Hi Pankaj,
Did more of digging around this ..
From 12.7 ( same should be for 12.52SP1), I see that start-all/start-ps and stop-all/stop-ps script are identical.


So what both of these startup script does is , it invokes :
"/opt/CA/siteminder/bin/smexec" executable
and this is configured to start both policy server service and one view montior service.
This is hardcoded, so there is noway you can choose to stop running one view montior automatically.
You can however disable it manually from Siteminder Policy server management console ..

But this will get enabled again next time you run start-all or start-ps script.
In windows OS however, as this run as an indepedent service, you can disabe it permanently from starting up :

Now coming back to linux, the only workaround I found (though not very appropriate) is by modifying the :
/opt/CA/siteminder/bin/smmon.sh file and commenting the startup code here :
#"$NETE_JRE_ROOT/bin/java" -Xmx64m -Dnete.ps.root="$NETE_PS_ROOT" -classpath "$NETE_PS_ROOT/lib/smconapi.jar":"$NETE_PS_ROOT/lib/smmon.jar" com.netegrity.smmonagent.SmMonAgentRun
Now, if you try to run either start-all or start-ps , the One View monitor service is not started :
[root@shruj01-I1850 bin]# start-ps
SiteMinder Policy Server is running
SiteMinder Health Monitor is not running
[root@shruj01-I1850 bin]#

It would have been good to have an option to disable this service in graceful manner OOTB like windows.
Hope this helps.
