2 Topics Trends in Database Management IBM s Investment in Database Management New Products New Features Day 1 support for new releases of DB2 for z/os Combined technology of products How-to Examples ALT Command DB2 10 Examples Adding non-key column in index Inline LOBs Online Schema Evolution Enhancements Temporal Tables And more Further product enhancements Calling stored procedures, more masking options, RUN SQL from EDIT Summary and Questions 2

3 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 3

4 IBM Investment Areas for Database Management Data Growth & Complexity Productivity & Efficiency Automation & Standardization Continuity & Resiliency 4 Data Growth & Availability Managing large volumes of data while ensuring high degrees of availability and performance Supporting the changing needs of applications and data Productivity and Efficiency Doing more with less personnel Fewer skilled personnel required to perform complex tasks Reducing the learning curve with more intuitive features and products Automation & Standardization Reducing repeated tasks, manual effort and error Ensuring consistency at company level Continuity & Resiliency Ensuring data integrity Ensuring Day-1 support of new versions of DB2 for z/os

5 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 5

6 Product Enhancements (not related to DB2 10) In this section. ALT command Autonomic Operations 6

7 ALT - The new change dialog 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 7

8 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

9 ALT - The new change dialog - Example ALT against a table Make changes to the table Manage primary key definition Manage partitioning ADD or REL to alter additional objects 9

10 ALT - The new change dialog - Example 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

11 ALT - The new change dialog - Example 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

12 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

13 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

14 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

15 DB2 10 Support in DB2 Administration Tool In this section. Inline LOBs Online Schema Evolution Temporal Tables Security Enhancements And more 15

16 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

17 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

18 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

19 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

20 Inline LOBs - Example Alter the table to convert to or add a LOB column DB2 Object Comparison Tool Inline LOB column length can be changed UDT with inline length can be compared Inline length can be ignored 20

21 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

22 Online Schema Evolution - Example Alter the table space or index Change an attribute 22

23 Online Schema Evolution - Example 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

24 Online Schema Evolution - Example New Pending Changes dialog Can view all or be selective 24

25 Online Schema Evolution - Example New Pending Changes dialog Many commands available to interrogate and manipulate the pending changes DROP to remove all UTIL to implement all DB2 Object Comparison Tool 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

26 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

27 Temporal tables - Example 27

28 Temporal tables - Example The base table has columns with temporal attributes Q AS ROW BEGIN R AS ROW END X AS TRANSACTION START ID 28

29 Temporal tables - Example The history table has the same columns but without temporal attributes 29

30 Temporal tables - Example 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

31 Temporal tables - Example Alter the table ADD PERIOD to add the SYSTEM_TIME or BUSINESS_TIME period 31

32 Temporal tables - Example Alter the table ADD VERSIONING Choose the table to become the history table 32

33 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

34 Row Permissions and Column Masks - Example 34

35 Row Permissions and Column Masks - Example Row Permissions Many line commands to manage a row permision 35

36 Row Permissions and Column Masks - Example Column Masks Many line commands to manage a column mask 36

37 New Privileges From the GRANT panel (ADB2G) Option GZ to GRANT the new privileges Option RZ to REVOKE the new privileges 37

38 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

39 Additional NEW Feature Support (Non-DB2 10) 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

40 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 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

41 Call a stored procedure from Admin - Example 41

42 Call a stored procedure from Admin - Example Provide values for the input parameters 42

43 Call a stored procedure from Admin - Example Upon return, view output parameters Result sets can be shown 43

44 Call a stored procedure from Admin - Example Showing a result set from a stored procedure call 44

45 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

46 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

47 Single character masking - Example SINGLECH:_,+ NAME:ADMIN+ *,ADMIN+_FL* Original object: ADMIN_TASKS 47

48 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

49 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

50 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 50
