List and test enabled OracleDB features using the commandline

While automating the deployment and configuration of Oracle 12c installations, I've had a need to be able to detect and automatically disable certain features which require extra licensing fees.

Some of these extra features graciously enabled by default by Oracle are:

• Real Application Testing (rat)
• Partitioning (partitioning)
• On-line Analytical Processing (olap)
• Data Mining (dm)

One way of checking if these options are enabled is by connecting to the database and see if those are listed in the banner:

oracle@hostname:~> sqlplus / as sysdba

SQL*Plus: Release 12.1.0.2.0 Production on Tue Jul 14 0:47:15 2015
Copyright (c) 1982, 2014, Oracle. All rights reserved.

Connected to:

Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production

With the Partitioning, Automatic Storage Management, OLAP, Advanced Analytics and Real Application Testing options

Unfortunately it's not easy or reliable to parse that output.

One way which I've found to get a proper listing was to use sqlplus (Note: in the examples it's implied that you have an ORACLE_SID set containing the name of the database needed).

oracle@hosname:~> sqlplus -L / as sysdba <<< 'select * from v$option;'

...
SQL> 
PARAMETER
----------------------------------------------------------------
VALUE								     CON_ID
--------------------------------------------------------------------------
Partitioning
FALSE									  0

Objects
TRUE									  0

Real Application Clusters
FALSE									  0


PARAMETER
----------------------------------------------------------------
VALUE								     CON_ID
--------------------------------------------------------------------------
Advanced replication
TRUE									  0

Bit-mapped indexes
TRUE									  0

Connection multiplexing
TRUE									  0

...

This is a bit better, though it needs some work to properly parse.

oracle@hostname:~> sqlplus -L / as sysdba <<< 'select * from v$option;' | grep -A 1 '^Real Application Testing$' | grep TRUE

oracle@hostname:~> sqlplus -L / as sysdba <<< 'select * from v$option;' | grep -A 1 '^Partitioning$' | grep TRUE

oracle@hostname:~> sqlplus -L / as sysdba <<< 'select * from v$option;' | grep -A 1 '^OLAP$' | grep TRUE

oracle@hostname:~> sqlplus -L / as sysdba <<< 'select * from v$option;' | grep -A 1 '^Data Mining$' | grep TRUE

These commands can be used to provide the correct return code to indicate if any of the above listed features are enabled in a script.

To disable these features, you will need to shutdown every database running in the current oracle home and afterwards restart it.
This can also be done with the following commands:

oracle@hostname:~> sqlplus -L / as sysdba <<< 'shutdown immediate'

oracle@hostname:~> chopt disable rat
oracle@hostname:~> chopt disable olap
oracle@hostname:~> chopt disable partitioning
oracle@hostname:~> chopt disable dm

oracle@hostname:~> sqlplus -L / as sysdba <<< 'startup'
