Mainframe DataShare


Replicate pre-relational databases into relational equivalents and liberate legacy data for business Intelligence, analytics, & data warehouse efforts

Benefits of Mainframe DataShareAccesses and shares data from the mainframe, empowering data warehouse, BI and analytics

efforts WITHOUT a migration or mainframe footprint

Reduces MIPS consumption by shifting report functionality off mainframe

Cuts management report delivery time from months to hours

Leverages automated provision of Initial load and ongoing replication of data from legacy database to Oracle, SQL Server or DB2 with confirmation of all legacy data present and accessible in the target database


BATCH OFFLOADING

8 –



Offloading Batch Workloads


Leverages off-mainframe processing power to reduce MIPS and overall cost-of-ownership

Enables mainframe batch processes to be run on physical or virtual infrastructure according to customer preference

Converts procedural batch code to object-oriented Java or C#

Offers four tiers of support that include real-time monitoring, operator services, and guidance

Reduces mainframe MIPS

Offloading Batch Workloads

//SAMPLE JOB i(ACT),‘MODS'//*//OPEN EXEC PGM=ECHO,PARM='SAMPLE CODE'//SYSOUT DD SYSOUT='*'//CALLP EXEC P1,ABC=DEF//DD1 DD DSN=AA.AA,DISP=NEW,DCB=(LRECL=80,RECFM=FB)//DD2 DD *//IKJEFT EXEC PGM=IKJEFT01//SYSTSIN DD DSN=BB.BB,DISP=OLD

Batch jobs suitable for offloading are

identified

Target Environment is set upBased upon customer

Requirements. Access toData is established

Benefits of Offloading Batch Workloads


Reduces costs associated with batch processing up to 40%

Has no impact on applications, processes, or end users

Can be rolled out incrementally or in large scale

Enables off-mainframe batch processes to be run on physical or virtual infrastructure according to customer preference

FIELD EXPANSION, TESTING, & UTILITIES

12 –



Mainframe Field Expansion


Automatically expand fields or critical data elements across the legacy environment

Expand primary key fields such as claim, policy, or account numbers

Expand secondary or index fields such as zip codes, last names, or street names

Expand critical data elements such as address, age, or amount fields

Change data formats (numeric to alpha) of fields or database columns

13 –



Testing Tools & Services


A set of standards and tools to accelerate, improve the quality of, and reduce risk around application testing

Automated solution records technical use cases, pinpoints problems, validates functionality in target environment

Start testing earlier- decoupled mode runs tests at code/application level without database input

Identifies what programs were touched for each path of logic, covers technical use cases from program up to logic

Eliminate chances of human error– know exactly what was and what wasn’t tested

Case Study: Mainframe DataShare


80GB IDMS to Oracle Database Replication Project

Migration was complete in a matter of weeks

Databases automatically synchronized on a schedule

Companies House is Britain’s government bureau with responsibility for recording and storing all information that the country’s 1.8 million limited companies must share with the public.

Case Study: Batch Offloading


Phased Modernization Effort

COBOL refactored to Java

VSAM converted to Oracle Database

Reduced MIPS and reduced mainframe operating costs without any visible or impactful change for users

The MTA is a New York public authority and public benefit corporation that provides transportation services in the NY Metropolitan region through its operating agencies

18 –



Case Study: Mainframe Field Expansion


14 million lines of code analyzed across almost 10,000 programs and shared record definitions

2,000 automated rules generated

Changes to more than 30 database columns affecting more than 54,000 lines of code, in 3,828 programs

Every related reference to each expanded column or field was modified to accommodate new field sizes/types

In business since 1937, Progressive allows consumers to purchase their auto, boat, commercial auto, motorcycle, and RV policies online, over the phone, or via an agent
