Mantissa Corporation: 32bit Intel on IBM mainframe
Q. What level of hardware is required for x86VM? A. An IBM System zEnterprise class server. At minimum a z114 or z196 or higher level. Q. What operating systems can I run on z86VM? A. At this point, only Linux has been successfully tested. We’re working to enable additional systems. Q. When will Windows be certified? A. That’s a two step process. First we have to complete our own testing. Then we need to submit our test results to Microsoft for review. We hope that will be quick. When that Beta is ready, customer experience will help. Q. When will 64 bit support be completed? A. We believe there is sufficient function and performance in our 32 bit capabilities. We’ll see how well that is accepted before we make any commitment to 64 bit.

Another good choice is the open-source program lftp. It supports TLS/SSL and it deals well with MVS data sets. The only problem was that it cannot change the current working directory because lftp doesn’t understand that a path like ‘SYS1’ is absolute. It is temping to replace old FTP-based transfers by SFTP. Unfortunately SFTP and SCP of OpenSSH are restricted to Unix files on HFS and ZFS. It is not possible to access MVS data sets through SFTP or SCP. The good news are: Some Unix commands like cat, mv and cp of USS are extended to access MVS data sets. Also the TSO commands OPUT, OGET and OCOPY allow the file exchange between MVS and USS. Out of the box a two-phase transfer is technically feasible. To transfer a file for processing onto z/OS the following two phases apply. The first phase transfers the files via SFTP into a HFS/ZFS file. The second phase copies the Unix file into a MVS data set by the commands mentioned before. Batch processing can run unmodified upon this MVS d
TmaxSoft provides a full range of advanced enterprise system software to industry leaders throughout the world. TmaxSoft’s legacy modernization software products provide IT integrity, reliability, expandability and cost reduction to over 1,400 leading organizations throughout the world, including clients within the US, Korea, Japan and China.
TmaxSoft specializes in legacy system modernization and provides two comprehensive paths for enterprises: mainframe rehosting and implementing SOA-based total enterprise systems. Our powerful OpenFrame rehosting software has been used worldwide to migrate mission-critical IT systems from mainframe-based environments to more flexible and cost-efficient open system environments. In April of 2006, TmaxSoft completed rehosting the system of Samsung Life Insurance, a major life insurance provider. At the time, this was the largest rehosting project ever undertaken (7,500 MIPS). Our ProFrame application framework and associated products have been
Dell guns for IBM mainframes with Clerity gobble
Clerity says it has over 1,300 sites worldwide using its migration and rehosting tools today. At the time Sun bought the UniKix business from Critical Path more than a decade ago, that business had 300 customers with 900 installations and Sun was expecting to do around 50 mainframe replacements a year and generate maybe $100m in hardware, software, and services revenues a year. Sun boosted the UniKix installed base to 1,400 sites by the time it sold it to Clerity in 2006.
Clerity to Revive Mainframe Rehosting after Acquiring Sun Tools
Clerity Solutions has a 15-year history of providing porting services and tools from obscure computing systems to more modern computers. But by acquiring a set of mainframe application porting and rehosting tools from Sun Microsystems, which the company quietly did at the end of June, Clerity is now a relatively big player at many mainframe shops.
Clerity, which is based in the Chicago suburb of Oakbrook Terrace, has been doing ports of old Wang word processing systems and HP 3000 MPE-based minicomputers to other platforms, and had approximately 25 employees before buying Sun’s Mainframe Transaction Processing (MTP) and Mainframe Batch Manager (MBM) systems software and middleware for an undisclosed sum. The MTP software is, in essence, a clone of IBM’s CICS transaction monitor and COBOL environment for mainframes, and MBM is a set of software that can mimic the Job Control Language of a mainframe that runs batch jobs. Clerity has acquired all of the intellectual property associated
