Information
OCLC is a global library cooperative supporting thousands of libraries around the world.
Replatforming of mission-critical online and batch applications as part of strategic imperative to enhance business agility and shutdown the IBM Mainframe.

1000+ users, 225+ screens, 750+ job streams.

Duration: 3 months.
Applications were refactored to Java Application Servers running on Red Hat Linux hosted on VMware instances. COBOL, CICS, BMS & JCL artifacts were recompiled without any changes. RACF was migrated to Open LDAP.
OCLC realized a ROI in 6 months.

“Heirloom’s platform and outstanding project team delivered on the promise of automatically transforming and deploying a complex mainframe workload to 100% Java in 90 days” said Tim Schwab, Director of Enterprise Applications.

A joint project with AWS to deliver a “Mainframe Application in the Cloud” showcase.

Primary objective was to create a cloud-native implementation of an OLTP workload that leveraged the elasticity of AWS.

Duration: 6 weeks.
Heirloom developed a strict implementation of the industry standard transaction processing benchmark, based on the TPC-C specification.

This COBOL/CICS application was run on an IBM Mainframe and then refactored (without any code changes) to AWS with Heirloom, and deployed as a Java application to Apache Tomcat (in a scalable AWS Beanstalk environment).
Monolithic OLTP application was successfully deployed as a cloud-native (dynamically scalable, highly-available, integrated) Java application on AWS.

Transaction throughput measured at 1,108 transactions per second, equivalent to 15,200 MIPS.

Annual infrastructure cost was 45X cheaper than equivalent IBM Mainframe system.

Offloading of Pacbase development from the mainframe to PC workstations.

Duration: 4 weeks.
The Heirloom SDK was configured to work in IBM compatibility-mode (including use of the EBCDIC code page). This provided an agile modern Eclipse IDE for compiling and validating Pacbase applications.
Significant reduction in Mainframe MIPS usage through offloading of application development processing to PC workstations.
