Question:
We want to run the Policy Server Snmp Agent and we have 3 questions :

1 - The script /etc/init.d/NetegrityAgent has no start/stop values; 
    Plus it can't be registered as service.
    How can we make this script registered as service in Unix ?

2 - The SNMP service will not start on server boot, as symlink only to
    runlevel 5 and system by default run on runlevel 3. How can we
    make it starting at runlevel 3 ?

3 - The SNMP service is executed as root, and it calls another script
    /opt/CA/siteminder/etc/snmp/conf/RunSubagent.sh which also
    executes as root java commands. How can we make it running for a
    specific user ?
Answer:
1 - In Linux, you have a service in order to start specific script :

  start shell script at boot time in linux redhat

2 - The solution given in 1 will apply for runlevel 3. 

3 - If you want to use a specific user, then you need to allow this 
    user to : 

    access port 8001 AGENTPORT=8001 
    access and execute files under INSTALL_HOME 
    execute the jvm JAVA_HOME
