Examples of DbConfigManager

com.sleepycat.je.dbi.DbConfigManager
DbConfigManager holds the configuration parameters for an environment. In general, all configuration parameters are represented by a ConfigParam defined in com.sleepycat.je.config.EnvironmentParams and can be represented by a property described by the EnvironmentConfig String constants. Environment parameters have some interesting twists because there are some attributes that are scoped by handle, such as the commit durability (txnSync, txnNoSync, etc) parameters. DbConfigManager is instantiated first by the EnvironmentImpl, and is loaded with the base configuration parameters. If replication is enabled, additional properties are added when the ReplicatedEnvironment is instantiated. In order to keep replication code out of the base code, replication parameters are loaded by way of the addConfigurations method.
