Thanks Jorn,
Only running in REPL in local mode
This works fine connecting with ojdbc6.jar to Oracle 12c.
cheers

Mich,
All looks fine.
Perhaps some special chars in username or password?
it is recommended not to use such characters like '@', '.' in
your password.
Best, Kuassi

Hi,
From which release is the ojdbc8.jar from? 12c, 18c or 19c?
I'd recommend ojdbc8.jar from the latest release.
One more thing to pay attention to is the content of the
ojdbc.properties file (part of the unzipped wallet)
Make sure that ojdbc.properties file has been configured to
use Oracle Wallet, as follows (i.e., anything related to JKS
commented out)
/oracle.net.wallet_location=(SOURCE=(METHOD=FILE)(METHOD_DATA=(DIRECTORY=${TNS_ADMIN})))//
//#javax.net.ssl.trustStore=${TNS_ADMIN}/truststore.jks//
//#javax.net.ssl.trustStorePassword=<password_from_console>//
//#javax.net.ssl.keyStore=${TNS_ADMIN}/keystore.jks//
//#javax.net.ssl.keyStorePassword=<password_from_console>/
Alternatively, if you want to use JKS< then you need to
comment out the firts line and un-comment the other lines
and set the values.

Hi,
The connection from Spark to Oracle 12c etc are well
established using ojdb6.jar.
I am attempting to connect to Oracle Autonomous Data
warehouse (ADW) version
*Oracle Database 19c Enterprise Edition Release 19.0.0.0.0*
Oracle document suggest using ojdbc8.jar
<https://urldefense.com/v3/__http://ojdbc8.jar__;!!GqivPVa7Brio!Msuw5mr2YjeHSLbBSlNvs8rqL7T_-eWFfdsamiYduARIsECZqEzUTG8hd-v1x8KwcQ$>
to
connect to the database with the following URL format using
Oracle Wallet
"jdbc:oracle:thin:@mydb_high?TNS_ADMIN=/home/hduser/dba/bin/ADW/DBAccess"
This works fine through JAVA itself but throws an error
with Spark version 2.4.3.
The connection string is defined as follows
val url =
"jdbc:oracle:thin:@mydb_high?TNS_ADMIN=/home/hduser/dba/bin/ADW/DBAccess"
where DBAcess directory is the unzipped wallet for
Wallet_mydb.zip as created by ADW connection.
The thing is that this works through normal connection via
java code.using the same URL
So the question is whether there is a dependency in Spark
JDBC connection to the ojdbc.
The error I am getting is:
java.sql.SQLRecoverableException: IO Error: Invalid
connection string format, a valid format is: "host:port:sid"

The unzipped wallet has the followiing files
