Chapter 6. The Installation Verification
Procedure
Introduction
The InstallationVerification Procedure (IVP) for VM/370 is designed to exercise
the generatedsystem to verify that basic V!/370 facilities are operable. The IVP is
contained in two files using theEXEC facility of CMS, and uses two virtual machines in addition to the system operator's virtual machine. The tests exercise the following areas
ofCP: • Multiple virtual aachine support • I/O spooling • Transferring of spooled data to other
virtualmachines • Offline I/O operations • Sending of messages to the system
operator• Paging operations • Task dispatching and scheduling • Disk I/O support • Autoaatic warm start following abnormal teriiination 1711 n ""'.&. wu, J. V The following facilities of CMS are
exercised:• lormal CMS command processing • Disk formatting • Copying of files • Creation and aodificaticn of files via
EDITcommand • Assembly of executable programs • Execution of user programs • Creation and execution of user-written co.mands • printing and punching of CMS files • Issuing of commands to CP • Use of multilevel nested EIEC procedures • Stacking and unstacking of command and
data inputfrom the terminal • Comaunication procedures with user froll EXEC Several other system facilities,
incidental to theprimary IVP tests, are
exercised. Certainsystem facilities, such
as preferred execution options,
virtual=real,OS ISIM, and VSAM and Access Method Services under CMS, are not
exercisedby the IVP. The IVP requires operator intervention only when an operational decision is to be
.ade, or to initiate theIVP tests themselves.· All file creation, erasure, management, and logoff of the virtual
machines (with the exception of the system
operator) at testcompletion is performed automatically without operator or user
action.
