Enabling and Disabling Database Options

28 CommentsOracle, ,

When you select the “Enterprise Edition” option during Oracle installation, all the components which are licensed under “Enterprise Edition” get installed by default. The idea is to install all these options and then disable those options that were not licensed.

If you need additional functionality such as partitioning some time after the initial installation, you can enable (or disable) the specific component functionality at the binary level:

1. Shutdown all database instance(s)/service(s) running from the Oracle Database Home
2. Run the following relink command to disable the option at the binary level:

Here is the list of database options and switches:

Database Option ON OFF
Data Mining dm_on dm_off
Data Mining Scoring Engine dmse_on dmse_off
Database Vault dv_on dv_off
Label Security lbac_on lbac_off
Partitioning part_on part_off
Real Application Clusters rac_on rac_off
Spatial sdo_on sdo_off
Real Application Testing rat_on rat_off
OLAP olap_on olap_off
Automatic Storage Management asm_on asm_off
Context Management Text ctx_on ctx_off

3. Startup the instance and check if the option is enabled:

      Hi İlyas,

      If you do not want to relink (as explained in the article), you need to drop Spatial objects/indexes and the Spatial user (MDSYS) to remove Spatial Option. Please check Metalink/MOS ID 179472.1 (and 273573.1)

    Hi Gokhan,
    First of all thanks for sharing your knowledge – excellent job, I really appreciate it!

    Do you know is there also an easy way to disable Active Data Guard option in 11g which comes by default while using OUI ?

    How can we enable partitioning option on Oracle 11g express windows 32 version?

    • Gokhan Atil

      Lal,

      XE edition does not support partitioning, so you can not enable it.

    How can u remove the DB objects/schema for these option if installed via OUI/

      Hi Rishi,

      It depends on which option you disable. You should search My Oracle Support documents to remove related DB objects (if there’s any). For example if you disable OLAP and find invalid OLAP Objects in SYS And OLAPSYS Schemas, you need to follow the instructions in Doc ID 565773.1 to remove the objects.

    How can I enable data mining after I installed the Oracle 11g R2 XE?

    • Gokhan Atil

      Hi Ruthira,

      Oracle Data Mining features is not included with Oracle Database XE, so you can’t enable it.

    How does one turn off Advanced Compression? Many post mention Parameter _oltp_compression. However, that Parameter doesn’t work, see my Little test below:

    SQL> alter system set “_oltp_compression”=false;

    System altered.

    SQL> show parameter oltp

    NAME TYPE VALUE
    ———————————— ——————————— ——————————
    _oltp_compression boolean FALSE

    SQL> create table test (kol1 varchar2(10));

    Table created.

    SQL> alter table test compress for oltp;

    Table altered.

    SQL> select table_name, compress_for from dba_tables where table_name like ‘TEST’;

    TABLE_NAME COMPRESS_FOR
    ———————
    TEST ADVANCED

      Hi Rob,

      As I know, it’s not possible to disable or uninstall Advanced Compression. I made a quick search on My Oracle Support and found the following document:

      Can The Advanced Compression Option (ACO) Be Disabled Or Uninstalled? (Doc ID 1459216.1),

      It says there’s no way 🙂

    Hi Gokhan,

    We have selected Large database option while installing which partitioning the SOAINFRA tablespace however due to some purge issue we want to disable the partitioning for which we would follow you steps given above however what to do with the existing SOAINFRA tablespace partitions.

    We have a activity scheduled to purge the tablespace by dropping the old partition and exp/imp the data to reclaim the space at the OS level, if you can help us on what can be done with the existing partition we can perform those steps in the next outage.

    Hi Gokhan,

    12c dbca in silent mode not excluding unwanted components(example Oracle Spatial,Oracle Text, Oracle Label Security,Oracle Database Vault etc). How we can avoid to get installed during database creation using dbca as we don’t have License for these components.

    I have tried to get it excluded on template which I have created, but still it getting installed.

    Regards,
    Hari

    Hello Gokhan,

    I am kinda confused here. the Oracle partition parameter value is ‘TRUE’

    from SELECT * FROM V$OPTION WHERE PARAMETER = ‘Partitioning’;

    Do i still need a license for using it or i can go ahead and start partitioning my pretty large tables.

    • Gokhan Atil

      Yes, you need to buy required licenses to use it. Oracle usually provide their software without any “software protection” or limitation, but it doesn’t mean that it’s a free software 🙂

    In v$option, it shows ‘Ture’ for some oracle DB options. How can we disable one optional feature in DB?

    After we disable already enabled partitioning.

    What happens\what is affected?

    • Gokhan Atil

      Partitioned tables remain “partitioned” but you can not create a new partitioned table or index.
