Schema Level Bidirectional streams - works only in one direction

Question

Hi All,
we are implementing bidirectional streams at schema level(using scott schema for testing).
Our environment and different parameters are:
Source:
OS =Win2003 64bit
DB Version= 10.2.0.5.0 64bit
DB SID=CIBSPROD
log_archive_dest_1 LOCATION=E:\DBFILES\ArchiveLog\CIBSPROD\PrimaryRole VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=CIBSPROD
log_archive_dest_2 SERVICE=CIBSREP LGWR ASYNC NOREGISTER VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=CIBSREP
job_queue_processes=2
Dest:
OS =Win2003 64bit
DB Version= 10.2.0.5.0 64bit
DB SID=CIBSREP
log_archive_dest_1 LOCATION=E:\DBFILES\ArchiveLog\CIBSREP\PrimaryRole VALID_FOR=(ONLINE_LOGFILE,PRIMARY_ROLE) DB_UNIQUE_NAME=CIBSREP
log_archive_dest_2 SERVICE=CIBSPROD LGWR ASYNC NOREGISTER VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=CIBSPROD
job_queue_processes=2
Follow the "Streams Bi-Directional Setup [ID 471845.1]" article
Problem we are facing is changes are propagating from Source(CIBSPROD)  to Destination(CIBSREP) BUT NOT from Destination to Source Database(although archivelogs are shipping from Destination to Source).

What we have missed in the configuration?

Answer 1

Find error SRC database "ORA-26687: no instantiation SCN provided fro SCOTT.STRMTEST in source database CIBSREP"
SCOTT.STRMTEST is heartbeat table used from streams replication on Source and Destination database
