SQL & PL/SQL

Hi

I'm using sql developer to test this

I have a package with few procedures in it on the one of the database
when these procedures are called directly

my_support_api.create_user('Archtestdm','USERS_T_S_01','TEMP','welcome123', ret_num, ret_msg);

it works without any error

but when I call from another database via link


declare
ret_num number;
ret_msg varchar2(400);

begin



my_support_api.create_user@my_link('Archtestdm','USERS_T_S_01','TEMP','welcome123', ret_num, ret_msg);

dbms_oputput.putline(ret_msg);
end;

I get error

ORA-02064: distributed operation not supported

remote procedure does not have any commit statement.
Need assistance on this

Thanks
Archana
