  discussion about TCP vs. UDP

  • UDP uni-cast
  • UDP adds four bytes of header information
  • In most of the cases we ended up using mostly TCP for data replication and UDP for discovery.

使用jps查看java进程ID

在Linux上经常需要查看Java的进程ID，例如想kill掉某个Java进程就需要pid。使用ps + grep可能觉得不是很方便，如果classpath很长，输出会非常难看。
其实从JDK1.5开始，Sun就提供了一个非常方便的Java进程查看工具：jps 。 配合适当的参数，输出一目了然。例如，我经常使用jps -lv，
-l
Output the full package name for the application's main class or the full path name to the application's JAR file.
-v
Output the arguments passed to the JVM.

更多的参数可以查看jdk的文档http://java.sun.com/javase/6/docs/technotes/tools/share/jps.html

JDK提供这个工具是为了和其他的Troubleshooting工具配合使用，例如jmap、jstack，这些工具也很有意思，有兴趣的可以尝试用用http://java.sun.com/javase/6/docs/technotes/tools/index.html#troubleshoot。
