Poorly performing databases can lead to end-user productivity issues, system
downtime and even lost revenues. Complex enterprise systems running on multiple
platforms place increased demands on the database and the DBA. Manually identify-
ing, diagnosing and resolving database problems in such complex environments is
nearly impossible. Additionally, many of the database management tools available
today require DBAs to use multiple platform-specific tools to solve these problems —
further impacting productivity.
Quest Central™ for DB2 provides today’s DBA with a powerful and comprehen-
sive database management tool that supports multiple platforms all from one inte-
grated interface. Each Quest Central component offers distinct functionality focusing
on critical aspects of DB2 database management. Available components include:
Performance Monitoring, Database Administration, Space Management and
SQL Tuning. Quest Central provides consistent features regardless of database plat-
form, making it easy for mainframe DBAs to manage DB2 on Unix or Windows, or
vice versa.
Quest Central’s components are tightly integrated to allow users to identify,
diagnose and resolve database problems seamlessly. For example, if the Performance
Monitor identifies a poorly performing application and determines that a particular
SQL statement is causing excessive CPU consumption, simply invoke the SQL Tuning
component from within the Performance Monitor. The tuning component may
suggest an additional index, and then you can create the index and immediately see
the results.
The SQL Tuning component provides intel-
ligent advice on how to tune offensive SQL
statements and quickly improve response time.
The advice examines every part of the SQL
statement and offers informed tuning recom-
mendations. With the click of a button, the com-
ponent then rewrites the SQL statement to
implement the selected advice.
Quest Central provides a robust tuning
environment that lets you work with multiple
versions of a base SQL statement to easily
improve queries. The scenario capability keeps
the target statement in its original form with
modified versions placed in separate scenarios.
Scenarios can be based on manual statement
modifications or generated from the compo-
nent’s tuning advice.
A powerful compare engine allows for comparison across all the scenarios so
you can choose the tuning solution that provides the best overall results. The com-
pare engine immediately displays the scenario with the lowest cost in terms of CPU,
I/O or elapsed time. In addition, access path and data results are compared to
ensure the SQL statement continues to return the desired results.
The SQL Tuning module is integrated with other Quest Central components to
accommodate your workflow. Easy access to the Space Management module allows
update of DB2 UDB statistics that have been identified as missing or inaccurate.
Database Administration integration allows for index creation directly from the
tuning module.
Robust Utilities for Everyday Tasks
Accessible from all Quest Central compo-
nents are the basic utilities every DBA needs to
get through their day. A built-in SQL editor and
query builder are only a click away, eliminating
the need to jump to external command prompts.
A flexible scheduler enables you to run scripts
after hours or at predefined intervals. Plus, a
configuration manager allows you to catalog
nodes and databases without having to leave

The Integrated Solution for DB2 Management
Quest Central for DB2 provides a thorough solution for database management.
Quality tools that improve DBA productivity, database performance and applica-
tion availability are integrated in one easy-to-use graphical platform. And since
Quest Central is based on an innovative plug-in approach, it is easy to install —
enabling DBAs to react to performance problems faster than ever before. Available
Quest Central components include:
• Performance Monitoring - visually renders the DB2 UDB process model, so
you can observe actual database activity in real time to quickly identify hot
spots within the database and drill into these components to find the source
of the problem
• SQL Tuning - lets you quickly optimize your SQL statements with a complete
tuning environment for DB2 UDB and DB2 on OS/390 and expert advice
• Database Administration - makes it easy to administer and migrate DB2 UDB
database objects and security with purpose-built dialogs, extended alter capa-
bilities and automated scripting
• Space Management - helps you identify and resolve potential DB2 UDB space
problems with exception reporting, space analysis, trend analysis, statistic
collection and data reorganization
Use the integrated SQL editor toeasily build, execute and explaincomplex SQL statements.
Easily compare the executionresults across multiple tuningscenarios so you can identify the most improved statement.

The Space Management module can immediately identify all
space and performance related exceptions in your database with
one concise report. It analyzes exceptions and performs calcula-
tions, then provides intelligent advice for correcting any problems.
