Controlling Server Clusters

Proxy Server enables you to control the remote servers in your cluster through the following actions:

• Starting and stopping the servers

• Viewing their access and error logs

• Transferring configuration files. If the master Administration Server has more then one instance of the Proxy Server, files can be transferred from any of these servers to any slave added to the cluster. Clusters must be homogeneous. All servers in a cluster must be of the same type, either UNIX or Windows. Transferring configuration files from a different platform may cause the server to hang or crash. The configuration files are:

  • server.xml

  • magnus.conf

  • obj.conf

  • mime.types

  • socks5.conf

  • bu.conf

  • icp.conf

  • parray.pat

  • parent.pat
