Deleting a IBM MQ link publish/subscribe broker profile

This describes how you delete a broker profile and all topic mappings on a Link do WebSphere® MQ, which forms a publish/subscribe bridge between WebSphere Application Server and a IBM MQ network.

Before you begin

Before you start you have to know the names of the bus, messaging engine, and Link do IBM MQ that has the broker profile that you intend to delete. You should also consider informing the IBM MQ administrator that you are about to delete the connection to the message broker in the IBM MQ network.

If you also intend to delete the associated Link do IBM MQ, you need not complete this task. Refer instead to Removendo uma Conexão de Barramento Externo de um Barramento.

About this task

Deleting a broker profile is a three-stage operation to ensure both the application server and the IBM MQ network and its message brokers are synchronized after the deletion:
  • Remove the subscriptions by unsubscribing the topic mappings on the broker profile.
  • When the Runtime view is empty, delete the broker profile.
  • If you have enabled dynamic configuration updates, the changes take effect immediately, otherwise restart the application server.
Note: If you remove the subscriptions but do not delete the broker profile, then the subscriptions are recreated when the server is restarted (because they are still present in the static configuration information for the Link do IBM MQ). These subscriptions are unrelated to the original subscriptions so this can lead to some messages in a publication flow being missing for subscribers on the target side of the bridge. For example, any messages published on an unsubscribed topic between the time the unsubscribe took place and the application server was restarted are not republished to the target side of the Link do IBM MQ.

Procedure

  1. Start the administrative console.
  2. In the navigation pane, click Integração de serviços -> Barramentos -> bus_name -> [Topologia] Mecanismos do sistema de mensagens -> engine_name -> [Propriedades Adicionais] Links do IBM MQ -> link_name -> [Propriedades Adicionais] Perfis do broker de publicação/assinatura -> profile_name.
  3. Remove the subscriptions:
    1. Click the Runtime tab.
    2. Click Subscriptions.
    3. Click Unsubscribe to remove all the subscriptions listed. When an unsubscribe command is sent to the message broker in the IBM MQ network, the relevant topic mapping is put into an indoubt state until the unsubscribe is confirmed when the topic mapping is deleted. After the unsubscribe is confirmed the topic mapping is no longer shown in the runtime view. You might have to refresh the runtime view for all subscriptions to be shown as removed.
  4. Delete the broker profile:
    1. Return to the Publish/subscribe broker profiles page.
    2. Select the check box next to the broker profile you want to delete.
    3. Click Delete.
  5. Salve suas alterações na configuração principal.
  6. Optional: If you have enabled dynamic configuration updates, the changes take effect immediately. Otherwise, restart the application server.
