I want to copy all the objects of Scott schema to another schema.
I can not understand what the code should be. Like bellow one?
create user scott1 identified by tiger1;
It's a quite old database. Your SQL command creates new user.
You can use Export in order to copy contents of one schema to another.
exp FILE=$ORACLE_HOME/scott_export.dmp LOG= $ORACLE_HOME/scott_export.log OWNER=scott
Create new user as you have shown in your post and grant required privileges. Then import it to new schema.
imp FILE=$ORACLE_HOME/ scott_export.dmp LOG= $ORACLE_HOME/scott_import.log FROMUSER=scott TOUSER=scott2
