Eclipse 3. However, when you attempt to install a plug-in, any plug-ins that it depends on must already be installed. However, straight passthrough of encoded envelopes without manipulation in the message flow does work. The limitations are grouped in the following sections:. In general, it is not advisable to specify the same directory location for your poller and archive file locations when you design a proxy service with a file transport.
Version Utility weblogic. Version information for AquaLogic Service Bus is contained in the version. For Windows, use setDomainEnv. Invoke java weblogic. The version information for AquaLogic Service Bus is now displayed. Note: The Service Bus version. The correct name and version is "AquaLogic Service Bus 2. If you have a WSDL that has two operations with the same input message, do not choose the SOAP Body Type selection algorithm for operations, because the operation cannot be uniquely identified by inspecting the input message.
AquaLogic Service Bus' validation algorithm does not identify this scenario, and does not prevent users from selecting this algorithm. Do not write recursive XQuery statements when you design your proxy services. Any inconsequential change to the WSDL will do for example, add a space. Keep the name and path of proxy services short for successful deployment on Windows machines, as there is a system path length limitation on Windows machines. You cannot start an AquaLogic Service Bus domain with weblogic.
LoggingResourceException when you move a domain template to a different machine and use the template to create the new domain. The scenario is as follows:. Start the server for the original domain. At this point, the domain is now "used"—a domain is considered used once you have started the server for a domain after you have created it.
Create the domain template. Create a new domain using the template. Start the server for the domain. If the new domain does not have the same name as the initial domain, the new domain cannot be started. LLR does not allow this to prevent different domains from corrupting each other's tables.
Workaround: You must use the same domain name when you create the new domain using the same template on a different machine. Alternatively, change the name of the LLR table that the new domain uses.
Therefore, if you replicate a domain that has WebLogic JDBC stores configured without renaming the store tables or without using a different database user and schema for the new store's connection pool, data corruption occurs if both the old and the new domains remain active. Similarly, corruption without warnings may occur if same-named WebLogic file stores share the same directory.
When a session is activated, AquaLogic Service Bus acquires a WebLogic Server lock that is held throughout the activation, and then released when the activation completes successfully or not. However, if the administration server crashes before the session activation completes, the lock is not released automatically when you restart the server. This lock prevents further session activations. Workaround: WebLogic Server regular pinned destinations, WebLogic Server distributed destinations in a different cluster, and non-WebLogic Server destinations may be configured as response destination.
A Messaging Proxy Service still receives and routes messages after it has been deleted if the user sends messages to it. When you create a non-system fault in AquaLogic Service Bus, you cannot use the default system prefix soap-env for the namespace. You must declare a new namespace prefix and use it in the faultcode. For example:. For information about the patch, see AquaLogic Service Bus 2. This problem prevents interoperating with encoded web services, either RPC encoded or Document encoded.
In addition, this is a factor that causes problems in interoperating with. Failure to do so will leave the security policy in the authorization-provider database and potentially cause unexpected results and potential security vulnerabilities.
When using the built-in XQuery function fn-bea:lookupBasicCredentials , the username and password associated with a service account is sent in clear-text in the SOAP envelope.
This risk is reduced by the fact that only AquaLogic Service Bus administrators can edit Proxy service message flows and deploy configurations to AquaLogic Service Bus. Inbound Web Service Security does not work on the same operation if the WS-Policy on the request specifies digital signature and the WS-Policy on the response specifies encryption. This limitation applies to active intermediary scenarios only, it does not apply to pass-through scenarios.
A bug exists in the client-side Web Service Security run time that causes X. The credential provider list is passed to the client as the value of the property named weblogic. ContextHandler; import weblogic. WSSConstants; import weblogic. CredentialProvider; import weblogic. It is possible for this certificate to get out-of-sync with the actual certificate used by the business service.
In this case, the proxy service encrypts with the wrong key and routes the message to the business service. However, the business service is unable to decrypt the message. This scenario is difficult to debug. If the target service is a WebLogic Server 9. If you add or delete a security provider, you must reboot the server for the security changes to take effect. In particular, if you configure a new PKI credential mapper and fail to reboot the server, you will get an exception whenever you access any page in the Credentials section of the AquaLogic Service Bus.
The Credentials section will be available again after you reboot the server. AquaLogic Service Bus Servers are configured with a clear-text listen port by default. An additional SSL listen port can be configured.
The clear-text listen port is required—do not disable it. Failure to do so results in AquaLogic Service Bus continually reporting the error as an exception. You can correct this problem in the AquaLogic Service Bus Console by assigning the username and password to the service account in the Credentials section of the Security Configuration module. The administration server does not have to be restarted. Note: There are other conditions that can cause the same problem of continuous run-time exceptions.
To avoid this problem again, we recommend that you configure JMS queues to have a limited number of retries. A problem exists when using a JMS Control to send and receive messages to and from remote queues on a server in a WebLogic 8. Enabling WebLogic Server 8. To achieve full interoperability between WebLogic 8. A known problem exists when sending SOAP 1. DataHandler always returns null. However, if your use case requires this functionality, contact your BEA Customer Support representative and request an update on the status of CR A "Graphics Library Disabled" image is displayed instead of pie and bar charts in the Monitoring module if the Graphics Library cannot be initialized in a Linux environment.
