Database Access in Oracle 9i

Question

Hi I am new in Oracle, I am tring to understand how Oracle gives permission for users to access databases. For example if I create store database, system creating also store user, how about if I create a single user, say user1, what should I do to access store database with using user1 user?
So far I could not access even though I set some privileges for user1.
Thanks

Answer 1

In order to make things, try creating a role
Then, grant select on all tables of a particular schema to this role
Grant this role to new schema being created
Then create public synonyms for these tables.
The new schema should then be able to access the tables owned by remote user.
For example,
user SCOTT wants to access all the tables owned by user SH
create role browse_schema_role;
[Now login in as SH or SYSTEM]
grant select on SH.customers to browse_schema_role;
grant select on SH.products to browse_schema_role;
grant select on SH.sales to browse_schema_role;
etc...
[Login as SYSTEM or a user that has DBA privileges]
grant browse_schema_role to SCOTT;
create public synonym customers for SH.customer;
create public synonym products for SH.products;
create public synonym sales for SH.sales;
[Now login as SCOTT]
Now you should be able to select any table owned by SH
e.g., select * from customers;
Hope this helps.
