Hi Olivier,

Could you provide more information about what you are trying to achieve and where did you find a recommendation to set EnableWriteMajority=true?

Currently as of MongoDB 3.2.9, there is no such parameter for mongod as EnableWriteMajority. You can set w : majority as Write Concern on the client side, either in Mongo Shell or on a MongoDB Driver. Please keep in mind that different clients can use different write concerns as needed without changing configuration on mongod, therefore, it’s a client operation parameter rather than a server parameter.

For example, using Mongo Shell, you could specify:

db.collection.insert( {a : 1}, {w : 'majority'} )

You can check the relevant MongoDB Driver Documentation. Here is an example from the Java Driver.

Regards,

Amar
