Connecting to a MongoDB Atlas Cluster

Hi
can anyone pls help me with an example of connecting to a MongoDB Atlas cluster (their cloud service). My Atlas cluster replica set is at the urls yyyy-shard-00-00.xxxxx.mongodb.net:27017 yyyy-shard-00-01.xxxxx.mongodb.net:27017 yyyy-shard-00-02.xxxxx.mongodb.net:27017 The MongoDB Atlas website specifies the application connectstring as 'mongodb+srv://<username>:<password>@yyyy.xxxxx.mongodb.net/<mydefaultdatabase>?retryWrites=true&w=majority" I saw the doc / example on pharo-nosql/mongotalk but could not figure out in MongoClient - 1. how to get embed the username:password in the connectstring which i feel would be needed, 2. how to specify the default database 3. is it required to specify all three members while Mongo suggests a single part connect string which probably must be covering the cluster thanks ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi All,
I really need some help here as I am unable to connect Pharo to MongoDB Atlas Cluster service: http://cloud.mongodb.com. (This service gives a free 500 MB MongoDB cluster on the cloud and thereafter larger on subscription) I have got stuck in my application development. The connection is thru MongoDB (client) Drivers and the connection string typically is given as 'mongodb+srv://<username>:<password>@yyyy.xxxxx.mongodb.net/<mydefaultdatabase>?retryWrites=true&w=majority" Ques 1.: is MongoClient required ? though Atlas service is a cluster the manual for Atlas states 'MongoDB drivers automatically attempt server selection following a cluster election or failover event. By default, the C driver immediately raises an error if its first attempt to select a server fails. ...' in any case MongoClient will probably fail in the following line at >>initializeWith: ... initialUrlStrings := initialUrls collect: [:each | each asMongoUrl asMongoUrlString ]. as asMongoUrl will not work with the scheme 'mongodb+srv' Ques 2: Can we directly connect thru class Mongo. However the specified connect string above would not go thru So can someone pls help on how to connect or work around this Sanjay Minni wrote > Hi > > can anyone pls help me with an example of connecting to a MongoDB Atlas > cluster (their cloud service). > > My Atlas cluster replica set is at the urls > yyyy-shard-00-00.xxxxx.mongodb.net:27017 > yyyy-shard-00-01.xxxxx.mongodb.net:27017 > yyyy-shard-00-02.xxxxx.mongodb.net:27017 > > The MongoDB Atlas website specifies the application connectstring as > > > 'mongodb+srv:// > <username> > : > <password> > @yyyy.xxxxx.mongodb.net/ > <mydefaultdatabase> > ?retryWrites=true&w=majority" > > I saw the doc / example on pharo-nosql/mongotalk but could not figure out > in > MongoClient - > > 1. how to get embed the username:password in the connectstring which i > feel > would be needed, > 2. how to specify the default database > 3. is it required to specify all three members while Mongo suggests a > single > part connect string which probably must be covering the cluster > > thanks > > > > > ----- > cheers, > Sanjay > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Thanks Stef,
I really am not technically knowledgeable to answer that question but all documentation is here https://docs.atlas.mongodb.com/tutorial/connect-to-your-cluster/ however after the technicals, i sort of noted somewhere that A database username and password is required in the connect string for a connect and there could be a slight variation in AWS / Azure / GCP hosting (I am using GCP but can change) Thanks for helping Stéphane Ducasse wrote > Hi > > what is the authentification protocol of this service? > > S > >> On 25 Mar 2021, at 15:12, Sanjay Minni < > sm@ > > wrote: >> >> Hi All, >> >> I really need some help here as I am unable to connect >> Pharo to MongoDB Atlas Cluster service: http://cloud.mongodb.com. >> (This service gives a free 500 MB MongoDB cluster on the cloud and >> thereafter larger on subscription) >> >> I have got stuck in my application development. >> >> The connection is thru MongoDB (client) Drivers and the connection string >> typically is given as >> 'mongodb+srv:// > <username> > : > <password> > @yyyy.xxxxx.mongodb.net/ > <mydefaultdatabase> > ?retryWrites=true&w=majority" >> >> >> Ques 1.: >> >> is MongoClient required ? >> >> though Atlas service is a cluster the manual for Atlas states >> 'MongoDB drivers automatically attempt server selection following a >> cluster election or failover event.

