The VTAM topology agent terminates
an ongoing snaLocalTopo snapshot action under
the following conditions: - A stop snapshot action
request is received.
- An error occurs during snapshot processing
in VTAM®.
- The association between the local CMIP services and the manager
application program's CMIP services terminates.
The following is an example of a valid stop request: msg CMIP-1.ROIVapdu (invokeID 196613,
operation-value 7, argument (baseManagedObjectCla
ss 1.3.18.0.0.2152, baseManagedObjectInstance (di
stinguishedName (RelativeDistinguishedName (Attri
buteValueAssertion (attributeType 1.3.18.0.2.4.6,
attributeValue "NETA")), RelativeDistinguishedNa
me (AttributeValueAssertion (attributeType 1.3.18
.0.0.2032, attributeValue "SSCP1A")), RelativeDis
tinguishedName (AttributeValueAssertion (attribut
eType 1.3.18.0.0.2216, attributeValue (string "Sn
aLocalTopology"))))), actionInfo (actionType 1.3.
18.0.0.2222, actionInfoArg (stop 196612))))
The stop request in the previous example looks very similar
to the associated start request except for the actionInfoArg portion
of the request. For the stop request, the stop keyword
is used along with the invoke identifier of the start request that
is to be terminated.
The result of the VTAM topology agent's processing
of a stop request is three messages: - An empty set linked-reply for the start request
- An RORS response to the start request
- An RORS response to the stop request
The following shows examples of these three messages:
First, the empty set linked-reply: (Note that the
associated invoke identifier in a linked-reply is given in the linked-ID field.)
msg CMIP-1.ROIVapdu (invokeID
1, linked-ID 196612, operation-value 2, argument
(actionResult (managedObjectClass 1.3.18.0.0.215
2, managedObjectInstance (distinguishedName (Rela
tiveDistinguishedName (AttributeValueAssertion (a
ttributeType 1.3.18.0.2.4.6, attributeValue "NETA
")), RelativeDistinguishedName (AttributeValueAss
ertion (attributeType 1.3.18.0.0.2032, attributeV
alue "SSCP1A")), RelativeDistinguishedName (Attri
buteValueAssertion (attributeType 1.3.18.0.0.2216
, attributeValue (string "SnaLocalTopology"))))),
actionReply (actionType 1.3.18.0.0.2222, actionR
eplyInfo ()))))
Next, the RORS for the start request: msg CMIP-1.RORSapdu (invokeID
196612)
Finally, the RORS for the stop request: msg CMIP-1.RORSapdu (invokeID
196613, resultOption (operation-value 7, result
(managedObjectClass 1.3.18.0.0.2152, managedObjec
tInstance (distinguishedName (RelativeDistinguish
edName (AttributeValueAssertion (attributeType 1.
3.18.0.2.4.6, attributeValue "NETA")), RelativeDi
stinguishedName (AttributeValueAssertion (attribu
teType 1.3.18.0.0.2032, attributeValue "SSCP1A"))
, RelativeDistinguishedName (AttributeValueAssert
ion (attributeType 1.3.18.0.0.2216, attributeValu
e (string "SnaLocalTopology"))))), actionReply (a
ctionType 1.3.18.0.0.2222, actionReplyInfo ()))))
