One listener but two listener binaries in multihomed environment

Hello

I have two Oracle versions installed (8.1.70 and 9.2.0.1)under Linux Advanced Server 2.1 (Red Hat),and there are two environments around different ORACLE_HOMEs. Almost everything works nice, we have several DB running different Oracle versions. But I am having trouble starting the OMS and/or connecting to it. I found out, that as the user oracle8 I can check the listener status using the binary from $ORACLE_HOME/bin and then I get a response coming from the version 9! When I check the listener status using the binary of version 9.2.0.1, the output is similar. Only the listener from version 9 was really started.

There seems to be some conflict with listeners, agents and OMS. The host seems to "freeze" every now and then for a couple of seconds, which can be seen when logged in via telnet. Only when I shut down the OMS and the agent the symptom disappeared.

When I restart the agent (agentctl start) and the OMS (oemctl start oms), I can't connect to it using the OEM console (VTK-1000). Then I can't shutdown the OMS because the authentication fails - in order to shutdown the OMS a password is required. I had to reset sysman's password to the default of oem_temp to be sure it is not my fault. There is still a process oemLauchOms running, which I had to kill manually. "oemctl ping oms" says that there is no OMS running, but starting the OMS I get a message that it is already running.

I checked several log files (dbsnmp.log, oem.nohup etc.) and found at times a message telling me something about "address already in use"). I also found error VXA-2012 and VXA-2008, and, of course, VTK-1000.

Can I choose any port for the OMS to listen to? Where do I configure it? Which is the default one?

At the time when I only had one Oracle Version running, I did not have these problems! I always switch environment according to the DB version I work with.

Any hint?
