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
Syncsort Confidential and Proprietary - do not copy or distribute
“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!”

11. Migrating IMS to DB2
Without Rewriting Applications

12. 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. 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!!

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

DL/2: Transparent Data Migration to DB2®
✓ Migrate IMS Segments to DB2
tables without making any
application 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

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

Why the Transparency Approach?
Syncsort Confidential and Proprietary - do not copy or distribute
• 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. 25
