Question 16: An application server is using data source connections being managed thru connection pooling.
However, the server is logging database errors resulting from lack of connections. In this context, what
applies to tuning database connections?
A. Data sources are abstracted from the JDBC drivers to permit database upgrades without impacting the
application logic. The administrator should decrease the connection timeout value.
B. The connection pool is managed by the application server container, so in addition to increasing the
connection setting, additional connections allowed must be configured on the database.
C. The data sources are released at the end of the commit phase when using Type 4 JDBC drivers. New
connections will be created upon the next database access.
D. It is necessary to tune the applications before tuning WebSphere application server. Connections not
returned to the pool are often caused by programs not closing connections properly.
Correct Answer: D
