Propagation not working. Basic Question.

Question

Hi,
I was trying to setup Replication between 2 Oracle 10g Enterprise Editions installed on 2 different machines using Oracle Streams. While Installing the 2 databases I created the first database with the name source and the other with name target.
global_names is set to true:
alter system set global_names=true;
Created the user strmadmin in both the databases and created the tables EMP_SOURCE in the source database and EMP_TARGET in target database.
Setup the links as below:
CREATE DATABASE LINK target CONNECT TO strmadmin IDENTIFIED BY strmadmin USING *'target'*;
CREATE DATABASE LINK source CONNECT TO strmadmin IDENTIFIED BY strmadmin USING *'source'*;
Tested that the DB Links works in both the databases giving results back.
select * from strmadmin.EMP_SOURCE@source;
select * from strmadmin.EMP_TARGET@target;
select * from [email protected]
select * from [email protected]
I then go to setup the capture, propogation and apply process. The capture and apply process seem ok however the propogation process is throwing the error as below:
Propagation Process:
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_PROPAGATION_RULES(
table_name => 'strmadmin.EMP_SOURCE',
streams_name => 'strm01_propagation',
source_queue_name => 'strmadmin.source_queue',
destination_queue_name => *'strmadmin.target_queue@target'*,
include_dml => true,
include_ddl => true,
source_database => *'source'*,
inclusion_rule => true,
queue_to_queue => true);
END;
Error thrown:
Propagation Schedule for (STRMADMIN.SOURCE_QUEUE, "STRMADMIN"."TARGET_QUEUE"@TARGET.REGRESS.RDBMS.DEV.US.ORACLE.COM) encountered following error:~ORA-04052: error occurred when looking up remote object [email protected]~ORA-00604: error occurred at recursive SQL level 4~ORA-12154: TNS:could not resolve the connect identifier specified~ORA-06512: at "SYS.DBMS_AQADM_SYS", line 1087~ORA-06512: at "SYS.DBMS_AQADM_SYS", line 7616~ORA-06512: at "SYS.DBMS_AQADM", line 631~ORA-06512: at line 1~Propagation Schedule for (STRMADMIN.SOURCE_QUEUE, "STRMADMIN"."TARGET_QUEUE"@TARGET.REGRESS.RDBMS.DEV.US.ORACLE.COM) disabled due to 16 consecutive errors.
Any pointers will be greatly appreciated.
PS: I am new to Oracle Streams and DBA and need to accomplish this quickly so please forgive my ignorance.
Do let me know if you need any other information.
Warm Regards,

Answer 1

global name means that dblink_name=db_global_name so:
CREATE DATABASE LINK target.REGRESS.RDBMS.DEV.US.ORACLE.COM CONNECT TO strmadmin IDENTIFIED BY strmadmin USING 'target.REGRESS.RDBMS.DEV.US.ORACLE.COM';
CREATE DATABASE LINK source.REGRESS.RDBMS.DEV.US.ORACLE.COM CONNECT TO strmadmin IDENTIFIED BY strmadmin USING 'source.REGRESS.RDBMS.DEV.US.ORACLE.COM'';
and...
destination_queue_name => 'strmadmin.target_queue@target',
source_database => 'source',
replace
destination_queue_name => '[email protected]',
source_database => null,
or
destination_queue_name => '[email protected]',
source_database => 'source.REGRESS.RDBMS.DEV.US.ORACLE.COM',
