Advantages Of MAINFRAME:-


2)Reliability and Availability

3)High level Computing

4)Problem Solving

5)Long lasting performance

Applications of Mainframe:

Mainframe computers are  primarily used by large organizations for critical applications 

such as bulk data processing used in banking sector,Insurance,Financial Services,Airway Reservations,Payroll Process,Telecom sector etc.

IBM Mainframe and Associated Technologies:-

1)CICS stands for Customer Information Control System. CICS was developed in 1968 by IBM. CICS allows users to develop and execute online application in an MVS environment. CICS has become the most commonly used server for Internet applications. CICS is a transaction processing system which is also called as Online Transaction Processing (OLTP) Software. 

CICS is a data communication system that can support a network containing hundreds of terminals.

2)COBOL stands for Common Business Oriented Language.The US Department of Defense, in a conference, formed CODASYL (Conference on Data Systems Language) to develop a language for business data processing needs which is now known as COBOL.

COBOL is used for writing application programs and we cannot use it to write system software. The applications like those in defense domain, insurance domain, etc. 

which require huge data processing make extensive use of COBOL.

3)DB2 provides you the basic understanding of concepts of database, database installation and management. 

4)IMS stands for Information Management System. IMS was developed by IBM with Rockwell and Caterpillar in year 1966 for the Apollo program to send a man to the moon. It started the database management system revolution and still continues to evolve to meet data processing requirements. IMS provides an easy-to-use, reliable, and standard environment for executing high-performance transactions. 

IMS database is used by high-level programming languages like COBOL to store data in hierarchical arrangement and access it.

5)Job Control Language (JCL) is the command language of Multiple Virtual Storage (MVS), which is the commonly used Operating System in the IBM Mainframe computers. JCL identifies the program to be executed, the inputs that are required and location of the input/output and informs the Operating System through Job control Statements. In mainframe environment, programs can be executed in batch 

and online modes. JCL is used for submitting a program for execution in batch mode.

6)VSAM stands for Virtual Storage Access Method. VSAM is a file storage access method used in MVS, ZOS and OS/390 operating systems. It was introduced by IBM in 1970’s. It is a high performance access method used to organize data in form of files in Mainframes. VSAM is used by COBOL and CICS in Mainframes to store and retrieve data. 

VSAM makes it easier for application programs to execute an input-output operation.