In addition, it lets you change space allocation parameters, collect
statistics or reorg tables directly from the report.
One of the top reasons a database responds poorly to requests
for data is fragmentation. A simple request for just one row of data
can require the database manager to issue several physical I/Os.
Space Management’s Table and Index Reorg Exception Reports
identify tables and indexes in need of reorganization. Since one
of several reasons could cause a table or index to be identified,
the intelligent advice will describe the exception with a suggested
resolution. The component also provides the ability to reorganize tables and
rebuild indexes directly from the exception reports. Reorganizations may also be
scheduled for background execution during off-peak hours to minimize the impact
on application availability.
Understanding how space allocation changes will affect each object within a
tablespace can be difficult. DB2 EEE only complicates the process since nodes must
now be taken into account. The space calculator exploits EEE features to provide an
intuitive and comprehensive solution for analyzing space allocation and determining
impact analysis.
SQL Tuning with Expert Advice
Effectively tuning your application is vital to maximizing database performance.
Unfortunately, application tuning often gets overlooked due to time and resource
constraints. Quest Central’s SQL Tuning module — available for DB2 running on
Windows, Unix, OS/2 and OS/390 — provides a comprehensive tuning environment
to guide users through the entire tuning process.
The access path display is designed to translate explain information into a format
that is easy to understand. The display also color codes potentially high cost access
steps, so you can focus your attention on areas that yield the highest return from tun-
ing. The SQL Tuning module also offers object statistics to provide pertinent informa-
tion such as number of rows in a table, indexes on a table and columns found in an
index. Many access plans are long and complex, so the SQL Tuning module lets you
display plan details in three different formats for easy navigation and analysis. Each
format lets you step through the plan and visualize the processing order.
to accomplish extended alterations. The analysis engine identifies
all the relationships and permissions that are involved with a
requested alteration and migration and then builds the SQL
script to carry out the change.
When a table must be dropped and recreated to accommo-
date an extended alteration, Quest Central manages the unload-
ing and reloading of table data and ensures that all objects are
restored intact. To ensure successful script execution,
Quest Central provides sophisticated script processing that
includes error handling, checkpoint restart and scheduling.
Quest Central also offers the ability to execute the script remotely
on the database server to reduce network traffic.
Database and object migration is also simplified. Just drag
and drop an object from one server to another. Quest Central can
migrate dependent objects, data and even permissions to ensure
the entire database structure is migrated to the target server. A complete migration
script is generated which can then be executed, saved, or scheduled to execute later.
Managing database security is equally important, so Quest Central provides the
necessary means to stay on top of security requests. DBAs can view and control
permissions from the object, user, or user group level, ensuring that application data
is available only to authorized users.
The Database Administration module is integrated with other Quest Central
components to streamline workflow. While creating or altering certain database
objects such as views and triggers, direct integration into Quest Central’s
SQL Tuning module is available to tune the SQL statements used by these objects.
Comprehensive Space Management
Unmanaged database growth leads to poor response time and eventu-
ally database failure. Quest Central’s Space Management module is a
preventive maintenance solution designed to manage database growth
and data reorganization as well as save DBAs time with powerful
exception reporting.
Quest Central Space Management proactively forecasts and graphs
database growth, giving DBAs the time to plan for increasing the size of a
tablespace and scheduling necessary reorganizations. This component
automatically collects both growth and performance related statistics and
retains this information in a repository, unlike DB2 UDB, which discards
previously collected statistics each time RUNSTATS is executed.
Quest Central™
for DB2
Real-time Performance Monitoring
Quest Central’s Performance Monitoring component empowers DBAs with
everything they need to quickly identify and diagnose performance degradations.
The main display provides an active graphical illustration of the database architecture
with live activity flowing through the DB2 components. Displaying the actual process-
ing architecture of your DB2 instance and database helps you pinpoint the source of
problems as they occur and rapidly resolve them. This display also reveals to the user
how a performance problem in one component affects the other components within
the DBMS.
