installing 2 oracle instances on one host


I am running ecc6 system on oracle 10.2 and AIX as os.

I would like to install a second ecc6 instance (1 Oracle installation - 2 instances).

I already read notes 98252,350251,21960.

except these notes are there any prerequsites/installation instructions?

Or should i install the second instance the same way as i installed the first? (according to the installation guide)

i guess i need to add additional file systems to the new SID

How does the sap installation know that this is a second instance and that an oracle DB installation is not required?

    because there are different enviroment variables depending on the sap users ( sidadm and sapserviceSID ).

      one more question regarding orainventory,

      according to note 350251 in order to avoid all kind of errors during installtion , the oraInst.loc (which is in my case located on /etc and in /oracle/product which is the oracle_home dir) should be edited.

      according to the note the inventory_loc=/oracle/sid/oraInventory, and if additional instance is added the inventory_loc should be changed to /oracle/new_sid/oraInventory.correct me if i'm mistaken - this note is talking about adding additional instance with new oracle_home.

      in my situation the inventory_loc=/oracle/oraInventory - no sid in between.

      the oraInventory dir is located in /oracle/product which is the oracle_home - how should i edit the oraInst.loc file for the new added instance , or maybe this note is not relevant in case of sharing oracle_home?
