In the tree component, expand the StandAlone instance and select the server instance node.
Select the Advanced tab.
On the Domain Attributes page, you may do the following:
In the Application Root field, identify the full directory path where the applications will be deployed.
In the Log Root field, specify where the server instance log files are kept.
Typically, you will leave the Locale field blank to use the default locale of the host.
A locale is an identifier that specifies a particular combination of language and region. For example, the locale for American English is en_US, and for Japanese it is ja_JP. In order to use a non-English locale, the Application Server must be localized, a process that includes translating English into another language.
Restart the server.
