The repository which is sitting in the BI Server is called as
online repository. Theserve is up.All the components are connection
(Presentation Server, BI Server).When there are any changes to
repository, no need to restart the services.(Because already the BI
server is reading)
Offline Mode:
No connection to the BI Server and to the repository. The server
is down in offlinedown.When there are any changes made in
repository then we need to restart theservices because the BI
server is not connected. We must restart the services.
Differences
-To open the rpd in Online mode the server should be up and
running. To open rpdin offline mode the server should be down.-In
online mode we cant see the RPD name in the headline. In offline
mode we cansee the RPD name on the top headline.-Check in changes
icon highlighted in online mode, no need to save the rpd. Inoffline
mode it will not displayed so we need to save the repository
whenever therewere changes made.[Check in changes The changes will
be reflected to all the relative services]-Cache is enabled in
online mode; it is disabled in offline mode. Because cache willcome
only when the server is up.-Small changes in RPD can do in online
mode because the buffer size of Onlinemode is 256 KB only. Major
changes in RPD should do in Offline mode.-In online we can open
only one rpd, because server read only one rpd at a time. Inoffline
mode we can open more than one rpd.-If we open rpd in offline mode
we will have choices to open an rpd, but in onlinemode it directly
open the rpd which is in server (available in nqsconfig file).
