I've tried the ODBC connection in Rattle 5.1 many times with the same error.
Error in sqlTables(crs$odbc) :
first argument is not an open RODBC channel
In addition: Warning messages:
1: In RODBC::odbcDriverConnect("DSN=ORCL", believeNRows = TRUE) :
[RODBC] ERROR: state 28000, code 1005, message [Oracle][ODBC][Ora]ORA-01005: null password given; logon denied
2: In RODBC::odbcDriverConnect("DSN=ORCL", believeNRows = TRUE) :
ODBC connection failed
I've even hard-coded the password in OCBC.ini but it still doesn't work.
RODM_open_dbms_connection with the same DSN works fine.
I figured this out. I downloaded R 3.4.3 on another laptop and the ODBC connection works. It's R 3.5.0 that it has problem with. Looks like Rattle 5.1.0 may not be compatible with R 3.5.0 yet.

I recently switched to ubuntu and when I installed and tried to create a connection on Oracle SQL Developers 22.2.1 I get a error
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Ive tried changing the ports and switching between JDK 19,17 and 11 non of them seem to fix the error, all the guides that i can find on this error seem to be specifically for windows.
any help is appreciated and apologies if I have couldnt explain my problem clearly.
Testing connection of server should produce successful but its giving Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
I have a running DBeaver connection to a DB2 database and now I would like to connect also in Python with the DB2 database securely over SSL. As authenticating I would like to use my windows account instead of giving a PW and UserID, to do so in DBeaver I changed:
javax.net.ssl.keyStoreType = Windows-ROOT
javax.net.ssl.trustStoreType = Windows-MY
Is this also possible with the Python connection?
I tried the following to set up the connection:
import ibm_db
connID = ibm_db.connect('DRIVER={IBM DB2 ODBC DRIVER};'
'DATABASE=XXXX;'
'HOSTNAME=XXXXYYY.net;'
'PORT=9797;'
'PROTOCOL=TCPIP;'
'SECURITY=ssl;'
'SSLSERVERCERTIFICATE=C:/Users/..../cert.cer;'
, '', '')
if connID is None:
print("\nERROR: Unable to connect.")
exit(-1)
print("Connected!")
I get the following error:
SQLCODE=-30082][CLI Driver] SQL30082N Security processing failed with reason "17" ("UNSUPPORTED FUNCTION"). SQLSTATE=08001

I'm using:
Python version 2.7.17
Ibm_db version 3.0.1
I am getting
cx_Oracle.DatabaseError: ORA-12170: TNS:Connect timeout occurred error while connecting oracle from python.
I have installed python 3.7.0 and instantclient_11_2.
Below are the process i am doing,
import cx_Oracle
dsn_tns = cx_Oracle.makedsn( '<ip>', 1521, service_name = '<given service name>')
connection = cx_Oracle.connect('user', 'pwd', dsn_tns)
I have set system veriable PATH where oci.dll is present.
What could be wrong?
Try:
connection = cx_Oracle.connect('user', 'pwd', cx_Oracle.makedsn( '<ip>', '1521',None,'<given service name>'))
Looks the same but works different in my ubuntu server.
Also make sure to put the port between ' '
You should also be able to use the following connect string if the database resides on the same machine:
connection = cx_Oracle.connect('user/pwd#localhost/service_name')
Note that a service_name value is required. You can't use the empty string!
I have virtuoso 6.1 in ubuntu. I was loading a dbpedia RDF but the server where virtuoso is setup disconnected while doing it, giving me this error:
Error 08S01: [Virtuoso Driver]CL065: Lost connection to server at line
2 of Top-Level: rdf_loader_run()
Since then I only get this error:
Error S2801: [Virtuoso Driver]CL033: Connect failed to localhost:1111
= localhost:1111.
I tried to kill virtuoso and restart it but nothing changes, I also tried changing the port but it still tries to connect to port 1111, and when I specify the new port it gives me the same message. Does anyone knows how to solve this issue?
I have installed gerrit server setup in localhost. And after making the successful connection the Web UI has been launched. There i have registered with my gmail id in "Sign in with a Launchpad ID" option.
Its worked earlier, but now it shows the error "Provider is not supported, or was incorrectly entered." when i try to login. I had searched a lot and found some solution regarding the security issues in the installed java in the system. I have Oracle Jdk8 not OpenJdk in my system. so should i have to switch to Open Jdk. Here is my error log messages from log file.

Issue Fixed !
As i have been using Oracle Java 8, i have installed Open Jdk 7 with the following commnad.
sudo apt-get install ca-certificates-java
But issue resolved only when i have changed java home variable in gerrit.config file.
javaHome = /usr/lib/jvm/java-7-openjdk-amd64/jre
Now the issues fixed for me..
