Advanced Analytics                       TRUE                 0

User wants to disable this option from database.

The Solution

In Oracle 12c, Oracle Advanced Analytics is a combination of Oracle Data Mining and Oracle R Enterprise.

Verify Oracle Data Mining and Oracle R installed in your database

A. Verify Data Mining option is installed in your database

SQL> select * from v$option where PARAMETER like '%Data Mining%'

PARAMETER VALUE CON_ID
-------------------- -------------------- ----------
Data Mining TRUE 0

B. Verify Oracle R is installed in your database

To verify R installation, just run R in command line. This command will open R command prompt

$ R
Oracle Distribution of R version [Oracle R Version]

...(output truncated)

> q()
Save workspace image? [y/n/c]: n

Another method to check if R is installed is to check its version using the below command.

$ R --version
Oracle Distribution of R version 3.3.0 (--) -- "Supposedly Educational"

Disable Oracle Data Mining and Oracle R from database

A. Disable oracle Data Mining option

Steps for RAC Database :

$ cd $ORACLE_HOME/bin
$ srvctl stop database -d [SID]
$ chopt disable dm
$ srvctl start database -d [SID]

Steps for non-RAC Database:

$ cd $ORACLE_HOME/bin
$ sqlplus / as sysdba
sql> shut immediate;
sql> exit
$ chopt disable dm
$ sqlplus / as sysdba
sql> startup;

B. Uninstall Oracle R

A full uninstall removes the rqsys metadata and PL/SQL code from the database and removes all Oracle R Enterprise Server libraries and R packages from Oracle home.

./server.sh --uninstall --full
./server.sh -u -full

Verification

Use the below query to verify that the Advanced Analytics is disabled from the Oracle Database 12c:

SQL> select * from v$option where PARAMETER like '%Advanced Analytics%';

PARAMETER                                VALUE                CON_ID
---------------------------------------- -------------------- ----------
Advanced Analytics                       FALSE                0
