The SAP J2EE engine is started by the SAP dispatcher which is under the protection of the Sun Cluster HA for SAP. If the SAP J2EE engine fails, the SAP dispatcher will restart it.

  1. Using the SAP J2EE Admintool GUI, change the ClusterHosts parameter to list all logical hosts for the application server and port pair under dispatcher/Manager/ClusterManager.


    as1–1h:port;as2–1h:port ...

  2. Configure the com.sap.instanceId property in the file j2ee-install-dir/additionalproperties.


    com.sap.instanceId = logical-host-ci_SAPSID_SYSNR

  3. Configure the sapbasis.ashost property in the file j2ee-install-dir/server/services/security/work/R3Security.properties.


    sapbasis.ashost = logical-host-ci

  4. Configure the host property in the file SDM-dir/program/config/flow.xml.
