Oracle E-Business Suite Components
Oracle E-Business Suite has a three-tier architecture consisting of client, application, and database (DB) tiers.
The client tier contains the client user interface, which is provided through HTML or Java applets in a web browser for forms-based applications.
The application tier consists of Oracle Fusion Middleware (Oracle HTTP Server and Oracle WebLogic Server) and the concurrent processing server. The Fusion Middleware server has HTTP, Java, and Forms services that process the
business logic and talk to the database tier.
The Oracle HTTP Server (OHS) accepts incoming HTTP requests from clients and routes the
requests to the Oracle Web Logic Server (WLS), which hosts the business logic and other server- side components. The HTTP services, forms
services, and concurrent processing server can be installed on multiple application tier nodes and load balanced.
The database tier consists of an Oracle database that stores the data for Oracle E-Business Suite.
This tier has the Oracle database executables and the Oracle database files that physically store the tables, indexes, and other database objects in the system.

Migration Accelerators
➢Snowball
➢AWS DirectConnect
➢AWS Storage Gateway
Migration Accelerators - Snowball
• Snowball is a petabyte-scale data transport solution that uses secure devices to transfer large amounts of data into and out of AWS services. Using Snowball addresses common challenges with large-scale data transfers including high network costs, long transfer
times, and security concerns. Transferring data with Snowball is simple, fast, secure, and can be as little as one-fifth the cost of high-speed Internet
• Available in 2 flavors – Snowball and Snowball Edge
Migration Accelerators - DirectConnect
AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your
premises to AWS. Using AWS Direct Connect, you can establish private connectivity
between AWS and your datacenter, office, or colocation environment, which in many
cases can reduce your network costs,
increase bandwidth throughput, and provide a more consistent network experience than Internetbased connections
Migration Accelerators - StorageGateway
AWS Storage Gateway is a hybrid storage service that enables your on-premises applications to seamlessly use AWS cloud storage. You can use the service for backup and archiving, disaster recovery, cloud data processing, storage tiering, and migration. The service helps you reduce and simplify your datacenter and branch or remote office storage infrastructure.
Your applications connect to the service through a virtual
machine or hardware gateway appliance using standard storage protocols, such as NFS, SMB and iSCSI. The gateway connects to AWS storage services, such as Amazon S3, Amazon Glacier, Amazon EBS, and AWS Backup, providing storage for files, volumes, snapshots, and virtual tapes in AWS. The service includes a highly-optimized data transfer mechanism, with bandwidth management, automated network resilience, and efficient data transfer, along with a local cache for low-latency on- premises access to your most active data.
Gather EBS License Consumption (On-Prem)
Execute the below on your On Prem EBS environment
• ORAchk - Oracle ORAchk extends health check coverage to the entire Oracle software stack and identifies and addresses top issues reported by Oracle users. Oracle ORAchk proactively scans for known problems with Oracle products and deployments
• OSWatcher - Oracle OS watcher (OSWatcher) reports CPU, RAM and Network stress, and is a new alternative for monitoring Oracle servers
• AWR (If you have Diagnostic Pack Licenses): Automatic workload
Repository collects, processes, and maintains performance statistics for the database
Analyze the Reports & Baseline EBS License Usage
Review and Analyze the AWR Reports, OSWatcher Output and ORAchk Reports and prepare the baseline for License usage
You Look for:
What software Components & features being used – like Partitioning, Compression etc.
How Many CPUs/Cores being used
How many Users are existing on the system
What is the transaction volume – (No of Order Lines etc)
Oracle Software Licensing Models
• Server-based licenses (based on Cores used) – Processor licenses
– Named User Plus licenses
• Unlimited License Agreements (ULA)
• Varying others (PULA, ISV, etc..)
• http://www.orafaq.com/wiki/Oracle_licensing
• https://docs.aws.amazon.com/aws-technical-content/latest/oracle-database-aws-bestpractices/oracle-licensing- considerations.html
Oracle Licensing – Standard Processor based
Processor - Shall be defined as all processors where the Oracle programs are installed and/or running.
Programs licensed on a processor basis may be accessed by your internal users (including agents and contractors) and by your third-party users. All cores on all multicore chips for each licensed program are to be aggregated before multiplying by the appropriate core processor licensing factor and all fractions of a number are to be rounded up to the next whole number. The number of required licenses shall be
determined by multiplying the total number of cores of the processor by the core-factor. For e.g. Core Factor for Intel is 0.5 and Core Factor for Sun is 0.25 Oracle Processor Core Factor Table which can be accessed at http://oracle.com/contracts
• All processors where the program is installed and/or running must be licensed.
• With the Processor metric, there is no limit to the number of users, regardless of whether they access the program directly or via a front-end application
Oracle Software Licensing - NUPs
• Named User Plus: is defined as an individual authorized by you to use the programs which are installed on a single server or multiple servers, regardless of whether the individual is actively using the
programs at any given time. A nonhuman operated device will be counted as a named user plus in addition to all individuals authorized to use the programs, if such devices can access the programs. If multiplexing hardware or software (e.g., a TP monitor or a web server product) is used, this number must be measured at the multiplexing front end. Automated batching of data from computer to computer is permitted. You are responsible for ensuring that the named user plus per processor
minimums are maintained for the programs contained in the user minimum table in the licensing rules section; the minimums table provides for the minimum number of named users plus required and all actual users must be licensed
• The Named User Plus metric allows you to license your programs by the number of users/non-human operated devices (has to be countable). The standard Named User Plus license minimum for Oracle Database Enterprise Edition is 25 Named User Plus licenses for every licensable processor
Oracle Licensing Considerations on AWS
http://www.oracle.com/us/corporate/pricing/cloud-licensing-070579.pdf AWS EC2 and RDS:
- Count two vCPUs as equivalent to one Oracle Processor license if hyper-threading is enabled, and one vCPU as equivalent to one Oracle Processor license if hyper-threading is not enabled.
When counting Oracle Processor license requirements in Authorized Cloud Environments, the Oracle Processor Core Factor Table is not applicable
In all AWS instance types, each vCPU is a hyperthread of an Intel Xeon core except for T2 and m3.medium
Running Servers on AWS EC2
Running EBS services on EC2, you have the below options - Shared Host (Virtualized)
- Dedicated Host (Physical Server)
AWS EC2
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier.
Benefits are - Elastic web-scale computing, Flexible cloud hosting services, Inexpensive, Easy to provision, Reliable and Secure!
Customer Responsibility - Licensing of Oracle Database Enterprise Edition and Options - Managing the Compute Instance and Database
Oracle Database Editions and Licensing
• Enterprise Edition. Most expensive, complete database.
• Standard Edition 2: May only be licensed on servers that have a maximum capacity of 2 sockets.
• Personal Edition (single user database) • Enterprise Edition is required with the following configurations:
• When the server has got more than 2 sockets OR You are using Tuning or Diagnostic Pack OR You are using Database Options (e.g. Partitioning)
• You have to pay for the Database Options, besides the ‘default’ Enterprise Edition database licenses, e.g.:
• Real Application Clusters
• Partitioning
• Advanced Security
• Database Vault
• Advanced Compression
• Active Data Guard
• Real Application Testing
• Label Security
• Total Recall
• Spatial
• In-Memory Database Cache
• Data Mining
