JCL to Shell and Batch Script Translation for Mainframe Modernization

Key Considerations for JCL Translation

• Language transition: Convert JCL statements into Unix shell scripts or Microsoft Windows batch files.
• Mainframe feature support: Preserve key operations such as program launches (EXEC PGM), file processing (SORT / COPY), data export (IDCAMS), and GDG versioning.

SoftwareMining JCL Function Coverage

• EXEC PGM
  Runs translated Java and C# programs from the command line.
  
  
• EXEC PROC
  Converts cataloged procedures into separate shell scripts, which run in a standard way.
  
  
• Sort / DFSort (implemented in Java and .NET)
  SoftwareMining's Sort / DFSORT utility delivers about 90 percent of the functions provided by DFSORT or SyncSort. For the full feature list, see SoftwareMining Sort Documentation.
  Note: IF/THEN and JOIN-KEYS functionality are distributed under a separate license.
  
  
• Copy (implemented in Java and .NET)
  The COPY utility uses SoftwareMining's Sort / DFSORT implementation.
  
  
• IDCAMS / REPO
  Used to export data from SQL (replacement for VSAM KSDS). For details see SoftwareMining ExportDb Documentation.
  
  
• IEBGENER (implemented in Java and .NET)
  Used for copying and printing sequential files.
  
  
• IEFBR14 (implemented in Java and .NET)
  Used for renaming and deleting sequential files.
  
  
• IKJEFT01
  Typical uses include:
  • Launching translated programs
  • Copying, renaming, or deleting VSAM data files (mapped to operating system utilities)
  • Calling mainframe routines such as DSNTEP2 or DSNTEP4 to run SQL statements on the database. These become calls into SoftwareMining's SQLLoader.
  
  
  
• DFSRRC00 (Java and .NET implementations)
  Launches IMS programs in either TM (online) or DLI (batch) mode. Binds the specified PSB and passes user parameters to the module.
  
  
• GDG (implemented in Java and .NET)
  GDG versioning for flat files. For details see SoftwareMining GDG Documentation.
  
  
• ICETOOL (implemented in Java and .NET) (distributed under a separate license)
  Common ICETOOL features such as COPY, SELECT, and SPLICE are supported. Additional functions are available on request.
