I'm running in archivelog mode (of course) under NT.

Every 10 minutes I issue a ALTER SYSTEM SWITCH LOGFILE, wait 10 seconds for archiving to finish, then start zipping the archlog(s) to send them across the country.

It would seem MUCH better to use ALTER SYSTEM ARCHIVE LOG CURRENT and not wait. Can I be sure that the archlog file has been totally written and any OS sharing locks released, before control is returned (ARCH being an asychronous process)?

(The answer ought to be "Yes" - but I can't find it anywhere).

TIA - DaPi
