适用于

  • ThingWorx Platform 9.0 to 10.0
  • Microsoft SQL Server
  • Azure SQL Server

说明

  • 主动-主动高可用性 (HA) ThingWorx 实例偶尔会返回错误ChangeWatcher failed to sync在ThingworxStorage\logs\ApplicationLog.log 文件中，并且该实例无法正常工作。
      • 无法登录 ThingWorx
      • 集群中的 ThingWorx 平台节点意外关闭
      • LDAP用户无法登录ThingWorx
      • 节点上的模型更改不会反映到其他节点，例如权限更改。

    • 当Microsoft SQL Server配置为高可用性实例时，ThingWorx 平台是否会自动连接到数据库？ 数据库？
    • ThingworxStorage\logs\ ApplicationLog.log 中存在错误：
