【Fujitsu】 OSIV/X8 FSP

 OSIV/X8 FSP was an operating system (hereinafter “OS”) developed by significantly enhancing OSIV/X8 for Fujitsu’s FACOM M series medium-scale general-purpose computers, and was announced in February 1983.
 As the use of information systems had rapidly expanding and the technology had been becoming more sophisticated, the demand below had been becoming stronger. The demand was to provide an architecture to meet end user-oriented systems such as OA (office automation) and FA (factory automation), which were required ease of use with focusing on operability, and to meet diversified communication forms caused by the open communication lines. In order to address this demand, Fujitsu developed OSIV/X8 FSP, which was based on OSIV/X8.

 The following describes the features of OSIV/X8 FSP and functional enhancements of OSIV/X8 FSP:

1. Features of OSIV/X8 FSP

 OSIV/X8 FSP had the following features:

(1) Establishment of an easy-to-use information system
 For OSIV/X8 FSP, Fujitsu provided support tools that enabled the end users to easily develop programs in order to meet the ever-growing demand for application program development.
- Supported JEFII, which integrated the previously provided JEF with multimedia processing functions such as image and document processing.
- Provided the relational database AIM/RDB, which was easily installed and operated, and provided the function to use AIM/RDB through the interactive integration tool INTERACT.
(2) Easy operation
 With OISIV/X8 FSP, in order to achieve automation and labor-saving in system operation, the company formed a new storage hierarchy by adding the cartridge library device FACOM 6460 and consequently further enhanced the previous AOF (Advanced Operation Facility).
(3) Support for new networks
 At that time, LANs were beginning to attract attention as the basis networks for office system building in response to the significant deregulation of limit of line use by the 2nd stage of opening communication lines. OSIV/X8 FSP therefore supported new local networks and global networks.
- Enabled the establishment of an integrated local area network through high-speed transmission of various media using an optical data highway, and through switching of telephone, facsimile and data terminals using a digital switching system.
- Enabled the establishment of intra-enterprise and inter-enterprise networks through further facilitated inter-host communication by enhancing the basic communication functions (NCP-G and VTAM-G MSNF) and the business communication processing function (AIM/DTPF).
(4) Faster development and increased maintenance efficiency
 For OSIV/F4 FSP, Fujitsu enhanced its software products in order to shorten software development time and increase maintenance efficiency.
2. Functional enhancements of OSIV/X8 FSP

 After OSIV/X8 was announced in February 1983, Fujitsu introduced functional enhancements of the OS and provided new software. The following table shows the major functional enhancements.
