Oracle Locator (also referred to as Locator) is a feature of Oracle Database 11g Standard Edition. Locator provides core features and services available in Oracle Spatial. It provides significant capabilities typically required to support Internet and wireless service-based applications and partner-based GIS solutions. Locator is not designed to be a solution for geographic information system (GIS) applications requiring complex spatial data management. If you need capabilities such as linear referencing, advanced spatial functions, or Spatial Web services, use Oracle Spatial instead of Locator.
Like Spatial, Locator is not designed to be an end-user application, but is a set of spatial capabilities for application developers.
Locator is available with the Standard Edition One, Standard Edition, and Enterprise Edition of Oracle Database, and with Oracle Database XE (Express Edition). Spatial is a priced option available only with Oracle Database 11g Enterprise Edition. Spatial includes all Locator features as well as other features that are not available with Locator.
If you want to ensure that you are using only features available in Locator, see Section B.1, "Installing and Deinstalling Locator or Spatial Manually". For licensing information about Spatial and Locator, see Oracle Database Licensing Information.
The installation of Locator depends on the successful and proper installation of Oracle Multimedia. Oracle Multimedia is installed and configured with Oracle Database 11g, although you can install Oracle Multimedia manually if necessary, as documented in Oracle Multimedia User's Guide. During the installation of Oracle Multimedia, Locator is installed.
In general, Locator includes the data types, operators, and indexing capabilities of Oracle Spatial, along with a limited set of the subprograms (functions and procedures) of Spatial. The Locator features include the following:
An object type (SDO_GEOMETRY) that describes and supports any type of geometry
A spatial indexing capability that lets you create spatial indexes on geometry data
Spatial operators (described in Chapter 19) that use the spatial index for performing spatial queries
Most geometry functions and spatial aggregate functions (as explained in Table B-1)
Coordinate system support for geometry and layer transformations (SDO_CS.TRANSFORM function and SDO_CS.TRANSFORM_LAYER procedure, described in Chapter 21)
Tuning subprograms (SDO_TUNE package, described in Chapter 31)
Spatial utility functions (SDO_UTIL package, described in Chapter 32)
Classes in the oracle.spatial.geometry (sdoapi.jar) and oracle.spatial.util (sdoutil.jar) packages of the Spatial Java API (described in Oracle Spatial Java API Reference)
For information about spatial concepts, the SDO_GEOMETRY object type, support for SQL Multimedia types annotation text, and indexing and loading of spatial data, see Chapters 1 through 5 in this guide. For reference and usage information about features supported by Locator, see the chapter or section listed in Table B-1.

Although Locator is available on both the Standard and Enterprise Editions of Oracle Database 11g, some Locator features require database features that are not available or are limited on the Standard Edition. Some of those Locator features and their availability are listed in Table B-3.
Table B-3 Feature Availability with Standard or Enterprise Edition
| Feature | Standard/Enterprise Edition Availability |
|---|---|
|
Parallel spatial index builds |
Supported with Enterprise Edition only. |
|
Supported with Enterprise Edition only. (Single master/materialized view replication for SDO_GEOMETRY objects is supported with both Standard Edition and Enterprise Edition. See Oracle Database Advanced Replication for more information.) |
|
|
Partitioned spatial indexes |
Requires the Partitioning Option with Enterprise Edition. Not supported with Standard Edition. |
To install Spatial or to use any features that are specific to Spatial but not Locator, you must meet the licensing requirements for Spatial. For licensing information about Spatial and Locator, see Oracle Database Licensing Information.
Scripts are available to perform certain installation and deinstallation operations relating to Locator and Spatial:
mddins.sql manually deinstalls Spatial and leaves only Locator, thus "installing" only Locator. This ensures that you can use only features available in Locator and no features that are available only with Spatial.
mdinst.sql manually installs Spatial, so that you are able to use all features available with Spatial and Locator.
If you want to ensure that you are using only Locator features, but Spatial is already installed, run the mddins.sql script, as follows:
Ensure that Oracle Multimedia is installed.
Connect to the database as the SYS user with SYSDBA privileges (SYS AS SYSDBA, and enter the SYS account password when prompted).
Start SQL*Plus, and enter the following statement:
Linux: @$ORACLE_HOME/md/admin/mddins.sql
Windows: @%ORACLE_HOME%\md\admin\mddins.sql
If you need to be able to use Spatial, you can run the mdinst.sql script, as follows:
Connect to the database as the SYS user with SYSDBA privileges (SYS AS SYSDBA, and enter the SYS account password when prompted).
Start SQL*Plus, and enter the following statement:
Linux: @$ORACLE_HOME/md/admin/mdinst.sql
Windows: @%ORACLE_HOME%\md\admin\mdinst.sql
