There is much simpler and
graceful way to shut down SSRS site while doing upgrade to avoid the problem of
people accessing site in the middle of a content update.
Basically, if you place file with
name ‘app_offline.htm’ with below contents in the root of
a web application directory, ASP.NET will shut-down the application, and stop
processing any new incoming requests for that application.
SSRS has two web sites: Report
Manager and Report Server. This means that the “app_offline.htm" web
page has to be deployed to both web sites in order to bring the SSRS web site
down for maintenance.
ASP.NET will also then respond to
all requests for dynamic pages in the application by sending back the content
of the app_offline.htm file (for example: you might want to have a “site under
construction” or “down for maintenance” message).
Then after upgrade, just
rename/delete app_offline.htm file…and the site would be back to normal.
Just remember that the size of
the file should be greater than 512 bytes, doesn’t matter even if you add some
comments to it to push the byte size as long as it’s of the size greater than
512 - it’ll work fine.
