and not applicable anymore).
This can cause significant impact on your database server with deadlocks.

The solution is to look for the following value:
Enable Device Triangulation
zdm.device.triangulation.enable
Preffered value: false
Default value: true

This won’t change application actions regarding geofencing because those are application and container specific.

Besides the above there is also an global value optional regarding location services in combination with iOS devices (the annoying popup you’ll get when enrolling the device which security people always ask you about 🙂 the following article will explain the values for XenMobile 9 and XenMobile 10: https://support.citrix.com/article/CTX137614

Thanks to Arnaud Pain for going into more detail regarding location services client side, take a look at his blog: http://arnaudpain.com/index.php/2017/02/06/xenmobile-disable-location-service/
