Let Capture build the transaction message with non-LOB columns first and LOB columns last instead of in strict column sequence order.

Please consider changing Capture to build transaction messages with all non-LOB data first, then add on the LOB data after all other non-LOB data no matter what the sequence numbers. This would prevent the risk of splitting a message on non-LOB da...

To support the creation of a Db2 range-partitioned target table if the source table is a Db2 range-partitioned table and the target table does not exist when creating a Q Subscription.

According to the current design, when the target table does not exist, Q Replication can automatically create the target table based on the source table schema when creating a Q Subscription. However, Q Replication always creates a normal table, r...
