Hi people,
I have create a public synonym for other users object as,

Synonym created.

SQL> create view vpdep as select * from pdep;
create view vpdep as select * from pdep
ERROR at line 1:
ORA-01031: insufficient privileges
I have privilege to create view.also i can create view on a public synonym of my own objects.for ex,

Hi vidusnat!
This is from Oracle's onlinedocumentation:
>
Privileges Required to Create Views
To create a view, you must meet the following requirements:
You must have been granted one of the following system privileges, either explicitly or through a role:
o The CREATE VIEW system privilege (to create a view in your schema)
o The CREATE ANY VIEW system privilege (to create a view in another user's schema)
You must have been explicitly granted one of the following privileges:
o The SELECT, INSERT, UPDATE, or DELETE object privileges on all base objects underlying the view
o The SELECT ANY TABLE, INSERT ANY TABLE, UPDATE ANY TABLE, or DELETE ANY TABLE system privileges
In addition, in order to grant other users access to your view, you must have received object privileges to the base objects with the GRANT OPTION clause or appropriate system privileges with the ADMIN OPTION clause. If you have not, then grantees cannot access your view.

I hope that this will bring a little light into darkness!
