WebScale™
Cluster Control
After you have installed and configured WebScale, you can control its operations and
modify parameter settings using the WebScale control program, webscale.exe, which is
installed in your %SYSTEM_ROOT%\system32 directory. To simplify and centralize
system administration, you can run webscale.exe either on the cluster hosts or on any
remote Windows NT 4.0 system that can reach the cluster over a local or wide area
network. Certain actions, such as modifying parameters, can only be performed on the
cluster hosts. Because it is a console-based application, this program can be
incorporated into scripts used for system management.
The command line for webscale.exe has the following form:
webscale <command> [<cluster>[:<host>] [<remote options>]]
Addressing Cluster Hosts
You can omit the cluster, host, and remote options when running webscale.exe directly
on a cluster host. In this case, the command applies only to the local cluster host. You
also can specify the target cluster and/or cluster host for the command. The cluster
parameter refers to the cluster's Internet name or primary cluster IP address. If the host
parameter is omitted, the command applies to all hosts within the cluster and is
multicast to the hosts. Otherwise, the command applies to the specified host within the
cluster. The following table summarizes the forms that the cluster and host parameters
may take:
Cluster:Host Action
(omitted) Invokes command on
local cluster host.
cluster Invokes command on
all cluster hosts.
cluster:host Invokes command on
specific cluster host.
You can specify cluster and host names as Internet host names or as their equivalent IP
addresses. In addition, you can specify host names using their unique host priorities that
were entered in the WebScale Setup dialog. You can use the special host priority value
0 to refer to the default host within a cluster.
Examples:
mycluster:host1
Example
webscale stop
webscale stop mycluster
webscale stop \
mycluster:host1
