Re: listener... which home?

see the possibilities of srvctl:
srvctl add listener -h

Adds a listener configuration to the Oracle Clusterware.

Usage: srvctl add listener [-l <lsnr_name>] [-s] [-p "[TCP:]<port>[, ...][/IPC:<key>][/NMP:<pipe_name>][/TCPS:<s_port>] [/SDP:<port>]"] [-o <oracle_home>] [-k <net_num>]

    -l <lsnr_name>           Listener name (default name is LISTENER)
    -o <oracle_home>         ORACLE_HOME path (default value is CRS_HOME)
    -k <net_num>             network number (default number is 1)
    -s                       Skip the checking of ports
    -p "[TCP:]<port>[, ...][/IPC:<key>][/NMP:<pipe_name>][/TCPS:<s_port>] [/SDP:<port>]"       Comma separated tcp ports or listener endpoints
    -h                       Print usage

there you can define a oracle_home. This would not make sense if you MUST use the grid home - CRS would know about the grid_home quite well. So you can use any oracle_home which is supported in combination with the version of grid_home.

Still I'd suggest to use the listener of your CRS as long as possible.

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 patch/version...
