Applying logical logs

I have a production server in site A, and a contingency server at site B some miles away. Each night I copy an archive of the production server to site B and restore it. Using onarchive/ondatartr, the database server at site B is in "Fast Recovery" mode at the end of the restore. I leave it like this, because it retains the flexibility to (a) bring it online if it's needed or (b) copy subsequent log back-ups to site B use ondatartr to apply these, thus bring the database server up-to-date. I believe that you can't to this with ontape; the archive restore and log roll-forward must be done in the same operation. Am I right? It makes a difference because the database server is so large that it takes over an hour to restore. Thanks Neil Truby Chase Manhattan Bank Bournemouth, UK neil.truby@chase.com