The problem may be that the graphics library support X11 toolkit is not installed on your machine. Isolate the libraries required for installing the X11 toolkit or the native graphics library for Linux.
When you click Save on the View Policy Details page for transport policies or service policies in the Security Configuration module, your browser continues to display the same page instead of returning to the Access Control for Proxy Services page. The Access Control for Proxy Services page is displayed.
You can also click a navigation link on the top of the page, then navigate to the Access Control for Proxy Services page. When you delete an alert in the Monitoring module, the alert count on the Alert Summary page may not be immediately reduced. This behavior is seen in situations where a large number of alerts are being generated. The reason for this is when an alert is generated, the data record is stored in a memory cache before it is written to a repository after a time interval.
When you delete an alert on the console, the alert record is marked in the memory cache for deletion in the alert repository. Because there is a delay in flushing out this marked record to the repository from memory cache, the deleted alert is displayed on the console until it is flushed from the memory cache.
Workaround: Refresh the console after you delete the alert. After minutes, the deleted alert is no longer included in the alert count. A blank page is displayed when you make an invalid selection in the Purpose of this Credential dropdown list in the Credentials section of the Security Configuration module. Workaround: Click the Back button in your browser, then make a different selection in the Purpose of this Credential dropdown list.
Because a proxy service may receive BytesMessage, encoding information is required to correctly interpret those bytes. When you use the search filter to retrieve or purge messages in the Reporting module, if you specify the same start and end times to filter messages for a specific minute, the search filter returns zero messages even if there are reporting messages with that timestamp.
For example, if you specify 7. The reason for this issue is that messages are persisted in the database with timestamps up to the second, whereas on the AquaLogic Service Bus Console the messages are displayed with timestamps up to the minute only. Workaround: Specify the end time at least one minute after the start time. For example, if you specify the start time as 7. In the event that a managed server in your cluster is stopped and then restarted, fewer message counts and alert counts may be displayed in the Dashboard Monitoring Summary page than were displayed before the managed server went down.
Because only statistic summary information is written to disk and recovered after a failure, it is necessary to approximate some of the data during the server restart.
This can result in the slightly reduced counts. The accurate counts are available again after a full aggregation interval has elapsed. If you enter a four digit number for the year, it is persisted correctly and the rule is evaluated correctly against the entered date. However, the AquaLogic Service Bus Console interprets only the last two digits of the date entered and can incorrectly flag the rule as Expired.
Additionally, if you enter a two digit number for the year and the entered date occurs in the past, the date is correctly displayed as Expired in the AquaLogic Service Bus Console but is incorrectly persisted as belonging to the next century and the rule is not considered expired at run time.
AquaLogic Service Bus supports dynamic content-based routing of messages and run-time protocol selection. It facilitates these capabilities by allowing the configuration of proxy services with interfaces that are independent of the end-point business services.
Using generic proxy templates, proxy services can be configured as message-flow definitions with routing logic that dynamically route messages to appropriate business services, based on message content. AquaLogic Service Bus supports the following capabilities for the transformation or processing of messages:. AquaLogic Service Bus provides a service callout action that offers greater flexibility for more sophisticated message flows for complex dynamic-routing processing, or to perform message enrichment.
The service callout action is used inside a message flow routing stage, to call on the destination service to perform some action on the message. This can be used for message enrichment, for routing decisions or for customizing the behavior of a proxy service. Read-access to databases from proxy services is supported without requiring writing of a custom EJB or custom Java code and without the need for a separate database product like AquaLogic Data Services Platform.
It is implemented using the execute-sql function to make a JDBC call to a database to perform simple database reads. This allows a more efficient and flexible approach to accessing data services than exposing them as Web services via WebLogic Workshop and Java Web Services JWS , and it supports security and identity propagation.
Eclipse 3. An EJB can be exposed as a Web service, without the need for tools or the modification of the legacy code on the application server that hosts the EJB.
The EJB transport provides the following capabilities:. AquaLogic Service Bus supports open industry standards for ensuring the integrity and privacy of communications and to ensure that only authorized users can access resources in an AquaLogic Service Bus domain.
It uses the underlying WebLogic security framework as building blocks for its security services. The WebLogic security framework divides the work of securing a domain into several components providers , such as authentication, authorization, credential mapping, and auditing. AquaLogic Service Bus provides the following security features:. The AquaLogic Service Bus security model includes the following:.
The Change Center has the unique ability to lock its current configuration while changes are being made, letting the service bus continue to receive and process requests for services while configuration changes are being made in the console.
The service bus uses the new service and resource configuration when changes are activated. This way, ongoing changes can be made without disrupting services. AquaLogic Service Bus built-in test console is a browser-based test environment used to validate resources and inline XQuery expressions used in the message flow. Using the test console, it is possible to configure the test object proxy service, business service, XQuery, XSLT, MFL resource , execute the test, and view test results.
