  • Clusters define a collection of servers that operate as if they were a single machine. The primary purpose of high availability (HA) clusters is to provide uninterrupted access to data, even if a server loses network or storage connectivity, or fails completely, or if the application running on the server fails. HA clusters are mainly used for e-mail and database servers, and for file sharing. In their most basic implementation, HA clusters consist of two server machines (referred to as “nodes”) that “share” common storage.

  • Spatial database management deals with the storage, indexing, and querying of data with spatial features, such as location and geometric extent. The field emerged from Geographic Information Systems (GIS) and Computer Aided Design (CAD) applications, from which it became apparent that there is a need for the efficient management of large-scale spatial data. More recently, Location Based Services (LBS) brought spatial data management needs to common users, who routinely run spatial queries on their computers or mobile devices.

  • Tablespaces and Data Files Databases, tablespaces, and data files are closely related, but they have important differences: An Oracle database consists of one or more logical storage units called tablespaces, which collectively store all of the database’s data. Each tablespace in an Oracle database consists of one or more files called data files, which are physical structures that conform with the operating system in which Oracle is running. A database’s data is collectively stored in the data files that constitute each tablespace of the database.

  • Types of Segments Segments are space-occupying objects in a database. They use space in the data files of a database. This section describes the different types of segments. Table A table is the most common means of storing data within a database. A table segment stores that data for a table that is neither clustered nor partitioned. Data within a table segment is stored in no particular order, and the database administrator (DBA) has very little control over the location of rows within the blocks in a table. All the data in a table segment must be stored in one tablespace.
