In 11.2 when you have grid infrastructure installed (which is, if I'm not 
mistaken, required when using ASM), then the listener must be running from the 
grid home (in your case called asm) when you want to control it via srvctl.
It is still possible to start a listener from the db home by using lsnrctl (and 
the listener.ora file), but this listener can't be controlled via srvctl (and 
thus can't benefit from oracle restart).

Subject: listener... which home?

hi guys,

 so, we have two homes in a server. One is /u01/app/asm, obviously this is the 
ASM home. it's an 11g home as well. Then we have the 
/u01/app/oracle/product/11.2.0 home which is the DB home. There is a single DB 
in this server. The listener is running from /u01/app/asm/bin/tnslsnr.... which 
to me is odd. Is there any reason you can think of for this? (I already asked 
the previous owner of this server and they replied it was "by design"). I can 
see some benefits (like in theory you don't need to bring down the listener for 
$OH patching... and you usually have the ASM home in the latest 

  what cons do you find in this?
