In Oracle Spatial, WCS is implemented as a Java web application and can be deployed to run in WebLogic 12.1.3 or later.

The required Java version is JDK 1.8 or later.

This implementation of WCS is packaged in the Spatial Web Services sdows.ear file in the $ORACLE_HOME/md/jlib directory. For information about deploying this file, see Deploying and Configuring Spatial Web Services.

WCS implements three protocol binding extensions, KVP (HTTP GET), XML/POST (HTTP/POST), and XML/SOAP. It also uses GDAL to generate image formats supported by GDAL. A GDAL instance must be configured on the same system as the application container where Spatial Web Services is deployed. See Deploying and Configuring Spatial Web Services for GDAL installation instructions.

The SDO_WCS package inside Oracle Database contains procedures to initialize a WCS schema, publish GeoRaster objects as WCS coverages, and process WCS requests.

The following figure shows the WCS architecture.
