    This error usually means that the charachter set you are refereing to does not exist on the system.

    what was the charachter set before you tried to change it ? and waht did you want to change it to ?

    I f you are using a charachter set other than the default US7ASCII, you have to set the following partamters depending on your operatins sytem and database version:

    RDBMS 7.2.x -> ORA_NLS
    RDBMS 7.3.x -> ORA_NLS32
    RDBMS 8.0.x -> ORA_NLS33
    RDBMS 8.1.x -> ORA_NLS33

    This parameter should
    point to your $ORACLE_HOME/ocommon/nls/admin/data directory.

    What is the Oracle version? If < Oracle8i, then once the database is created, the character set cannot be easilly changed without recreating the database.
