Welcome to the FAQ article about Commvault's Java Runtime Environment (JRE) usage and support. In this article, we'll address common questions and concerns related to the usage of JREs in Commvault's server components and CommCell Console.
Question: What is the role of Java Runtime Environment (JRE) in Commvault? Answer: In all currently supported versions of Commvault, server components utilize the Commvault JRE. This JRE is a repackaging of the AdoptOpenJDK or Temurin JREs. It's important to note that these JREs are completely free and do not incur any license fees.
Question: How frequently is the Commvault JRE updated? Answer: The Commvault JRE is routinely updated to newer Java versions along with other Commvault updates. This ensures that your Commvault environment benefits from the latest Java enhancements and security improvements.
Question: Is the CommCell Console dependent on the Commvault JRE? Answer: If you install the CommCell Console using the Commvault installer, it can be run locally using the Commvault JRE. In this scenario, no additional Java software is required. This simplifies the setup and ensures compatibility.
Question: Can the CommCell Console be accessed via a web browser? Answer: Yes. The CommCell Console can be accessed with a web browser from any machine. In this scenario, however, a JRE must be present on the machine where you intend to run the Console. Unlike when using the Commvault installer, the JRE in this case will not be installed or managed by Commvault.
Question: How can I find more information about using the CommCell Console? Answer: You can find more detailed information about using the CommCell Console, including information about JRE requirements and setup, in the official Commvault documentation. Visit this link to access the relevant documentation.
Question: Can I use my own JRE with Commvault components? Answer: While the Commvault JRE is recommended for optimal compatibility, you can use your own JRE with Commvault components. However, it's important to ensure that your chosen JRE version is compatible with the specific Commvault version you are using.
Question: Are there any considerations for security and compatibility when using external JREs? Answer: When using an external JRE, ensure that it is up to date with security patches and compatible with Commvault's requirements. Using an outdated or incompatible JRE might lead to performance issues or security vulnerabilities.
Question: What are AdoptOpenJDK and Temurin JREs? Answer: AdoptOpenJDK and Temurin are popular distributions of the OpenJDK project, which is an open-source implementation of the Java Platform, Standard Edition. Commvault repackages these JREs for use in their server components.
Question: How do I stay informed about updates and changes to Commvault's JRE usage? Answer: To stay informed about updates, changes, and best practices regarding Commvault's JRE usage, regularly check the official Commvault documentation and any announcements from Commvault regarding updates and releases. For further assistance or more specific queries, refer to the official documentation or reach out to Commvault's support team.
