Introduction to NetWorker Runtime Environment (NRE)

The NetWorker server, NetWorker Management Console (NMC) server, and NetWorker Management Web UI (NWUI) server rely on a Java Runtime Environment (JRE) to operate. JRE must be installed on the NetWorker server, NMC server, NWUI server, and any host used to access the NMC. 

As of January 1, 2019, Oracle no longer supports or updates Java Runtime Environment (JRE) 8 unless users have a license agreement with Oracle. To provide support and access to Java security updates, Dell Technologies worked with Oracle to integrate JVM/JRE with Dell Technologies Data Protection (DP) products. The NetWorker specific Java package is called NetWorker Runtime Environment (NRE). JRE licensed directly from Oracle may still be used.
 

NOTE: Keep NRE up to date as this updates the embedded JRE package.


Existing NetWorker users that want to use NRE should reference the NetWorker Runtime Edition Readme Guide. The NetWorker Installation Guide and NetWorker Release Notes provide additional information.
