Additionally, you can direct Database Cloud Service to set up automatic backups. Finally, the deployment includes cloud tooling that simplifies backup, recovery, patching and upgrade operations. You have root privilege, so you can load and run software in the compute environment.You have full administrative privileges for the Oracle database.
