Replicate in Source fails with ORA-01403

Question

Hi,
I've set up a bidirectional replication between two Oracle 11g R2 databases (WIN11SRC and WIN11TRG). Initially, the data was consistent between the two databases.
Now, when I update a record in the source, I find it successfully got replicated in the target.
But when I update a record in the target, it doesn't get through to the source. It fails in the source and rejected by its Replicate. The discard file shows the following error when I tried to update the Department_Name column:
OCI Error ORA-01403: no data found, SQL
<UPDATE "HR"."DEPARTMENTS" SET "DEPARTMENT_NAME" = :a1,"DML_TIMESTAMP" = :a2
WHERE "DEPARTMENT_ID" = :b0 AND "DEPARTMENT_NAME" = :b1 AND "DML_TIMESTAMP" = :b2>
Operation failed at seqno 3 rba 1740
Discarding record on action DISCARD on error 1403
Problem replicating HR.DEPARTMENTS to HR.DEPARTMENTS
Record not found
Mapping problem with compressed update record (target format)...
DEPARTMENT_ID =
DEPARTMENT_NAME = Administration7
DML_TIMESTAMP = 2012-08-16 09:30:04.068000000
*In the source, I've got the following pararmeter files set up:

/I'm working on GG version 11g R2.
Thanks in advance.

Answer 1

You forgot to "ADD TRANDATA" (add PK logging) on the target. You did it on the source but just forgot to do it on the target. Here's how I know:
1. It s 1403 - no data found. Usually a supplemental log issue.
2. Discards shows:
DEPARTMENT_ID =
I assume that this would be all or part of a PK. No data, not supplemental logging..
Good luck,
