IBM WebSphere Application Server Network Deployment V8.5 and V9.0, Core Administration — Question 15

An administrator upgrades the IBM DB2 JDBC driver. The test connection operation fails. On checking the System.Out log the administrator finds that the JVM is still using the old JDBC driver.
What could be the possible reason for the failure?

Answer options

• A. No driver JARs exist.
• B. The driver upgrade failed.
• C. There are multiple drivers in the provider classpath.
• D. DB2UNIVERSAL_JDBC_DRIVER_PATH was NULL.

Correct answer: B

Explanation

The correct answer is B because if the driver upgrade was unsuccessful, the old JDBC driver would continue to be used, leading to connection failures. Options A, C, and D do not directly address the issue of the upgrade process itself failing, which is the core problem in this scenario.
