Optimize Java Applications and Simplify Uptaking New JDK Versions with Java Management Service

Oracle is pleased to announce that with the latest update of Java Management Service (JMS), system administrators can quickly maximize the performance of their Java applications through expert recommendations tailored to each applications' profile. JMS now also offers invaluable insight to developers looking to take advantage of the many performance and language improvements of newer JDK versions for their existing applications.

Performance Analysis: Optimize Your Java Application Performance

JMS administrators can now leverage Performance Analysis feature to obtain recommendations to improve the performance of their Java applications. This feature analyzes the performance statistics from your Java runtime powering your applications and interprets them to recommend optimal startup parameters to enhance their performance.

By analyzing garbage collection logs and JFR files, Performance Analysis identifies specific areas for optimization and suggests updated startup parameters. With this feature, administrators can identify performance bottlenecks and take appropriate measures to optimize the overall performance of their Java applications.

Java Management Service recommendations for improving application performance

Java Migration Analysis: Streamline Your Adoption of New JDK Versions

JMS facilitates the migration of applications from older JDKs to newer ones for developers seeking to take advantage of the latest performance enhancements and language improvements. Through its Migration Analysis feature, JMS performs a comprehensive analysis of the application and generates detailed reports calling out the potential effort and risk involved in the migration process.

The Migration Analysis report provides developers with a clear picture of the level of effort required to transition to a newer JDK version. Migration Analysis also allows developers to easily consider different JDK version choices. By quantifying the effort involved in migrating to different JDK versions, developers can make informed decisions about which JDK version to migrate to.

During the migration process, developers can utilize the analysis reports from Migration Analysis to identify classes and APIs that require changes. The reports specify line numbers in the source code where modifications are needed and highlight both mandatory and recommended changes.

The report is available in two formats:

1. In JMS Fleet Management: The report can be viewed in the OCI console from the fleet where the Migration analysis action was initiated.

2. Static HTML: The report can be downloaded from the OCI console, enabling easy sharing with other team members for collaborative analysis and discussion.
