Next, an application named AppB issues this statement.

youdao

Prior to DB2 9.7, the statement issued by AppB would hang because it would wait for the exclusive lock held by the update statement of AppA (the writer) to be released.

在DB 2 9.7之前，AppB发出的语句会被挂起，因为它要等待释放AppA (writer)的update语句持有的排他锁。

youdao

When you enable this new CS behavior (it is the default behavior for new DB2 9.7 databases), the statement from AppB returns the currently committed value, instead of waiting.

如果启用这个新的CS行为(在新的DB 2 9.7数据库中这是默认行为)，AppB发出的语句返回当前提交的值，而不需要等待。
