Each server instance, including the Administration Server, has a default persistent store that requires no configuration. The default store is a file-based store that maintains its data in a group of files in a server instance data\store\default directory. A directory for the default store is automatically created if one does not already exist.

This default store is available to subsystems that do not require explicit selection of a particular store and function best by using the system's default storage mechanism. For example, a JMS Server with no persistent store configured will use the default store for its Managed Server and will support persistent messaging.

The default store can be configured by directly manipulating DefaultFileStoreMBean parameters. If this MBean is not defined in the domain configuration file, then the configuration subsystem ensures that the DefaultFileStoreMBean always exists with the default values.

The default store maintains its data in a data\store\default directory inside the servername subdirectory of a domain's root directory.

For example, if no directory name is specified for the default file store, it defaults to:

ORACLE_HOME\user_projects\domains\domain-name\servers\server-name\data\store\default

where domainname is the root directory of your domain, typically c:\oracle\user_projects\domains\domainname, which is parallel to the directory in which WebLogic Server program files are stored, typically c:\oracle\wlserver_12.1.

This section provides an example of how a default file store may look in a domain's configuration file, with the default directory location and Synchronous Write Policy settings overridden.

<server
  <name>myserver</name>
  <default-file-store>
  <directory>C:/store</directory>
  </default-file-store>
</server>
