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

unzip -p ojdbc8.jar META-INF/MANIFEST.MF

And this the setting for TNS_ADMIN

# FOLLOW THESE STEPS FOR USING JKS

# (3) Set the correct password for both trustStorePassword and keyStorePassword.

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 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"
        at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:489)
        at oracle.jdbc.driver.PhysicalConnection.<init>(PhysicalConnection.java:553)
        at oracle.jdbc.driver.T4CConnection.<init>(T4CConnection.java:254)
        at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:32)
        at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:528)
        at java.sql.DriverManager.getConnection(DriverManager.java:664)

This Oracle doc 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
