// * Cause: Either an attempt was made to issue an alter session command
// With an invalid NLS parameter or value; or the environment
// Variable (s) NLS_LANG, ORA_NLSxx, or ORACLE_HOME was incorrectly
// Specified, therefore the NLS data files cannot be located.
// * Action: Check the syntax of the alter session command and the NLS
// Parameter, correct the syntax and retry the statement, or
// Specify the correct directory path/values in the environment
// Variables.
