Examples of com.sleepycat.db.EnvironmentConfig

com.sleepycat.db.EnvironmentConfig
omize an environment configuration EnvironmentConfig envConfig = new EnvironmentConfig(); envConfig.setTxnTimeout(10000); // will throw if timeout value is invalid // Open the environment. Environment myEnvironment = new Environment(home, envConfig);
Additional parameters are described in the example.properties file found at the top level of the distribution package. These additional parameters will not be needed by most applications. This category of properties can be specified for the EnvironmentConfig object through a Properties object read by EnvironmentConfig(Properties), or individually through EnvironmentConfig.setConfigParam().
For example, an application can change the default btree node size with:
```
 envConfig.setConfigParam("je.nodeMaxEntries", "256"); 
```
Environment configuration follows this order of precedence:
1. Configuration parameters specified in <environment home>/je.properties take first precedence.
2. Configuration parameters set in the EnvironmentConfig object used at Environment construction are next.
3. Any configuration parameters not set by the application are set to system defaults, described in the example.properties file.
An EnvironmentConfig can be used to specify both mutable and immutable environment properties. Immutable properties may be specified when the first Environment handle (instance) is opened for a given physical environment. When more handles are opened for the same environment, the following rules apply:
1. Immutable properties must equal the original values specified when constructing an Environment handle for an already open environment. When a mismatch occurs, an exception is thrown.
2. Mutable properties are ignored when constructing an Environment handle for an already open environment.
After an Environment has been constructed, its mutable properties may be changed using {@link Environment#setConfig}.
