I'm trying to connect to a postgresql 13 DB hosted on my computer using spoon.
I get the following error when trying to connect
Error connecting to database [DW] :org.pentaho.di.core.exception.KettleDatabaseException:
Error occurred while trying to connect to the database
Error connecting to database: (using class org.postgresql.Driver)
The authentication type 10 is not supported. Check that you have configured the pg_hba.conf file to include the client's IP address or subnet, and that it is using an authentication scheme supported by the driver.

I did some digging and that's due to an outdated JDBC driver. Can anyone help me update the driver? I have located the driver directory but the guide on the website https://help.pentaho.com/Documentation/5.4/0D0/160/030
is just crap, they require you to have a distribute-files.bat file? Which I couldn't find anywhere.
You do not have to follow all the steps. Just pasting the JAR file in the directory is enough.

I have a question, I do not know how to solve it yet. Perhaps someone here has faced a similar issue.
We have a PostgreSQL DB hosted on Gcloud. We usually use a cloud proxy to connect with the database. It usually works very well!! In a nutshell the proxy connect a port from local host, to the actual DB host.
However this time, we want to connect it with Microsoft SSMS. We have not find an option where we can connect Microsoft SSMS with a DB running locally (this means connecting to a database on a port in local host).
The ultimate goal is to connect the database with Power BI. So if someone know how to connect a PostgreSQL DB hosted in GCloud to power BI that would also be very helpful!!
We have followed this tutorial:
https://www.anibalum.com.ar/2020/06/creating-linked-server-with-postgres.html
However we get the following error:
The linked server has been created but failed a connection test. Do you want to keep the linked server?
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "PAPERFLOWDB".

OLE DB provider "MSDASQL" for linked server "PAPERFLOWDB" returned message "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified". (Microsoft SQL Server, Error: 7303)

I am trying to connect a MySQL database via Google Cloud Data Fusion Wrangler. It's a very standard connection and I can connect and do every action with another tool (DBeaver). However, trying to connect with Wrangler, I am getting this message:
A server error occurred when testing the connection. Error: Exception occurred while handling request: string
Any suggestions? Thanks!
Please follow the instructions on https://cloud.google.com/data-fusion/docs/how-to/using-jdbc-drivers
Once done, you will be able to select the uploaded driver from the dropdown
For your requirement, you have to use JDBC Driver for connecting to MySQL database.You can use Public IP to setup connection to Wrangler.
Following are the steps to connect to MySQL database using Wrangler
Go to Hub in the Cloud Fusion instance and and select the required JDBC Driver.
Download the
driver and deploy it.
Go to Wranglers page and click on Add
Connection if you are connecting to MySQL for the first time.
Select
the MySQL database from the list of databases provided in Wrangler.
Add name and JDBC driver along with username, password and other connection arguments.
Click on test connection to check the connectivity.

I'm tying to use the connection string provided by DigitalOcean directly on the appsettings.json file, but shows error
ArgumentException: Keyword not supported: postgresql://XXXXX_user:xxxxxxxxxxxxx#db-trackbus-nyc3-xxxx-do-user-xxxxx-0.b.db.ondigitalocean.com:xxxxx/trackbus?sslmode (Parameter 'keyword')
Npgsql.NpgsqlConnectionStringBuilder.GetProperty(string keyword)
This is the exact connection string provided by DigitalOcean:
postgresql://xxxx_user:xxxxx#db-trackbus-nyc3-xxxx-do-user-xxxxx-0.b.db.ondigitalocean.com:xxxxx/TrackBus?sslmode=require
I'm using Npgsql nuget package, when the db was local was working fine using th regular connection string
"Server=xxx.0.0.x;Port=xxxx;Database=TrackBus;User Id=postgres;Password=xxxx;"
I've also tried this (private and public):
"Server=private-db-trackbus-nyc3-xxxxx-do-user-xxxxx-0.b.db.ondigitalocean.com;Port=xxxxx;Database=TrackBus;User Id=xxxxx_user;Password=xxxxxxxxxx;Integrated Security=true;"
Error:
An unhandled exception occurred while processing the request.
PostgresException: 28000: no pg_hba.conf entry for host "xxx.xxx.xxx.xxx", user "xxxx", database "TrackBus", SSL off
I searched this last 28000 exception but couldn't apply any solution found.
The connection string provided by DigitalOcean is for CLI:
postgresql://xxxx_user:xxxxx#db-trackbus-nyc3-xxxx-do-user-xxxxx-0.b.db.ondigitalocean.com:xxxxx/TrackBus?sslmode=require
You have to convert it to the format that appsettings.json uses and it will be like this:
"Server=db-trackbus-nyc3-xxxx-do-user-xxxxx-0.b.db.ondigitalocean.com;Port=xxxxx;Database=TrackBus;User Id=xxxxxxxx;Password=xxxxxxxxx;sslmode=Require;Trust Server Certificate=true;"
The sslmode=Require;Trust Server Certificate=true; is super important because the managed database in DigitalOcean has it that that one.
Also remember that all postgresql database by default are blocking remote connection, you have to add the permission on the pg_hba.conf file from the Postgresql installation folder.
I have just installed ColdFusion 10 and am trying to connect to MySql Server 5.1, but it is showing the error below:
Connection verification failed for data source: cfartgallery2
java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer
JDBC Driver]Error establishing socket. Unknown host: MySQL Server The
root cause was that: java.sql.SQLNonTransientConnectionException:
[Macromedia][SQLServer JDBC Driver]Error establishing socket. Unknown
host: MySQL Server
Finally after 2 days I solved my own problem of getting the above error. It was due to a missing ODBC connector.
Steps for resolving:
First download and install the ODBC connector of respective version as of your MYSQL server version.
Rhen install vcredist_x64 it is required for sql connectivity.
Then install any SQL Server to create the database and start connecting to it with the datasource you have created in tour CF Administrator.
Hope you can solve your problem with my instructions , if not then please post your queries below.
I am trying to connect the spark to tableau, I had installed Simba ODBC driver for 64bit, but I am facing issues while connrecting to spark.
ERROR:
Unable to connect to the ODBC Data Source. Check that the necessary drivers are installed and that the connection properties are valid.
[Simba][ODBC] (10000) General error: Unexpected exception has been caught.
In some doc, I saw that tableau requires some special license key. Can you please explain it
Basically spark works with the hive but with difference engine(algorithm for fetching data)
so initially to connect spark from tableau we need to install ODBC Hive drivers then spark driver.
Hive Driver:
http://www.tableau.com/support/drivers
Spark driver :
https://databricks.com/spark/odbc-driver-download
while installing spark on your cluster we need to configure thrift server with the hive server and need to give new port address.
you can go through using link to install spark in ambari :
http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.4/bk_spark-guide/content/ch_installing-spark.html
And the respective port address need to be specified in tableau while connecting.
If your Cluster is secured with user name and password we need to specify the Authentication as "USERNAME AND PASSWORD" and need to give credentials there..
Even though if it raises error, then look into below areas:
An incorrect port and/or service defined in the connection
Web Proxy or Firewall settings are blocking connection from Tableau Desktop
The data server is not started.
