IBM WebSphere Application Server Network Deployment V8.5 and V9.0, Core Administration — Question 7

An administrator configures an IBM DB2data source at cell scope. The environment variable DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope. The data source test connection on one node succeeds, but fails on the other node with java.lang.ClassNotFoundException:com.ibm.db2.jcc.DB2ConnectionPoolDataSource.
Which of the below is the likely cause for the exception?

Answer options

• A. The data source is configured at cell scope.
• B. Multiple driver JARs are installed on the second node.
• C. DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope.
• D. A different version of the JDBC driver JAR does not exist on the second node.

Correct answer: C

Explanation

The correct answer is C because the DB2UNIVERSAL_JDBC_DRIVER_PATH needs to be accessible at the node level for the JDBC driver to be found. Option A is incorrect since the data source's configuration scope is not the issue. Option B does not address the path configuration problem, and option D suggests a missing driver version, which is not indicated in the scenario.
