This is the third in a series of blogs on data-driven microservices design mechanisms and transaction patterns with the Oracle converged database. The first blog illustrated how to connect to an Oracle database in Java, JavaScript, Python, .NET, and Go as succinctly as possible. The second blog illustrated how to use that connection to receive and send messages with Oracle AQ (Advanced Queueing) queues and topics and conduct an update and read from the database using all of these same languages. The goal of this third blog is to provide details on how to secure connections in these same languages as well as convenience integration features that are provided by microservice frameworks, specifically Helidon and Micronaut.
When making secure connections to Oracle databases there are two items to consider, the wallet and the password. We will discuss and provide examples of both in this blog.
