Oh you of little experience dealing with some Americans. I have seen single machines with Oracle installed like this:

/apps/oracle/bin
/etc/oracle/bin
/var/oracle/bin

u01/bin

And all on one machine. Each one a different version.

When it comes to some aspects of OFA I agree. And it comes to throwing in politically charged words like "slavishly" I agree too. But I don't agree that every SysAdmin and every DBA should just go install Oracle any d... place on the disk array they feel like installing it ignoring the cost to their employer every time any other employee or contractor or consultant comes in and tries to do some work and first has to create a map of where they put things.

One can adhere to a standard because it has value without being a slave to it. I, for example, could wear a kilt to work but still choose to wear slacks. Don't have to but I figure my legs are as ugly as some people's Oracle installations. And no one should have to see either.