If you are on Windows, use curl and wire shark to see what is needed. Thats what I did to connect to RiakDB On 18 Mar 2021 11:43, Sanjay Minni <[hidden email]> wrote:

I dont know how the Pharo Mongo Driver works but if connecting to Mongo Atlas
would require a lot of exploring then could using the mongo C drivers thru uFFI or some other way be an alternative method to connect to Mongo Atlas https://docs.mongodb.com/drivers/c/ Regards Sanjay Minni wrote > Thanks Stef, > > I really am not technically knowledgeable to answer that question > but all documentation is here > https://docs.atlas.mongodb.com/tutorial/connect-to-your-cluster/ > > however after the technicals, i sort of noted somewhere that A database > username and password is required in the connect string for a connect and > there could be a slight variation in AWS / Azure / GCP hosting (I am using > GCP but can change) > > Thanks for helping > > > Stéphane Ducasse wrote >> Hi >> >> what is the authentification protocol of this service? >> >> S >> >>> On 25 Mar 2021, at 15:12, Sanjay Minni < > >> sm@ > >> > wrote: >>> >>> Hi All, >>> >>> I really need some help here as I am unable to connect >>> Pharo to MongoDB Atlas Cluster service: http://cloud.mongodb.com. >>> (This service gives a free 500 MB MongoDB cluster on the cloud and >>> thereafter larger on subscription) >>> >>> I have got stuck in my application development. >>> >>> The connection is thru MongoDB (client) Drivers and the connection >>> string >>> typically is given as >>> 'mongodb+srv:// >> > <username> >> : >> > <password> >> @yyyy.xxxxx.mongodb.net/ >> > <mydefaultdatabase> >> ?retryWrites=true&w=majority" >>> >>> >>> Ques 1.: >>> >>> is MongoClient required ? >>> >>> though Atlas service is a cluster the manual for Atlas states >>> 'MongoDB drivers automatically attempt server selection following a >>> cluster election or failover event.

Stef,
Just an addition to my previous mail on your query on protocol Per the MongoDB-atlas control panel the following connect protocol options are available. These come up when a database user is added thru Database Access option - SCRAM - X.509 Certificate - AWS IAM Hope this is the information you are looking for Sanjay Minni wrote > Thanks Stef, > > I really am not technically knowledgeable to answer that question > but all documentation is here > https://docs.atlas.mongodb.com/tutorial/connect-to-your-cluster/ > > however after the technicals, i sort of noted somewhere that A database > username and password is required in the connect string for a connect and > there could be a slight variation in AWS / Azure / GCP hosting (I am using > GCP but can change) > > Thanks for helping > > > Stéphane Ducasse wrote >> Hi >> >> what is the authentification protocol of this service? >> >> S >> >>> On 25 Mar 2021, at 15:12, Sanjay Minni < > >> sm@ > >> > wrote: >>> >>> Hi All, >>> >>> I really need some help here as I am unable to connect >>> Pharo to MongoDB Atlas Cluster service: http://cloud.mongodb.com. >>> (This service gives a free 500 MB MongoDB cluster on the cloud and >>> thereafter larger on subscription) >>> >>> I have got stuck in my application development. >>> >>> The connection is thru MongoDB (client) Drivers and the connection >>> string >>> typically is given as >>> 'mongodb+srv:// >> > <username> >> : >> > <password> >> @yyyy.xxxxx.mongodb.net/ >> > <mydefaultdatabase> >> ?retryWrites=true&w=majority" >>> >>> >>> Ques 1.: >>> >>> is MongoClient required ? >>> >>> though Atlas service is a cluster the manual for Atlas states >>> 'MongoDB drivers automatically attempt server selection following a >>> cluster election or failover event.
