Remote Database connection error on local database while running a procedur

Question

Dear Gurus,
I am trying to run a procedure to grant Select Access to all objects of a schema to all schema but getting below error messages:
Error report:
ORA-02019: connection description for remote database not found
This is on local database and all required privileges have been given to run this procedure but I dont understand why this error is being thrown every time. I am able to fetch all the tables directly (i.e. SELECT object_name FROM user_objects where OBJECT_TYPE IN('TABLE','VIEW','MATERIALIZED VIEW') AND STATUS='VALID')
Kindly let me know if you have any solution.
Procedure detail:
declare
sqltxt varchar(250);
cursor course_det is
SELECT object_name FROM user_objects where OBJECT_TYPE IN('TABLE','VIEW','MATERIALIZED VIEW') AND STATUS='VALID';
v_objnm user_objects.object_name%type;
begin
open course_det;
loop
fetch course_det into v_objnm;
exit when course_det%notfound;
sqltxt :='GRANT SELECT ON ' || v_objnm|| ' TO public with grant option';
EXECUTE IMMEDIATE sqltxt ;
end loop;
end;
System detail:
Oracle 11.2.0.3/Linux 5.3
Ragards.

Hi,
It seems you are fetching records from one database to other. for that you need to create dblink for that.
Create dblink first and then try to fetch records using that dblink.
ORA-02019: connection description for remote database not found
Cause: An attempt was made to connect or log in to a remote database using a connection description that could not be found.
Action: Specify an existing database link. Query the data dictionary to see all existing database links. See your operating system-specific Net8 documentation for valid connection descriptors.
