  1. OS/390 NEW FACILITIES

  2. The challenges in today's business environment are unpreecedented. The computerization and globalization of the marketplace have completely changed the ways we design, produce, market, and use products. OS/390 represented a new concept in large-system, large-enterprise operating system software. The keywords were integration, functionality, and investment protection.

  3. OS/390 allows you to: • - Conduct secure business over the Internet, also called e-business • Model and implement business processes across systems and networks as business objects and use them transactionally, locally or remotely • - Use Java, a language that can be used to build both Internet and • general business applications. • - Consolidate separate servers onto OS/390, allowing you take take advantage of the synergistic value of integrated server processing and resultant reduced systems management costs • - Mine data intelligently, giving you the chance to transform your huge stores of raw data into meaningful information that can translate into new market opportunities • - Span both large and smaller enterprises with OS/390 technology

  4. OS/390 provide wide range of facilities include: • # Network : • WebSphere Application Server for OS/390 (previously delivered as Domino Go Webserver 5.0) enables the use of S/390 as a Web server. • BookManager BookServer for the World Wide Web enables customers to provide entire libraries of documents via the World Wide Web. • LANRES lets: • = Host users administer multiple NetWare servers • = Host users and NetWare workstation users print documents or data on printers located anywhere in your site • = Host users manage NetWare files and directories NetWare workstation users store data on host direct access storage devices (DASD)

  5. LAN Server for OS/390 enables LAN workstation users to store and share data and applications in a central location on a System/390 which allows the large storage capacity of a System/390 to relieve the capacity constraints of workstation-based servers. • OSA/SF is a base, non-exclusive element that supports S/390 Open System Adapter (OSA-Express and OSA-2) hardware features which to Ethernet, Fast Ethernet (FENET), and Asynchronous Transfer Mode (ATM) networks. OSA-Express connects to Gigabit Ethernet, while OSA-2 supports Fiber Distributed Data Interface (FDDI) and token-ring connection to deliver connectivity via directly-attached local area clients using: • =Transmission Control Protocol/Internet Protocol (IP) network protocol • =Systems Network Architecture Application Peer-to-Peer Networking • (SNA/APPN) and SNA subarea networking protocol • =Internet Packet Exchange (IPX)

  6. - NFS acts as a file server to workstations, personal computers, or other authorized systems in a IP network. It also provides an OS/390 client. It enables client users to remotely access OS/390 data sets or OS/390 UNIX Services files from any system on a IP network that uses client software for the SUN Network File System protocol. The remote data sets or files are mounted from the mainframe to appear as local directories and files on the client system. - Secure Sockets Layer (SSL) is a communications protocol that provides secure communications over an open communications network (for example,the Internet). The SSL protocol is a layered protocol that is intended to be used on top of a reliable transport, such as Transmission Control Protocol (TCP/IP).

  7. - CICS Web Interface allows web browsers to call programs in a CICS system using the hypertext transfer protocol (HTTP). The web browser constructs an HTTP request, which is passed across the network to TCP/IP for MVS in the server. TCP/IP for OS/390 relays the request to the CICS Web Interface, which calls a CICS program to service the request. The output from the CICS program is sent back to the web browser in an HTTP response.

  8. # Security server : • RACF that means you get : • = Flexible control of access to protected resources • = Protection of installation-defined resources • = Ability to store information for other products • = Choice of centralized or decentralized control of security profiles • = An ISPF panel interface • = Transparency to end users • = Exits for installation-written security routines • OS/390 Firewall Technologies is a network security "firewall“ program for OS/390. In essence, the OS/390 "firewall" consists of traditional firewall functions as well as support for Virtual Private Networks.

  9. DCE Security Server for OS/390, part of the OS/390 optional Security Server feature along with RACF, provides a fully functional security server for OS/390. • LDAP server allows LDAP directory storage from an OS/390 system and will also serve as a back-end to RACF.

  10. # Application Enablement : • DFSORT provides you with the ability to do faster and easier sorting, merging, copying, reporting and analysis of your business information, as well as versatile data handling at the record, field and bit level. • Language Environment provides common services and language-specific routines in a single run-time environment.with the following IBM compiler products: • = OS/390 C/C++ • = COBOL for MVS and VM • = C/C++ for MVS/ESA • = COBOL for OS/390 and VM • = AD/Cycle C/370 • = PL/I for MVS and VM

  11. = SAA AD/Cycle PL/I MVS and VM • = IBM VisualAge for Java, Enterprise Edition for OS/390 • = VS FORTRAN and FORTRAN IV (in compatibility mode) • SOMobjects runtime library is a set of functions for creating objects and invoking methods on them. • Visuallift (Runtime Environment and Application Development Environment) is a tool to modernize the interface of existing host applications. The new user interface is located on the workstation - either OS/2 or Windows. • C/C++ IBM Open Class Library is a comprehensive set of C/C++ class libraries that is used to develop applications. • Text Search Engine is an advanced search engine. The most important components are client/server handling, linguistic support for different languages, and queue mechanisms. Free-text searching, Boolean logic, and fuzzy searches are supported. The search results can be ranked by relevance.

  12. - S/390 hardware implementation of IEEE floating-point arithmetic now supports the common IEEE industry standard (ANSI/IEEE Standard 754-1985) with 16 floating point registers, compared to 4 registers. • # Distributed Computing Services • The DCE Services provides the strengths of a distributed computing environment: • = Transparency of data and logic • = Distributed, consistent directory service • = Security for both clients and servers integrated in execution path • = Scalability of distributed applications • = In teroperability and portability.

  13. The DCE user-data privacy features enable data encryption using the data encryption standard (DES) algorithm and the commercial data masking facility (CDMF) algorithm. One feature supports the DES and CDMF algorithms and; the other feature supports the CDMF algorithm. • Infoprint Server It lets you consolidate your print workload from many servers onto a central OS/390 print server.Infoprint Server delivers improved efficiency and lower overall printing with the flexibility for high-volume, high-speed printing from anywhere in the network. With Infoprint Server, you can reduce the overall cost of printing while improving manageability, data retrievability, and usability.

  14. - The Distributed File Service (DFS) provides support which is the Distributing Computing Environment (DCE) distributed file service component. - MQSeries products enable applications to use message queuing to participate in message-drivenprocessing. With message-driven processing, applications can communicate with each other on the same or different platforms, by using the appropriate message queuing software products. For example, MVS/ESA and OS/400 applications can communicate through MQSeries for MVS/ESA and MQSeries for AS/400 respectively. With MQSeries products, all applications use the same kind of messages; communications protocols are hidden from the applications.

  15. # SecureWay Communications Server : - IP (formerly known as IBM TCP/IP) is a set of industry standard protocols and applications that allow you to share data and computing resources with other computers, both IBM and non-IBM. Some common uses of IP include: = Electronic Mail = File Transfer = Remote Logon = Internet - IP CICS Sockets (integrated into the base TCP/IP stack) provides the ability to use the generalized Application Programming Interface (API) and socket applications in COBOL, PL/I, and assembler.

  16. - IMS IP support (integrated into the base TCP/IP stack) allows the development of peer-to-peer applications in which IMS and a IP-connected peer form a client/server relationship. Using this support, IMS can be either client or server. - AnyNet implements the multiprotocol transport networking (MPTN) architecture. AnyNet enables application program types to communicate without change over different transport networks (SNA,IP,…) and across interconnected networks.
