Java Runtime Environment (JRE)

Before deploying Splunk DB Connect, install the Java Runtime Environment (JRE) from Oracle Java SE Downloads.

  • Supported versions: DB Connect 1.1.x requires Java 1.6 or 1.7 only. DB Connect 1.2 requires Java 8 only. DB Connect 2.0 requires Java 8 only.

Note: Only the Oracle JRE is certified and supported for use with Splunk DB Connect. Customers have reported problems when starting the Java Bridge Server under alternate JREs or JDKs such as OpenJDK or IBM Java. You can download the Oracle JRE and JDK packages from http://www.oracle.com/technetwork/java/javase/downloads/index.html.

Splunk Licenses and DB Connect

If you configure DB Connect to output data from a connected database into a Splunk index, the amount of data indexed does count towards your Splunk license. However, performing database lookups against a connected database in DB Connect does not count towards the license.

For more information about Splunk licenses, see "How Splunk licensing works."

Will DB Connect be updated anytime soon to work with Java 8, specifically to use with SQL Server and ODBC databases?
