Configuring JBoss EAP Pool Attributes

JBoss Enterprise Application Platform can deploy and manage any Java application you have as part of your stack — and to really optimize our performance, we want to leverage one of JBoss EAP's principal tools, connection pools. Connection pools work with datasources and resource adapters to reduce the cost of connections by pooling all connections available on the application. In this lab, we configure the connection pools for two datasources, both on the CLI and the Console.
