Windchill PDMLink 和 FlexPLM 中服务器管理器、方法服务器和后台方法服务器的堆内存大小

• 如何更改服务器管理器、方法服务器和后台方法服务器的堆内存大小
• 管理员收到 Java 管理扩展 (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
  • wt.jmx.notif.memory message=Memory usage exceeds collection usage threshold
• MethodServer 因错误java.lang.OutOfMemoryError: Java heap space不足而关闭
• MethodServer 已停止运行 错误： java.lang.OutOfMemoryError: GC overhead limit exceeded
• MethodServer 崩溃了内存不足
• Windchill 正在自动关闭，一段时间后将重新启动。
• 如果已配置 PTC 系统监控器，则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

• wt.manager.maxHeap的单位是什么？
• Java虚拟机(JVM)启动失败，错误信息：Java运行时环境内存不足，无法继续运行。
• 重新托管后，方法服务器 (MS) 启动失败，并卡在以下行：
