The CURRENT LOCALE LC_MESSAGES special register identifies the locale that is used by monitoring routines in the monreport module.
The monitoring routines use the value of CURRENT LOCALE LC_MESSAGES to determine what language the result set text output from the routines should be returned in. User-defined routines that are coded to return messages could also use the value of CURRENT LOCALE LC_MESSAGES to determine what language to use for message text.
The data type is VARCHAR(128).
The initial value of CURRENT LOCALE LC_MESSAGES is "en_US" for English (United States). The value can be changed by invoking the SET CURRENT LOCALE LC_MESSAGES statement.
