In Oracle Integration Cloud (OIC), a package is a collection of integrations and their associated resources managed as a single unit. To maintain consistency and prevent runtime failures of in-flight instances, OIC enforces a strict prerequisite for modifying shared resources like connections. Before a connection within a package can be replaced, all integrations contained within that specific package must be in an inactive state. This ensures that no processes are actively using the connection during the update, thereby safeguarding data integrity and process stability.

B. You can only replace the connections used by the three active integrations.

This is incorrect. Replacing a connection for an active integration is prohibited as it would disrupt any currently running or scheduled instances.

C. You can only replace the connections used by the two inactive integrations.

This is incorrect. The rule applies to the entire package. Even if a connection is only used by inactive integrations, the package-level constraint requires all integrations to be inactive.

D. You cannot replace connections unless all integrations in thepackage are in an active state.

This is incorrect. This is the opposite of the required procedure. Performing such a change on active integrations would be unsafe and is not permitted.

1. Oracle Cloud Infrastructure Documentation - Using Integrations in Oracle Integration 3:

Section: Manage Packages > Update a Connection in a Package

Content: The documentation explicitly states as a prerequisite: "Before you begin, ensure that all integrations in the package are deactivated." This directly supports the correct answer.
