Abstract: Given the wide application of mainframe in China’s banking sector, the high cost and complex technology contribute to problems such as high entry barriers and difficulties in grooming mainframe talents in the universities. In order to better educate mainframe system management personnel, a virtual simulation platform for mainframe system management is proposed by Tongji University. ADCD system is deployed based on open source software Hercules to build host virtual machine, and series of system management experiments including security management, storage administration, catalog management and hardware management, among others are designed and implemented on it with interactive web service. The platform can effectively reduce the training cost and operational risk, and shorten the cultivation cycle of mainframe system management personnel.
