Closed as program error.
Error description
The CAE Server can have a variety of problems if the server log contains the following error message: * java.lang.InternalError: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable. * This error is caused by the existence of a non-empty value for the DISPLAY environment variable in the environment under which the CAE Server is running. Usually this variable should not be set, but sometimes, for example, the userid of the CAE Server may have this variable set in its initialization profile (e.g. in the .profile file in its USS home directory ).
Local fix
This APAR has 2 possible Workarounds. . 1. Change the DISPLAY value in CAE Server user's .profile to 'DISPLAY=' or remove the DISPLAY parm. . 2. Modify the CAE Server Script 'start_cae_server' to basically ignore the DISPLAY: ...add this line: -Djava.awt.headless=true \ in the CAE Server Script: /cqmv3r1/bin/start_cae_server EXAMPLE: ${CQM_HOME}/bin/runjava -m +a +j \ $CQM_HEAP_ARG \ $CQM_CAE_CACHE_LOCALHOST_ARG \ -Djava.class.path="$CLASSPATH" \ -Djava.awt.headless=true \ $CQM_LOGGING_ARG \ $TZ_ARG \ $LOCAL_PORTAL_PORT_ARG \ $RMI_PORT_RANGE_ARG \ $CAE_AGENT_LISTENER_PORT_ARG \ $CAE_SECURITY_ARGS \ $CAE_TRUSTSTORE_ARG \ $CAE_KEYSTORE_ARG \ -Djava.security.policy=${CQM_HOME}/bin/java.policy \ com.rocketsoft.nm.licensing.Boot com.rocketsoft.nm.discovery.TopologyServer \ -serverPolicyClass com.rocketsoft.nm.qm.topology.QMServerPolicy \ -modules $CQM_VAR_HOME \ $WEBSERVER_PORT_ARG \ $JDBC_PORT_ARG \ -httpRoot $CQM_VAR_HOME $* &
