Granting role to user error

Question

Oracle 10.2.05
Linux environment
I just granted a role to a user, but the user does not have privileges base on the role.
Here is what I did:
First create a user (db_user) using system id
Second, create role schema_admin_role
Then run the script to grant privileges to the role
(SELECT 'grant select, insert, update, delete on ' ||owner|| '.'||table_name || ' to schema_admin_role;' from dba_tables WHERE OWNER = 'another_schema';
Then run
grant schema_admin_role to db_user;
The problem:
When db_user tries to update table X own by another_schema, he gets not sufficent privileges
But when I run (select owner, table_name,privilege from dba_tab_privs where grantee = 'SCHEMA_ADMIN_ROLE'; ), I see all the privileges owned by this role.
Any solution from your end will be appreciated.

did db_user start a new session after GRANT was issued?Yes he did - also when I try to list all privileges granted to db_user, I get no row seleted. On the other hand, when I query privileges granted to role schema_admin_role, I see all privileges granted earlier
example
select owner, table_name,privilege from dba_tab_privs where grantee = 'SCHEMA_ADMIN_ROLE'; ---Here we get all privileges
select owner, table_name,privilege from dba_tab_privs where grantee = 'DB_USER'; --No row seleted
