Using the HP 3000 Workload Manager

Gathering Data for the Workload Manager 

In the following sections, you'll learn some techniques for using HP
GlancePlus with the Workload Manager.  You can use the performance tool
of your choice to evaluate current system performance and, once you have
set up workgroups on your system, evaluate their behavior.

Using GlancePlus to gather information 

To use Workload Manager with GlancePlus, you edit the configuration file
Glancnfg to add workgroups to an existing application class specification
or to define a new application class that corresponds to a workgroup.
When you associate the new WORKGROUP keyword with a Workload Manager
workgroup, the resources used by this process will be added to the
resources used by other processes in the application class.

You can set up GlancePlus applications in three ways, each of which is
explained below.

   *   One application class to one workgroup.

   *   One application class to many workgroups.

   *   One workgroup to many application classes.

Assigning one application class to one workgroup.     

To define an application class that maps exactly to a single workgroup,
you enter the application name and the name of the workgroup in the
configuration file.  For example, the following specification defines an
application called Data Entry and maps it to the Data_Entry workgroup:

     APPLICATION=Data Entry
     WORKGROUP=Data_Entry

This application class contains all processes that are members of the
Data_Entry workgroup, and no other processes.

Assigning one application class to many workgroups.     

You may want to define an application class that partitions the processes
in a workgroup into discrete groups.  For example, suppose you have
defined the following Sales workgroup:

     :newwg Sales;memb_logon=("dept@.@.sales");base=160;limit=180 

You can then define two different applications to view the processes in
this one workgroup by adding this application class specification to the
glancnfg file:

     APPLICATION=Dept1
     USER="dept1@.@.sales"

     APPLICATION=Dept2
     USER="dept2@,@.sales"

Assigning one workgroup to many application classes.     

There may be a situation in which you want one application class to
provide data on multiple workgroups.  For example, suppose that you have
defined two workgroups on your system, Billing and Payroll, but for the
purpose of performance evaluation, you can lump them into one application
called Finance.  To do so, you would add this application class
specification to your glancnfg file:

     APPLICATION=Finance
     WORKGROUP=Billing, Payroll

Viewing workgroup data in GlancePlus.     

Once you have set up workgroups in the Glancnfg file, you can use the new
Workload Manager screen to display information about workgroups.  To
access the Workload Manager screen, issue the K command from any window
or, at the GlancePlus global window, press the Workload Manager softkey  
F1.


NOTE  To analyze a portion of the system workload, use the Filter screen
      to select the information that you want to see.  Press the F key to
      define a filter, enter the appropriate information, (program, user,
      or application), and press  Return.
