Hi,
I don’t know why my Couchbase DB went to Offline. I need a reason, why it goes to Offline.
How to bringing a DB online.
I got reference link here
The API documentation for the _online call is available here:
http://developer.couchbase.com/documentation/mobile/1.2/develop/references/sync-gateway/admin-rest-api/database-admin/post-db-online/index.html
As to why it went offline - the most common cause is that Sync Gateway lost it’s connection to the backing bucket (specifically, the mutation feed for that bucket), and wasn’t able to successfully reconnect after several minutes. At that point the database is taken to an offline state, as it’s not able to serve replication requests properly.
