Trends in Database Management Data growth puts pressure on IT infrastructure, SLAs, staff, and performance

According to IDC, the amount of data is exploding. Structured data is growing 32% per year, unstructured data is growing 63% and replicated data is growing 49%. Companies are compelled to take the right steps to protect

their valuable data and maintain high database availability

• Average data growth per year is approximately 30%• Large critical application data growth rate is > 50%

In the last 10 years the number of objects needing performance

management has increased:

• The number of objects that need management has increased 3X• the number of objects per DBA has increased 4X

Focus on reducing CPU and elapsed time

Running multiple databases on a server has become the norm

90% of customers have more than one DBMS Resource/skill issues, consistent administration efforts, increased cost in administration, greater need to automate routine operations

How is the investment realized by IBM in the Database Management space?

New features in existing products that address pain points for customers– Ex: ALT command in DB2 Administration Tool– Ex: Autonomic operations

Day 1 support for new releases of DB2 for z/OS– Ex: DB2 10 for z/OS

Combining strengths of existing products to take advantage of new features– Ex: Support for DB2 10 utilities in DB2 Administration Tool – Ex: DB2 Administration Tool is integrated with other DB2 tools creating additional

functionality with product-specific line commands for table editing, SQL cost analysis and path check analysis. Through its DB2 tools launch pad, DB2 Administration Tool is the central access point for any tool with an ISPF interface. SQL Performance Analyzer and the DB2 Table Editor can seamlessly be invoked for advanced SQL tuning and row editing

New Products that take advantage of existing investment to provide options for those customers with special needs

– Ex: DB2 Sort for z/OS

Product Enhancements (not related to DB2 10)

In this section….

–ALT command

–Autonomic Operations

6



ALT line command available to modify

– A table

– A table space

– A database

– An index

– A view

– A foreign key

Replaces ALC, RDEF TS, RDEF IX, RenDB

A single master dialog (hub) for changing objects

One process for all objects and object types

Common processes with Object Compare and Change Management

ALT - The new change dialog

7



ALT - The new change dialog - Example

ALT line command is

common to all object types

Dedicated dialog for each

object type

Analysis to determine

change implementation

Optional utilities

AL line command :

– ALTER statements only

– No utilities

– One object at a time

8




ALT against a table

Make changes to the table

Manage primary key

definition

Manage partitioning

ADD or REL to alter

additional objects

9




The “hub” of change

Add additional tables

Alter related objects

ALTER primary command

proceeds to build batch jobs

OPTIONS include

– Running online or in

batch

– Building a recover

process

10




Full control of options for the

jobs produced

Single panel & process for

all objects and types

Build as a batch job or a

work statement list (WSL)

Choose optional utilities

11



ALT – Change for the power user

One common interface and process

– Be more productive, sooner (shorter learning curve)

– Common terminology and behavior to OC and CM

NOPAD - Unload utility option to unload data without “white space”

– Reduced DASD usage and CPU processing

– Product disables NOPAD if it cannot be used

– Set it and forget it

Exploit parallel job or work statement list processing

– Multiple unload jobs

– Single DDL jobs

– Multiple LOAD jobs

Exploitation of DB2 Sort for z/OS v1.1 using the DB2 utilities

12



Autonomic Operations

Product performs operations automatically in response to conditions

Improve availability and lessen DBA work

Online alters:

– Respond to the event (SQLCODE610)

– Prompt to run the appropriate utility

13



Autonomic Operations

Batch alters (ADBTEP2):

– AUTOCHECK

– Run CHECK against dependent objects

– AUTOREORG and AUTOREBUILD

– Respond to the event (SQLCODE610)

– STOGROUP VCAT changes or BUFFERPOOL changes

– Optionally implement DB2 pending changes (DB2 10)

– AUTOREBIND

– Packages/Plans become invalid when referential integrity is added

– Affected packages and plans are identified and rebound

14



DB2 10 Support in DB2 Administration Tool

In this section….

– Inline LOBs

–Online Schema Evolution

–Temporal Tables

–Security Enhancements

–And more…

15



Additional non-key column in an index

DB2 10 enhancement

– Application needs an index to enforce uniqueness

– Another index exists with same columns plus additional columns

– Additional DASD space, CPU, I/O, … to maintain and use additional index

ALTER INDEX … ADD INCLUDE COLUMN (column)

– Eliminates the need for the additional index

– Original (non-include) columns maintain uniqueness

– Index has the included column values to improve query performance

– Warning: Index is put in REBUILD pending and unavailable for updates

Autonomic operations will help remedy this

16



Additional non-key column in an index - Example

AL the index

Add a column

Choose to add as an include

column

ALTER statement will be

built and performed

17



Additional non-key column in an index - Example

Index is in REBUILD-pending

Integrated autonomic

operations help to resolve

the state

DB2 Object Comparison Tool

– Included columns can be

added from source to

target

– Included columns can be

removed from the target

– Included column

differences can be

ignored

18



Inline LOBs

DB2 10 Enhancement

– Prior: A LOB value is housed in a separate table and table space

– DB2 10: A portion of the LOB value can be stored with the base table data

– LOBs of “smallish” size may fit entirely

– Performance improvement

– Inline portion can be used in an index on expression

19



Inline LOBs - Example

Alter the table to convert to

or add a LOB column


– Inline LOB column

length can be changed

– UDT with inline length

can be compared

– Inline length can be

ignored

20



Online Schema Evolution

DB2 10 Enhancement

– Use ALTER to make changes to :

