Oracle E-Business Suite Releases 12.2 and 12.1.3 are now certified with Oracle Database 19c on key database cloud services. Whether on-premises or in Oracle Cloud, 19c databases used by Oracle E-Business Suite always use a multitenant architecture with a single pluggable database (single tenant). Note that the application tier always resides on an OCI Compute virtual machine.
Be aware that from the point of view of database certification, environments that run solely on Compute without taking advantage of Oracle's database services are equivalent to on-premises environments running on Oracle Linux.
Oracle E-Business Suite on OCI automation, including the EBS Cloud Manager and the EBS Cloud Backup Module, now supports the following capabilities with Database 19c:
For a full description of automation features, see the related blog article Get Release 20.1.1 of EBS Cloud Automation for Oracle Cloud Infrastructure.
How you upgrade will depend on the Cloud service you use to run your database: Compute, or a database cloud service (including VM DB Systems or Exadata DB Systems). Each of these two cases is summarized below.
To manually upgrade your Oracle E-Business Suite database on the OCI Compute service, you can use the on-premises procedure by following the My Oracle Support (MOS) document applicable to your release:
Be aware that if you currently use Cloud Manager to manage your environment, you can continue to do so after the database upgrade by running a provided script to update the Cloud Manager metadata.
For more information, see Section 6.4.5, Upgrading to Oracle Database 19c, in Getting Started with Oracle E-Business Suite on Oracle Cloud Infrastructure (MOS Note 2517025.1).
Forthcoming procedures will facilitate an upgrade to Oracle Database 19c for Oracle E-Business Suite environments currently using Oracle Database Releases 18.104.22.168 or 22.214.171.124 on OCI VM DB Systems and Exadata DB Systems.
