When an outage occurs at the primary site, the apps switch automatically to the standby site although a manual process is available if preferred.

With olap4j, you can switch to a different server if it is better, cheaper, faster, or simply because that is the server for which a particular customer already has a site license.

In this command, the -r switch tells GNU Wget to recursively follow all links found on that page, so the tool will crawl the entire site.
