If a parameter value contains a special character, then the special character must be preceded by a backslash or the entire parameter value must be enclosed in quotation marks. For example, you can specify special characters using either of the following:
DB_DOMAIN = 'JAPAN.ACME#.COM' DB_DOMAIN = JAPAN.ACME\#.COM
Table 1-1 lists the special characters you can use in initialization parameter files.
