Your company wants to upgrade the production database to a Real Application Clusters (RAC)
environment. You set up the best RAC database and want to replay a recorded workload captured from the production database on the test machine.
The following steps may be used to replay the database workload:
1) Preprocess the captured workload
2) Restart the database in RESTRICTED mode.
3) Set up Replay Clients.
4) Restore the test database to the point when the capture started.
5) Remap connections.
Which is the correct sequence of the required steps?
A.1, 4, 3, 5
B.1, 4, 5, 3
C.2, 1, 5, 3, 4
D.1, 2, 4, 5, 3
数据库重放步骤:
捕获工作量--预处理工作量--重放工作量--还原数据库----连接映射--设置客户机--分析
- Resolve References to External Systems(解决对外部系统的引用)— 假设您已经在生产数据库中有了一个指向 /home/appman/myfiles 的目录对象,而测试系统上不存在该目录。在重放时,对该目录的引用将失败。同样,源系统中的所有数据库链接也将在测试系统中失败(如果它们不存在)。因此,您需要通过创建或更改目录来解决这些问题。可以利用下一个屏幕对其进行更改。
- Set Up Replay Clients(设置重放客户端)— 了解如何在后续步骤中执行该操作。
- 单击 Continue,这将显示如下所示的屏幕:
A应该是正确的,
