Both the Warehouse Proxy Agent and Warehouse Summarization and Pruning Agent can run in autonomous ("unmanaged") mode.
If a Warehouse Proxy Agent is running in connected ("managed") mode, it makes its location available to the monitoring servers and application monitoring agents by registering the location with the Global Location Broker on the hub monitoring server, along with a list of monitoring servers that it supports. Remote monitoring servers and the agents that connect to them obtain the network addresses of the proxy agents to which they report from the hub. However, if the Warehouse Proxy Agent is running in autonomous ("unmanaged") mode, it does not register its location with the hub monitoring server; instead, monitoring agents are configured to obtain the location of their Warehouse Proxy Agents from their local configuration file or from a central configuration server facility. This allows the Warehouse Proxy Agent to support monitoring agents that are running autonomously (that is, without a connection to a monitoring server).
If the Summarization and Pruning Agent is running in connected mode, it obtains the information it needs about the collected historical data from the Tivoli Enterprise Portal Server. If the Summarization and Pruning Agent is configured to run in autonomous mode, it obtains the information about attribute data directly from attribute support files for the monitoring agents, and the summarization and pruning settings from the WAREHOUSESUMPRUNE table in the warehouse database. The location of the application support files is specified in the Summarization and Pruning Agent configuration file (see Configuring a Summarization and Pruning Agent to run autonomously ). See Configuring summarization and pruning without the Tivoli Enterprise Portal Server for more information on the WAREHOUSESUMPRUNE table.
