Stop search for updates in GPT

snap
#1

Hi,

When I start a process in GPT, by default it seems SNAP is searching for new updates. Since I am woring behind a proxy, the connection is not established resulting in a Time Out error. This step is introducing some delays on my processing chains, so I am wondering if it would be possible to disable it somewhere in the GPT options?

P.S.: I plan to install updates manually when they become available

You can add the following property to to the gpt.vmoptions file.
-Dsnap.versionCheck.interval=NEVER
Then it is disabled for all gpt calls.
Alternatively, you can set the property for each call by adding it to your gpt command line call.
