If the patch fails, you should run the rollback script to remove the patch and restore your old instance. You can then fix the errors that caused the failure and reapply the patch.
The rollback script restores your old instance from the backup file created by the patch script. Before running the script, you should know the absolute path to this file, which is defined by the BDD_BACKUP_FILE
property in the bdd-cloud-cron-env.properties
file.
