I agree that would be useful. At the moment, these restarts are done
manually as needed, and the process is not run on a cron. We hope to get
4.5 on our test server very soon (today), and if the test phase goes
well, then we will not need to restart on a regular basis.
How long is the test phase going to last? Will it give users adequate
time to test out the new capabilities?
In the meantime, I would strongly suggest that users check the http
response status codes and handle those appropriately. For example, if
the response code indicates that the server is temporarily unavailable,
have the script sleep for a minute or two and try again (these restart
periods should be negligible in duration, so the sleep probably does not
need to be more than a minute). Not only will this immediately make
scripts more reliable, it's the way any web enabled client or script
should approach http communications (best practices kind of thing).

For users who want to know about the status codes, please see:

If users need help, we'd be happy to advise them where we can. Remember,
we are not operational (the UCAR network is not even considered
operational), and users will encounter more than a status code of 200.
Please let me know when you have this working in the IDV. ;-)

2) IDV Users, part 1: Everything should be back to how it was prior to
last Friday. However, we will need to restart the TDS a few times each
day, and this will result in thredds.ucar.edu being unavailable for
short windows of time (things usually bounce within 2-3 minutes). If you
notice that a collection has stopped updating, please let us know via
email to support-thredds@xxxxxxxxxxxxxxxx.
Could you please post the times that you will be restarting the TDS so
that we can adjust our automatically updating bundles and cron scripts
to not hit the server at those times.
Thanks.
Don
