Ah, no.

$ show tns

$ lsnrctl

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC))) TNS-12618: TNS:versions are incompatible

ORACLE_HOME = 920 You are executing "lsnrctl" from a 10.2 ORACLE_HOME

My database and environment here is 9.2 so I'm executing the 9.2 lsnrctl command but running a 10.2 listener.
This server has six 9.2 databases and no 10.2 DB yet.

On your Linux server R U running a 9i release too? If not, you won't have the problem.

My suggestion was soft link
mv 9.2/bin/lsnrctl 9.2/bin/lsnrctl.92
ln -s 10.2/bin/lsnrctl 9.2/bin/lsnrctl

Someone has said they may not be enough going back to my original post

I'm confused:

oracle> lsnrctl status

LSNRCTL for Linux: Version - Production on 24-MAY-2006 12:19:10

Is this different on other platforms?

      We are running the highest listener. The problem with 10G is it isn't compatible with lower releases.
 For example if you do a "lsnrctl status" etc.

        Typically what happens is some monitor program like BMC's Patrol or OpenView issues a command using the lsnrctl from whatever ORACLE_HOME exists for the database it is monitoring. 10G doesn't like that if it isn't a 10G OH.     

        Was wondering if a more elegant/problem-free solution than my soft link exists.
