For messages, U.S. English is installed as the default language in the Cluster Edition. The following rules apply to language modules:
During the Cluster Edition installation or reconfiguration, you can specify a default language other than U.S. English. However, you must have installed the language module for the language you specify.
If your clients require the Cluster Edition messages in a language other than U.S. English, you must load the language module for those languages. Then, you can configure the Cluster Edition to the language used by your clients.
If the Cluster Edition does not support messages in a client’s language, these clients receive messages in the server default language.
For example, if your client’s language is Latin, the Spanish language module is installed, and Spanish is specified as the Cluster Edition default language, the client receives messages in Spanish.
