Re: Streams configuration within schemas in a database

   Since you have streams running already, I assume, you know how to do basic setup for streams. With that, to setup streams between two schemas in the same database, you would setup streams just like schemas between two different database (i.e. loop back database link, capture, propagate and apply) etc. Then add a DML handler to the table at apply process.

  Please see example code below. Of course, I haven't tested this, but should work just fine.

  Example: EMP table from SCOTT schema to MARY schema. REM
REM We create a generic dml handler so that we can reuse it. REM Following example manipulates LCRs and updates schema. REM conn as strmadmin for this procedure CREATE OR REPLACE PROCEDURE generic_dml_handler(in_any IN SYS.ANYDATA) IS lcr SYS.LCR$_ROW_RECORD;
rc PLS_INTEGER;
command VARCHAR2(10);
old_values SYS.LCR$_ROW_LIST;
l_object_name varchar2(31);
BEGIN
-- Access the LCR
rc := in_any.GETOBJECT(lcr);
-- Get the object command type
command := lcr.GET_COMMAND_TYPE();
-- Get current object name
l_object_name := lcr.GET_OBJECT_NAME();
-- Set the object_owner in the row LCR if object name and owner matches. if (l_object_name='EMP') then

   l_owner := lcr.GET_OBJECT_OWNER();
   IF (l_owner = 'SCOTT') then

• Schema owner modified from scott to mary for emp table. lcr.SET_OBJECT_OWNER ( 'MARY'); end if; end if; -- Apply the row LCR as an INSERT into the new table lcr.EXECUTE(true); END; / REM Add above DML Handler to the table

BEGIN
DBMS_APPLY_ADM.SET_DML_HANDLER(
object_name => 'scott.emp',
object_type => 'TABLE',
operation_name => 'INSERT',-- modify accordingly error_handler => false,
user_procedure => 'strmadmin.generic_dml_handler', apply_database_link => NULL);
END;
/
