is there any way to check if the mirror is caught up to recent changes before issuing the failover command?

    When i try to execute the statement "ALTER DATABASE <DBNAME> SET PARTNER FAILOVER" , i am getting error stating that "the mirror server is not caught up to the recent changes, unable to failover" . After waiting for some time, it performs failover. Is there any way to check if the mirror is caught up to recent changes before issuing the failover command?

    Run ALTER DATABASE <dbname> SET PARTNER SAFETY FULL to synchronize the databases before failing over.

    Verify synchronization with:

    SELECT

    sd.Name,

    dm.*

    FROM

    sys.database_mirroring dm JOIN sysdatabases sd ON dm.database_id = sd.dbid

    i checked the mirroring state before issuing the failover command. It was showing "SYNCHRONIZED". But when i issue the failover command, i am getting an error tha says mirror is not caught up to recent changes. After waiting for some time and reissuing the command, failover is taking place
