Chapter 17: Migrating from MVS Workbench

MVS Workbench is a front-end to Workbench (and its add-ons), intended to make Workbench seem more familiar to mainframe users by giving it a mainframe-style user interface. This chapter describes facilities in Mainframe Express to help you migrate applications created using Workbench + MVS Workbench.

17.1 Overview

For an introduction to the Mainframe Express interface, see the chapter Using Mainframe Express. It is a graphical interface, resembling Animator V2 in Workbench. However, Mainframe Express includes catalog support based on that in MVS Workbench.

Since applications created using Workbench + MVS Workbench are Workbench applications, all the advice on migration given in the COBOL Workbench part of this book applies. In addition, your data files will be in catalogs supported by MVS Workbench, and so they must be migrated to Mainframe Express catalogs. Mainframe Express includes facilities to help you do this.

17.2 Converting Catalog Entries

A migration tool is supplied that reads an MVS Workbench catalog file and adds entries to the Mainframe Express catalog. These entries point to the files in the MVS Workbench catalog directory tree. The Mainframe Express catalog is created if it doesn't exist. The existing files are not moved or relocated and the MVS Workbench catalog is not changed in any way.

The migration tool is not on the Mainframe Express menus. Run it from the Mainframe Express Command Prompt, and follow its prompts. Its command line is:

mvswbcnv /mvswbcat:pcdsn1 /mvsxcat:pcdsn2

where the parameters are:

pcdsn1 Path and filename of the MVS Workbench catalog. Specify the ispcatlg.dat file that is pointed to by the SYSCATLG environment variable.
pcdsn2 Path and filename of the Mainframe Express catalog.
