Replication issues

[Media Lab]

We have 2 servers with Raven on them. Both have licenses for replication.

On server 1, we have a table - ApiLogging with replication enabled and a destination to server 2 and vice versa on server 2.

We use API keys for this, and each server has the other server's correct replication key that's marked for Read/Write access to *

On either server, I see this document

{

    "Destinations": [

        {

            "Url": "http://server2",

            "Username": null,

            "Password": null,

            "Domain": null,

            "ApiKey": "RavenReplication/xxxxxxxxxxxx",

            "Database": "ApiLogging",

            "TransitiveReplicationBehavior": "Replicate",

            "IgnoredClient": false,

            "Disabled": false,

            "ClientVisibleUrl": null,

            "SkipIndexReplication": false,

            "SpecifiedCollections": {}

        }

    ],

    "Source": "33d28b1c-81fd-4e43-bf77-fa0bae823b47",

    "ClientConfiguration": {}

}

and this in the confi

    "Id": "ApiLogging",

    "Settings": {

        "Raven/ActiveBundles": "DocumentExpiration,Replication",

        "Raven/DataDir": "~/ApiLogging"

    },

    "SecuredSettings": {},

    "Disabled": false

}

However, both servers complain that replication is not enabled

{

  "Error": "replication bundle not activated in database named: ApiLogging"

}

I have replication working on a FS and another DB on both boxes. I've had trouble getting replication to work so I removed all replication and started adding them back one by one. Now I'm stuck again.

As a side note, trying to get replication topology on server 1 throws a 500 error

{

  "Url": "/admin/replication/topology/global",

  "Error": "System.InvalidOperationException: Couldn't locate ReplicationTask\r\n   at Raven.Database.Bundles.Replication.Impl.ReplicationTopologyDiscoverer..ctor(DocumentDatabase database, RavenJArray from, Int32 ttl, ILog log)\r\n   at Raven.Database.Server.Controllers.Admin.AdminController.<>c__DisplayClass53_0.<CollectReplicationTopology>b__0(DocumentDatabase db)\r\n   at Raven.Database.Server.Tenancy.DatabasesLandlord.ForAllDatabases(Action`1 action, Boolean excludeSystemDatabase)\r\n   at Raven.Database.Server.Controllers.Admin.AdminController.CollectReplicationTopology()\r\n   at Raven.Database.Server.Controllers.Admin.AdminController.<GlobalReplicationTopology>d__52.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Threading.Tasks.TaskHelpersExtensions.<CastToObject>d__3`1.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ApiControllerActionInvoker.<InvokeActionAsyncCore>d__0.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ActionFilterResult.<ExecuteAsync>d__2.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ExceptionFilterResult.<ExecuteAsync>d__0.MoveNext()"

}

So something looks screwy somewhere.

What version of ravendb you are using?

[Media Lab]

35180

[Idan Haim]

Can you please send me screen image of both

databases Raven/Replication/Destinations

and make sure database replication is really enable

[Idan Haim]

For extra can you open 2 new database and test replication on them 

Thank you

The actual error indicates that the destination db doesn't have the replciation bundle setup.

It *did* though.

I deleted the DB off Server 1 (left the files) and 're added' it back and it magically started working.

The actual error is likely here:

        "Raven/ActiveBundles": "DocumentExpiration,Replication",

The seprator here is semi colon, not comma, should be:

        "Raven/ActiveBundles": "DocumentExpiration;Replication",

[Media Lab]

*facepalm*

This is why there's a HUGE RED ALERT telling you manually doing this is bad for your health.

The problem is we didn't have these bundles activated when we created the data & had to activate them afterwards.

I live in .Net. Isn't the first time a semicolon kicked my butt.

This has bitten me too, PR to support both separators? :)

Note that you can't activate the replication bundle after the creation of the database (unless you are using RavenDB 3.5)

No, this is an unsupported operation to start with.

We are, so it did work.

However, what would be the correct way to take an existing db and add a bundle? Does deleting it (leaving the files) and recreating it with the appropriate settings keep everything exactly how it was, data wise, but activates the bundle?

[Oren Eini (Ayende Rahien)]

No, that isn't supported either.

The proper way to do it is to export the data, recreate the db and import the data

[Jahmai Lay]

What? Custom bundles?

[Media Lab]

AHA! I just found out this wasn't me! 

I went to a Db that didn't have replication and used Studio to turn it on and this happened

No replication
