Action termination

The VTAM® topology agent terminates an ongoing snaNetwork 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 snapshot action request :

             msg CMIP-1.ROIVapdu (invokeID 196612,
  operation-value 7, argument (baseManagedObjectCl
 ass 1.3.18.0.0.2151, baseManagedObjectInstance (d
 istinguishedName (RelativeDistinguishedName (Attr
 ibuteValueAssertion (attributeType 1.3.18.0.2.4.6
 , attributeValue "NETA")), RelativeDistinguishedN
 ame (AttributeValueAssertion (attributeType 1.3.1
 8.0.0.2032, attributeValue "SSCP1A")), RelativeDi
 stinguishedName (AttributeValueAssertion (attribu
 teType 1.3.18.0.0.2216, attributeValue (string "S
 naNetwork"))))), actionInfo (actionType 1.3.18.0.
 0.2222, actionInfoArg (stop 196610))))

The stop request in the previous example looks much like 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 196610, operation-value 2, argument
  (actionResult (managedObjectClass 1.3.18.0.0.215
 1, 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 "SnaNetwork"))))), actio
 nReply (actionType 1.3.18.0.0.2222, actionReplyIn
 fo ()))))

Next, the RORS for the start request :

                     msg CMIP-1.RORSapdu (invokeID
  196610)

Finally, the RORS for the stop request:

                     msg CMIP-1.RORSapdu (invokeID
  196612, resultOption (operation-value 7, result
 (managedObjectClass 1.3.18.0.0.2151, managedObjec
 tInstance (distinguishedName (RelativeDistinguish

 stinguishedName (AttributeValueAssertion (attribu

 , RelativeDistinguishedName (AttributeValueAssert
 ion (attributeType 1.3.18.0.0.2216, attributeValu
 e (string "SnaNetwork"))))), actionReply (actionT
 ype 1.3.18.0.0.2222, actionReplyInfo ()))))
