Legacy systems are older systems such as mainframes and mini-computers that were widely used before the proliferation of PCs and the internet in the 1990s. At this time, Digital’s VAX and Alpha systems running VMS and OpenVMS were the most widely adopted in many countries, including the UK.
However, the commercial success of PCs ultimately led to Digital being bought by Compaq and the end of Alpha production. In 2002, Compaq was acquired by HP.
Since 2002, development of OpenVMS has slowed and subsequent OpenVMS releases have focused on supporting Itanium and HP systems.
Many OpenVMS customers had to decide which option was best for them
- Migrate to modern PC-class servers running Linux or Windows or
- Use OpenVMS emulation or virtualization software
But many customers kept running OpenVMS on the original hardware, despite diminishing levels of available support. Fearing a complete end-of-life for OpenVMS, these customers have welcomed the announcement that OpenVMS development will restart.
In July 2014, VMS Software Inc. was formed to continue development of OpenVMS, with promised support for x86 architecture.
Extensive Support for Legacy Systems
While many RapidGen customers run OpenVMS systems, almost all need to integrate their data and applications across several programming languages, file formats, and systems. However, modern IT departments are finding this increasingly difficult due to lack of skills, vendor support, documentation, and replacement hardware.
Whether IT departments need systems management, data integration, or migration and modernization they require expertise in proprietary data sources and legacy systems.
RapidGen has extensive expertise and support for a wide range of legacy systems* including
- 3GL Programming Languages including FORTRAN, COBOL, BASIC, Pascal and C
- Itanium – IA-64 Itanium including OpenVMS I64
- OpenVMS including Alpha AXP and VAX/VMS
- RS/6000 including IBM AIX and PowerPC
- Sun Sparc including SunOS, Solaris and OpenSolaris
- Tru64 Unix previously known as Digital Unix and OSF/1
