If a table is reorganized using Live Reorg, it will change the object id of the table. For this reason, one cannot reorganize a source table in a replicating environment.
Using Live Reorg on secondary in a HA environment requires some considerations.
For the procedure listed below, it is assumed that you would like to reorg the table on the source:
1. Stop user access on source.
2.copy the config file, Remove the tables to be reorged from the activation file and activate the new config.
3. Reorg object(s) on this database.
4. Once reorg is completed, activate original config.
5. Once activation is completed, start post.
So as you can see, you may need downtime on the database where you are doing the reorg. You cannot reorg a table on the source side in a replicating environment unless you take the table out of replication, reorg it and then bring it back into replication.
