Sample Configuration for Oracle Database on Amazon RDS

AWS provides Amazon Relational Database Service (Amazon RDS) that you can use to set up, operate, and scale a relational database on the cloud. Amazon RDS is license-based and works on a “pay only for what you use policy.” For more information about Amazon RDS, visit the Amazon Relational Database Service (RDS) website.

Perform the following steps to configure an Oracle database instance on Amazon RDS and establish connections with iProcess Engine:

1.

Create a database instance on Amazon RDS running Oracle. For more information, see the User’s Guide for Amazon Relational Database Service (Amazon RDS). After you select the database engine and specify details such as the identifier, password, and so on, the final step is to configure advanced settings for the database, which in this case is Oracle.

2.

On the Configure Advanced settings page, add the Oracle database instance to the VPC on which iProcess Engine exists or is to be installed. On this page, you can also define accessibility levels, availability zone, and security groups. The following table lists the fields and their respective values that you must configure on this page.

Database Settings

Field	Required Value
Virtual Private Cloud (VPC)	Select the VPC on which iProcess Engine exists or needs to be installed.
Subnet group	Defines the subnets and IP range that the DB instance can use in the selected VPC. You must create a subnet group for the database instance and then select the same in this field. For more information about creating subnets, see User’s Guide for Amazon RDS.
Public accessibility	Determines whether you want EC2 instances and devices outside the VPC to connect DB instance. If yes, a public IP is assigned to the DB instance.
Availability Zone	Specifies the availability zone of your DB instance.
VPC Security Group	In this field, you can choose an existing security group or create a new one. Security groups have rules authorizing connections from all EC2 instances and devices that must connect to the database instance.

For this sample configuration, the following table lists the security group settings for sg-iPE such that iProcess Engine can connect to the Oracle database instance on Amazon RDS.

VPC Port Range

Type	Protocol	Port Range	Source	Description
All traffic	All	All	192.0.2.0/32	From private network
All traffic	All	All	sg-iPE	From Oracle Database Server on Amazon RDS

The sample setup would resemble the following illustration.
