3 Way Replication with SYNC_CAPTURE (WBSSTORT = WBSZENTR = WBSSTORT2)

Question

Hi,
i have a big issue in Oracle Streams 11g (11.1.0.7) with a 3 Way replication with SYNC_CAPTURE.
My challenge is a replication just like that:
WBSSTORT <=> WBSZENTR <=> WBSSTORT2
I have to use the SYNC_CAPTURE because our Customer is using a Oracle Standard Edition.
I followed your Metalink Note: 462102.1 with one big difference in Capture Process.

conn stradmin/stradmin@WBSSTORT
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'mfr.t2',
streams_type => 'sync_capture',
streams_name => 'sync_capture',
queue_name => 'stradmin.streams_queue',
source_database => 'WBSSTORT.OPITZ_CONSULTING.INT');
END;
conn stradmin/stradmin@WBSSTORT2
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'mfr.t2',
streams_type => 'sync_capture',
streams_name => 'sync_capture',
queue_name => 'stradmin.streams_queue',
source_database => 'WBSSTORT2.OPITZ_CONSULTING.INT');
END;
conn stradmin/stradmin@WBSZENTR
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'mfr.t2',
streams_type => 'sync_capture',
streams_name => 'sync_capture',
queue_name => 'stradmin.streams_queue',
source_database => 'WBSZENTR.OPITZ_CONSULTING.INT',
include_tagged_lcr => true);
END;
After I have instantiatet the Table SCNs, I tried to insert a row in WBSZENTR, but that row is not propagated and applied to WBSSTORT or WBSSTORT2.
If I insert a row into WBSSTORT, nothing is propagated and applied on WBSZENTR or WBSSTORT2.
So my questions are:
1.     Can I build a 3 way Replication with SYNC_CAPTURE
2.     I’m not sure if the Apply Process working, because the apply_capture is set to TRUE, but in Oracle Documentation I read, the the SYNC_CAPTURE is Captureing only on Table and not from REDO
3.     How can I Build a 3 Way Replication with SYNC_CAPTURE
Many Thanx and greetings from Berlin – Germany
