Server name for mongodb

[inageib]

I am trying to connect to mongodb from unidac and I supplied server name like this

cluster0-shard-00-00-xxxxx.mongodb.net

also port 27017, user name and password but I did not able to connect from Delphi !! why is that ? I was able to connect from mongodb compass btw

error:

Failed to read 66321 bytes from socket within 300000 milliseconds..

I am trying to connect to MongoDB Atlas not a local server

Perhaps the reason for this error is not UniDAC, but the client libraries that you use to connect to MongoDB Atlas.

Try to use the libbson-1.0.dll and libmongoc-1.0.dll client libraries from Devart ODBC Driver for MongoDB for Windows ( https://www.devart.com/odbc/mongodb/download.html ) to avoid this error. By default, 32-bit versions of these libraries will be installed to the "C:\Program Files (x86)\Devart\ODBC\MongoDB\Win32\" folder.
For example:

Code: Select all

  UniConnection1.ProviderName := 'MongoDB';
  UniConnection1.Server := 'cluster0-shard-xx-xx-xxxxx.mongodb.net';
  UniConnection1.Port := 27017;
  UniConnection1.Username := 'username';
  UniConnection1.Password := '********';
  UniConnection1.SpecificOptions.Values['MongoDB.BSONLibrary'] := 'C:\Program Files (x86)\Devart\ODBC\MongoDB\Win32\libbson-1.0.dll';
  UniConnection1.SpecificOptions.Values['MongoDB.ClientLibrary'] := 'C:\Program Files (x86)\Devart\ODBC\MongoDB\Win32\libmongoc-1.0.dll';
  UniConnection1.SpecificOptions.Values['MongoDB.ConnectionOptions'] := 'ssl=true&replicaSet=Cluster0-shard-0&authSource=admin';

  UniConnection1.Connect;

I installed odbc drivers and set all parameters now I get error:

Access violation at address 001948D3 in module 'libmongoc-1.0.dll'. Read of address 00000224.

We tested UniDAC 7.2.5 with MongoDB Atlas, Devart client libraries (libbson-1.0.dll, libmongoc-1.0.dll) and found no issues.
