EB-6332 > 0611 > PAGE 1 OF 5

Todays huge and complex data warehouses

demand ever increasing levels of automa-

tion and management. And that means

you must have all the tools and technolo-

gies right at your fingertips to be able to

view and analyze system performance

whenever and wherever necessary. What

you need is a true command center, a

centralized location where you can monitor

Teradata Databases and visualize real-

time performance and historical trends.

Thats why Teradata Corporation, the

global leader in data warehousing and

analytics, has developed the Teradata

Management Portlets bundle: to give

you everything you need for analysis and

display of performance and database

utilization information through leading-

edge portal interfaces. The portlets are

easy to use and are accessible from select

Web browsers by managers, business

intelligence (BI) users, and database

administrators (DBAs).

Teradata Lowers Cost of

Ownership

Teradata Management Portlets bundle

offers you a powerful and versatile collec-tion of integrated database management

portlets and provides you with real-time

insight to handle your increasingly com-

plex production environment. It allows

you to efficiently process your most critical

work and keep your entire enterprise

running at peak performance. Its a

combination that translates to less work

for administrators and a lower total cost

of ownership (TCO) than other data

warehouse databases on the market today.

Easy Deployment and UseTeradata Management Portlets are built

on the market leading Teradata Viewpoint

portal management framework. Teradata

Viewpoint, the foundation for all Teradata

management activities, delivers a web-based

interface common to all the management

portlets, making it easy to deploy and use

new portlets with minimal training.

Among Teradata Viewpoints features are:

> Consistent user experience across all

Teradata management portlets.

> No client tool installation; all portlets

are accessible from any web browser.

> Performance data are collected in a

local Teradata Viewpoint appliance

cache to eliminate the impact on the

Teradata Database.

> Rewind enables you to rewind a

portlet to any previous time slot

from previously collected data.

Performance Analysis and

Problem Resolution

Teradata Management Portlets allow for

query, manipulation, and display of

actions against current and historical

performance and usage data to allow you

to quickly identify and resolve resource

bottlenecks and ensure your Teradata

systems are running at peak efficiency.

With Teradata Viewpoints flexible portal

management framework, you can organize

and group the portlets columns and tabs.

The portlets provide real-time data and

trend charts showing resource consump-

tion over any time duration contained in

the collections.

actions. Use to monitor alerts over different periods of time.

Query SpotlightDBA or

BI User

Analyze problem queries by viewing completed queries that exceeded the thresholds you set.

Users can view individual queries of interest as a line graph over time and against a variety of

metrics. The Snapshot tab displays query data at any point in time. View general information

about a query, inspect a query as a line graph using the date-range slider and time marker, or

set a date and time in the rewind tool bar.

Query MonitorDBA or

BI User

View information about queries running in a Teradata Database system to quickly spot prob-

lem queries. Users can analyze and decide whether or not a query is important, useful, and

well written. After identifying a problem query, correct it by changing the priority or workload,releasing the query, or aborting the query or session. Filter queries in all session views or set

thresholds for any column when the threshold is exceeded.

Helps user determine types of utilities that are running most frequently on the system and

then set utility limits.

Node ResourcesManager

or DBA

Monitor physical and virtual resources to locate over- or under-utilized resources. Isolate

performance or system issues based on CPU and other systems resources.
