The three stages of creating a user-defined pattern are performed by the IBM Integration Bus developer, the pattern author, and the pattern user. The IBM Integration Bus developer develops the exemplar. The exemplar is fundamental to the pattern authoring process. It assumes that the exemplar is the starting point for a pattern. Some modifications might be required to the exemplar to prepare it for pattern authoring. The pattern author creates a pattern plug-in from the exemplar. The pattern user receives a user-defined pattern, customizes it, and uses it in accordance with the requirements of the organization. References: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_9.0.0/com.ibm.etools.mft.doc/bc68380_.htm

Enabling cache preloading After the query file is created and placed on the server, configure the broker to use the text file at execution group start up. The change properties command will be used to achieve this and is accomplished by running the following command:Command to enable preloading of the WSRR cache from file mqsichangeproperties <broker_name> -c ServiceRegistries -p "<wsrr_query_text_file>" -o DefaultWSRR -n predefinedCacheQueries Replace <broker_name> with the name of the broker that is being used. Replace <wsrr_query_text_file> with the absolute file path location and name of the query file. References: https://www.ibm.com/developerworks/websphere/library/techarticles/1404_smithson7/1404_smithson7.html

Cloning a .NETInput node You can reproduce parameters and attributes that you customized for a .NETInput node by creating a Cloned node from it. The Cloned node has no special properties of its own, and cannot be created from the palette drawer. You can create it only from an existing, configured .NETInput node. You must have administrator privileges to be able to create a Cloned node. References: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_9.0.0/com.ibm.etools.mft.doc/bc16290_.htm

Set the Aggregate Name property of the AggregateReply node to the same value that you set for the Aggregate Name property in the corresponding AggregateControl node in the fan-out flow. References: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_9.0.0/com.ibm.etools.mft.doc/ac12311_.htm

Use the IBM Integration Explorer to export a configurable service to use on another integration node (broker). References: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_9.0.0/com.ibm.etools.mft.doc/be10390_.htm

The MQInput node takes certain actions when handling errors with persistent and transactional messages. The node attempts retry processing when a transactional message is rolled back to the input queue. Non-transactional messages are not rolled back to the input queue when an exception occurs. If the MQInput node has successfully propagated the message to the out terminal and an exception is thrown in the out flow, the message is returned to the MQInput node:If you have not connected the Catch terminal, the message is rolled back to the input queue. The MQInput node writes the error to the local error log and invokes the retry logic, described in Handling retry processing. If you have connected the Catch terminal, you are responsible for handling the error in the flow connected to the Catch terminal. The broker creates a new exception list to represent the error and this list is propagated to the Catch terminal as part of the message tree, but neither the MQInput node nor the broker provide any further failure processing. References: https://www.ibm.com/support/knowledgecenter/SSMKHH_9.0.0/com.ibm.etools.mft.doc/ac00414_.htm

Before you deploy message flows that contain a DecisionService node, you must enable the mode extension by using the mqsimode command:mqsimode -x DecisionServices Incorrect Answers:A: The mqsicvp command is run automatically when you start a broker by using the mqsistart command. The command checks that the broker environment is set up correctly. This checking has been enhanced to verify that the ODBC environment is configured correctly on Linux and UNIX systems.References: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_10.0.0/com.ibm.etools.mft.doc/bc23793_.htm

References such as '6.14' apply to the row and column number within a function that specify the location of the command that is being executed; in this case, row 6, column 14. Example:2005-07-12 16:17:18.242605       5344   UserTrace   BIP2539I: Node 'Reply.MapToRequestor':Evaluating expression ''I'' at ('.MapToRequestor.CopyMessageHeaders', '6.12'). This resolved to ''I''. The result was ''1''.  References: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_9.0.0/com.ibm.etools.mft.doc/au14320_.htm

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 work with a SAML assertion, configure the policy sets and bindings for SAML token capabilities. To work with an X.509 Certificate identity, configure the policy sets and bindings for X.509 certificate token capabilities. To work with a Username and Password identity, configure the policy sets and bindings for Username token capabilities. To work with an LTPA token, configure the policy sets and bindings for LTPA token capabilities. To work with a Kerberos ticket, configure the policy sets and bindings for Kerberos token capabilities. References: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_9.0.0/com.ibm.etools.mft.doc/ap04170_.htm

You can use the message flow statistics data to help you identify aspects of a message flow that might be reducing the performance of the flow, and to help you understand how you can optimize it. If you detect that system resources are under pressure, you can examine the statistics collected by the broker to assess whether the cause of the concern is the use of those resources by processes in IBM Integration Bus. References: https://www.ibm.com/support/knowledgecenter/en/SSMKHH_9.0.0/com.ibm.etools.mft.doc/bj43310_.htm
