SAP Host Agent is installed automatically during the installation of new SAP instances based on SAP NetWeaver 7.0 Enhancement Package 2 or higher. SAP Host Agent is upgraded automatically as part of the SAP instance, when you patch or upgrade the SAP kernel. However, you can also install and upgrade SAP Host Agent independently from an SAP instance.

You only need to install SAP Host Agent separately in the following cases:

  • There is no SAP system or instance on the host.

  • The SAP system running on the host is based on a release lower than SAP NetWeaver 7.0 including Enhancement Package 2 or SAP NetWeaver 7.2 and the host does not yet have an SAP Host Agent.

  • You have upgraded your SAP system to a release higher than SAP NetWeaver 7.0 including Enhancement Package 2 or SAP NetWeaver 7.2 and the upgraded system does not yet have an SAP Host Agent.
