In Oracle Integration Cloud (OIC), Lookups are used to store and manage key-value pairs or reference data that can be used within integrations and mappings. Lookups provide a convenient way to store and retrieve static data or configuration information that is needed in your integration flows. Here are the key aspects of using Lookups in Oracle Integration Cloud:

1. Creating a Lookup:

• • To create a Lookup in Oracle Integration Cloud, you can access the Oracle Integration Cloud Console and navigate to the Integration section.
  • Under the “Integration” section, select “Lookups” and then click the “Create” button to create a new Lookup.

1. Defining Lookup Entries:

• • Each Lookup consists of one or more entries, where each entry contains a key-value pair.
  • You can define Lookup entries manually by specifying a key and its associated value.
  • Additionally, you can import Lookup data from an external source, such as a CSV file, to populate the entries.

1. Using Lookups in Integrations:

• • Lookups can be used within your integration flows to retrieve values based on keys.
  • In mapping expressions or conditional statements, you can reference a Lookup to retrieve the corresponding value.
  • This is particularly useful for scenarios where you need to map values between systems or apply business logic based on reference data.

1. Dynamic Lookups:

• • In some cases, you may need to perform dynamic Lookups where the key is determined at runtime based on data within the integration.
  • Oracle Integration Cloud allows you to use expressions to construct dynamic keys and perform Lookups accordingly.

1. Versioning and Revisions:

• • Lookups support versioning, which means you can create different versions of a Lookup as your reference data evolves.
  • This helps in maintaining historical Lookup data while making updates for future use.

1. Security and Access Control:

• • You can control who has access to view and modify Lookups by configuring security policies and access control within Oracle Integration Cloud.

1. Testing Lookups:

• • During development and testing, you can use the “Test Lookup” feature in Oracle Integration Cloud to verify that Lookups return the expected values.

1. Lookups in Orchestrations:

• • Lookups can also be used within Orchestrations in Oracle Integration Cloud to retrieve reference data and make decisions based on that data.

1. Monitoring and Logging:

• • You can monitor Lookup activity and log Lookup-related events to track how Lookups are being used within your integration flows.
