当JVM启动时，它寻找给定名称的类缓存(如果没有提供名称，那么选择一个默认名称)，并按照需要连接现有的缓存或创建一个新的缓存。
When the JVM starts up, it looks for a class cache of the name given (if no name is provided, it chooses a default name) and it either connects to an existing cache or creates a new one, as required.
如果PETER没有显式地指定模式，那么就会创建表PETER . TABLEA，因为在默认情况下使用连接id。
If PETER had not explicitly indicated the schema, then the table PETER.TABLEA would have been created, because the connection ID is used by default.
默认情况下，没有设置该关键字，这意味着如果目标数据库支持Unicode, DB 2 CLI应用程序就将使用Unicode进行连接。
