  • Concurrent upgrade of primary and standby databases
    Patent number: 10817382
    Abstract: Methods and systems are provided for concurrently upgrading a primary database and a standby database that is synchronized with the primary database, while still protecting the stored data from the risk of hardware or other failure during the upgrade process. The standby database is mounted to an NFS (Network File System) located on a database access node. The upgraded primary and standby databases are built and mounted to the NFS mount point. A level-zero backup and one or more incremental backups of the deprecated standby database are generated. Each backup may be concurrently transferred to the upgraded databases via the mount point. Upon generation of a final incremental backup, the primary database is frozen and the tablespace metadata to transferred to the upgraded databases via the mount point. The upgraded primary database may be started upon importing of the tablespace metadata.
