Question #: 21
Topic #: 3
A system administrator has deployed web applications to a clustered environment where database session persistence is configured. The administrator needs to improve the response time and the throughput.
How can the system administrator do this?
A.
Disable server affinity.
B.
Configure dynamic caching.
C.
Configure a load balancer to spread work between existing web servers.
D.
Tune the database session persistence to optimize for failover.
The dynamic cache service improves performance by caching the output of servlets, commands, and JavaServer Pages (JSP) files. WebSphere Application Server consolidates several caching activities, including servlets, web services, and WebSphere commands, into one service called the dynamic cache. These caching activities work together to improve application performance and share many configuration parameters that are set in an application server’s dynamic cache service.
