I download the duckdb jdbc driver and copy it to the install directory: C:\Program Files\Tableau\Drivers\duckdb_jdbc-0.2.9.jar
then I start the tableau , and choose the others jdbc drivers to connect,
set the configuration like this
try to connect to duckdb
the fail screen
any other configuration left? I already checkout the offical documents and found nothing related to this.
by the way, I can connect successfully using the Jetbrains Datagrip IDE after set the proper className and the same connection url?
the duckdb database behave like sqlite but for analytical workload. https://github.com/duckdb/duckdb

I'm new to OBIEE. I have version 12.2.1.4 installed on a Linux server. I installed the client tools on my Windows PC. Using the Administration tool I created a simple RPD which uses only two tables. For this I had to first create an ODBC DSN to connect to my DB/2 database.
Next, I uploaded the RPD to the OBIEE server using the datamodel cli tool. When I go to the http://hostname:9502/analytics page and select to create a new analysis, it shows me the name of the repository and the two tables. I selected a couple of columns and clicked on the Results tab.
At this point, I get an error message: ODBC error state: IM002 code: 0 message: [DataDirect][ODBC lib] Data source name not found and no default driver specified
I had used the em console to create a JNDI connection to DB/2. But, from the message it seems that it is trying to use the ODBC connection that was used when creating the RPD on my PC.
How do I change the connection that the server is using?
The server needs to be able to reach the data source. EM JNDI connections have nothing to do with it, but rather the server (server OS - not the application) has to reach the source.
You need to update your ODBC settings on the Linux server: https://support.oracle.com/epmos/faces/DocContentDisplay?id=2570997.1
I have created an Autonomous Transaction Processing database in Oracle Cloud. There are no ready-for-use JDBC links around, but there are "wallets". There is an instance wallet and regional wallet. Oracle says one of them, preferably instance wallet, should be used to connect to this DB instance.
A wallet is a ZIP file with a dozen of files inside. I've downloaded an instance wallet and unzipped it. Now I'm trying to connect DataGrip to this instance.
There is a TNS connection type in DataGrip and there is a famous tnsnames.ora in the wallet, so I guess I should use them. TNS connection type accepts a TNSADMIN parameter, which, I guess, is a directory of that wallet. tnsnames.ora from the wallet lists a few service names, AFAIU they differ by their priority, e.g. one for low-priority queries, another for medium-priority and one for the highest priorities question. I'm OK with medium priority, so I did this:
As you see, I'm getting an error:
[08006][17002] IO Error: The Network Adapter could not establish the connection
SSO KeyStore not available.
I've googled around, but this topic seems to be complicated. Oracle has a lot of connection parameters with certificates involved in the connection process, and I'm really new and I just want to connect to this instance. Why it should be so complicated? Can I use this wallet directly in DataGrip?
It seems that I've did everything correctly and the only problem is actually the driver version.
As of today, 2021-02-02, the latest available Oracle driver version in DataGrip is 19.8.0.0:
To fix the issue I've just created another Oracle driver in DataGrip and manually provided the latest JARs:
Go to the Oracle Database 21c (21.1) JDBC Driver & UCP Downloads
Download the ZIPped JDBC driver and companion JARs corresponding to your Java version: 8 or 11. Or just download the version for Java 8 (ojdbc8-full.tar.gz). It should work with any modern Java.
Create new subdirectory in the DataGrip's drivers directory for you driver. Something like ~/.config/JetBrains/DataGrip2020.3/jdbc-drivers/Oracle/21.1 for Linix.
Unzip the driver in that directory.
Configure new driver in DataGrip. Just clone the existing Oracle driver and replace the "Driver Files" with the ones from the ZIP.
Use this new driver to connect to the instance:
DataGrip 2021.1 provides Oracle JDBC Driver 21.1.0.0 with all required jar files.
Also, read DataGrip article about connection to Oracle using wallets.
I am new to Programming. I am learning JAVA and for DB i wanted to learn Oracle so I downloaded sqldeveloper from Oracle website. It was a zip file so I didnot have to install anything, simply extracted it. When I open the sqldeveloper and try to make a new connection, it shows error.
Test failed: IO Error: The network adapter could not establish the connection.
I am not sure what to put in username and pwd. and i am also not sure if i have to connect this to jdk or jre or set classpath for database.
Can anyone help me?? I have uploaded the snapshot of the error too.
You downloaded a client.
You did NOT download the server component though - the actual database.
SQL Developer just allows you to work with an existing database.
No worries, you're not that far away. You have several options.
Oracle Database Express Edition (XE) - it's completely free.
We also have a VirtualBox appliance you can use for personal learning purposes, also completely free.
I talk about this and give step by step instructions here.
Check if oracle service, TNSListener service is up and running before trying to make any new connection from sql developer.
Even if TNS Service is down , connection can not be established with oracle instance.
Has anyone ever connected to a MySQL remote server using uipath? Is this possible. I've tried using the standard activities but am unable. I understand that I may need to install the odbc driver, then create a connection. Is it possible to then send sql from uipath to the linked server.
Thanks for the information. I followed the steps and able to solve the problem.
Install mysql
Install Mysql odbc driver
create USER DSN
While creating connection use the ODBC DATA SOURCE option
In next window select the DSN created in third step under system or user Data source name
Thanks for help
You can use connect to MYSQL database using UIPath, by installing Mysql-ODBC connector of 32-bit(x86) and creating a system/user DSN.
I have tried and it is working fine.
Please revert for any clarifications.
You can connect to the remote server and pass the SQL queries to fetch the data.
Which version of UiPath you using now (Community or Enterprise)?
