Quick question. Is it a fair statement to say that using Oracle's hot
standby database allows you recoverability up to the last archive log, but
would NOT recover to the latest redo log (prior to a log switch). In other

Rich, no problems other than, the "performance" issue, if they
are hitting it hard and oracle lags in trying to post the logs to the standby

other than that it should be fine.

Actually there may be no problem at all. Your standby
database might be up to date, the last available archive log file has been
applied to your standby database and Oracle tried to apply the next archive log
file 'D:\ORACLE\ORA81\DATABASE\ARCHIVE\ARC00505.001 and did not find it, since
you
has log 505 made it over to the standby yet, you should start reading
the docs, if log 505 is not there yet, than that is the way its SUPPOSED
to work.

After getting all the archives properly, run a

So my standby is in managed recovery mode.
i was curious internally how does oracle send the archive logs across
from primary to standby machine(they are physically separate).
i know it goes via net8, does it do some internal fopen to write it out
and apply it, or am i way out in left field
never mind, i found it, the RFS(remote file server) process handles it.
