When mapping Spectrum attributes to Service Desk attributes using NIM (http://OCServer/ca-nim-sm/ui/login.jsp). The updated mappings are lost after a restart of the OneClick Tomcat.
e.g in the following example the Spectrum severity attribute is mapped to the ServiceNow impact attribute:
After the restart of Tomcat, the mapping reverts to the default mapping:
severity --> severity
In order for the custom mapping of the of the Spectrum and Service Desk tool attributes to be maintained after a Tomcat restart, you need to set the mapping in the $SPECROOT>\custom\svdsk\config\nim-mappings-config.xml file.
See the following example:
Save the file and the change will be maintained after a Tomcat restart. You should also be able to see the updated mapping in NIM.
