Edition Date Software Version --------------------------------------------------------------------------------------- First Edition January 1995 C.50.00 Preface This manual, Using the HP 3000 Workload Manager, is an introduction to using the Workload Manager on the 900 Series HP 3000 computer systems. It provides background information on traditional CPU scheduling (prior to Release 5.0), explains workgroups, and describes the procedures and processes for partitioning the system workload into workgroups. This manual is written primarily in task format. To perform a task, simply look it up in the table of contents or in the index, turn to that section, read the introduction and follow the steps and examples. The information in Chapter Five ("Commands Reference") and the Appendices is arranged alphabetically and should be used as reference material. In This Book This manual is your guide to using the Workload Manager on the 900 Series HP 3000. Chapter 1 Introducing the Workload Manager provides an overview of the Workload Manager and introduces workgroups. Chapter 2 Planning for Workgroups provides guidelines for translating the specific needs of system users into an effective workgroup configuration. It also includes an overview of key process scheduling concepts. Chapter 3 Creating Workgroups teaches the system manager how to create, modify and purge user-defined workgroups. It also describes how to replace the entire workgroup configuration now and at a scheduled time in the future. Chapter 4 Tuning System Performance explains how to change the scheduling characteristics of user-defined workgroups to optimize system performance and how to use the Workload Manager to respond to performance problems as they arise. Chapter 5 Commands Reference documents each of the eight commands you will use with workgroups. Appendix A Troubleshooting provides a list of common problems you may encounter using the Workload Manager and suggests various solutions. Appendix B Error Messages lists the messages that you can encounter when using workgroups, describes a probable cause, and suggests one or more actions to remedy the error. In addition, a Glossary and an Index help you find, use and understand the information in this manual. This manual contains information subject to change without notice. Conventions UPPERCASE In a syntax statement, commands and keywords are shown in uppercase characters. The characters must be entered in the order shown; however, you can enter the characters in either uppercase or lowercase. For example: COMMAND can be entered as any of the following: command Command COMMAND It cannot, however, be entered as: comm com_mand comamnd italics In a syntax statement or an example, a word in italics represents a parameter or argument that you must replace with the actual value. In the following example, you must replace filename with the name of the file: COMMAND filename bold italics In a syntax statement, a word in bold italics represents a parameter that you must replace with the actual value. In the following example, you must replace filename with the name of the file: COMMAND(filename) punctuation In a syntax statement, punctuation characters (other than brackets, braces, vertical bars, and ellipses) must be entered exactly as shown. In the following example, the parentheses and colon must be entered: (filename):(filename) underlining Within an example that contains interactive dialog, user input and user responses to prompts are indicated by underlining. In the following example, yes is the user's response to the prompt: Do you want to continue? >> yes { } In a syntax statement, braces enclose required elements. When several elements are stacked within braces, you must select one. In the following example, you must select either ON or OFF: COMMAND { ON } { OFF} [ ] In a syntax statement, brackets enclose optional elements. In the following example, OPTION can be omitted: COMMAND filename [OPTION] When several elements are stacked within brackets, you can select one or none of the elements. In the following example, you can select OPTION or parameter or neither. The elements cannot be repeated. COMMAND filename [ OPTION ] [ parameter] Conventions (continued) [...] In a syntax statement, horizontal ellipses enclosed in brackets indicate that you can repeatedly select the element(s) that appear within the immediately preceding pair of brackets or braces. In the example below, you can select parameter zero or more times. Each instance of parameter must be preceded by a comma: [,parameter][...] In the example below, you only use the comma as a delimiter if parameter is repeated; no comma is used before the first occurrence of parameter: [parameter][,...] |...| In a syntax statement, horizontal ellipses enclosed in vertical bars indicate that you can select more than one element within the immediately preceding pair of brackets or braces. However, each particular element can only be selected once. In the following example, you must select A, AB, BA, or B. The elements cannot be repeated. { A} |...| { B} ... In an example, horizontal or vertical ellipses indicate where portions of an example have been omitted. In a syntax statement, the space symbol shows a required blank. In the following example, parameter and parameter must be separated with a blank: (parameter) (parameter) The symbol indicates a key on the keyboard. For example, RETURN represents the carriage return key or Shift represents the shift key. CTRLcharacter CTRLcharacter indicates a control character. For example, CTRLY means that you press the control key and the Y key simultaneously.
