- Windchill 的 JVM 调整最佳实践
- Windchill PLM JVM 知识中心文章
- 有没有通用的 JVM 内存/GC 调整建议?
- 有没有通用的垃圾收集器(GC)调整建议?
- 管理员收到 JMX 通知邮件,内容如下:
Heap percentage usage threshold exceeded
Heap percentage usage threshold no longer exceeded
Heap percentage usage threshold still exceeded
Garbage collection time threshold exceeded; percentage time in garbage collection
Garbage collection time threshold still exceeded; percentage time in garbage collection
Garbage collection time threshold no longer exceeded; percentage time in garbage collection
Low Memory Detector wt.jmx.notif.memory java.management.memory.collection.threshold.exceeded poolName=PS Old Gen
java.lang.OutOfMemoryError heap space
wt.method.MemoryUsageRedirectStrategy - Usage threshold exceeded
- 方法服务器因java.lang.OutOfMemoryError: Java 堆空间而关闭:
wt.jmx.notif.gc - Name=GarbageCollectionNotifier, SourceObjectName=com.ptc:wt.subsystem=Monitors,wt.monitorType=GarbageCollection, class=class javax.management.Notification, type=wt.jmx.core.mbeans.GarbageCollectionMonitorMBean.percentTimeSpentInGCThreshold.exceeded
- 如果配置了 PTC System Monitor,可能会收到以下通知:
Application Process Unhealthy GC health of process is not ok. The process constantly spent more than 15% of it's execution time for Garbage Collection in the last 5 minutes
