Resolution steps:

You may be missing some libraries (UIP –> SAS upgrade in place issue sometimes observed with problematic depot, tip: always run depot checker utility).

Copy these files:

1. jackson-core-asl-1.8.6.jar,
2. jackson-jaxrs-1.8.6.jar
3. jackson-mapper-asl-1.8.6.jar

from < SAS Configuration>Config/Lev1/Web/SASEnvironmentManager/server-5.8.0-EE/hq-engine/hq-server/webapps/ROOT/WEB-INF/lib/ to < SAS Configuration Directory >/Lev1/Web/SASEnvironmentManager/agent-5.8.0-EE/bundles/agent-5.8.0/pdk/lib/

Start SAS Environment Manager Agent service using Windows Services manager or using command prompt option (<SAS Configuration>\Lev1\Web\SASEnvironmentManager\agent-5.8.0-EE\bin\hq-agent.bat start)
