11 SQL Server 2008 Manageability Enhancements Central Management Servers Policy-Based Management

12 Central Management Servers What Are Central Management Servers? How to Create a Central Management Server and Server Groups How to Execute Multiserver Queries

13 What Are Central Management Servers? Centralized management of multiple servers: Maintain connection information for servers in a server group: Only Windows authentication is supported Enable central administration of multiple servers: Multiserver queries Policy-based management Multiserver Query Configuration Server Server Group

14 How to Create a Central Management Server and Server Groups 1. Register a Central Management Server in the Registered Servers pane in SQL Server Management Studio 2 Create a new server group for the registered Central 2. Create a new server group for the registered Central Management Server

15 How to Execute Multiserver Queries Change Multiserver Results options as required Create query from Registered Servers pane By default, results are merged and include columns for server and login

16 Policy-Based Management What Is Policy-Based Management? What Are Facets, Conditions, and Targets? What Are Policies? Policy Execution Modes How to Create a Policy How to Apply Policies How to Evaluate Policies How to Assign Policies

17 What Is Policy-Based Management? Management by Intent Use the logical view that is provided through policies to define desired configuration of data services proactively Intelligent Monitoring Use policies to monitor, record, and optionally prevent changes from the desired d configuration Virtualized Management By using policy-based management, you can scale management across multiple servers, which makes it easy to enforce consistent configuration policies across the enterprise

18 What Are Facets, Conditions, and Targets? Facets An aspect of SQL Server management in which one or more related configuration options is defined Conditions Settings to define the state of a facet Target Entities such as servers, databases, logons, and other database objects to which policies can be applied

19 What Are Policies? A condition that is enforced on one or more targets Organized into categories

20 Policy Execution Modes On demand Automated policy execution: On schedule On change: prevent On change: log only

21 How to Create a Policy 1. Create necessary conditions based on the appropriate facets or determine which preconfigured conditions will meet your requirements 2. Create a policy and define the following: Policy name Check condition If enabled Execution mode Server restrictions Category Description Optional help hyperlink

22 How to Apply Policies Manually run policies that are configured with the On demand deployment mode to apply the policy Configure policies to be applied automatically: Set the deployment mode to On schedule, On change: log only, or On change: prevent Enable the policy Verify that the target belongs to the target set that is defined in the policy Verify subscription to the policy

23 How to Evaluate Policies Evaluate Policies i Manually Run Policies i Results appear in the Evaluate Policies window

24 How to Assign Policies Mandate Database Subscriptions Apply all policies in a category to all databases by using the Mandate Database Subscriptions setting Assign Policies to Individual Objects 1. Clear the Mandate Database Subscriptions setting 2. Use the Categories option on the Policies menu of the appropriate object, and then select the Subscribed check box for the appropriate category

25 SQL Server 2008 Performance Enhancements Managing Workloads by Using Resource Governor Monitoring Performance by Using Data Collector Managing Performance by Using Plan Freezing

26 Managing Workloads by Using Resource Governor What Is Resource Governor? What Are Resource Pools and Workload Groups? How to Manage Resource Governor How to Assign a Workload to a Workload Group

27 What Is Resource Governor? Resource Governor is a tool to define limits and assign priorities to individual workloads that are running on a SQL Server instance: Workloads are based on factors such as users, applications, and databases Limits control the resources that are available to specific workloads: Minimizes the effects of runaway queries Priorities can optimize the performance of a mission critical Priorities can optimize the performance of a mission-critical process while maintaining predictability for the other workloads on the server

28 What Are Resource Pools and Workload Groups? Resource pools: Can contain many workload groups Limit it system resources Workload groups: Are assigned to resource pools Group applications and limit resources that are specific to SQL Server

29 How to Manage Resource Governor 1. Enable Resource Governor 2. Configure resource pools 3. Configure workload groups 4. Create a classification function to assign workloads to workload groups

30 How to Assign a Workload to a Workload Group Create a classifier function CREATE FUNCTION dbo.fn_classifyapps() RETURNS sysname WITH SCHEMABINDING AS BEGIN sysname IF (APP_NAME() LIKE '%Low Importance Application%') Importance Group' END GO ALTER RESOURCE GOVERNOR WITH (CLASSIFIER_FUNCTION FUNCTION = dbo.fn_classifyapps) ALTER RESOURCE GOVERNOR RECONFIGURE

31 Monitoring Performance by Using Data Collector What Is Data Collector? Data Collection Architecture How to Configure a Management Data Warehouse How to Manage Data Collection How to View Performance Data

32 What Is Data Collector? It is a set of tools to collect performance information It provides an API that enables client applications to access performance data It includes SQL Server Agent jobs and SSIS packages that provide data to the API It provides a management data warehouse that stores historical performance data

33 Data Collection Architecture SQL Server Agent schedules the Data Collector run-time component The Data Collector runtime component executes the Data Collector SSIS packages The SSIS packages collect the data from the data providers and upload it to the management data warehouse Client Reports API Storage SQL Server Management Studio Class library Execution Data Collector API Stored procedures And views SSIS Data collection configuration Console interface Data Collector Run-time component SQL Server Agent SSIS packages Audit and history Jobs definition iti

34 How to Configure a Management Data Warehouse Use the Configure Management Data Warehouse Wizard to: Specify a database to store collected data and specify a folder location for temporary storage before upload Specify user and group access to the management data warehouse

35 How to Manage Data Collection Configure the three System Data collection sets: Disk Usage Query Statistics Server Activity You can specify: Upload schedule Collection frequency Security Retention ti period You can view: Input parameters to define Input parameters to define the Transact-SQL used to gather the data

36 How to View Performance Data To view reports, right-click Data Collection, point to Reports, and then click one of the available options: Some reports have links to more specific information

37 Managing Performance by Using Plan Freezing What Is Plan Freezing? Scenarios for Plan Freezing How to Create a Plan Guide How to Enable and Disable a Plan Guide How to Copy a Plan Guide

38 What Is Plan Freezing? Plan freezing creates a plan guide that: Contains hints or a full query plan Is attached to a specific Transact-SQL statement t t Can be enabled or disabled Can be copied between servers exec = = start

39 Scenarios for Plan Freezing SQL Server upgrade: Query plans are often updated during migration Most updates are beneficial i Plan guides enable you to roll back detrimental query plan updates Prevent query regression: You can create plan guides and then disable them to enable queries to benefit from statistics-based recompiles If the query regresses, you can enable the plan guide to revert to the previous query plan Copy plan guides: You can script plan guides on test servers and then apply them to production servers Enable thorough testing of plan guides before deployment

40 How to Create a Plan Guide 1. Execute DBCC FREEPROCCACHE to clear the query cache 2. Execute queries for which you want to create a plan guide 3. Execute sp_create_plan_guide_from_handle to create plan guides for the specific query or for every query in the cache

41 How to Enable and Disable a Plan Guide To enable a plan guide: New plan guides are enabled by default EXEC sp_control_plan_guide N'ENABLE', N'CustomerSales' To disable a plan guide: EXEC sp_control_plan_guide N'DISABLE', N'CustomerSales' '

42 How to Copy a Plan Guide 1. Script plan guide in SQL Server Management Studio on source server: Plan guides are also included in complete database scripts 2. Execute script on destination server
