定制，启用SACK：最后的数据集使用了引入大窗口的客户机，同时也在每次发送ack时增加四个SACK选项。
Custom, with SACK: the last data set was gathered using the large window-inducing client while also including four SACK options on every ACK sent.
修改数据集并启用参数。
如果DB 2Alphablox已安装，针对每个已安装监视器模型定义的多维数据集在默认情况下将被启用，刷新间隔为一分钟。
If DB2 Alphablox is installed, the cubes that are defined for each installed monitor model are enabled by default with a one minute refresh interval.
首次在多维数据集上启用安全性时，默认策略是ReadAllowed策略。
When security is first enabled on a cube, the default policy is the Read Allowed policy.
启用安全后，您将看到Policies选项卡上有两个多维数据集策略：ReadAllowed和ReadDenied，如图6所示。
After you enable security, you see two policies for the cube on the policies TAB: Read Allowed and Read Denied, as shown in Figure 6.
