DB2 11 Performance Improvements - Exploited

* - Coming soon. Get refreshed at GA

Support for indexes that exclude NULL keys Improve the performance of an index by excluding NULL keys from anindex to reduce its size.

Buffer pool enhancements Several buffer pool enhancements help to improve performance bycontrolling the size of a buffer pool.*

Performance improvements for the LOAD utility Reduce the elapsed time of some LOAD utility jobs by using parallelism inmore situations

Expanded RBA and LRSN log records The RBA and LRSN log records are expanded from basic 6-byte format toextended 10-byte format.

Improved access path reuse with warnings APREUSE(WARN) bind option improves the ability to reuse existing accesspaths.

Free space management enhancements Reserve free space in table spaces for use only by UPDATE operations.*

Automatic cleanup of pseudo-empty indexes Automatically clean up pseudo-deleted index entries and pseudo-emptyindex pages.

Improved performance for BIND and DDL Release resources for long running persistent threads

DPSI performance enhancement Avoid extraneous parallel tasks that use virtual storage


9/59


DB2 11 Availability Improvements - ExploitedOnline Alter Limit key Alter the limit keys for a partitioned table space without impacting data

availability.

Online REORG improvements Automatic creation of mapping tables

Work file database enhancements Alleviate storage shortages before application failures occur

Governing of parallel processing by utilities Manage the amount of parallelism to manage processor resources


10/59


DB2 11 Ease of Use Improvements - ExploitedImproved data validation in DSN1COPY Prevent data corruption by automatically validating the target data set.

Alter limitkeys for materialized query tables ALTER TABLE rather than DROP/CREATE to change MQT limitkey values

Improvements to DROP PENDING CHANGES Removing pending change also removes AREOR status

DB2 11 Security/Regulatory Compliance - Exploited

Exit authorization checking Provides access to ACEE of the package owner for authorization checks.


11/59


DB2 11 New Application Features - ExploitedExplicit period specification on views Extend temporal support to views

Improvements to querying temporal tables Support for two new special registers allow retrieving data from differenttemporal tables without modifying the SQL.

XML support for cross loader function Use LOAD with INCURSOR to move XML data to local or remote tables.

Support for user-defined GLOBAL VARIABLES Share relational data between SQL statements without application logic

Support for arrays Exchange long lists of values with the data server, and compatibility withDB2 LUW

Enhancement to the LIKE predicate Ignore blanks at the end of fixed length strings


12/59


Other DB2 Features delivered by AOCCancel thread FORCE option Includes full syntax support for Cancel Thread

REORG TABLESPACE RECLUSTER Specify to unload data by clustering order during REORG

REORG TABLESPACE LISTPARTS Control maximum number of partitions to be REORGed when usingLISTDEFs

Resource Limit Facility Add support for RLFFUNC column in DSNRLSTxx table

REORG TABLESPACE NOPAD YES Reduce space needed during REORG by unloading varying length columnsto minimum required space

REORG TABLESPACE drain-spec Specify more REORG options than AOC V10.2

RUNSTATS enhancements Add new HISTOGRAM, COLGROUP, RESET ACCESSPATH options


13/59


Strengthening the IBM DB2 Analytics Accelerator EcosystemFull management capabilities including adding/removing Accelerators

Full management capabilities from ISPF interface

Change management support for reloading the data after a changes was made is optional

Data currency info of when data was last loaded into the Accelerator. Can be used Real-timestats to help decide if refresh of the data is needed

Enabeling Multitarget Batch & Online changesSupport for more object types during schema changes

Supporting the enterprise with multi-target change managementSimplify the process of distributing changes to multiple targetCentral status collection to manage and monitor changes for each target

Can ignore changes to add/drop clone tables in DB2 Object Comparison Tool

16/59


DB2 Admin & Compare Multi-Target Change ManagementHow do you distribute and track changes to each of your

environments?

Submit multiple jobs? Logon to each target?

What if object names are different? Which target has the change applied?

Solution Multi-Target Change Management in 3 steps

1. Register a multi-target change once on a central system

2. Easily distribute the change to individual targets or a group of targets Automatically via DRDA*

Register to remote systems change management database

Status updates flow back to the central system

Optionally include masking at each target to adjust for naming differences

3. Each targets status and the overall status is reflected on the central system

One view of where the change has been deployed and applied

File support is available for non-DRDA systems. Status information can be exported from the target systemand imported on the central system.

DB2 z/OS and Distributive Computing Challenges

Client managementEvery distributed performance problem is a DB2 Connect problem

The DB2 Connect gateway is the excuse for many distributed computing problems

Difficult to understand what is going on inside the mainframe black box (System zcabinets are really black too)

DBAsDon't have access to application and driver configurations

Don't have access to web application server configurations

Have problem understanding which applications programs that are associated with DB2threads

Hang on to DB2 Connect gateways because it is a point of control (Note: no otherrelational DBMS needs a gateway for connections)

Customers perceive DB2 Connect gateways providing connection control, but areactually very limited in abilities

Usually don't have ability revise WLM connection informationSystems programmers

Can't control and don't trust distributed application program or web server setup

Difficult to education all of the distributed teams about criteria used to prioritize work

User Id. Is the only trusted connection property

Database Downtime Affects Your Business

Time consuming, rarely used, manualbackup/recovery procedures dont scaleas data volumes grow

Inability to backup all data because of

shrinking maintenance windows andgrowing data volumes

Difficult to get complete databasebackup without production impact

Modernization: No longer have theluxury of doing backup and recoveriesthe traditional way

Average cost of database downtime$1.5M USD/year

Revenue at risk

Customer satisfaction declines

Missed services level agreements

Brand damage and loss of goodwill

Customers desire immediate

gratification

Recovery DBA scenarios


40/59


Oh NO !! Have you ever..

Have you ever.. Incorrectly made application

changes?

Accidentally dropped an object?

Now what? Are you prepared?

Reversing schema changes can bemanual, error prone and time

consuming.

Dropped object recovery can be ahuge nightmare!


41/59


Back Out Complex Schema Changes

DBA selects method of loading data:

unload/load method

DSN1COPY methodIf unload/load, DBA needs to unload data:

Unload from current base table Unload from an image copy

Drop Table

Recreate table minus the implemented changes

Load data into table

LOAD utility DSN1COPY

If DSN1COPY, DBA needs to rebuild indexes

Execute RUNSTATS on table/indexes

Recreate views

Grant appropriate authorities on tableRecreate RI

Run CHECK utility to validate data integrity

Recreate any associated triggers

Bind packages that were invalidated
