Mainframe Modernization Technology

Mainframe Modernization Technology List

This is a list technologies used for mainframe modernization and replatforming. This list is updated as new information comes in. Feel free to send updates using the contact us and we will update the page promptly.

This information is to assist companies in their research to find the vendors and technologies that best suite their needs; The information should not be relied on as it is accumulated from a variety of sources and self reporting by vendors.

Technology

• COBOL

  Micro Focus Request Update

  The industry defacto standard as the longest established open systems compiler. Has very good IBM COBOL compatibility when the correct set of compile options are specified. Licensing scheme can vary from case by case so make sure you have licensing costs secured and also make sure licensing will not change after you are in production.

  This compiler generates highly optimized .o or .so files.

  OpenCOBOL Request Update

  Renamed to GnuCOBOL

  GnuCOBOL Request Update

  Open Source COBOL that is actively developed with an active community. Renamed from OpenCOBOL after it became part of the Gnu Community. Compiles several dialects of COBOL and the community welcomes bug reports related to IBM COBOL compatibility.

  This COBOL compiler generates C code that is compiled by gcc.

  gCOBOL Request Update

  Open Source COBOL compiler that is only recently inspired. Being developed by small group. This compiler is not yet available but is targeting IBM COBOL compiler compatibility. It will be a first class member of the gnu compiler suite (gcc, gfortran, ggolang, …)

  This compiler generates .o or .so files directly (no intermediate language)

  COBOL-IT Request Update

  COBOL-IT is technically an open source compiler because it is a fork of OpenCOBOL but it was commercialized by adding nonopensource components. The commercial implementation was purchased by Micro Focus.

  This COBOL compiler generates C code that is compiled by gcc.

  Recently the original team that forked COBOLIT from OpenCOBOL has created a new company to fork the code from Micro Focus. The new company is called Cloud COBOL.

  Liber COBOL Request Update

  P3 COBOL Request Update

  This COBOL compiler generates Java code that is compiled by a Java Compiler to Class files. It provides extensions to embed Java directly into COBOL code and to Code COBOL in a Java-Like format named "Java Augmented Syntax". Execution is then in the Java environment of choice.

  This compiler outputs Java which is subsequently compiled to .class files.

  Heirloom COBOL Request Update

  Heirloom COBOL is part of their Heirloom Suite for migrating applications from mainframe to JVM. This COBOL compiler was created specifically for migrating mainframe applications to the JVM.

  Heirloom COBOL produces Java which is subsequently compiled to .class files.

  AcuCOBOL Request Update

  AcuCOBOL is an interpreted COBOL. It was purchased by Micro Focus. It is mostly used by people that are moving an application from one UNIX Platform to another, for instance, Sun to Linux.

  This COBOL compiler generates its own interpreted code that is run by its own runtime.

  Fujitsu COBOL Request Update

  This COBOL Compiler is mainly focussed on .NET as a target platform, with different versions for Windows and LINUX.

  IBM COBOL Request Update

  IBM COBOL is newly released for Linux and produces compiler messages very similar to Mainframe COBOL.

  One point of possible confusion is that for many years IBM resold the Micro Focus compiler. Some people incorrectly called that the IBM compiler. The IBM COBOL compiler does not share any code with the Micro Focus compiler and is completely distinct.

  This compiler produces .o and .so files directly.

  NTT Enterprise COBOL Request Update

  Generates Java class files. Typically used with UniKix and the NTT replatforming tool set.

• CICS

  NTT TPE formerly UniKix Request Update

  Liber Z Request Update

  OpenKicks Request Update

  Sold as source to companies that want to control their entire technical stack.

  Heirloom Request Update

  IBM TX Series Request Update

  Enterprise Server (Micro Focus) Request Update

  TMAX Request Update

• Assembler

  NJEMA Request Update

  Converts 370 or 390 Assembler to plain COBOL Code. Subsequent refactoring to well structured COBOL code is possible.

  Liber Iris Request Update

  Converts Assembler to COBOL

• PL1

  Liber*Iris Request Update

  Converts PL1 to COBOL

  Heirloom Request Update

• JCL

  UV Software Request Update

  NTT BPE Request Update

  Batch Processing Engine

• Liber*Z

• DFSORT

  Syncsort Request Update

• IMS

• Scheduler
