The guide addresses OutOfMemoryError issues in ServiceNow MID Servers, common in Java applications. It emphasizes diagnosis methods, particularly using yCrash, an advanced monitoring tool. The report highlights significant memory retention in HashMap instances, indicating memory leaks. Optimizing code and GC settings is crucial for improving application performance and stability.
Recent updates to the yCrash performance optimization suite, including GCeasy, fastThread, and HeapHero, introduce enhanced capabilities for JVM analysis, data security, automation, and advanced visual insights. New features include machine learning for error detection, REST APIs for integration, and Native Memory Tracking support, ensuring efficient application performance and streamlined troubleshooting for teams.
The recent webinar on Java Garbage Collection (GC) patterns highlighted their critical role in application performance and stability. It covered identifying patterns, diagnosing issues via GC logs, and managing memory leaks. Participants learned to optimize performance through informed adjustments, ensuring robust applications. Tailored expert advice was also provided during the Q&A session.
String deduplication saves memory by replacing repeated strings with references to just one copy. In Java, this can be done using the intern() method. In Java 8, specific settings are needed to activate this feature, while newer versions handle it automatically. Reviewing string deduplication logs helps assess how well memory is being used.
High Java I/O wait times in ServiceNow MID Servers can cause slowdowns, freezes, and high resource usage, making it difficult to troubleshoot and scale. This article shares tips for improving integration performance, provides a simulation program to show these issues in action, and highlights ways to identify performance bottlenecks effectively.
In a competitive business landscape, optimizing system performance and cost efficiency is crucial. Our webinar will explore real-world case studies from Fortune 500 companies that improved Garbage Collection (GC) performance. Attendees will gain insights, review GC logs, and learn nine practical tips to enhance Java application efficiency and scalability.
The yCrash monitoring tool for Java Spring Boot applications introduces minimal overhead, with CPU usage averaging 0.05% and memory consumption consistently between 0.1% and 0.2%. This non-intrusive approach ensures no significant impact on production environments, making yCrash an ideal choice for continuous application monitoring without compromising performance.
Every year in October, JAX London is the go-to event for Java and Software Architecture enthusiasts! It is a four-day conference for cutting-edge software engineers and enterprise-level professionals. This year, at JAX London’s 2024 conference, our architect Ram Lakshmanan was invited to talk on the topic: “TROUBLESHOOTING JVM OUTAGES - 3 FORTUNE 500 CASE STUDIES”.
