UP
A name sequence record collection with the following
records. Note that they are distinguished by the ninth character
of the name.
Name: (8,vmname),C'A'
The vmname is authorized for VMCF.
String: (1,flags),(4,extintbuflen),(8,specific_userid)
Key: Segment key to the virtual machine's memory
Name: (8,vmname),C'C'
The key is the CPGCOMM key for this vmname.
While the vmname is "not logged on", this record is absent
or its key is DK(0).
Name: (8,vmname),C'E'
Name: (8,vmname),C'I'
The key is the COMMQ key for this vmname.
Name: (8,vmname1),C'Q',(8,vmname2)
The key is the VMCF sender's key from vmname1 to vmname2
Name: (8,vmname1),C'R',(8,vmname2)
The key is the VMCF receiver's key from vmname2 to vmname1
Name: (8,vmname),C'S',(8,tod)
This record represents a spool file queued for the indicated
virtual machine. The order of the tod's is the order of
the spool files for a given vmname.
This could have been stored locally to each virtual machine
(in the VMCOMM object), but the group record collection
was handy and we weren't concerned about security.
The string has ...
The key is ...
Name: (8,vmname),C'U',(8,tod)
This record represents a pending IUCV connection for
the indicated virtual machine. The tod serves to give each
connection a unique name.
This could have been stored locally to each virtual machine
(in the VMCOMM object), but the group record collection
was handy and we weren't concerned about security.
The string is (8,source_vmname),(2,msglim),(1,flags),(16,userdata)
source_vmname - The name of the VM issuing the connect
request
flags - As follows:
X'20' - This virtual machine may receive priority messages
on this path.
X'40' - Path is initially quiesced
X'80' - Data may be sent in the parameter list
msglim - Maximum number of outstanding messages that
the connecting virtual machine may send on the path
userdata - User data sent by connector
The key is the target's VMGIUCVP key for the path.
Name: (8,vmname),C'V',(8,tod)
This record represents an outstanding IUCV connection
for the indicated virtual machine. The tod serves to give
each connection a unique name.
This could have been stored locally to each virtual machine
(in the VMCOMM object), but the group record collection
was handy and we weren't concerned about security.
The string is (8,source_vmname)
source_vmname - The name of the VM issuing the connect
request
The key is the target's VMGIUCVP key for the path.
