If you're not using data guard broker, at least consider it.

Ed,  

I use following query modified based on metalink note 861595.1 to add few columns for thread#:  

select arch.thread# "Thread",
 appl.first_time "LastSeqApp1sttime",appl.sequence# "Last Sequence Applied",
 arch.first_time "LastSeqRec1sttime",arch.sequence# "Last Sequence Received",
 (arch.sequence# - appl.sequence#) "DiffSeq",  round((arch.first_time-appl.first_time)*1440) "DiffMins"  from
 (select thread# ,sequence#,first_time from v$archived_log where
(thread#,first_time ) in (select thread#,max(first_time) from
v$archived_log group by thread#)) arch,
 (select thread# ,sequence#,first_time from v$log_history where
(thread#,first_time ) in (select thread#,max(first_time) from
v$log_history group by thread#)) appl
 where
 arch.thread# = appl.thread#
 order by 1;

Regards,
Sanjeev.

    I have a few questions regarding dataguard. We currently have DG running in a 2 node cluster, and a third server (non-rac)

    The primary, and physical standby run in the cluster. The LSB being on a separate server. (not in the cluster)  

    We are looking for ways to monitor the DG environment. We're creating some scripts to do so. Does anyone have any scripts they would recommend ? Is grid control a viable solution ?  

    Also, on system reboots of the cluster, how do you handle the startup of DG, specially on the physical and logical servers ? Do you modify the cluster scripts, or dbstart to accommodate this, or create something else ? I was unable to find anything on metalink.  

            Your response is appreciated.
