Exadata Database Server Patching using the DB Node Update Utility

Rene Kundersma
Software Engineer

Today the 'DB Node Update Utility' (dbnodeupdate.sh utility) has been made available. The 'DB Node Update Utility' automates all the steps and checks to upgrade Oracle Exadata database servers to a new Exadata release and replaces the manual steps. The dbnodeupdate.sh utility includes the latest best practices and workarounds for known issues. Where appropriate, the script uses existing 'One-Time Helper scripts' or 'yum update commands'. The script uses the 'build-in' 'dbserver_backup.sh' script to perform backups before patching where possible. 

Four typical use cases for the dbnodeupdate.sh utility are :

  • One-Time Setup  (updating procedure for Exadata releases running Oracle Linux 5.5 or later)
  • Updating database servers running Exadata releases later than on Oracle Linux 5.5 or later
  • Rolling back updates
  • Post-Patching (or Post-Rollback steps) (relinking the Oracle homes, enabling Grid Infrastructure to start)

For more details, demo's and downloads see My Oracle Support Note 1553103.1
