1 SQL Server Administration suite Class 3 of 4 Activant Prophet 21 SQL Server Management

2 This class is designed for Beginner SQL/Prophet 21 Users who are responsible for SQL Administration as it relates to Prophet 21 Completed the following classes in this suite Introduction to SQL Server 2000: Installation and Implementation SQL Server Data Storage

3 Perform backups Perform restores Objectives Maintenance Plans Create and maintain SQL and Prophet 21 logins

4 This course will NOT cover Windows Navigation Installation of SQL Server SQL Server Data Storage Data Manipulation

5 Implementing an Maintenance Plan Benefits Protection Data Integrity Guards against system failures

6 Implementing an Maintenance Plan Typical Tasks Regular and frequent backups of database and transaction log Data Consistency checking Index Rebuilding

7 Implementing an Maintenance Plan Accomplished through SQL Enterprise Manager Transact-SQL statements

8 Regular and Frequent Backups Databases are typically large Backup entire database when all users are off the system Time consuming Maintain data integrity Utilize the transaction log Backup changes since last backup Saves time

9 Differential Backups Database backup Backs up changes since last full database backup Must already have a full database backup

10 Backup Strategy Sun Mon Tues Wed Thurs Fri Sat Full databas e backup Transaction Log Log backs up up every hour. FAILURE --PM PM Downtime = 9 hours Production database = 50GB Max performance 4 AM to 2 AM weekdays Full database backup takes 5 hours

11 Backup Strategy with Differential Sun Mon Tues Wed Thurs Fri Sat Full database backup Transaction Log Log backs up up every hour. FAILURE --PM PM Downtime = 6 ½ hours Production database = 50GB Differential backups every night. Max performance 4 AM to 2 AM weekdays Full database backup takes 5 hours

12 Performing Backups Expand Database Right-click Choose All Tasks Backup Database

13 General

14 Backup Destination

15 Backup Device

16 New Device

17 Performing Backups - General

18 Performing Backups - Options

19 Backup Commands Backing up a Database BACKUP DATABASE {database name} TO {backup device name} WITH {(DIFFERENTIAL) (options)} Backing up a Transaction Log BACKUP LOG {database name} TO {backup device name} WITH {options}

20 Restore

21 Restore

22 Restore Commands Restoring a Full or Differential Database Backup RESTORE DATABASE {database name} TO {backup device name} WITH {options} Restoring a Transaction Log Backup RESTORE LOG {database name} TO {backup device name} WITH {options}

23 Backup Verification RESTORE VERIFY ONLY FROM <backup device> Verifies that all files in the backup set are complete and readable Bad track Bad tape Bad sector on a disk Does NOT verify the structure of the data

24 Database Maintenance Wizard Setup ALL administrative actions Creates scheduled jobs for you

25 Data Consistency Checking (DBCC) Corrupt data in database = Corrupt data in backup Must be run from Query Analyzer Off Hours is best to run 3 Commands DBCC CHECKDB DBCC CHECKALLOC DBCC CHECKCATALOG

26 Data Consistency Checking (DBCC) DBCC CHECKDB [(database name [,NOINDEX])] DBCC CHECKALLOC [(database name [,NOINDEX])] DBCC CHECKCATALOG [(database name)]

27 Index Rebuilding Index pages fill up to their 8k limit New extent is allocated to insert a pointer Page Splitting can occur (Index fragment)

28 Index Rebuilding DBCC DBREINDEX (<table_name>, <index_name>, FillFactor) Rebuilds indexes one at a time

29 Index Statistics Updated every time a query is run Index fragmentations are recorded in statistics Query Optimizer determines the most efficient way to run a query based upon statistics UPDATE STATISTICS <table_name>

30 Operators Setup to tell SQL Server who is taking care of server How and when to notify them

46 SQL Agent Mail SQL Server has access to a MAPI compliant mail server SQL Server Agent Service must be running under a domain user account Domain user account must have a mail profile set up on SQL Server Mail client must be configured on SQL Server

47 Managing Database Logins and Permissions User management Database server logins Database users Database permissions Managing logins for Prophet 21

48 Two levels User Management Database Server Logins Allows users to login to the database server Passwords are kept at server level Database Users Must be user on specified database No additional passwords are required

49 User Management Managed in two ways Creates server login for user Maps this login to a database user Permissions are applied at the server level and database level Statement permissions User performs database level operations Proper permissions Access and/or modify tables

50 Database Server Logins

51 Add New Login

52 New Login - General

53 New Login Server Roles

54 New Login Database Access

55 Fixed Server Roles Role Sysadmin Dbcreator Diskadmin Permission Perform any activity Create and alter databases Manage Disk Files Processadmin Manage SQL Server processes Serveradmin Setupadmin Configure server-wide settings Install replication Securityadmin Manage and audit server logins

56 Fixed Database Roles Role Public Db_owner Db_accessadmin Db_ddladmin Db_securityadmin Permission Maintain all default permissions Perform any database role activity Add or remove database users, groups, and roles Add, modify, or drop database objects Assign statement and object permissions

58 Database Permissions Assigned using SQL Enterprise Manager Transact-SQL GRANT statement

59 Database Permissions Using SQL Statement Statement Permissions GRANT {ALL statement_list} TO {PUBLIC name_list} Object Permissions GRANT {ALL permission_list} ON {table_name [(column_list)] view_name [(column_list)] stored_procedure_name extended_stored_procedure_name} TO {PUBLIC name_list}

60 Database Permissions Using SQL Enterprise In the Server Manager window, rightclick the database on which you want to grant permissions Select Properties Click the Permissions tab Choose options

61 Grant Object Level Permissions Drill down to the object on which you want to grant permissions Right-click the object, point to All Tasks, and then select Manage Permissions Grant permissions to the objects or database roles you want

62 Managing Logins for Prophet 21 (CommerceCenter) Users are created in System Setup

63 Additional Administration and Debugging Tools SQL Server Profiler SQL Query Analyzer
