Hi mariam_34273,

Please note that the password for m001-student is m001-mongodb-basics. Here is the screenshot of my connection parameters.

Hi All, I am getting the same error “authentication fail” with given credentials, can someone please help. I need to finish this class today as it is the last day.

Hi All, I have used the credentials used above (same from course) but still getting the following error msg:

"Could not connect to MongoDB on the provided host and port ".

Need help in connecting compass to proceed to rest of the course and is required for the labwork due today. Thanks in advance.

$lookup across 2 databases Working with Data

This is my pipeline db.getSiblingDB("mai_inventory_service").view_product_hpp.aggregate([ { $lookup: { localField: '_id', from: 'view_main_dealer_package_products', foreignField: 'product_id', as: 'package_product', } } ])

Password: m001-mongodb-basics for cluster: “cluster0-shard-00-00-jxeqq.mongodb.net”, user: “m001-student”

Try pinging the cluster from your command line:

  ping cluster0-shard-00-00-jxeqq.mongodb.net

And if 27017 port is getting used in some other process, you need to stop the process. In linux, you can find top processes using top command.

Had the same error, then noticed that I copied a space before the username. Might be the case for others, too!

Tyn_06328 · 2019-02-15T12:47:27.937Z

Hi , you can try setting your IP whitelist into this. Just go to your atlast account, then click cluster, then Security.

$lookup across 2 databases

m001-mongodb-basics

Yeah it worked, When i tried as you said. The mistake is only in typing the username and password manually. But i didn’t get what these host name, replica set names are. Still having a doubt on those.

$lookup across 2 databases

But i didn’t get what these host name, replica set names are.

Host Name: Hostname is used to connect to a mongod instance. This hostname can be a hostname, an FQDN, an IPv4 address, or an IPv6 address.

Replica Set Name: Replica Set is a set of servers with the copies of data. Usually, it is a set of 3 mongod servers with 1 Primary and 2 Secondary servers. So, replica set name is the name given for whole replica set. More information is given here in docs-replication. And there is M103 course which covers the topic in detail.

after using above solution it connects but I got following error in red lines:
An error occurred while loading navigation: ‘not master and slaveOk=false’: It is recommended to change your read preference in the connection dialog to Primary Preferred or Secondary Preferred or provide a replica set name for a full topology connection.

Ramachandra_Tummala · 2020-10-04T09:44:12.577Z

Are you connecting to your Sandbox cluster or Class cluster?
Try with read preference as Primary preferred

Shubham_Ranjan · 2020-10-06T04:02:24.065Z

Hi @Dhananjay_Wadhavane,

Please use srv type connection string. It will always connect you to the Primary node of the Atlas replica set.

You can get the srv connection string for your cluster from your Atlas account.