It allows message flow tracing when testing a service, to examine the state of the message at specific trace points. Design time testing helps isolate design problems before deploying a configuration to a production environment. The test console can test specific parts of a system in isolation and it can test a system as a unit. AquaLogic Service Bus provides the following resource management capabilities:. The supporting APIs allow loading ZIP files containing resources, in addition to moving, renaming, cloning, or deleting resources, folders and projects.
AquaLogic Service Bus supports the following error handling capabilities:. AquaLogic Service Bus allows the following capabilities for auditing and monitoring services:.
Both business services and AquaLogic Service Bus proxy services are monitored, as are response times, message counts, and error counts. This API enables integration with management partners and enables customers who have their own monitoring consoles to display metrics that can be used for performance analysis.
It provides operational functions and settings that allow users to easily search for resources using the new SMart Search functionality, monitor SLA alerts, pipeline alerts, logs, reports, turn tracing on and off, and to enable and disable services.
Operators have privileges to edit operational settings, create new SLA alert rules, and create and edit alert destination resources.
AquaLogic Service Bus provides the ability to deploy new versions of services and allows you to have multiple versions of message resources such as WSDLs and schemas. Versions can include changes to the WSDL, the message schema, the headers, and the security parameters.
In AquaLogic Service Bus, monitoring statistics are gathered locally and aggregated centrally. SLA rules are run against aggregated data and the system raises alerts, following which services can be enabled or disabled. Administrators can set service level agreements SLAs on the following attributes of proxy services:. AquaLogic Service Bus is designed to centrally manage and control many distributed service endpoints.
These instances have their own sets of configuration artifacts such as services and transformations. Such deployments typically map to various IT departments within an organization.
Communication between different departments is achieved through a federated network of ESBs, which talk to each other, often through firewalls. AquaLogic Service Bus enables management and coordination of many distributed service endpoints, thereby providing centralization in the enterprise.
A cluster consists of a set of clustered managed servers that perform message processing. A domain can have only one cluster with AquaLogic Service Bus deployed to it. This cluster can host other applications in addition to AquaLogic Service Bus. There is one administration server in every clustered domain. It propagates configuration and metadata automatically to the managed servers for fast local retrieval, and it automatically collects monitoring metrics from all the managed servers for aggregation and displays them on the AquaLogic Service Bus Console.
The following figure shows the flow of message data in a basic AquaLogic Service Bus cluster topology. AquaLogic Service Bus enables reliable and guaranteed messaging through the federated network through JMS store and forward. The dynamic routing capability also simplifies configuration of such a network. Spreading the messaging load homogeneously over the clustered servers prevents bottlenecks in the system.
AquaLogic Service Bus supports best practices for change management in enterprise systems by configuration of resources and services in a controlled environment.
It allows export of system configurations into separate staging domains for testing and final preparation for promotion into a production domain.
Java programs or scripts can be used to automate deploying an application or for moving a configuration from staging to production. An extended list of environment variables allows settings to be preserved or tailored when moving from one environment to another. An important part of large scale development is the ability to develop, test, stage, and deploy resources to a production system. This functionality supports an orderly promotion process of AquaLogic Service Bus resource configurations from staging and test environments into production and minimizes the expertise, time, and resources needed to achieve various deployment scenarios.
In addition to exporting and importing resources, it is also permitted to export and import entire projects. Using the features of existing source code control system in conjunction with the configuration JAR files, provides version and change management for AquaLogic Service Bus configurations.
This capability allows system configuration to be propagated from one instance of AquaLogic Service Bus to another instance by exporting all, or a subset of, the resources deployed in the source AquaLogic Service Bus domain. There are no restrictions on what can be exported.
One or more projects, or select resources from one or more projects can be exported. The AquaLogic Service Bus Console also allows export of a resource and all the other resources on which it depends, using the dependency tracking feature. It is necessary to be working outside a session to export configurations.
Only configurations that have been activated that is, deployed to run time can be exported. There are two types of operational values: Global Operational Settings and operational values for proxy and business services. Global Operational Settings is a resource located in the System project folder and can be exported like any other resource. It is possible to preserve operational settings in the importing domain from being overwritten during import. The Import feature provides the ability to import resource configurations into a session on another AquaLogic Service Bus domain.
To use the Import feature, it is necessary to be working in the session into which the configuration JAR file is to be imported. Many configuration updates and import of multiple JAR files is permitted in a single session. It is also possible to import only a subset of the exported data.
AquaLogic Service Bus provides the ability to reconfigure environment-specific elements as necessary to meet the requirements of the importing domain, using the Change Center in the AquaLogic Service Bus Console. Using this customization feature, imported resources can be tailored for the new domain before activating them. It supports the global change of environment-specific attributes for resources, using the import functionality along with the find and replace feature.
This facilitates changing of many similar environment values in a convenient way. It is not meant to replace a more careful tuning of configuration that may be required by complex deployment scenarios. This script outputs the product breadcrumb required for edocs documentation. Processing of the inbound transport Message flow execution Processing of the outbound transport.
A pipeline pair , one for the request and one for the response. The pipelines consist of a sequence of stages that specify actions to perform during request or response processing.
