Connecting AEM to mongodb replica set

[Katrien1]

Has anyone tried connecting AEM 6.0 to a MongoDB replica set? I'm not sure how to specify the replica set here:

-Doak.mongo.uri=mongodb://localhost:27017

That will only connect to one specific mongodb instance. It might be due to my lack of mongodb knowledge, but any extra documentation around this installation would be great.

Thanks.

I think I found the information here:

• http://jackrabbit.apache.org/oak/docs/osgi_config.html [Section Mongo Configuration]
• http://docs.mongodb.org/manual/reference/connection-string/

Although it would still be nice if someone could give me an example here as well. Or if documentation was updated to explain how to connect to replica set.

Thanks but that post doesn't explain how to connect to a replica set. Only to an individual mongo instance. But I got it running now using hte documentation given in my earlier post.

It is mentioned on this page: http://jackrabbit.apache.org/oak/docs/osgi_config.html#Mongo_Configuration

It's essentially comma-delimited. E.g. -Doak.mongo.uri=mongodb://localhost:27017,localhost:27018
(You can certainly add more than two instances.)

The example on the above page also gives you some hints about configuring one instance as preferred for writes with the the other as preferred for reads: mongodb://db1.example.net,db2.example.com?readPreference=secondary&readPreferenceTags=dc:ny,rack:1&readPreferenceTags=dc:ny&readPreferenceTags=&w=1&wtimeoutMS=10000
