Much More Than Just Great DBAs • Focusing on world-class remote database support for all major database products • Over 60 customers and thousands of database servers under our control • Oracle Ace, Microsoft Certified DBA’s on staff • Almost 70 years combined SQL DBA experience. Much More than Just Great DBA’s

Top SQL 2008 New Features • Management Studio Improvements • Compression • Resource Governor • New Data Types • Performance Data Collector • Transparent Data Encryption • SQL Server Audit • Extended Events • Change Data Capture • Power Shell Much More than Just Great DBA’s

Management Studio Improvements • Activity Monitor • Object Explorer Details • Object Search • Multi Server Queries • Intellisense • T-SQL Debugger Much More than Just Great DBA’s

Activity Monitor At a glance performance information Automatically run a trace • Graphs • Processes • Data File I/O • Recent Expensive Queries Much More than Just Great DBA’s

Activity Monitor - Graphs • Percent Processor Time • Waiting Tasks • Database I/O • Batch Requests per Second Much More than Just Great DBA’s

Activity Monitor - Processes • Provides metrics for key resources • Identifies potential trouble spots • Measures the time a worker thread has to wait gain access to server resources Much More than Just Great DBA’s

Activity Monitor – Resource Waits • Provides metrics for key resources • Identifies potential trouble spots • Measures the time a worker thread has to wait gain access to server resources Much More than Just Great DBA’s

Activity Monitor – Data File I/O • Quickly determine databases that have high disk usage. • Columns can be sorted and filtered Much More than Just Great DBA’s

Activity Monitor – Recent Expensive Queries • Displays the queries in cache that have consumed the most resources. • Right click to display execution plan • Right click to display the entire query Much More than Just Great DBA’s

Activity Monitor – Object Explorer Detail • 36 possible columns of information about a database • Views are automatically remembered • CTRL-C copies the information to the clipboard in a tab delimited format, past into Excel to create reports Much More than Just Great DBA’s

Activity Monitor – Object Search • Searches for all objects within the selected scope: server, database, tables. • Wild card characters can be used. Much More than Just Great DBA’s

Activity Monitor – Multi-Server Queries • Queries all registered servers within the server group. • Returns results for each server. Much More than Just Great DBA’s

Activity Monitor – Intellisense • Highlights syntax errors. – Keywords – Object names Much More than Just Great DBA’s

Activity Monitor – Intellisense • Completes variables, commands, or object names • Incremental as you type Much More than Just Great DBA’s

Activity Monitor – Intellisense • Displays parameters for procedures and functions. • Can display a list of available objects for selection. Much More than Just Great DBA’s

Activity Monitor – T-SQL Debugger Much More than Just Great DBA’s

Activity Monitor – T-SQL Debugger • Steps into and over T-SQL code. • Developers will be more comfortable with features that they have become accustomed to in .Net • Displays the values of local variables and the call stack. • Start by hitting the F11 key. Much More than Just Great DBA’s

Compression • Data Compression – This includes row and page level compression and occurs within the .mdf files. • Backup Compression – Occurs only when data is backed up Much More than Just Great DBA’s

Data Compression • Row Level = simplest method of compression. – Reduces the amount of metadata used to store a row. – Uses less CPU cycles to implement. • Page Level = higher level of compression – Higher level of CPU usage Much More than Just Great DBA’s

Data Compression - Implementation • Implemented through SSMS Much More than Just Great DBA’s

Data Compression - Implementation • Wizard interface, estimates savings. • Caution should be used when implementing in production Much More than Just Great DBA’s

Resource Governor • Implementation is straightforward. • Specific security account (DAC) needs to be created. • Implemented with T-SQL • Improper configuration can cause severe performance issues. • Takes effect when a “Resource Contention” occurs Much More than Just Great DBA’s

New Data Types – Date and Time • DATE - Stores date only in YYYY-MM-DD format. • TIME -Stores time in hh:mm:ss.nnnnnnn format. • DATETIME2 - More precision than existing DATETIME type. • Format is YYYY-MM-DD hh:mm:ss:nnnnnnnm • DATETIMEOFFSET - Similar to DATETIME2, stores Time Zone Information New Data Types – FILESTREAM • Stored in NTFS file system • T-SQL Insert, Update, Deletes operations can be used on datatypes. Much More than Just Great DBA’s

New Data Types – Spatial • Implemented as .Net CLR data type • Conforms to Open Geospatial Consortium standards • Indexes are spatial, stored as a grid based hierarchy • GEOGRAPHY – Stores ellipsoidal data (Longitude and Latitude) • GEOMETRY – Stores planar data (X, Y Coordinates) New Data Types – HIERARCHYID • Implemented as .Net CLR data type • Represents node position in a hierarchical structure Much More than Just Great DBA’s

Performance Data Collector • Management Data Warehouse • Server Activities acts as central repository • Performance Reports • Data Collection Sets • Easy Wizard Configuration • Disk Usage • Scheduled jobs run on regular • Query Statistics basis Much More than Just Great DBA’s

Performance Data Collector • Different configurations for each Data Collection Set • Built in reports for each Data Collection Set • Can be customized Much More than Just Great DBA’s

Transparent Data Encryption • Encrypted in both Memory and on Disk • Key based, allowing for a finer level of security • Encrypts entire database • Easy to administer • Resource requirements are minimal Much More than Just Great DBA’s

SQL Server Audit • Granular, captures SELECT, INSERT, UPDATE, DELETE, REFERENCES and EXECUTE • Uses Extended Events engine, increased speed • Capture and view audit results • Audits at the instance or database level • Audits multiple activity types. • Stores audit events to file • Easy to implement using SSMS Much More than Just Great DBA’s

SQL Server Audit • Create a new audit with SSMS Much More than Just Great DBA’s

SQL Server Audit • Name the audit • Choose items to be audited. • Each audit appears in SSMS Much More than Just Great DBA’s

Extended Events • Generic event handling system • Captures, stores and acts on troubleshooting SQL Server, Windows, and applications. • 254 events can be captured from SQL Server • Correlates SQL, Windows, and Application events • Supports SQL Auditing. • Implemented with T-SQL • Handled by the Event Engine • Common format con be combined with different tools • Less overhead than other tools Much More than Just Great DBA’s

Change Data Capture • Captures and records Insert, Update, and Delete activity. • Data is stored in a format that can easily be consumed by an application. • Data can then be used to synchronize an OLAP server. Much More than Just Great DBA’s

PowerShell • Part of Windows, SQL 2008 ships with PowerShell snap-in • Built on .Net framework 2.0 • Powerful scripting that replaces Kix, Perl, VBScript Much More than Just Great DBA’s
