Step S101, the message listener monitoring information queue in ac server, the message stored in the message queue
It is the first JMS service device in OMC server according to the generation of the data synchronization request of reported by network elements, the data synchronization request
Middle carrying network element data；
Step S102, the message that the second JMS service device in the ac server is listened to according to the message listener
The NE database of the ac server side is updated, the NE database is for storing network element data.
Wherein, need to predefine the messaging protocols between them between OMC system and ACS system first.Consider
Two kinds of message model Point-to-Point (P2P) and Publish/Subscribe (Pub/Sub) are supported to JMS operation system,
That is ad hoc mode and two kinds of distribution subscription model.Specifically, in P2P mode, comprising: message queue (Queue), sender
(Sender), recipient (Receiver).Each message is sent to a specific queue, and recipient obtains from queue
Message.Queue maintains message, until they consumed or time-out；In Pub/Sub mode, comprising: theme (Topic), hair
Cloth person (Publisher), subscriber (Subscriber).Multiple publishers send a message to Topic, and system is by these message
Pass to multiple subscribers.
Therefore before step S101, further includes: ac server sends to OMC server and subscribes to request, and the subscription is asked
Seek the message of the designated key for the OMC server publication that pulls subscription.

(QueueConnectionFactory)
context.lookup(queueConnectionFactoryName)；
QueueConnection queueConnection=queueConnectionFactory.
createQueueConnection()；
queueConnection.start()；
QueueSession queueSession=queueConnection.createQueueSession
(transacted,
acknowledgementMode)；
Queue queue=(Queue) context.lookup (queueName)；
Wherein, the far-end IP address in the MDB example be configured as the OMC server IP address and the MDB
Distal end slogan in example is configured as the port numbers of the OMC server, it is contemplated that ACS system and OMC system can portions

Enterprise Java Bean container is carried, each MDB can only handle a piece of news, in order to realize concurrent processing message, include in the Enterprise Java Bean container
At least one MDB example.
The network element data synchronization carried out between the OMC system and ACS system by asynchronous remote method of calling, network element are set
The standby JMS message that will carry network element data is sent to target MQ by the first JMS service device, and the target MQ is initialized in JMS
When by context search obtain.OMC server receives the JMS message of carrying network element data from target MQ, updates OMC
The database of system, operator obtain network element data from OMT interacting, and the JMS message is one of JMS type
Object is made of header and source body two parts.Metadata of the header by routing iinformation and in relation to the message forms.Message
Main body then carries the data or payload of application program.It is divided, message can be divided into according to the type of payload
Several types, they are carried respectively: plain text (TextMessage), the object (ObjectMessage) of serializability, category
Property set (MapMessage), byte stream (BytesMessage), original value stream (StreamMessage), also whether there is or not effectively negative
The message (Message) of load.
Because in the Enterprise Java Bean container of ACS system including at least one MDB example, the MDB defines a message and monitors
Device, the message listener monitor target MQ, when interface class javax.jms.MessageLister listens to message and arrives in MDB
Up to when, the first JMS service device is by calling the onMessage in the interface class javax.jms.MessageLister
() method transmits message, and the JMS message listened to is transmitted to client 2 by the second JMS service device, operator from visitor
