After you have added a subscription database definition you will find a single table named rrep_txset_health has been created as the subscription metadata object.
For Oracle only: The RREP_TXSET_HEALTH table is created in the subscription database user’s schema as shown in the following output:
For SQL Server only: The rrep_txset_health table is created in the schema named _edb_replicator_sub.
For Postgres only: The rrep_txset_health table is created in the schema named _edb_replicator_sub.
In all subscription database types (Oracle, SQL Server, and Postgres) when you remove the subscription database definitions using the xDB Replication Console or xDB Replication Server CLI, the subscription metadata object is deleted from the subscription database.
