Environment
The
SQLException: Protocol violationis usually caused by the JDBC driver. Please ensure that you're using the correct Database JDBC Driver in your Bamboo instance, considering your Bamboo version and Oracle version.
Cause
If you're using Oracle's ojdbc7.jar (version 12.1.0.1) to connect to your Oracle database, you're hitting a known bug with the driver itself as discussed in this StackOverflow post.
BAM-18276 - The Oracle JDBC Driver bundled with Bamboo 5.15.x is buggy . This is fixed in Bamboo 6.2.0
Solution
Resolution
Stop Bamboo.
Download ojdbc8.jar version 12.2.0.1.
Update your JDBC driver by replacing the existing JAR file inside the
$BAMBOO_INSTALL/libStart Bamboo.