With Quest Central, you can drill
down to view key database and oper-
ating system metrics associated with
highlighted bottlenecks. This allows
you to quickly gather detailed infor-
mation about client applications, data-
base I/O, SQL statements and buffer
pool utilization. Plus, you can drill
down to operating system metrics
such as processes, CPU, I/O, network,
memory and storage statistics specific
to the database server platform. A full
range of reports and charts provides
detailed information to help pinpoint
any activity that causes bottlenecks.
Performance Monitoring also detects when thresholds are exceeded and sends
warning of impending problems with a visual or audible alert. With these advanced
warnings, DBAs have the time to eliminate bottlenecks before they impact end users.
Complete Database Administration
Too often, database administrators spend a majority of their time piecing
together lengthy, complex scripts to migrate and administer database objects. Errors in
script logic or design expose the application to system downtime or, at worst,
data loss.
Quest Central’s Database Administration component eases the burden of main-
taining and migrating database objects by providing a comprehensive graphical object
management solution. This easy-to-use module allows you to quickly create, drop or
alter database objects to accommodate business and application needs. Extended
object alterations are also available through these dialogs, allowing you to make com-
plex object changes that are not possible using the alter commands native to DB2.
Quest Central does this by automating the extensive research and scripting needed

Poorly performing databases can lead to end-user productivity issues, system
downtime and even lost revenues. Complex enterprise systems running on multiple
platforms place increased demands on the database and the DBA. Manually identify-
ing, diagnosing and resolving database problems in such complex environments is
nearly impossible. Additionally, many of the database management tools available
today require DBAs to use multiple platform-specific tools to solve these problems —
further impacting productivity.
Quest Central™ for DB2 provides today’s DBA with a powerful and comprehen-
sive database management tool that supports multiple platforms all from one inte-
grated interface. Each Quest Central component offers distinct functionality focusing
on critical aspects of DB2 database management. Available components include:
Performance Monitoring, Database Administration, Space Management and
SQL Tuning. Quest Central provides consistent features regardless of database plat-
form, making it easy for mainframe DBAs to manage DB2 on Unix or Windows, or
vice versa.
Quest Central’s components are tightly integrated to allow users to identify,
diagnose and resolve database problems seamlessly. For example, if the Performance
Monitor identifies a poorly performing application and determines that a particular
SQL statement is causing excessive CPU consumption, simply invoke the SQL Tuning
component from within the Performance Monitor. The tuning component may
suggest an additional index, and then you can create the index and immediately see
the results.
The SQL Tuning component provides intel-
ligent advice on how to tune offensive SQL
statements and quickly improve response time.
The advice examines every part of the SQL
statement and offers informed tuning recom-
mendations. With the click of a button, the com-
ponent then rewrites the SQL statement to
implement the selected advice.
Quest Central provides a robust tuning
environment that lets you work with multiple
versions of a base SQL statement to easily
improve queries. The scenario capability keeps
the target statement in its original form with
modified versions placed in separate scenarios.
Scenarios can be based on manual statement
modifications or generated from the compo-
nent’s tuning advice.
A powerful compare engine allows for comparison across all the scenarios so
you can choose the tuning solution that provides the best overall results. The com-
pare engine immediately displays the scenario with the lowest cost in terms of CPU,
I/O or elapsed time. In addition, access path and data results are compared to
ensure the SQL statement continues to return the desired results.
The SQL Tuning module is integrated with other Quest Central components to
accommodate your workflow. Easy access to the Space Management module allows
update of DB2 UDB statistics that have been identified as missing or inaccurate.
Database Administration integration allows for index creation directly from the
tuning module.
Robust Utilities for Everyday Tasks
Accessible from all Quest Central compo-
nents are the basic utilities every DBA needs to
get through their day. A built-in SQL editor and
query builder are only a click away, eliminating
the need to jump to external command prompts.
A flexible scheduler enables you to run scripts
after hours or at predefined intervals. Plus, a
configuration manager allows you to catalog
nodes and databases without having to leave
Quest Central.
