Maps logical filenames used in code to physical VSAM datasets or DB2 databases.
Virtual storage is divided into 4KB blocks called pages. The operating system moves pages between central storage (RAM) and auxiliary storage (Direct Access Storage Devices or DASD) via paging. When an entire address space becomes inactive, z/OS performs swapping, moving the active pages of the address space out of central storage to optimize system efficiency. Task and Job Management
Syntax rules that trip up most developers during interviews.
JCL is the command language used to define and control jobs in an IBM mainframe operating system. The refresher covers:
SEARCH : Executes a sequential linear scan through a table. The table does not need to be sorted. It requires manual index initialization via SET INDEX TO 1 .
