Updated on 15th November 2018 with the latest changes for deploying Oracle EBS (R12) on Cloud (OCI).

This post covers the 15 Things every Oracle Apps DBAs or Technical Architects must know when deploying/migrating Oracle EBS (R12) on Oracle Cloud (OCI).

If you want to look at the tasks performed by Oracle Apps DBAs in Cloud or the new role for Oracle Cloud Apps DBA, then look at my previous post here.

15 Things Oracle Apps DBAs must know for Oracle Cloud

1. Cloud has three Service Models mainly.

• Infrastructure as a Service (IaaS)
• Platform as a Service (PaaS)
• Software as a Service (SaaS)

To know more about Cloud Service Models, Check my previous video post Here.

Note: As an Oracle Cloud Apps DBA, you’ll be working on IaaS & PaaS Service Model.

2. Under IaaS, Oracle has two main offerings (OCI & OCI-C). For EBS (R12), you can also have dedicated compute on Sparc Model.

• Oracle Cloud Infrastructure (OCI) Compute — This was Bare Metal Cloud Service (BMCS) earlier.
• Oracle Cloud Infrastructure Classic (OCI-C) Compute (Compute Classic) — This was the original Compute earlier.
• Oracle Cloud Infrastructure Compute Classic — Dedicated Compute Capacity — SPARC Model 300

Note: To know more about OCI (click Here) & differences between OCI & OCI-C refer Here.

3. Oracle Database Cloud Service’s (DBCS) offering is from PaaS and has two main common options (apart from Schema as a Service)

• Database as a Service (DBaaS)
• Exadata Cloud Service (ExaCS)

Note: Autonomous Database on OCI is not certified with EBS R12 on Cloud yet. 

4. Oracle EBS (R12) has two main tiers (Third is Client Tier i.e.Java-enabled Browser).

• Database Tier: Oracle EBS Database is deployed in this tier.
• Application Tier: Oracle EBS Middle Tier (like Fusion Middleware, OHS, WebLogic, etc).

5. You can deploy EBS on a Cloud in three ways:

• Traditional Deployment: In a traditional deployment, we deploy everything on the customer hardware.
• Hybrid Deployment: In a hybrid deployment, we deploy Apps tier on Customer hardware and database tier on Cloud.
• Oracle Public Cloud: In this deployment, apps tier will be deployed on IaaS and Database tier can be deployed on IaaS or PaaS (DBCS or Exadata CS).

6. EBS (R12) Application Tier must be deployed on IaaS and is supported on all the three IaaS offerings from Oracle (OCI Compute, OCI Compute Classic, OCI Compute Classic SPARC).

7. EBS R12 (Database) can be deployed on either IaaS or PaaS (DBCS offering). EBS R12 Database Tier on PaaS can be configured with either DBaaS or ExaCS

8. Oracle Database Cloud Service (DBCS) has four options for Software Editions ( More on this at my previous post Here).

• Standard Edition (SE)
• Enterprise Edition (EE)
• Enterprise Edition High Performance (EE-HP)
• Enterprise Edition Extreme Performance (EE-EP)

9. If Oracle EBS (R12) Database Tier is using Oracle Database Cloud Service, then Software Edition should be either EE-HP or EE-EP. 

10. If EBS (R12) Application Tier is on IaaS and Database Tier is on PaaS (DBCS or ExaCS), then these two services must be co-located in the same Identity Domain. (More on Identity Domain, Here and Here )

11. You can run Oracle EBS(R12) with RAC on Oracle Cloud but in that case, Database Tier must be on PaaS Offering (DBCS or ExaCS)

12. You can create new Oracle EBS (R12) – Vision or Fresh Database using:

• Template from Oracle Cloud Marketplace
• Using EBS Cloud Manager tool. 
  Note: EBS Cloud Manager is used to deploy EBS on OCI  wherein EBS Cloud Admin Tool is used to deploy EBS on OCI-C 

Note: EBS Cloud Manager Tool is a recommended approach for provisioning Oracle EBS (R12) Instance in Oracle Cloud Infrastructure (OCI). 

13. You can Lift & Shift (Migrate) an On-Premise EBS (R12) Instance to Oracle Cloud using Automated Method. For things to consider before EBS (R12)  migration to Oracle Cloud, Check our blog post 10 Things to Consider before Migration to Cloud.

14. Oracle Cloud at Customer (OCC) is a service where Customer can keep Oracle Cloud Machines (On Subscription Basis) at their own data centers and run EBS on Cloud similar to Oracle Public Cloud.

15. Oracle EBS R12 is NOT certified on Amazon AWS (IaaS).
