Do you have the privileges to run as root using the Privilege Delegation tool? Warning The "requiretty" flag is set in the sudoers file on the remote host, and as a result, the user will not be able to run sudo over ssh
Either set the "oracle.sysman.prov.agentpush.enablePty" property to true in the "/u01/app/oracle/fmw/oms/sysman/prov/agentpush/agentpush.properties" file, or disable the "requiretty" flag in the sudoers file
You can also ignore this warning and continue in which case the root.sh, any preinstallation or postinstallation scripts specified with run as root enabled will not be run and you have to run them manually after installation
