Ah, no. $ show tns oracle 18603 1 0 Mar 23 ? 3:39 /oracle/10201/bin/tnslsnr LISTENER -inherit $ lsnrctl LSNRCTL for Solaris: Version 9.2.0.6.0 - Production on 24-MAY-2006 13:28:26 Copyright (c) 1991, 2002, Oracle Corporation. All rights reserved. Welcome to LSNRCTL, type "help" for information. LSNRCTL> status 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 Larry -----Original Message----- From: Jesse, Rich [mailto:Rich.Jesse@xxxxxx] Sent: Wednesday, May 24, 2006 12:20 PM To: Wolfson Larry - lwolfs; oracle-l Subject: RE: Listener with mixed releases I'm confused: oracle> lsnrctl status LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 24-MAY-2006 12:19:10 Copyright (c) 1991, 2005, Oracle.

Rich -----Original Message----- From: Wolfson Larry - lwolfs [mailto:lawrence.wolfson@xxxxxxxxxx] Sent: Wednesday, May 24, 2006 11:58 AM To: Jesse, Rich; oracle-l Subject: RE: Listener with mixed releases Rich, 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.
