• 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

acts as central repository

• Data Collection Sets

• Disk Usage

• Query Statistics

• Server Activities

• Performance Reports

• Easy Wizard Configuration

• Scheduled jobs run on regular

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
