VSAM Online Test

VSAM is introduced by IBM and stands for Virtual Storage Access Method. It is a file storage access method that is used in MVC, ZOS, and OS/390 operating systems. VSAM is a high-performance access method that is used to organize data in Mainframes. It helps organize records into four types of data sets: key-sequenced, entry-sequenced, linear, or relative. VSAM is used by COBOL and CICS in Mainframes to store and retrieve data. Input-Output operations in an application program are made easy by using VSAM.

VSAM online test helps recruiters and hiring managers assess candidates' skills related to managing virtual storage access methods. The VSAM technical test is designed by experienced subject matter experts (SMEs) to evaluate and hire Mainframe developers per industry standards.

VSAM online test helps to screen the candidates who possess traits as follows:

  • Strong knowledge of types of VSAM datasets
  • Ability to work with file disposition, file attributes, and access methods
