1. Create and implement OCI Queue by using its APIs and the Java SDK
  2. Prepare Your Environment

Prepare Your Environment

The environment(s) that act as the message source and message consumer needs to have Java and, optionally, Groovy installed. The example can work with Java 8 or later (Java 8 is sufficient to run the code using Groovy). This exercise in this playbook uses Java 11.

  1. Set the following policies in the compartment to be used:
    allow any-user to manage queues in compartment compartment-name
allow any-user to manage queue-pull in compartment compartment-name
allow any-user to manage queue-push in compartment compartment-name
  2. Provide the client and consumer user credentials to enable OCI connectivity.
  3. Download the following:

    Note:

    See the Explore More topic, elsewhere in this playbook, for live links to the resources listed below.
    • Provided source code from https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/javasdk.htm and the file system allowing files to be executed.
    • The OCI Java SDK and the code and scripts from https://github.com/oracle-devrel/oci-arch-queue-demo.

      You can find the steps for obtaining the SDK in this repository. You will need to unpack and the JARs into a /lib folder relative to the location of where you'll run the app (or amend the provided script to point to the desired folder).
