In what way this is used? Using this how we can avoid the query time out?

Please correct me if I'm wrong Mohan but I think the way this would be used is by inspecting the results and increasing the query timeout to a value greater than the max value of the results of your query. If the max value is extraordinarily high (minutes vs. seconds) then there are clearly other (presumably network related) issues.

Does this answer your question Priya

Hey , any body have query that will work on multiple subscriptions , this does not work on multiple subscription , i am looking like

publisher , subscriber , publisher_db ..

i tried below but it is working fine on one subscriber but i am looking if somebody can tweak it for multiple subscribers





SELECT distinct MM.Publisher as [Publisher Server],MI.subscriber as [Subscriber Server],MM.publisher_db as [Publisher DB],
datediff(mi, TT.publisher_commit,TH.subscriber_commit) AS [Latency From Publisher to Subscriber in Minutes],
datediff(mi, TH.subscriber_commit, (getdate())) AS [Time Difference in last Successful Transaction commit at subscriber to Current Time in Minutes]
FROM MSTracer_tokens TT(nolock)
JOIN MSTracer_history TH(nolock)
ON TT.tracer_id = TH.parent_tracer_id
join MSreplication_monitordata MM(nolock)
ON TT.publication_id=MM.publication_id
join MSsubscriber_info MI
ON MM.publisher=MI.publisher
join

(select max(tracer_id)s ,publication_id FROM MSTracer_tokens (nolock)

join
MSTracer_history(nolock)
on
tracer_id=parent_tracer_id
where
subscriber_commit IS NOT NULL
group by publication_id)xyz

on TT.tracer_id = xyz.s

Not sure if this is quite what you wanted, but you can tweak the query in the article to add in the name of the publication and the name of the subscriber's distribution agent by joining MSpublications and MSdistribution_agents thus:

select MSpublications.publication,
MSdistribution_agents.name,
MSTracer_tokens.publisher_commit,
MSTracer_tokens.distributor_commit,
datediff(ss, MSTracer_tokens.publisher_commit, MSTracer_tokens.distributor_commit) 'Latency bw Pub and Dis',
MStracer_history.subscriber_commit,
datediff(ss, MSTracer_tokens.distributor_commit, MStracer_history.subscriber_commit) 'Latency bw Dis and Sub'
from MSpublications
inner join MSTracer_tokens
on MSpublications.publication_id = MStracer_tokens.publication_id
inner join MSTracer_history
on MSTracer_tokens.tracer_id = MSTracer_history.parent_tracer_id
inner join MSdistribution_agents
on MStracer_history.agent_id = MSdistribution_agents.id

Hope this helps,
