B Oracle Locator

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 and Enterprise Editions of Oracle Database 11g 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.

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:

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 requires 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.

Multimaster replication of SDO_GEOMETRY objects

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.
