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.

	Thanks
	Larry

I wish I had kept a MetaLink and/or documentation article I ran across once that states that the listener major version should match the DB major version. And we did run into problems trying to have one listener dole out connections for both 8.1.7 and 9.2.0 DBs. So, using in part the explicit auto-registration techniques described here in another thread, we have separate listeners, running of course on different ports.

HTH! GL!

Got a couple of clients who had us install 10G on some servers where some have DBs and some don't.

The installers activated the 10G listener (because we always use highest version) and we got 1000s of
 oerr tns 12618
12618, 00000, "TNS:versions are incompatible"

// *Cause: The two machines are running incompatible versions of TNS.
// *Action: Check the version numbers, and upgrade the machine with the
// smaller one.
