Storage & Performance:

New procedures like disk mirroring may minimise physical catalog failure possibilities, but the potential danger of logical mistakes (created by software faults or third party products) still exists. Routine works such as renaming of disk, removing or joining of catalogs take time and are often troublesome, and therefore reside at the bottom of a Storage Manager’s to-do list. With simple installation and integration into catalog concepts and significant performance advantages over all other mainframe catalog management solutions this can easily be managed through Hostsystems’ globally implemented CIM (Catalog Information Manager).

REXX Extensions:

The mainframe programming language REXX is widely used for Rapid Application Development, Decision support, Executive Information Systems, and Automation. REXX is easy to learn and maintain, almost self-documenting and very efficient. Programs built with REXX are simple to maintain when compared with COBOL, PL/1 and assembler. Open Software Technologies’ REXXTOOLS/MVS extends the functionality of the language greatly.
