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">

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>
