    sqlplus as / sysdba error message


      Hi, I installed Oracle 11g database server today.


      When I tried to run sqlplus as / sysdba on dos. I got following erron message:



      C:\Users\AA>sqlplus as / sysdba


      SQL*Plus: Release Production


      Copyright (c) 1982, 2010, Oracle.  All rights reserved.


      Use SQL*Plus to execute SQL, PL/SQL and SQL*Plus statements.


      Usage 1: sqlplus -H | -V


          -H             Displays the SQL*Plus version and the

                         usage help.

          -V             Displays the SQL*Plus version.


      Usage 2: sqlplus [ [<option>] [{logon | /nolog}] [<start>] ]


        <option> is: [-C <version>] [-L] [-M "<options>"] [-R <level>] [-S]


          -C <version>   Sets the compatibility of affected commands to the

                         version specified by <version>.  The version has

                         the form "x.y[.z]".  For example, -C 10.2.0

          -L             Attempts to log on just once, instead of

                         reprompting on error.

          -M "<options>" Sets automatic HTML markup of output.  The options

                         have the form:

                         HTML [ON|OFF] [HEAD text] [BODY text] [TABLE text]

                         [ENTMAP {ON|OFF}] [SPOOL {ON|OFF}] [PRE[FORMAT] {ON|OFF}]

          -R <level>     Sets restricted mode to disable SQL*Plus commands

                         that interact with the file system.  The level can

                         be 1, 2 or 3.  The most restrictive is -R 3 which

                         disables all user commands interacting with the

                         file system.

          -S             Sets silent mode which suppresses the display of

                         the SQL*Plus banner, prompts, and echoing of



        <logon> is: {<username>[/<password>][@<connect_identifier>] | / }

                    [AS {SYSDBA | SYSOPER | SYSASM}] [EDITION=value]


          Specifies the database account username, password and connect

          identifier for the database connection.  Without a connect

          identifier, SQL*Plus connects to the default database.


          The AS SYSDBA, AS SYSOPER and AS SYSASM  options are database

          administration privileges.


          <connect_identifier> can be in the form of Net Service Name

          or Easy Connect.


            @[<net_service_name> | [//]Host[:Port]/<service_name>]


              <net_service_name> is a simple name for a service that resolves

              to a connect descriptor.


              Example: Connect to database using Net Service Name and the

                       database net service name is ORCL.


                 sqlplus myusername/mypassword@ORCL


              Host specifies the host name or IP address of the database

              server computer.


              Port specifies the listening port on the database server.


              <service_name> specifies the service name of the database you

              want to access.


              Example: Connect to database using Easy Connect and the

                       Service name is ORCL.


                 sqlplus myusername/mypassword@Host/ORCL


          The /NOLOG option starts SQL*Plus without connecting to a



          The EDITION specifies the value for Session Edition.



        <start> is: @<URL>|<filename>[.<ext>] [<parameter> ...]


          Runs the specified SQL*Plus script from a web server (URL) or the

          local file system (filename.ext) with specified parameters that

          will be assigned to substitution variables in the script.


      When SQL*Plus starts, and after CONNECT commands, the site profile

      (e.g. $ORACLE_HOME/sqlplus/admin/glogin.sql) and the user profile

      (e.g. login.sql in the working directory) are run.  The files may

      contain SQL*Plus commands.


      Refer to the SQL*Plus User's Guide and Reference for more information.


      How can I fix the problem?
