21 Define Classification Dialog Box

Use the Define Classification dialog box to define workload classes and subclasses.

A class is a set of criteria that can be applied to one or more processes; for example, Batch is one of the default classes for OpenVMS while root is a default class for UNIX. A subclass is a set of events within a process that follows a certain transaction definition. Currently, the software is limited to image names as subclass events.

21.1.1 Importing the PSDC$PARAMS.DAT File

You can import classifications from PerfCap Performance Data Collector for OpenVMS to use with PerfCap Capacity Planner. The Capacity Planner software reads all the workloads in the PSDC$PARAMS.DAT database and determines whether each is a class or subclass definition.

To import the PSDC$PARAMS.DAT file:

  1. Choose Import PSDC$PARAMS.DAT from the File menu.

    The Workload Translation to Classes/Subclasses dialog box is displayed.

  2. Follow the steps for using the Workload Translation to Classes/Subclasses dialog box.

21.1.2 Importing Class Definitions

You can import class and subclass definitions from a memory file to use with PerfCap Capacity Planner.

To import class and subclass definitions:

  1. Choose Import class definitions from the File menu.

    The File Selection dialog box is displayed with a default filter of your current directory and *.MEMORY (OpenVMS) or *.memory (UNIX).

  2. Follow the steps for using the File Selection dialog box.

21.1.6 Defining or Changing Classes and Subclasses

You can define new classes and subclasses for a set of processes using the Define Classification dialog box. You can also change attributes of a class or subclass.

To define a new class for a set of processes:

  1. Enter the name of the class in the Current Class text field of the Define Classification dialog box and press the Return key.

    The class name is added to the list box and the Define Classes dialog box is displayed.

  2. Complete the fields in the Define Classes dialog box and click on OK.

    The changes are applied and the dialog box is removed.

To change the attributes for an existing class:

  1. Click on the name of the class in the Class List box, then click on the Define... button or Define... item in the Edit menu.

    The Define Classes dialog box is displayed.

  2. Complete the fields in the Define Classes dialog box and click on OK.

    The changes are applied and the dialog box is removed.

To define a new subclass:

  1. Enter a subclass name in the Current Subclass text field in the Define Classification dialog box and press the Return key.

    The Define Subclasses dialog box is displayed.

  2. Complete the fields in the Define Subclasses dialog box and click on OK.

    The changes are applied and the dialog box is removed.

To change the attributes for an existing subclass:

  1. Click on the name of the subclass in the Subclass List box, then click on the Define... button or Define... item in the Edit menu.

  2. Complete the fields in the Define Subclasses dialog box and click on OK.

    The changes are applied and the dialog box is removed.

21.1.7 Using Default Classes or Subclasses

Default classes are provided with the software. They are:

Default subclasses are provided with the software. They are the same for both OpenVMS and UNIX:

To use default classes or subclasses:

  1. From the Control menu, choose Use Defaults to select classes or subclasses appropriate for the system on which the Capacity Planner is running

    or

    choose OpenVMS Defaults or Digital UNIX Defaults.

    The default classes or subclasses are displayed in the Class or Subclass List box.

  2. Select one of the classes or subclasses by clicking on it if you want to examine or modify it.

    Its name is displayed in the Current Class or Current Subclass field.

21.1.8 Adding PATHWORKS Classes

You can add two default PATHWORKS classes to the Class List: PWServer and PWClient. The PWServer class appears at the top of the class list, while the PWClient class appears at the end of the class list. This is the recommended order.

The PWServer class includes the PATHWORKS process that runs on the server. The PWClient class includes client PCs that interface with the server through PATHWORKS.

To add the default PATHWORKS classes to the class list, choose Add Pathworks from the Control menu.

21.1.9 Specifying the List of Classes or Subclasses

When you open the Define Classification dialog box, the Class List box is displayed. To change to the Subclass List box, choose Subclass List from the Control menu. To change back to the Class list box, choose Class List from the Control menu.

21.1.10 Reordering the Class or Subclass List

The list of classes or subclasses in the Define Classification dialog box are arranged in a particular order:

The order is important because the Capacity Planner software uses a waterfall effect. That is, the software allocates processes to classes or subclasses on a first-match basis. For example, if the process MY_JOB were included in classes SMALL and BATCH, MY_JOB would be included in the SMALL class if SMALL appeared first in the class list. The process would not be split between the two classes.

To change the order of the class or subclass list:

  1. Choose Reorder List from the Control menu.

    The Reorder Classes or Reorder Subclasses dialog box is opened.

  2. Follow the steps for using the Reorder Classes or Reorder Subclasses dialog box.
