You can specify if a wrapper is to be executed in the fenced mode by setting the DB2_FENCED wrapper option to ?Y? (default setting for this option is ?N? for trusted).

您可以通过将 DB2_FENCED 包装器选项设置成“Y”来指定是否以隔离模式执行包装器（该选项的默认设置是“N”，即受信任模式）。

In the previous example, the default is One-of-N policy.

在先前的实例中，缺省策略是One - of - n策略。

youdao

If not specified, the default multiplicity is 0.. n, which means as many mappings as are possible, and which is not relevant here, since a primary key is meant to be unique.

如果没有指明，默认的多重性是从0到n，这表示映射尽可能多，在这里这是无关的，因为主键意味着唯一。
