Explanation:
In online mode, you connect to a catalog on a running web server. In this mode your
permissions are applied, you can select a locale, and you can see the effects of any localization
on the catalog. You can see only those objects for which you have the appropriate permissions.
Both Presentation Services and the web server must be running for you to open catalogs in online
mode.
Use online mode when you want to make minor incremental changes or additions to the catalog,
such as changes to permissions, updates to a single object, or migration of new objects to a
production environment.
Note:
* You can open a catalog in one of two modes online or offline. Both modes can operate
against an actual production catalog, with no need for any downtime.
* Repository changes can be done in either online
or offline mode. Online mode is when BI Server
is actively reading the repository file (when a
user is logged in). Offline is when BI Server is
idle. Best practice is to develop in Offline mode.
Minor changes can be made when in online
mode.
