http://download-west.oracle.com/docs/cd/A81042_01/DOC/server.816/a76956/onlinere.htm#3981 would be nice reference. What i was trying to communicate was this: If the log is not multiplexed and the only log member is not avbl for writing then LGWR cannot write and the db instance will go down. However, if it is multiplexed then an error will be logged to the alert.log but the db will continue to function. I agree this has nothing to do with the arch/noarch mode but one has to have the log files multiplexed to get out of such scenarios.
