Oracle DbaaS Test Connect Failure in ICS

Summary

ICS Test DbaaS Connection failing after updating the schema password

Content

A number of integrations in ICS using a Oracle DbaaS Connection. The connection was created few months back, today the database schema password was changed and we had to update the ICS connection with new password. Now the Test Connection is failing with error "The connection test failed. Check your connection and use agent from agent group.". However, existing integrations using the connection are working fine.

We had not created any agent for our connection and it was working fine. Can anyone highlight any possible reason for this issue?
