NOBLE is pleased to announce the network will be upgrading to Evergreen release 3.10 in early January.
The upgrade will begin the night of Saturday, January 6. The system will be down from 6:00 p.m. Saturday until some time Sunday p.m. The system will be up and ready on Monday morning January 8.
Downtime Information
The extended outage for this upgrade is due to several factors:
- The postgres database will be upgraded from 9.6 to 10. This involves dumping the entire database to a file, installing the new version, and importing the data back into the database. These steps take 4-5 hours each.
- The operating system will also be updated which means that new application servers will be built.
- Database scripts that add new features to the database are standard for most upgrades.
What is affected when Evergreen is down:
- circulation and other staff functions
- authentication via SIP2 (Overdrive, selfcheck, Hoopla, museum pass, EZproxy etc.)
- web catalog
- patron services like placing holds and signing up for ecards
We had a phone call with MOBIUS, our Evergreen hosting provider, about minimizing the effects of the down time and came up with a few solutions:
- We will have a copy of the database put on a test system about a week before the upgrade. This can be used by staff to search for materials to get call numbers. We will send the URL to this system out the week before the upgrade.
- Mobius will point the SIP server to the test system. We will pull the recently added patrons and import them so authentication will be available. Early in the upgrade and late in the upgrade the SIP server will need to be taken down, once to point to the test system and again to upgrade it and point it back to production.
- Self check machines also use SIP and it will be important to not operate those during the down time. You don’t want transactions recorded on the test system.
- Offline circ will be available to record circulation transactions. It is important to review Michele’s offline checklist prior to the down time.
