SystemView ® Host Management Facilities/VM Overview
SystemView* Host Management Facilities/VM is an integrated set of VM
services that have received wide use and acceptance within the IBM
Corporation. They were designed to make systems management for VM
easier. These services may help you reduce the cost of managing VM
systems by allowing system programmers and other system support people to
do more work in less time.
Host Management Facilities can actively monitor the status of your
application service virtual machines (SVMs), and restart SVMs it finds
down. You can use Host Management Facilities to schedule and automate
your system events (activities) at the specific times or within the time
frames you want.
Host Management Facilities comes with a command routing and broadcasting
service that simplifies communications between users, applications, and
systems. After it is tailored to your installation, the service can look
up how a command must be sent to a particular application (or across
systems), translate the command accordingly, and send it. Systems can be
nicknamed so that one command can be broadcast to many remote sites. You
no longer have to think about communications protocols or command syntax.
Just enter the command in your own predefined shorthand.
Host Management Facilities has an automated console service that works
like VM's Programmable Operator facility. The automated console can
filter messages or trigger automatic actions when it receives a specific
message. It also offers enhancements over VM's Programmable Operator
facility. For example, you can specify user lists in the routing table
(RTABLE), so that the same RTABLE entry can be used to handle a similar
message from a number of different user IDs.
Host Management Facilities comes with a cross-system single console image
facility (SCIF) service, called the Aid facility, that allows multiple
consoles to be controlled from the console of one virtual machine. When
the Aid facility is used with RSCS networking, authorized users can
monitor (and send commands to) consoles on other systems as well.
Host Management Facilities provides the means to automate the collection
and consolidation of performance data on your VM systems. The data can
be viewed at a dedicated terminal or workstation. Used with a real-time
monitor product, Host Management Facilities also aids in performance
monitoring, analysis, and problem solving. It can actively gather
short-term trend information about how your VM systems are performing,
and display the trends in graphical form at your terminal. You can set
up Host Management Facilities to take corrective measures automatically
whenever it detects exception conditions on monitored systems. Both
single and distributed system environments are supported.
Host Management Facilities conforms to SystemView Integration Level 1.
SystemView is the IBM systems management strategy for planning,
coordinating, and operating heterogeneous, enterprise-wide information
systems. SystemView is part of IBM*'s Systems Application Architecture*,
and is based on open standards such as Open Systems Interconnection
(OSI), current IBM architectures such as SAA and Systems Network
Architecture (SNA), and new architectures for systems management.
The SystemView strategy consists of SystemView-conforming products and
the SystemView structure. The SystemView structure is designed to make
systems management software more uniform, and thus easier to use. It
advocates consistent user interfaces, shared data, enhanced automation,
and increased integration among systems management products.
