	| Dear all,
 
 I have a database in Linux 5.3 in oracle database 10g. I Just remove oracle software (not database) after shutting down database.
 
 I installed the oracle 10g software again and tried to start the database..
 
 After mounting database...It says that .. Database must be started in upgrade mode..
 
 Then I startd database issuing the command..
 
 startup upgrade
 
 Now database has been started in upgrade mode.
 
 When I tried to connect to Database using schema name and password
 
 It returns errors like
 
 SQL> startup upgrade;
 ORACLE instance started.

 SQL> conn t24/t24
 ERROR:
