SSAS:如何查看服务器会话并且有选择性地终止某些会话

在SSAS的管理维护工作中，我们经常需要查看服务器当前的会话信息，并且根据实际情况有选择性进行终止某些会话。例如某些会话的时间过长，或者异常情况。

1. 如何查看会话列表

<Discover xmlns="urn:schemas-microsoft-com:xml-analysis">
    <RequestType>DISCOVER_SESSIONS</RequestType>
    <Restrictions>
        <RestrictionList>
        </RestrictionList>
    </Restrictions>
    <Properties>
        <PropertyList>
           </PropertyList>
    </Properties>
</Discover>

这个语句看到的结果大致如下

<return xmlns="urn:schemas-microsoft-com:xml-analysis">
  <root xmlns="urn:schemas-microsoft-com:xml-analysis:rowset" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

</return>

2. 如何终止某个会话,使用Cancel命令即可

<Cancel xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">
  <SessionID>A8D16CE6-8472-4186-BBBD-7A3CB60C4DD3</SessionID>
</Cancel>
