Nastavení zásad WS-ReliableMessaging

For the WS-ReliableMessaging policy you can configure the version of the WS-ReliableMessaging standard that you want to use, the option to use the WS-MakeConnection protocol for synchronous two-way message exchange, the order in which messages are delivered, and the required quality of service (the reliability level) for message delivery.Produkt vynucuje tyto zásady u příchozích zpráv a uplatňuje je na odchozí zprávy.

To view this pane in the console, click the following path: Services > Policy sets > Application policy sets > policy_set_name > [Policies] WS-ReliableMessaging.

With WebSphere Application Server, you can use WS-ReliableMessaging with Java API for XML-Based Web Services (JAX-WS) 2.0 Web services applications that use a SOAP over HTTP binding. To configure a Web service application to use WS-ReliableMessaging, you attach a policy set that contains a WS-ReliableMessaging policy type. This policy type offers a range of qualities of service: managed persistent, managed non-persistent, or unmanaged non-persistent.

Do not edit the policies associated with the provided default policy sets. If you need to modify the reliable messaging policy settings, use a copy of a default policy set or create a new policy set.

Karta Konfigurace

Standardní
Select the WS-ReliableMessaging specification to use for reliable transmission of your messages. WS-ReliableMessaging Version 1.1 is the default value. Details of the supported WS-ReliableMessaging specifications are available at the following Web addresses:
  • The WS-ReliableMessaging specification Version 1.0, February 2005.
  • The OASIS WS-ReliableMessaging specification Version 1.1, February 2007.
Poznámka: If you plan to invoke a .NET-based Web service or host a Web service that is compatible with reliable .NET clients, you must select WS-ReliableMessaging Version 1.0.
Povolit příkaz MakeConnection pro synchronní výměnu dvoucestných zpráv

Select this option to enable WS-MakeConnection, which is a standard method of enabling synchronous two-way message exchange with WS-ReliableMessaging.

For more information, see the WS-MakeConnection specification Version 1.0, February 2007.

Poznámka:
  • If you are using WS-ReliableMessaging Version 1.1 and you want to use synchronous two-way message exchange, you must enable "MakeConnection".
  • If you are using WS-ReliableMessaging Version 1.0, you cannot use "MakeConnection".
  • If you want to use "MakeConnection" you must also include the WS-Addressing policy in the policy set.
Doručovat zprávy v pořadí, v jakém byly odeslány

Select this option if the sender of a request has to receive a response before it sends the next request.

Při povolení postupného doručení je rovněž nutné zajistit, aby aplikace klienta vyzývala zprávy v pořadí, v jakém mají být přijaty. Další informace naleznete v dokumentu Configuring the WS-ReliableMessaging policy.

Postupné doručení také mírně zvyšuje spolehlivost při použití spravované trvalé kvality služby. Další informace naleznete v dokumentu A message is not recovered after a server becomes unavailable, even with the managed persistent quality of service.

Kvalita služby
Vyberte jednu z následujících kvalit služby:
Nespravovaná přechodná - toleruje selhání sítě a vzdáleného systému
You can configure Web service applications to use WS-ReliableMessaging with a default in-memory store. This quality of service requires minimal configuration. However it is non-transactional and, although it allows for the resending of messages that are lost in the network, if a server becomes unavailable you will lose messages. This quality of service is for single server only and does not work in a cluster. This quality of service is not supported on the z/OS platform. Výchozí hodnota je Nespravovaná přechodná.
Spravovaná přechodná - toleruje selhání systému, sítě a vzdáleného systému, stav je však zahozen po restartování stroje systému zpráv
This in-memory quality of service option uses a messaging engine to manage the sequence state, and messages are written to disk if memory is low. This quality of service allows for the re-sending of messages that are lost in the network, and can also recover from server failure. However, if a server becomes unavailable you will lose messages. This option supports clusters as well as single servers.
Spravovaná trvalá - toleruje selhání systému, sítě a vzdáleného systému
This quality of service for asynchronous Web service invocations is recoverable. This option also uses a messaging engine and message store to manage the sequence state. Messages are persisted at the Web service requester server and at the Web service provider server, and are recoverable if the server becomes unavailable. Messages that have not been successfully transmitted when a server becomes unavailable can continue to be transmitted after the server restarts.
Poznámka:
  • All three qualities of service are supported when applications are deployed to the application server. Thin client and client container applications use the first option only.
  • For the unmanaged non-persistent quality of service, the messages are stored only in memory. For both of the managed qualities of service, the messages are managed by a messaging engine backed by a message store. Vazba sběrnice a stroje systému zpráv se určuje ve formuláři Nastavení zásad WS-ReliableMessaging (vazby doručení). Při výběru kvality služby typu Nespravovaná přechodná jsou veškeré určené vazby ignorovány.
