Which after being given added

     (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)  
     (SID_NAME = ORCL)

Then restart the listener service
my computer - "Right -" - "attribute -" Services and Applications - "service -"
which the oracle *** TNSListener and oracleServiceORCL need to restart

After a successful connection with a database tool built table space, the user

I use this process to create a system user, as is the new oracle, login password is always set installed, try to use the database connectivity tools, do not use the built-in sqlplus, because I tried to find data in both construction is isolated, finding each other, do not know where to set up wrong
