Maintenance and patches

Plexivo keeps your databases patched. Updates are applied in a weekly maintenance window you choose, after an email telling you what will change and when. The same window and controls apply to Plexivo Postgres, Plexivo MySQL and Plexivo Cache.

Choose your window#

On the resource’s Maintenance tab, under Maintenance window, set the Day, the time it Starts in your organisation’s time zone, and its Length: 1, 2, 3, 4, 6 or 8 hours. Choose Save window.

Until you choose, the window is Monday at 02:30 India Standard Time, for 3 hours.

Notice and postponing#

Each update is announced by email to every owner and admin, with every affected resource in one message, and a reminder 24 hours before. These announcements are always sent: they cannot be switched off in your notification settings. By default:

The Scheduled list shows what is coming. Postpone a week moves an update by a week, within those limits. Apply now applies it straight away. History lists what was done.

What happens during an update#

• Updates are applied to replicas first.
• A database with a standby switches over to an updated copy in seconds instead of stopping.
• A database without a standby restarts once, for about a minute.
• An update that is not healthy within 45 minutes, by default, is rolled back automatically.
• Continuous backups keep running throughout.

A Plexivo Cache restarts once during an update and is unavailable while it does.

Updates include security fixes and bug-fix releases of the engine, and new connection limits when Plexivo changes them, because a new limit needs a restart. Moving to a new major PostgreSQL version is never automatic: see Versions and upgrades.
