Depending on your current version of IBM® Integration Bus, IBM App Connect Enterprise Version 11.0 might introduce several technical changes in behavior. These changes might affect your post-migration development tasks.
For detailed information about the platforms that are
supported, visit the IBM App Connect
Enterprise Version
11.0 system requirements web
page.
The Statement of general direction in the IBM App Connect
Enterprise Version
11.0 announcement
letter outlines intention regarding support for other platforms.
At earlier releases, configurable services allow you to control and update connection properties and other operational properties of message flows and message flow nodes at run time. In IBM App Connect Enterprise Version 11.0, policies perform this administrative role.
You can migrate your existing configurable policies by using the mqsiextractcomponents command. If you are performing parallel migration, you need to create policies to replace your configurable services.
For more information, see Overriding properties at run time with policies.
Your message flows from earlier versions will work at IBM App Connect Enterprise Version 11.0. However, a number of message flow nodes are unavailable at Version 11.0; if your earlier message flows include them, consider reworking them.
For details of other nodes that are unavailable in IBM App Connect Enterprise Version 11.0, see Built-in nodes.
Multi-instance integration nodes and the HTTP proxy servlet are not currently supported. You can, however, use an external HA manager or a Windows Cluster.
For more information, see Using an integration node with an existing high availability manager and Using an integration node with an existing Windows Cluster (Windows Server).
IBM App Connect Enterprise Version 11.0 does not include the IBM Integration API. Instead, you can use the REST API (Version 2) that is provided in IBM App Connect Enterprise Version 11.0 to issue administration commands.
For more information, see Managing resources by using the administration REST API.
IBM App Connect Enterprise Version 11.0 does not include IBM Integration Explorer. Instead, the web user interface is extended to support integration node administration tasks such as creating and managing integration servers, and deploying and managing resources.
For more information, see IBM App Connect Enterprise web user interface.
In IBM App Connect Enterprise Version 11.0, you have two options for configuring administration security. As in previous versions, you can configure queue-based permissions by using WebSphere MQ queues on the queue manager that is specified on the integration node, or you can configure file-based permissions on your integration node, which you set by using the mqsichangefileauth command.
If you have configured administration security and then you perform parallel migration to integration nodes that are not configured with queue managers, you must reconfigure your administration security to use file-based permissions. Any security permissions that are set before migration are not retained after migration.
For more information, see Authorizing users for administration.
A number of commands are not available at
this release. In addition, some parameters for administration commands
that connect to integration nodes and integration servers have changed;
see the command reference topics for more information: Commands. The MQBrokerConnectionParameters IBM Integration
API class has also been deprecated;
see the Javadoc for the IBM Integration
API.
By default, the IBM App Connect Enterprise Toolkit is now configured to use online product documentation to provide context-sensitive help from the latest information that is available. In previous versions, the IBM App Connect Enterprise Toolkit contained local help documentation, which was not automatically updated when new information became available. There is no difference in the way that help is displayed in the IBM App Connect Enterprise Toolkit. However, the content of the IBM App Connect Enterprise section of the online product documentation is updated when fix packs are made available. If you have not deployed the latest fix pack, the help information might include details of function that is not available to you.
If you do not want to access the online product documentation, you can download and install a local source of product documentation. For information about local documentation options, see Adding documentation to the IBM App Connect Enterprise Toolkit.
In IBM App Connect Enterprise Version 11.0, message maps are prepared for execution on deployment instead of when the first message flows through the Mapping node. For more information, see Deploying message maps.
