In most cases during virtual machine operation, a user can use the tcp
function te enterCP commands directly from the virtual machine. If the
virtual machine has issued a read to theterminal, enter a CP command
with the#CP function. For example: When no longer using virtual tape
drive 397 mapped to real tape drive 492, issue:
#cp detach 397tcp msg cp i am done with real drive 492 VM/370 immediately processes these command lines, and the virtual
machine read remains outstanding.
Note: A user may not always be able to enterCP commands with the tcp function. The read issued by as/vs at the terminal must be for at least
as many bytes as entered in the#CP command line; any additional
informatien is truncated. If the read is for at least three bytes,
enter theiCP command. This command places the user in CP command mode
from whichCP commands can be entered directly. To return to the
virtual machine environment, enter the BEGIN command.
UsingOS/VS In Batch Mode Under VM/370 When many users submit jobs to a single as/vs virtual machine, someone
is generally needed to tend the machine as an operator. The virtual
machineoFerator must make those decisions required of an operator on a
realmachine; that is, deciding what work is going to be done and what
is the most efficient way of doing it.
In batch mcde, one user runs as the as/vs machine (useridOSVS) and
other users (likeCMSI01) may submit jobs either through the virtual
card reader, through thesystem card reader, or through JES remote
stations. If the card reader is not dedicated to theCS/VS virtual machine, place an 10 card at the beginning of each job stream, such as: USERID asvs A
In this card: theUSERIO (or 10) indicates the valid beginning of an ID
card, asvs is the name of theVM/370 user to receive the card input in
his virtual reader, and A is theVM/370 reader class. If the VM/370 system operator has dedicated a card reader to the OS/VS virtual machine, then the 10 card must be omitted at the beginning
of the deck.
A user can send jebs to the as/vs machine from other virtual machines
by spooling his punch to the as/vs userid, such as:tcp speol punch to osvs
Entering this statement causes subsequent punched output to appear in
the virtual card reader for userid asvs.
