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"

This Oracle doc
<https://docs.oracle.com/en/cloud/paas/autonomous-data-warehouse-cloud/user/connect-jdbc-thin-wallet.html#GUID-5ED3C08C-1A84-4E5A-B07A-A5114951AA9E>
explains the connectivity.
The unzipped wallet has the followiing files
ls DBAccess/
README cwallet.sso ewallet.p12 keystore.jks ojdbc.properties
sqlnet.ora tnsnames.ora truststore.jks
Thanks
