适用场景

  • ActiveIQ Unified Manager (AIQUM)
  • SnapMirror

问题解答

  • 端口要求文档中所述的必需端口之外找到的端口 是一个即用端口
  • 临时端口(也称为动态端口)是客户端应用程序用来与MySQL等服务器应用程序建立传出连接的临时网络端口
  • 当Java应用程序连接到MySQL服务器时、它会从操作系统指定的范围中动态选择任何可用的终端端口
  • 一个端口的范围通常介于 1024到65536
  • 临时端口是临时端口、连接关闭后会释放这些端口
  • 不能在AIQUM应用程序中减少这些数量、因为它们对于与MySQL服务器进行安全通信至关重要
  • 选择的范围取决于操作系统
  • 这些端口可通过AIQUM或SnapMirror 与集群之间的数据包跟踪查看
