Database Mirroring

If I take a full backup of the Principal
and for example take all log backups including the last log backup
and then restore them on the mirror
Do I leave the last t-log backup in the no recovery mode
and if so then how about the t-log still populating with data on the principal but
not the mirror how does sql synchronize the mirror properly if you cannot
restore the last t-log because it is being written to at the time you are setting up the
mirror

Any clarification as to how the synchronization process with the last t-log actually works would be greatly appreciated

Thanks in advance

Hi, in database mirroring only one database (principle) can be in operational stat and mirror database is in operational stat.
Reason to restore last TL backup with no recovery is that it will not accessible to user but accessible to principle database. Every time if a transaction is executed on the principal is sent first to mirror for commit if it is configured with synchronous. Transaction log is sent to mirror and restore in no recovery mode.
