Examples of com.sleepycat.je.Environment.openDatabase()

com.sleepycat.je.Environment.openDatabase()
Opens, and optionally creates, a Database. @param txn For a transactional database, an explicit transaction may bespecified, or null may be specified to use auto-commit. For a non-transactional database, null must be specified. @param databaseName The name of the database. @param dbConfig The database attributes. If null, default attributesare used. @return Database handle. @throws DatabaseExistsException if the database already exists and the{@code DatabaseConfig ExclusiveCreate} parameter is true. @throws DatabaseNotFoundException if the database does not exist and the{@code DatabaseConfig AllowCreate} parameter is false. @throws OperationFailureException if one of the Read Operation Failures occurs. If the database does not exist and the {@link DatabaseConfig#setAllowCreate AllowCreate} parameter is true, then oneof the Write Operation Failures may also occur. @throws EnvironmentFailureException if an unexpected, internal orenvironment-wide failure occurs. @throws IllegalStateException if this handle or the underlyingenvironment has been closed. @throws IllegalArgumentException if an invalid parameter is specified,for example, an invalid {@code DatabaseConfig} property. @throws IllegalStateException if DatabaseConfig properties are changedand there are other open handles for this database.
