How to trigger your instance upgradeIssue When you schedule an instance upgrade, you want to monitor the process and ensure that it starts on time. This Knowledge Base article describes the scheduled jobs that control upgrades and the available monitoring tools that can help you take control of them. Scheduled Jobs There are two critical scheduled jobs that execute the upgrade process: Check distribution for possible upgrade: Runs every 60 minutes to check if the instance is associated with a new .war file. (A new .war file is associated with an instance when you submit an upgrade request.) Check database for possible upgrade: Looks for a new .war file when a node is restarted. If a new file is found, it begins updating the database. Keep in mind that the Upgrade scheduled job runs every 60 minutes, but not necessarily at the top of the hour. For example, the scheduled job could run 15 minutes past the hour or 20 minutes before the hour. Example Once you submit an upgrade request via the Now Support (HI), a change request number is created, if your upgrade hasn't started within the scheduled window on the change request, this is likely because the Check distribution for possible upgrade job, which is responsible for triggering your upgrade to start, has not yet run on your instance. You can determine when the Check distribution for possible upgrade job will run on your instance by following the steps below: Navigate to System Scheduler > Scheduled Jobs > Scheduled Jobs.In the list, find the Check distribution for possible upgrade scheduled job.View the Next action column to determine when the job next runs. For example, if the next action is 11:10:00, the scheduled job will run at 11:10:00 and then at 10 minutes past the hour every hour (because the scheduled job is set to run every 60 minutes).
