WebinarUpcoming Webinar: Know What’s Changed – with NEW Server Configuration Monitor

Change management in IT is critical. But, even with a good change management process, changes are too often not correctly tracked, if at all. The configuration of your servers and applications is a key factor in their performance, availability, and security. Many incidents can be tracked back to an authorized (and sometimes unauthorized) configuration change, whether to a system file, configuration file, or Windows® Registry entry. Join SolarWinds VP of product management Brandon Shopp to discover how the new SolarWinds® Server Configuration Monitor is designed to help you.

Oracle Solaris agent upgrades

Beginning with version 6.3, LEM supports the 64-bit Java 8 Runtime Environment (JRE). Since Oracle did not release a 32-bit version of Java for Solaris, you must manually upgrade the agents running on these systems.

To upgrade your 32-bit Solaris SPARC and Solaris Intel agents, download the Solaris SPARC Agent and Solaris Intel Agent installers from the Customer Portal and run these installers on your Solaris systems.

Port requirements

If your log sources are located behind firewalls, see SolarWinds LEM Port and Firewall Information to open the necessary ports. See the SolarWinds Port Requirements for SolarWinds Products Guide for a list of all ports required to communicate with LEM.
