The screenshot in addlstandbystep4.gif is Step 4 of 6 in the Add Standby Database process. Near the top of this screenshot is a timeline indicating which step you are at in the process. As you proceed through the Add Standby Database process, the timeline will advance appropriately.
The fourth step sets up the location for standby database files. You are asked to specify the backup file access method, the standby database file location, and the network configuration file location. Standby host credentials are required to continue.
At this time, you can click Cancel, Back, or Next. If you click Cancel, you terminate the current process and must begin again at the introductory page of the Add Standby Database wizard. This scenario assumes you are continuing to the next step.
