Use the mqsisetdbparms command to associate a specific user ID and password (or SSH identity file) with one or more resources that are accessed by the broker.

The three stages of creating a user-defined pattern are performed by the IBM Integration Bus developer, the pattern author, and the pattern user.

Setting up message flow security

Set up security on a message flow to control access based on the identity of a message passing through the message flow.

You can configure the broker to perform end-to-end processing of an identity carried in a message through a message flow. Administrators can configure security at message flow level, controlling access based on the identity flowed in a message. This security mechanism is independent of both the transport and the message format.

To work with an identity, you must configure the policy sets and bindings for the relevant capabilities:

To configure monitoring on a message flow to emit events for capture, use one of the following methods.

Use the CMP in a JavaCompute node to query, set, create, and delete properties dynamically at run time in configurable services that you have defined with type UserDefined.

If you do not wire a Failure terminal, a failure in the node is converted into an exception which is thrown from the node.

You can also use the Trace node to provide information in error handling in your message flows. For example, you can use this node to record failures in processing because of errors in the content or format of a message.

You can prevent the transaction from being rolled back, and control the extent to which message changes are reversed, by including a TryCatch node in your message flow. If an exception is thrown beyond the Try terminal of the TryCatch node, then an exception list is propagated to the node's Catch terminal. The inflight message reverts to the state it was in before it reached the TryCatch node.

Most message flow nodes have a Catch terminal. These nodes are typically at the start of a transaction, where an uncaught exception would cause a rollback. In these nodes, the Catch terminal behaves as though a TryCatch node was wired directly to the Out terminal. Use the Catch terminal to handle any exceptions that are thrown beyond the message flow node. Wire the Failure terminal to handle errors within the node itself.

The DFDL parser is model-driven.

Choose an external grid if you have any of the following requirements:

You have an architectural preference for the cached data not to be placed in the integration servers themselves.

You want to separate the availability of the cache from the availability of the integration servers.

You need an enterprise cache, with multiple applications (other than IBM Integration Bus) that are accessing the data.

You have (or want) sophisticated, or custom, tools to manage the cache.

The cache needs to span multiple data centers for disaster recovery.

You need to configure the grid for specific capabilities that are not supported by the embedded global cache.
