every night, the Oracle/ArcSDE server gets restarted. As a result, some, but not all, map and GP services require a restart to be functional afterwards. Can others confirm this experience and share solutions?
at 10.0, when publishing a service, there was an option for the service to check for this sort of thing and repair itself, but this seems to have disappeared at 10.1.
failing and other feedback, we propose to automate the restart of all ArcGIS Server services after the nightly ArcSDE restart.
