DFHSM

Data Facility Hierarchical Storage Manager:

1)Program that automatically performs space management and availability management in a storage device hierarchy.
2) DFHSM makes sure space is available on DASD volumes so that we can extend our old data sets and allocate new ones.
3) DFHSM also makes sure that backup copies of our data sets are always available if our working copies get lost or corrupted.

SPACE MANAGEMENT

PRIMARY SPACE MANAGEMENT
SECONDARY SPACE MANAGEMENT

PRIMARY SPACE MANAGEMENT

Deletion of temporary data sets
Deletion of expired data sets
Release of unused, over allocated space
Migration to DFHSM-owned migration volumes

SECONDARY SPACE MANAGEMENT

Migration level cleanup, which includes deletion of expired migrated data sets and some migration control data set (MCDS) records
Migration level 1 (ML1) to migration level 2 (ML2) volumes.

What is console?

1) Computer operators are responsible for monitoring

and managing the operations of MVS operating system.

2) Computer operators use consoles to

· Issue system commands

· Receive system messages

OperatorèConsoleèMVS

MVS sends messages via the console that

· Inform you of the status of jobs

· Request that you perform a required action, such as mounting tapes or Cartridges 

Operator çConsoleçMVS 

Consoles provide a communication link between you

and MVS, JES2/JES3, VTAM, other system components and

application programs.

So console is nothing but the interface between Operating system (MVS) and the User.
