Splunk licenses and DB Connect

If you configure Splunk DB Connect to import data from a connected database into a Splunk Enterprise index, the amount of data Splunk Enterprise indexes counts towards your Splunk Enterprise license.

User permissions

Before using DB Connect, a logged-in user must have the ability to write to the $SPLUNK_HOME/var directory (%SPLUNK_HOME%\var on Windows hosts) and to $SPLUNK_HOME/etc/apps/splunk_app_db_connect (%SPLUNK_HOME%\etc\apps\splunk_app_db_connect on Windows hosts) and its sub-directories. For more information, see Use access control to secure Splunk data.


Java Runtime Environment (JRE) requirements

Before deploying Splunk DB Connect:

Java Runtime Environment (JRE) version 8 from Oracle

  1. Download and install the Server Java Runtime Environment version 8 from Oracle. Only use a supported JVM in server mode, not in client mode.
  2. Once you have installed the JRE, write down the path to the JRE directory, or $JAVA_HOME. You need the filepath when you are configuring DB Connect. When DB Connect prompts you to input the JRE Installation path in Configuration > Settings, be sure to input the complete JRE filepath you wrote down.

OpenJDK 8 from the Open Java Development Kit project

  1. Download and install the OpenJDK version 8 from the Open JDK project. Only use a supported JVM in server mode, not in client mode.
  2. Once you have installed the JRE, write down the path to the JRE directory, or $JAVA_HOME. You need the filepath when you are configuring DB Connect. When DB Connect prompts you to input the JRE Installation path in Configuration > Settings, be sure to input the complete JRE filepath you wrote down.

Java Runtime Environment (JRE) version 11 from Oracle

  1. Download and install the Server Java Runtime Environment version 11 from Oracle. Only use a supported JVM in server mode, not in client mode.
  2. Once you have installed the JRE, write down the path to the JRE directory, or $JAVA_HOME. You need the filepath when you are configuring DB Connect. When DB Connect prompts you to input the JRE Installation path in Configuration > Settings, input the complete JRE filepath you wrote down.

OpenJDK 11 from the Open Java Development Kit project

  1. Download and install the OpenJDK version 11 from the Open JDK project. Only use a supported JVM in server mode, not in client mode.
  2. Once you have installed the JRE, write down the path to the JRE directory, or $JAVA_HOME. You need the filepath when you are configuring DB Connect. When DB Connect prompts you to input the JRE Installation path in Configuration > Settings, be sure to input the complete JRE filepath you wrote down.

If you are unsure whether you have the correct version of Java installed, access DB Connect setup. On the first screen of the DB Connect setup or at Configuration > Settings > General you can specify the path to your JRE. If there is a problem with the Java install or the system $JAVA_HOME variable is incorrect, DB Connect displays an error message. It is important that you resolve any JRE issues before proceeding as DB Connect uses Java Database Connectivity (JDBC) to communicate with your databases.

Database and JDBC database driver requirements

Splunk DB Connect supports connections to many databases. You must install a Java Database Connection (JDBC) driver before you can connect to databases with DB Connect.

For more information about the databases that Splunk DB Connect supports, see Supported databases.

For information about connecting to unsupported databases with Splunk DB Connect, see Other databases.
