Prepare for Upgrade

Before upgrading to JMS, ensure you have a foundational understanding of certain key concepts, especially those related to Oracle Cloud Infrastructure (OCI) and JMS:

  • Oracle Cloud basics: Familiarize yourself with the fundamental concepts and practices associated with Oracle Cloud. Understanding the core principles of cloud computing and OCI will provide the necessary context for your adoption of JMS within Oracle Cloud.
  • JMS Key Concepts and Terminology: Gain insight into the core concepts and terminology specific to Java Management Service (JMS). Familiarity with JMS terminology and functionality will ease your adoption and enable you to effectively harness its capabilities.
In addition to these concepts, there are practical tasks to complete before transitioning from AMC to JMS:
  • Stop AMC Agents: As both AMC and JMS depend on the Java Usage Tracker, you must stop the operation of AMC agents on all desktops. This step is necessary to prevent any conflicts and ensure the proper reporting of Java usage by JMS agents.
  • Save AMC Reports: AMC reports are incompatible with JMS. They cannot be migrated due to differences in data formats and the additional fields captured by JMS. As JMS will only have data from the date its agents were installed, it is recommended to save AMC usage reports separately for reference and historical analysis.

While JMS itself does not require any dedicated hardware and the associated maintenance costs, it does rely on Oracle Cloud Infrastructure Monitoring, Logging, and Object Storage Services. For detailed information on the associated costs, refer to the service descriptions provided in Oracle Cloud Services Contracts.

These key details will play a pivotal role in evaluating the suitability of JMS for your organization and equip you with the tools necessary to confidently embark on your journey with JMS and harness its capabilities to their fullest potential.

Getting Started

Now that you have a good understanding of JMS features, the following steps will help you get started:

  1. Create an OCI account if you don't already have one. You can get started for free by registering at https://cloud.oracle.com/free.
  2. Gain hands-on experience with JMS using Livelabs or follow the instructions in the JMS user guide to manage Java runtimes, applications, and managed instances inventory with Java Management Service.

If you are a Java SE Subscription customer, you can reach out to Oracle Support to start using JMS. The support team is equipped to assess your requirements and AMC deployments, and provide a tailored onboarding plan for you.
