Re: RunCommand fsync using C# driver

[craiggwilson]

Are you using authentication?  You only need to use credentials if using authentication...  

The admin database is simply a database called "admin".

   var adminDatabase = server.GetDatabase("admin");

May I ask why you need to flush to disk immediately?  What is your use case for this particular operation?

Hello,

I am developing an application using .Net 4.0 that uses Mongo as DB storage. What I am trying to do is flush all the data the the disk when the user does a certain operation. I found this thread:

https://jira.mongodb.org/browse/CSHARP-298

I was wondering how do I connect to the AdminDatabase? Is the AdminDatabase my database with MongoCredentials("admin","")?

Best regards,

Silviu.

The fsync command must be sent to the admin database.

Simply use "admin" as the parameter to GetDatabase.

And the code that generated the error:

 MongoDatabase database = MongoServer.GetDatabase(databaseName);

                if (database != null)

                {

                    var fsync = new CommandDocument { { "fsync", 1 } };//, { "async", 1 } };

                    database.RunCommand(fsync); -> error thrown here

Hello,

Thank you very much. It seems to have fixed my problem. Now fsync works.

I been meaning to ask: How do I close mongo process from C#, without Process.Kill? Server.Shutdown() throws exceptions (something was reading beyond the end of the stream).

Best regards,

Silviu.

[craiggwilson]

Server.Shutdown() is the correct method.  It will throw an error because it is looking for a response, but the server has shutdown, so no response will be given.  You just need to catch the exception as it is expected.

Hello Craig,

Thank you for clearing this up also.

Have a nice day/morning,
