Our Expertise With The Cortex Migration System (Cortex-MS)


The Cortex-MS Software

The Cortex Migration SystemTM (Cortex-MSTM) was almost completely developed in France by Sisro from 1974 to 1984. In 1984, Sisro entered into a world-wide licensing agreement with IBM which distributed Cortex-MS to its VSE customers from 1986 to 1997 under the name MVS Migration System (MVS-MS). The Allen Systems Group (ASG) bought Sisro in 2000 and currently owns the Cortex-MS product.

The important milestones in the life of the Cortex-MS product are:

Since 1987, Cortex-MS has been functionally stabilised, i.e. it received no significant functional enhancement. During the 1990s, Cortex-MS received a few technical enhancements, such as allowing exit routines to be written in VS COBOL II or COBOL/370 (these changes were mandated by IBM's drop of support for the VS COBOL for OS/VS compiler). In 1993, the back-end portion of the product which converts the PCL language to MVS JCL was replaced with version 5 of Sisro's Cortex-PDB stand-alone product. Although these changes made it somewhat easier to write Cortex-PDB customisation exit routines, they did not allow other components of Cortex-MS to handle additional programming languages, utility programs or features of the VSE JCL.

Cortex-MS is still marketed by ASG, although it doesn't support many of the JCL features, utility programs or languages commonly used by most VSE/ESA or z/VSE installations today. In particular, Cortex-MS does not support the following: Conditional JCL, VS COBOL II and COBOL for VSE, VSAM-managed SAM, CA-Dynam and Epic utilities, IDCAMS BACKUP/RESTORE, SYNCSORT/DFSORT/CA-SORT extensions, FTP, SQL/DS (DB2), CA-Datacom, Adabas, back-up/restore utilities, and many other VSE components (full list available on request). A VSE installation that licenses Cortex-MS must dedicate a large amount of resources to develop the custom code required to obtain a reasonable level of automation when converting its VSE applications to z/OS.
