Cache Initialization File Basics

Cache Initialization File Basics

The contents of the cache initialization file are used to populate or update a cache.

This occurs when a cache server starts up, when a client application explicitly creates its cache, or when a client explicitly loads a new structure into an existing cache.

The initialization file can have any name, but is generally referred to as cache.xml. Both client applications and cache servers can use an optional cache.xml file to ease the initialization process.

File Contents

The contents of a declarative XML file correspond to APIs declared in the Cache.hpp and Region.hpp header files. The cache initialization file allows you to accomplish declaratively many of the cache management activities that you can program through the API.

  • The contents of the cache initialization file must conform to the XML definition in productDir/dtd/gfcpp-cache8000.dtd (see Native Client Cache XML DTD).
  • The name of the declarative XML file is specified when establishing a connection to the distributed system. You can define it by setting the cache-xml-file configuration attribute in the file for the native client. For details about the file, see Setting System and Cache Properties.
