ORA-16000: database open for read-only access

Lets suppose we have two databases opened in Read Only mode.
1.    DB1
2.    DB2

and on DB1, we have a DBLINK on DB2 named DB2.

Now, if we try to execute following query on DB1

FROM scott.emp EMP, scott.DEPT@DB2 DEPT

it will throw following error
ORA-16000: database open for read-only access

to avoid this we must set our transaction as read only using follwoing command

set transaction read only;

  1. well, but usually we want to transfer data insert into select * from db@db2. Which is not read only.

    And this does not help when calling procedure via link:
    SELECT PA.IDDocument, PA.ValidFrom, PA.ValidTo, PA.Valid
    FROM rt_pado@schstb pa
    WHERE PA.IDPADORelationType = 1 AND
    ( RT_CLISRV_UTIL_PKG.IS_VALID@schstb(SYSDATE, PA.ValidFrom, PA.ValidTo, PA.Valid) = 'Y' )
