Come upgrade and patch time, multiple oracle homes are easier.

Though there is more patching to do, it is quite a bit easier to deal with one application at a time.

When using multiple homes on Linux, I like to give each OH it's own directory for the Oracle Inventory.

My standard procedure is have /etc/oraInst.loc file look like this:

# linux group that Oracle is installed under inst_group=oinstall

#inventory_loc=/u01/app/oracle/product/10.2.0/10gr2dev/oraInventory
#inventory_loc=/u01/app/oracle/product/9.2.0/9ir2devb/oraInventory
#inventory_loc=/u01/app/oracle/product/9.2.0/9ir2test/oraInventory
#inventory_loc=/u01/app/oracle/product/10gR1/oraInventory
#inventory_loc=/u01/app/oracle/product/11.1.0/oraInventory
#inventory_loc=/u01/app/oracle/product/10.2.0/ee80/oraInventory

Keep in mind that OPatch and OUI will fail until you remember to uncomment the correct location.

Having experience Oracle Inventory issues in the past, this limits any corruption to a single Oracle Home.
