Video Tutorial: How to Schedule an Upgrade


 



Resolution


The process for investigating an upgrade includes the following: 

  1. The change request modifies the glide.war.assigned property in the instance. When the scheduled start time is reached, the property gets modified to the requested WAR version.
  2. There is a scheduled job called Upgrade that checks in each hour to verify if the glide.war.assigned property has changed. The job will run if the glide.war.assigned and glide.war properties are different.
  3. The Upgrade job downloads the WAR file and the instance restarts. At this point, the nodes/stats show that the instance is upgraded, but the database upgrade has not run yet.
  4. Once the instance restarts, the Check Upgrade Script scheduled job runs. This job gets assigned to a single node that runs the database upgrade.
