Practices *****************************ILLEGAL FOR NON-TRAINER USE***************************** Explain the purpose of the module Describe the list of learning objectives Module 4: Managing Applications and Services by Using Process Control Process Execution Environment Topic Objective To describe the process execution environment Lead-in The purpose of this section is to make sure that you understand priority, affinity, and scheduling Processes, Threads, and Fibers Scheduling Thread Priorities Scheduler Processor and Thread Affinity *****************************ILLEGAL FOR NON-TRAINER USE***************************** The purpose of this section is to make sure that you understand priority, affinity, and scheduling Later in the module, you will apply these concepts when using the Process Control tool Introduce the topic, Process Execution Environment The following four supportive slides discuss Processes, Threads, and Fibers; Scheduling Thread Priorities; Scheduler; and Processor and Thread Affinity This section provides the students with an opportunity to learn about the concepts of priority, affinity, and scheduling These concepts will be applied later in the module when they use the Process Control tool This section begins with a discussion of processes, threads, and fibers Next, you will have an opportunity to determine how base priority is assigned This leads into an explanation of how scheduler uses the assigned base priority to allocate processor time This section concludes with a discussion about processor and thread affinity Module 4: Managing Applications and Services by Using Process Control Processes, Threads, and Fibers Topic Objective To identify processes, threads, and fibers Process Process Lead-in Thread Thread To understand the concepts and control that the Process Control tool uses, the student must understand how code is executed in a computer running Windows 2000-based operating systems Example.exe Thread Thread Thread Fibers +1 Thread +1 Thread Code Data Process Tree Process Tree Fibers Fibers *****************************ILLEGAL FOR NON-TRAINER USE***************************** To understand the concepts and control that the Process Control tool uses, you must understand how code is executed in a computer running Windows 2000based operating systems Describe processes, threads, and fibers Briefly introduce scheduling, which will be covered in the next two slides In the graphic, the entire box represents a process The left column, including Example.exe, with code and data, represents a thread The middle circle represents a process tree The right column represents fibers in a thread There are several key elements: Processes Threads Fibers Scheduling A process provides the resources needed to execute an application or program, including a collection of allocated virtual memory space, executable code, data, threads, and system resources A thread is executable code that is to be serially executed within a process A processor or CPU executes threads, not processes, so each 32-bit application must have at least one process and one thread A process always has at least one thread of execution, known as the primary thread, and can have multiple threads in addition to this After a thread is scheduled to execute, the thread continues to run until it is complete, is ended by some event, or is interrupted by a thread with higher priority (by a user action or the kernel's thread scheduler) Each thread can run separate sections of code, or multiple threads can execute the same section of code Threads that execute the same block of code maintain separate stacks All threads of a process share its virtual address space and system resources In addition, each thread maintains exception handlers, a scheduling priority, and a set of structures that the operating system uses to save the thread context until it is scheduled The thread context includes the thread's set of machine registers, the kernel stack, a thread environment block, and a user stack in the address space of the thread's process 60 Module 4: Managing Applications and Services by Using Process Control Lab A:

key points Lead-in The review questions cover some of the key concepts taught in the module Process Execution Environment Job Objects Process Control Concepts Rules, Processes, and Process Groups Configuring the Process Control Service Rules Defining Process Alias Rules *****************************ILLEGAL FOR NON-TRAINER USE***************************** How is base priority determined? It is the sum of the priority level and the priority class Describe a job object A job object: • Is a kernel object that is namable, securable, sharable, and inheritable • Groups one or more processes together • Controls attributes of the processes associated with them • Can enforce limits on each associated process • Collects and retains accounting information Processes running within a job object can create child processes Name two ways that you can access the Process Control service through the user interface MMC console and snap-in Command-line utility 72 Module 4: Managing Applications and Services by Using Process Control What is the difference between a process and a process group? A process is an instance of a program running in a computer A process group is a container for a designated group of processes that have been collected by a user for simplified management What does the process scan interval set? The process scan interval sets the number of seconds between scans of all Process Control managed processes Name the three types of rules that Process Control uses Process Alias rule Process Execution rules Process Group Execution rules What is a Process Alias rule? Process Control identifies processes in a meaningful way by assigning each process an intuitive alias based on a list of Process Alias rules that you define Module 4: Managing Applications and Services by Using Process Control 73 Review (continued) Topic Objective To reinforce module objectives by reviewing key points Lead-in The review questions cover some of the key concepts taught in the module Defining Process Execution Rules Setting Process Group Execution Rule Properties Managing Processes and Process Groups Managing Processes by Using the Command Line Backing Up and Restoring Process Control Information Best Practices *****************************ILLEGAL FOR NON-TRAINER USE***************************** What is a Process Execution rule? A Process Execution rule can associate a rule with a process alias and specify the affinity, priority, and working set of an individual process What is a Process Group Execution rule? A Process Group Execution rule manages and controls the execution of processes grouped together in a process group Process Group Execution rules provide hard limits by using job objects to control grouped processes The grouped processes cannot exceed the limits set by the rule 74 Module 4: Managing Applications and Services by Using Process Control 10 Explain the three ways that you can manage rules by using the Process Control console You can: • Modify Process Alias rules by using the Process Alias Rules object in the Rules object • Modify Process Execution rules by using the Process Execution Rules object in the Rules object In addition, you can manage Process Execution rules by using the Processes object in the Process Control console Click Processes, right-click the process you want to manage, and then click Properties • Manage Process Group Execution rules by using the Process Group Execution Rules object in the Rules object In addition, you can manage Process Execution rules by using the Process Groups object in the Process Control console If you expand the Process Groups object, you see the groups that you can manage If you click the individual group, a list of the grouped Process Execution rules appears in the details pane 11 How can you manage processes by using the command line? The Process Control command-line utility uses a series of switches that describe the operation to perform and supply the required data 12 Where does Process Control store all of its configuration information? It stores its configuration information in the Windows 2000 registry 13 Based on best practices, if your desired actual range of operation is 55–65 percent (a span of 10 percent), what should your controlled range be? As a rule, the range of operation maintained by Process Control should be at least 50 percent higher and 50 percent lower than the actual range desired For example, if the actual range desired is 55–65 percent (a span of 10 percent), your controlled range should be at least 50–70 percent (a span of 20 percent) ... vi Module 4: Managing Applications and Services by Using Process Control Lab A: Managing Applications and Services by Using Process Control In this lab, students have an opportunity to manage applications. .. a process alias Process Control uses the Process Execution rule to control how and where the process runs 30 Module 4: Managing Applications and Services by Using Process Control Naming a Process. .. the Process Control UI can be scripted, managed with graphical tools, or controlled from the command line Module 4: Managing Applications and Services by Using Process Control 15 Process Control
