The way I have installed Oracle software, owned by, say oracle, oracle1, oracleg, and to fool the installer into thinking that there is no Oracle software installed is by renaming the /var/opt/oratab to something like oratab_<instance>. After the installation I add all the databases to the new oratab file. The problem I ran into is that Oracle keeps on trying to use port 1521 by default. I have to edit the listener.ora, tnsnames.ora, Rename the listener. Maybe someone out there can offer better ways to deal with this issue. I had the same problem with dbsnmp. For the newest intelligent agent to discover your other services I had stop dbsnmp, unset the TNS_ADMIN variable and start dbsnmp. I hope this helps. Thanks Ana E.

Other than maintaining multiple inventory , is there a better solution for this ? (In my case, the number of inventory will not be more than 2) But, we want to use DBSNMP also. This by default reads /etc/oratab to get the list of oracle homes . How do make it read my oratab (say /etc/new/oratab) also ? All i want is : dbsnmp should discover all my instances ! This is where i'm stuck . Can someone guide me ? Any suggestions please ?! Regards, Prem. -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
