Clients
A client is a processor that can access the nodes in a cluster over a local area network. Clients each run a front-end or client application that queries the server application running on the cluster node.
HACMP™ provides a highly-available environment for critical data and applications on cluster nodes. Note that HACMP does not make the clients themselves highly available. AIX® clients can use the Client Information (Clinfo) services to receive notification of cluster events. Clinfo provides an API that displays cluster status information. The /usr/es/sbin/cluster/clstat utility, a Clinfo client provided with HACMP, provides information about all cluster service interfaces.
