This procedure is defined in the CA eHealth and CA SPECTRUM Integration and User Guide - #5177 page 31.


This procedure can be implemented  to eliminate the lag time caused by excessive DNS


lookups. This will stop them from happening in the first place.


To begin you will need to stop Spectrum Tomcat.



The first step in this procedure  is to copy a file called mapping-overrides.xml from:



$SPECROOT/tomcat/webapps/spectrum/WEB-INF/ehlth/config/


to 


$SPECROOT/custom/ehlth/config/



Once mapping-overrides.xml is there you will need to edit the file and create a


mapping override for the eHealth server.



To do this you  will need to  uncomment the <landscape-override> block of the file, located


near the bottom, and insert the eHealth server information like this:



<landscape-override>


<landscape-handle>DEFAULT</landscape-handle>


<server-map>


<server-override>



<topology-ip><insert_eHealth_Server_IP_here></topology-ip>



<url-host-address><insert_eHealth_FQDN_here></url-host-address>


<url-port><insert_eHealth_port_here></url-port>


</server-override>


</server-map>


</landscape-override>



Once this is done, save the file.


Then navigate to


Administration->eHealth Configuration on the SPECTRUM OneClick start page.



At the very bottom of the page, you will need to click the button labeled


Update Landscape Overrides. This will read the overrides that you just set.



Now, any OneClick Console sessions will have to be closed and reopened.



Right-click menus should no longer use DNS lookups to get the Fully Qualified Domain Name from the eHealth server once this is in place.
