OBIEE: Call SAPurgeAllCache() Just a note to myself on how to clear the entire BI Server cache.

Mr. Minkjan has a great article here and Gerard Nico has one here.

Caching has been enabled (via <BI_SERVER_HOME>\server\Config\NQSConfig.ini)

For a list of ODBC Function extensions, read here.

First up, I run a simple report and then verify that there is an entry in the cache



I then create a small SQL script and put it in my c:\ folder:



(OK, just ignore what it says in the Title bar, I moved it)

Open up a cmd prompt and issue the following:

nqcmd -d AnalyticsWeb -u Administrator -p Administrator -s purgeallcache.sql

Hit enter and you should see the following:
