Replicating LOB columns with OGG

edited Dec 13, 2013 5:02AM in GoldenGate, Streams and Distributed Database (MOSC) 7 commentsAnswered

Hi,
   My customer is planning to use OGG to replicate data between databases. Some of the tables involved include LOB columns, and it is possible that the only update made to a given row in the table in the source database will be to the LOB column. Now, I have heard that if no column other than the LOB is updated by a transaction, that update may not be replicated by OGG, and I have also found the following statement in the 'Oracle GoldenGate 11g Troubleshooting & Tuning' course notes:
For LOBs to be captured in Oracle 8i and later versions of the Oracle Database, other columns in the row must be modified in the same transaction'.

Howdy, Stranger!
