Adding to Existing Cloud Account
If you currently own an Oracle Cloud account and want to link the newly purchased Oracle Financial Services Cloud service to that account, follow the instructions in this page.
Open the Welcome email you received from Oracle Cloud with the subject Action Required: Welcome to New Oracle Cloud Service Subscription(s) and click on the Add to existing cloud account link on it. This opens up the Oracle Cloud Account login page where you can log in to your existing cloud account. This automatically activates the newly purchased cloud service under the same cloud account.
