Prepare to migrate your Oracle Integration Cloud Service instances to Oracle Integration.
Size Oracle Integration Instances
Size your Oracle Integration instances to determine the number of message packs required for your environment.
The concept of sizing is different between Oracle Integration Cloud Service and Oracle Integration.
- Oracle Integration Cloud Service sizing is based on connections.
- Oracle Integration sizing is based on message packs.
There is no 1:1 correspondence between the number of connections and the number of message packs. Therefore, you must estimate the relationship. Follow these sizing best practices to determine the number of message packs needed:
- Identify the number of Oracle Integration Cloud
Service messages by monitoring the Dashboard page. For example:
- How many messages were processed over a specific time period (for example, three days).
- What are the message types being processed (for example, file-based messages or SOAP/REST-based messages).
For specific questions, contact your customer support representative for advice on sizing.
- Configure the development environment with different message pack numbers than test and production environments. For example, it is recommended that you configure development to use a minimal number of message packs because you are not running load or performance tests in that environment.
- Size the test environment similar to the development environment, unless you know that you have regular usages large enough to require more message packs. A test environment may only run a fraction of the production environment volume most of the time. Typically, a performance test environment would run regular production volumes or more for a short period of time (such as two weeks).
- Always estimate the number of messages before deciding on the number of message packs to use.
- Guesstimates are fine. The message packs can be increased or decreased, if necessary, from within the Oracle Cloud Infrastructure Console.
Determine message packs needed for Processes for your environment, then add that number to those needed for standalone Integrations and other Oracle Integration features.
The concept of sizing is different between Oracle Process Cloud Service and Oracle Integration.
- Oracle Process Cloud Service sizing is based on named users.
- Oracle Integration Process sizing is based on concurrent users, which are converted to message packs.
Each concurrent user (which is a distinct user during that hour) per hour is counted as 400 messages per user. This number is added to the integration volume towards the 5,000 messages per hour. If you have 1,000 messages per hour and 10 distinct users, these would count as 1,000 integration messages + (400)*10 users = 5,000, so 1 message pack of 5,000 messages per hour would suffice.
Another way to visualize Process sizing: 5,000 message packs per hour equate to 12.5 distinct concurrent users performing tasks.
A logged in user is counted for a minimum of one hour when performing any write operations that update a task or process instance, which includes:
- Updating or processing tasks (approve/reject a task, add an attachment/comment, re-assign, or request for information)
- Creating process instances
Within each hour of use, a distinct user can perform an unlimited number of write operations.
Oracle Integration has a 1 message pack minimum charge per hour to keep the system available, even with no usage. Note that you can turn off your Oracle Integration instance for billing purposes, but no instances are processed while the instance is stopped.
What's NOT counted?
This count doesn’t include:
- Logged in users performing read-only only (query or read) operations.
- Integrations triggered from the process (integrations are waived).
Between 9am and 10am, 20 employees access Workspace. Within the one hour timeframe:
5 users (user1 through user5) create a total of 100 new process instances.
10 other users (user6 through user15) process different tasks created by user1 through user5, and complete them.
The remaining 5 users (user16 through user20) only check the task and process instance status, but do not perform any update/write operations.
Result: The 9am-10 am hour block reports 15 concurrent users (5 created new instances and 10 processed tasks).
Between 10 and 11am, 10 users access Workspace and 5 access the Oracle Process Mobile app. Within the one hour timeframe:
10 users (user1 through user10) create new process instances and also approve at least 1 task total.
5 users (user11 through user15) log into the mobile app: 3 of them create new instances, and the other 2 perform only read-only operations.
Result: The 10am-11am hour block reports 13 concurrent users (10 workspace users plus 3 mobile users performed update/write operations, while 2 mobile users did not perform any update/write operations).
Between 11am and 12pm, 5 users access Oracle Integration from a Visual Builder application and 5 other users access Workspace.
2 of the 5 Visual Builder users access Visual Builder, and interact with a Visual Builder app that in turn triggers execution of an API that creates new process instances and processes tasks.
The other 3 Visual Builder users access the Visual Builder app and read and access task and process instance status.
The 5 users access Workspace and approve a minimum of 1 task each within the hour timeframe.
Result: The 11am-12pm hour block reports 7 concurrent users (2 Visual Builder users and 5 Workspace users performed update/write operations). This result does not include the Visual Builder concurrent user licenses. Visual Builder concurrent users need to be sized separately.
Allowlist IP Addresses
You may have allowlisted your Oracle Integration Cloud Service IP addresses (explicitly allow identified entities access). For example, to access an FTP server. Or perhaps Oracle ERP Cloud calls back to Oracle Integration Cloud Service and you allowlisted some of the Oracle Integration Cloud Service IP addresses with Oracle ERP Cloud.
Perform the following steps:
- Provision your new instances. This is because allowlisting IP addresses can take approximately three weeks.
- File a service request to allowlist IP addresses. Include information from the
About button of your Oracle Integration instance. To access the About button:
- Go to the Oracle Integration Home page.
- In the upper right corner, click the username icon.
- From the list, select About.
Enable Oracle Integration Generation 2 Entitlement
If your cloud account was created in a home region of North America or Asia before Nov 13, 2019, or in a home region of EMEA or Latin America before Dec 12, 2019, discuss with your Oracle representative whether your account needs Oracle Integration Generation 2 entitlement.
Enable Access to the Application Migration Service
If you plan to use the Application Migration Service (the recommended tool), ensure that you can access it in your Oracle Cloud Infrastructure tenancy.
See the Prerequisites section in Overview of Application Migration.
Understand Best Practices for Migrating the Connectivity Agent
If using the connectivity agent, follow these best practices for migrating the agent to Oracle Integration.
- If using the Application Migration Service:
- Create and complete a migration of Oracle Integration Cloud Service. See Step 4: Migrate Oracle Integration Cloud Service and Oracle Process Cloud Service Design-Time Metadata into Oracle Integration.
- If using the
- Export the Oracle Integration Cloud Service archive. See Export the Oracle Integration Cloud Service Design-Time Metadata.
- Import the archive into Oracle Integration, but do not select the mode to activate integrations automatically.
ImportOnly. This allows you time to verify that your integrations have been properly imported into Oracle Integration before activation. See Import Design-Time Metadata into Oracle Integration.
- Download and install the Oracle Integration agent. You cannot use the Oracle Integration Cloud Service agent installation.
- Verify that the agent is registered in Oracle Integration and running.
- Use the REST API to activate integrations or manually activate each integration
on the Integrations page.
Note:If you run Oracle Integration and Oracle Integration Cloud Service side by side, the agents for both environments can co-exist.
