Why not configure the aix servers as a hacmp cluster and define the oracle instance as a resource group? With nfs mounts it only takes a couple of minutes to complete the failover and bring up oracle on the backup server.

we will be configuring two aix servers as a backup to each other, with a 740 having the database files NFS mounted on the two aix servers. we will define the same oracle 7.3.4 instance to each machine and only one will be active, the second instance only to be started if the primary aix server is dead. if the primary instance is already running, will there be a locking mechanism that will prevent the other instance from starting up? this is to see if there is a possiblity of corruption if someone makes a mistake and starts the second instance when the primary is already running

thanks for the reply... the company is not headed in the HACMP direction and would rather have 2 servers running as primary and a secondary for failover
