Powerful processing capacity , security , reliability, high performance advantage of the large computer , it handle complex super ability to multi-task , downtime is much lower than other types of server ; the large computer I / O capability , specializes in mega - database access; it uses dynamic partition management , according to the size of the different applications load the flexibility to allocate system resources ; prevent intrusion from the ground up to make large-scale computer security improved . Above characteristics in financial services , telecommunications , transportation , energy , government and other industries , the mainframe is irreplaceable . Based on the expensive mainframe prices and huge system configuration , so rarely been applied to the company's financial system module , but decided to use IBM's own products (Z Series host for IBM's security considerations and the use of performance and OS/390 system ) . Financial , accounting , and data import and export statements , are unusually large for the IBM Corporation , and the mainframe but just provide what we need . RAS ( Reliability, Availability, Serviceability high-reliability , high-availability , high- service ) , I / O processing capabilities as well as the best choice for ISA it is to deal with the huge data . The complete IBM mainframe (0S390) upgrade work on the the MVS environment of financial system . First analysis of the characteristics of the SLCM ( Software Configuration and Library Manager ) - based locales OS PL / 1 and JCL (Job Control Language) , PL / 1 development and compiler , then the SCLM environment then write job control language ( JCL) to test the application of PL / 1 development program . Finally , through the upgrade of the financial system , removing redundant code , optimize the structure of the program , greatly improving the efficiency of the system .
