Using SACR requires two steps.

使用SACR需要两个步骤。

It is here that the benefits of SACR become clear.

这使SACR的优点变得更清晰。

SACR enabled, and data distributed randomly across nodes.

启用了SACR，并且数据随机分布在所有节点上。

But applications with a greater mix of random and non-random queries can also see performance improvements from SACR.

但是，即使应用程序包含更多的随机查询，它也可以借助SACR获得性能提升。

Because SACR is application transparent, no changes are needed to applications in order for them to be used with SACR.

因为SACR对应用程序是透明的，为了对应用程序启用SACR，无需对应用程序作任何更改。

When SACR is enabled, DB2 chooses a coordinator for the transaction based on the data location of the first statement.

在启用SACR时，DB 2基于第一条语句的位置选择了一个事务协调者。

The more affinity the requests within a transaction have to a single node, the more an application will benefit from SACR.

同一个事务中的请求越集中在一个节点上，应用程序从 SACR 中受益越多。
