I have just started trying to catch up my standby database and applying
the arcive logs.
Below is the alert log from the standby server. It apparently 'sees' a
few logs, copies them from the primary, applies them, then moves on....
most of the time. OFTEN I get long pauses when a fetch fails.
Why would a fetch fail? How can I improve the fetch rate?

Both servers are HP-UX11i running Oracle 9i (9.2.0.4). I get <1ms ping
times and ALWAYS get a good response using TNSPING. Ideas?
Thanks!
