When I am trying to create a new publication service by adding database to the publication server it gives the following error:
"Cannot register database because it is already registered by a publication service"
I had previously installed xDB Replication Server but recently uninstalled and re-installed afresh. But the error persists despite the fact that no databases are shown in the publication/subscription server under SMR/MMR.
How can all previous subscription/publication databases be deleted?
Could you please follow the below workaround.
1) Stop both publication(pubserver) and subscription(subserver) services.
2) Drop xDB schema's i.e, _edb_replicator_pub and _edb_replicator_sub from the database.
3) Start both publication(pubserver) and subscription(subserver) services.
4) create a new publication service by adding database to the publication server.
You can refer below documents for more details.
Hope this helps you.