– BUFFERPOOL size

– DSSIZE

– SEGSIZE

– MAXPARTITIONS

– Changes are pending until a REORG or REBUILD is performed

– Advisory-REORG or Advisory-REBUILD

– DB2 Pending Changes can be dropped

– Benefits:

– Attribute changes done via ALTER rather than DROP/CREATE

– Can make changes prior to the batch window

21



Online Schema Evolution - Example

Alter the table space or index

Change an attribute

22




Online - Index is in Advisory

Reorg pending state

Integrated autonomic

operations

– Identifies the condition

– Offers options to resolve

the state

ALT

– Pre-existing pending

changes will be retained

or implemented

23




New Pending Changes

dialog

Can view all or be selective

24




New Pending Changes

dialog

Many commands available to

interrogate and manipulate

the pending changes

– DROP to remove all

– UTIL to implement all


– Pending changes from

source and target are

logically implemented

prior to source-to-target

compare

– Pending changes can be

ignored (won‟t be

logically implemented

25



Temporal tables

DB2 10 Enhancement

– Retain historical copies of a row – SYSTEM_TIME

– When updated, created and deleted

– Maintain rows based upon business-determined periods - BUSINESS_TIME

– Can query data “as of” a point in time

26



Temporal tables - Example

27




The base table has columns

with temporal attributes

Q – AS ROW BEGIN

R – AS ROW END

X – AS TRANSACTION

START ID

28




The history table has the

same columns but without

temporal attributes

29




Alter the table

ADD PERIOD

– Add the SYSTEM_TIME

period attribute

ADD VERSIONING

– Begins versioning the

data on DML

DROP VERSIONING

– Removes versioning of

data

30




Alter the table

ADD PERIOD to add the

SYSTEM_TIME or

BUSINESS_TIME period

31




Alter the table

ADD VERSIONING

Choose the table to become

the history table

32



Security Enhancements

DB2 10 Enhancement

– Provide row-level security by predicate usage - who can view this row

– Provide column-level value security - mask sensitive information

– More granular levels of privileges

– Eliminate object-access requirements for certain functions (Eg. EXPLAIN)

– Separate object security and object administration roles

– Comply with security policies, regulatory compliance, reduce business risk

33



Row Permissions and Column Masks - Example

34




Row Permissions

– Many line commands to

manage a row permision

35




Column Masks

– Many line commands to

manage a column mask

36



New Privileges

From the GRANT panel

(ADB2G)

– Option GZ to GRANT the

new privileges

– Option RZ to REVOKE

the new privileges

37



Additional DB2 10 Support in DB2 Administration Tool

Hash access support

UTS support for MEMBER CLUSTER

Flashcopy enhancements

XML Modifiers

UNLOAD XML in binary

TIMESTAMP WITH TIME ZONE

And more…

38

In this section….

–Calling a stored procedure from within Admin Tool

–More masking options

• Including single character masking

–Executing SQL from EDIT

–Backup DDL prior to WSL Run

–SQL Only generated of WSL or JCL

39



Call a stored procedure from Admin

Develop and testing stored procedures prior to writing an application

The product issues SELECT SYSPARMS to get the input parameters for the SP

Enter each input parameter, up to 32760 bytes long

Input parameter is validated against its data type

Call primary command to call the stored procedure

Result are displayed - output parameters and multiple result sets

40



Call a stored procedure from Admin - Example

41




Provide values for the input parameters

42




Upon return, view output parameters

Result sets can be shown

43




Showing a result set from a stored procedure call

44



Masking enhancements

Can mask new and more granular names:

– row permission, column mask, constraint, sequence, synonym, alias, view

Can mask new and more granular schemas:

– row permission, column mask, SET PATH, trigger, UDT, sequence, stored procedure,

UDF, alias, view

New additional mask items: registered XML schema name, WLM environment, location,

New overwrites:

– hash space, inline LOB length for tables, inline LOB length for distinct types, AUDIT,

CLOSE

Single character masking

45



Single character masking

A complement to the existing multi-character masking feature

A new entry in mask data set to indicate single character masking

Optional escape character to treat mask character as a literal

46



Single character masking - Example

SINGLECH:_,+

NAME:ADMIN+__*,ADMIN+_FL*

Original object: ADMIN_TASKS

47



Run SQL from EDIT

ISPF Editor is now used for

– Option 1 from panel

ADB22

– When using the „+‟

primary command

EXEC command runs the SQL

Error information is presented

within the EDIT session

Fix and retry while staying

within EDIT

48



Backup DDL prior to WSL Run

Option to generate DDL for

dropped objects and their

dependents

GEN function is run as first

step in the process

Ease of use – other run

options now reside on single

panel

49



SQL Only generated of WSL or JCL

Option to build all processes

or just DDL (no utilities)

Available in change

processes – ALT, CM and OC

Ideal for test-only or other

environments where

retaining data is not

necessary
