As you move projects from one environment to another (for example, from testing to production), you typically must modify several environment-specific values, such as JDBC connection strings, hostnames of various servers, and so on. Configuration plans enable you to modify these values using a single text (XML) file. The configuration plan is created in either Oracle JDeveloper or with WLST commands. During process deployment, the configuration plan searches the SOA project for values that must be replaced to adapt the project to the next target environment.
