Agenda

• EZ-DB2

• CPU workload-centric optimization for DB2

•DL/2

• The best approach to migrate IMS data to DB2

• Standardize application change & enhancement in SQL

•Q&A


CPU Workload-centric Optimization for DB2

5

DBA Challenges

Growing volumes of dynamic SQLs impacting the environment

– distributed Java and .Net applications

– ad hoc query reporting tools

– packaged applications

Ensuring SQL performance meets SLAs and other service-quality goals

Avoiding excessive CPU consumption

Avoiding or postponing costly upgrades

Operating with reduced staff levels and less than adequate optimization tools


6

What is EZ-DB2?


• Leading solution for DB2 SQL workload performance optimization on z/OS

• Saves DB2 CPU resources

• Improves performance

• Reduces the impact of application and environmental changes

7

What EZ-DB2 Does…

Captures and consolidates static and dynamic SQL including SQL originating from distributed environments

Reveals the “hidden” SQL statements that consume the most system resources.

Automatically and intelligently derives the optimal index design based your actual SQL workload and production data characteristics.

Anticipates how environmental changes such as migration of application changes from Dev/Test to production may affect performance and resource consumption.

What Customers Say About EZ-DB2


“We were able to reclaim the cost of EZ-DB2 in production CPU savings within 5 months of installing the product and have gone

on to see significant extra savings in the following months.”

“In just over a month using EZ-DB2, the Company identified in excess of 35% DB2 CPU savings. These savings were eventually

extended to 50%. CPU reduction was accomplished with no adverse impact on application performance.”

“Just last month EZ DB2 identified an SQL that decided to go south after running for several months ‘with no problems’ and was pegging out both of our machines in data sharing. Quick 5 minute trace to identify bad SQL, add an index and minor SQL change and problem gone. EZ DB2 to the rescue!”

10

Why EZ-DB2?

✓Improve performance and reduce DB2 resource utilization

✓Reduce CPU costs and improve throughput

✓Improve system stability and delay CPU upgrades

✓Avoid potentially detrimental changes to applications and program SQL

✓Maintain DB2 system integrity when making environment changes or migrating applications between subsystems

✓Ensure correct index design for new and existing applications

✓Automated optimization of DB2 index designs


Migrating IMS to DB2Without Rewriting Applications

12

IMS – Its been a great workhorse but…

IMS is an aging hierarchical platform that provides minimal scope

for modernization

Rewriting these applications is expensive

Rewrite projects in many cases overrun both in time and cost

High risk involved in a “big bang” rewrite approach

Replace with 3rd party COTS software

Does not fully meet the requirements of the business

Requires significant work to retro fit to mirror existing

functionality

Significant cost in both software and services to implement


13

Who is going to support your IMS applications?

IMS Skills

Staff that wrote original applications and support these

aging systems are heading off to retirement

In many cases, reliant on 3rd party vendors to support IMS

Skills drain to support legacy applications is a significant risk

to the enterprise

On-going IMS costs

IMS MLC costs, IMS support tools, IMS Upgrade costs

IMS DB DBA Support and Applications Support

These costs will continue month on month, year on year and

IBM and your IMS tools vendor knows this!!


14

The low risk alternative – Syncsort DL/2

Migration to DB2 without touching application code

This provides a low risk alternative to eliminate IMS DB and 3rd

party support tools and significantly reduce on-going costs

Significantly reduces the reliance on IMS skills

Opens up data in a DB2 relational model to support new business

initiatives

Removes requirements for any current data replication to DB2

Enables application change to shift to SQL/DB2 skills

Over time provides an orderly move toward native SQL/DB2

applications, if required


15

DL/2: Transparent Data Migration to DB2®

✓Migrate IMS Segments to DB2 tables without making anyapplication changes

✓ Eliminate IMS DB and 3rd party IMS support tools

✓Reduce overall application maintenance tools

✓ Syncsort DL2 is not a replication tool, it is a replacement for IMS DB


16

What Do We Mean by Transparent Data Migration?

• No modifications, compiles, recompiles, link-edits of existing

application programs

• Migrate at your own pace – one file at a time, multiple files

• Environmental changes for batch JCL and CICS can be made in non-

disruptively in advance

• Simple switch between IMS/VSAM and DB2 for application testing

• Fallback capability

• Easiest and fastest route to DB2 and value delivery

LOWEST RISK MIGRATION APPROACH – PROVEN TIME AND TIME AGAIN

DL/2 at a Major Swiss Bank

• Global Foreign Exchange platform – 3rd largest in the world

• Rewrite project minimum 5-7 years

• Costs of IMS DB in excess of $2m per annum

• High risk involved in “big bang” rewrite approach

• DL/2 initially rejected in favour of a re-write

• After 18 months rewrite project stalled

• Mainframe infrastructure insist on a DL/2 pilot

• Pilot successful and full project initiated and completed in 8 months

with elimination of IMS DB and IMS tools licensing


20

DL/2 at State of Florida DOC

• Florida DOC – Inmate management system for the entire State

• Cost reduction and on-going application modernization

• Requirement to clean up outdated information and provide modernization

platform in DB2

• Legislature unable to approve funding for multi million $ rewrite

• DL/2 again provides modernization platform with minimal risk

• IMS databases migrated to a normalized DB2 design with significant data

typing and re-engineering

• Application change requests now delivered via SQL/DB2 skills

• Significant cost reduction with elimination of IMS DB and IMS tools

licensing


21

DB2 Design Summary


• Each IMS segment maps to one DB2 table

• IMS concatenated key becomes DB2 primary key

• DB2 referential integrity ensures hierarchic integrity

• User defined DB2 table names, column names

• Optionally, DB2 design based on copybook/record definition

• Data transformation using built in conversion facilities• Date fields

• Numeric fields

• May require data cleansing

• Different design models can be deployed for different databases, even down to the individual segment level

22

Typical Migration Project


• Databases grouped by application/size/complexity for optimal testing

• Primarily 3 main project phases:

Database Group 1

Database Group 2

Database Group 3

TIME

Database Group n

Database mapping usually performed by Syncsort

23

Syncsort Migration Services


• Free of charge DBD and PSB review service

• Proof of concept

• Mapping and migration service

• Onsite support for production cutover

24

Why the Transparency Approach?


• NO application program changes are required

• LOWEST RISK migration strategy – bite-sized chunks

• REDUCED COSTS through elimination of IMS DB and BMC tools licenses

• SIMPLIFICATION of DBA support through DBMS convergence

• CHOICE of migration methods to meet differing requirements

• Simple, rapid method to reduce costs very quickly

• More measured method to meet DB2 design objectives

• A combination of both

• Simple method first, measured method later

• MINOR JCL changes (which can be made in advance)

25

DL/2 Transparent Data Migration


• Eliminate IMS DB and IMS tools License costs with NO changes to

application code

• Support Legacy Modernization initiatives

• Reduce Risk as IMS DBA and Programming skills head for retirement

Industry Leader in Mainframe Software Products
