Who we help

Application Developers and DBAs typically need help during

three stages of development:

Coding

Testing

Deployment

Today’s environment has created new challenges for developers

and DBAs

Living with reduced resources and timeframes

Developing apps that meet both user requirements and batch windows

Meeting increasing user demands

Dealing with increased privacy regulations

Focused on helping application developers and DBAs eliminate

performance and reliability problems with DB2 for z/OS applications

How we help

Deploy

Test

CodeCode DB2 for z/OS SQL statements to work properly and perform optimally

Test all DB2 applications as quickly and thoroughly as possible

Deploy DB2 applications without painful performance or application surprises (or 2:00 am phone call surprises)

Code

Building a better DB2 coding experience

Need to code and verify proper SQL statements

Need to develop internal standards for SQL coding

Make SQL coding enforcement an automated process

DB/IQ-QA

Test

Building a better DB2 text experience

Access to referentially intact subsets of DB2, VSAM and sequential test data

Inability to de-identify sensitive data

Developers cannot retrieve their own test data when they need it

Painful, single-threaded testing procedures slow everyone down

Inability to retest DB2 application programs with identical data at a later time

Building and maintaining multiple DB2 test beds, CICS or IMS regions takes excessive time & resources

TestApplication Testing Challenges

TestBase – Faster, Better, Safer DB2 testing

Quickly extract RI related

data

Automate most common

test data tasks

Generate test data from

scratch

Retrieve and refresh test

data whenever needed

Test together and

independently

(vs. One Developer At A

Time) using Data Slicer

Deploy

Code

Test

TestBase Extracts RI Intact Subset (DB2 or Application RI) Masks Data BEFORE Loading Into Test Easy To Use Result: Faster, Better & Safer Test Data

TestBase is faster –

complete testing workbench that enables DBAs to:

TestBase – Faster, Better, Safer DB2 testing

Patented Data Slicer allows multiple

users to test with their own copy, or

“Slice”, of data

TestBase Compare Report quickly

validates that changes worked

correctly

TestBase also can provide powerful

regression Compare Report that

proves that application is processing

data properly

Batch Analyzer

What is the most expensive DB2 Job during the last 24 hours? Job HRBKUPQ2 used more than 38% of all DB2 CPU during this time!

Batch Analyzer can quickly locate any DB2 Jobs that might encounter excessively long DB2 ROLLBACKs if they fail.

SoftBase Deployment Solutions

Allows developers to quickly

insert COMMITs and

CHECKPOINTS into batch job

streams - in some instances

without even editing your

programs.

COMMITs will often speed up

DB2 batch programs and also

free up DB2 resources

Allows developers to quickly

restart any abended production

job from the point of failure
