1.

What is one method to keep the cache clean in IBM Integration Bus?

Define a timeout parameter in the Policy file. Use the MbGlobalMapSeccionPolicy class to expire the Global Cache variable. Set up an external process to check the variables that have not been modified in a speculated amount of time and remove them. Use remove() on the MbGlobalMap class. In case of a catastrophic crash of the node, the cache will detect this and remove the variable implicitly.

2.

What is the result of the command mqsisetdbparms -n DB2_1 -u test -p test123?

Creates a security identity for DB2_1. Sets the database parameters test and test123 for DB2_1. Connects to the database DB2_1 with user test and password test123. Creates service userld test and password test123 for the Integaration node DB2_1.

3.

In configurable services that have the UserDefined type, which node is used to read and modify properties dynamically at run time?

PHP node Mapping node Compute node Java Compute node

4.

The security team has informed the Integration Bus developers that they need to start using SSL when using the web user interface. Administration security is still disabled. What does the developer need to do to now access the web user interface?

Change the URL used to the new port being used by HTTPS. Setup a keystore on the queue manger, import the private key and then change the URL used to the new port being used by HTTPS. Have the administrator use the mqsiwebuseradmin command to create a new web user and then change the URL used to the new port being used byHTTPS. Turn on administration security, have the administrator use the mqsiwebuseradmin command to create a new web user and then change the URL used to the
new port being used by HTTPS.

5.

Which node can be used to capture failures for a sequence of nodes?

Trace Node Collector Node TryCatch Node Passthrough Node

6.

On a Linux system, trace node is configured with Destination set to a file. The trace node should be executed if a message processes successfully. A message is processed through the Integration flow successfully but no file is written. How can the problem be determined?

This error only happens if the file system is full. Check the console logs (stderr/stdout) for any errors. The only way to debug this problem is to start the flow debugger. Check the local system error logs to see if there were any errors encountered while writing to the trace node output file.

7.

What is one to set the flow debugger port?

Use the mqsichangebroker command to set the debug port. Use the mqsichangedebugport command to set the debug port. In the IBM Integration Bus Toolkit set the debug port in the Preferences. In the IBM Integration Bus Toolkit right-click on the Integration Server and set the debug port.

8.

Which is true regarding MQ topology options for IBM Integration Bus?

Only local bindings to MQ Queue Managers are supported for the MQInput node. MQ is an optional component that is not required unless using MQ transport nodes. There is a one to one relationship required between MQ Queue Manager and Integration Node. MQ can be used to create flexible connection topologies.

9.

Which statement about the DFDL parser and domain is true?

The DFDL parser is not an on-demand parser. DFDL domain is not intended for general text and binary message formats. DFDL domain is intended for parsing and writing XML or JSON formatted messages. The DFDL parser interprets a bit stream by using grammar defined in a DFDL schema file.

10.

A flow started from an MQInput Node has multiple database interactions from Compute, Java Compute and Map Nodes. All relevant node transactional properties are set to automatic. XA is not configured. Where are the transactions committed in the flow?

Both databases and the MQ transactions are committed at the end of the flow. MQ transactions are committed at the end of the flow but each database interaction is committed as the message is propagated from the Out terminal. Since there is only one MQ Node the MQ transaction is committed while propagating from the Out terminal of the MQInput Node and all the databaseinteractions are committed at the end of the flow. Each of the nodes mentioned has a Transaction property to determine the transactional nature of the node and is always committed when propagating from theOut terminal independent of any other Nodes in the flow.
