If you want just to make the server up and running with loosing few functionality like “Node Manager cannot query if a PID is alive nor kill a particular process or monitor a process” then please add below parameter to the nodemanager.properties file and try to restart the nodemanager again.

NativeVersionEnabled=false

If you want a permanent solution then please make sure all the reported missing libraries in logs are present in server/native/solaris/sparc or in /usr/ucblib

you can search for the required missing packages using this url http://pkg.oracle.com/solaris/release/en/index.shtml
