Re: Clustering Performance Issues

Few things, 

Make sure the catalog.nsf, cldbdir.nsf, and the clubusy.nsf are clustered 
properly on both servers
and ACLs are correct. 

Also check the other replica stats

such as

  Replica.Docs.Added = 281155
  Replica.Docs.Deleted = 293434
  Replica.Docs.Updated = 1800535
  Replica.Failed = 586
  Replica.Successful = 515022

If you see a large percentage of replica.failed that could indicate a 
network or other issue.

Turn on Debugging, by doing "set config LOG_REPLICATION=1"

it will dump all cluster replica events events look for errors. 

12/08/2006 01:56:24 PM  Replicator added 1 document(s) to CLUSTER 
njmail11/BBBY mail\candrews.nsf from mail/candrews.nsf
12/08/2006 01:56:24 PM  Pushing mail/mwilliam.nsf to CLUSTER njmail11/BBBY 
mail\mwilliam.nsf
12/08/2006 01:56:25 PM  Replicator deleted 1 document(s) in CLUSTER 
njmail11/BBBY mail\mwilliam.nsf from mail/mwilliam.nsf
12/08/2006 01:56:25 PM  Pushing clubusy.nsf to CLUSTER CTSApps02/BBBY 
clubusy.nsf
12/08/2006 01:56:27 PM  Replicator updated 2 document(s) in CLUSTER 
ndsa980h/BBBY clubusy.nsf from clubusy.nsf


Share you results here on the forum, and maybe we can spot an issue. 

Good Luck, 

Sean

Walter, 

The queue depth is high, but I think it is because there is a deeper 
issue.  I can load more replicas, but not sure that is the ultimate 
solution.

What "Range" paramater are you talking about?  I am not very familiar with 

the AS400 or is it a Notes server/INI setting?

Thanks for the info.

Brian

  Replica.Cluster.WorkQueueDepth = 543
  Replica.Cluster.WorkQueueDepth.Avg = 179
  Replica.Cluster.WorkQueueDepth.Max = 721

Clustering Performance Issues






All,

We recently clustered our AS400 Mail server with a Windows Server.   It 
was on 6.5.4 and is now on 7.0.2. 

We are experiencing issues with Cluster replication.  I only have about 
1000 users and I have 3 cluster replicators running on each server.

The issue I have is that when a change is made on the windows server it 
comes across to the AS400 within about 2 seconds.  Going the opposite 
direction from the AS400 to windows it can take over a couple minutes for 
it to replicate.  I have had a ticket open with Lotus for over 2 months 
and no luck so far.  We have done the following....

1) Made sure that the NICs and switch were set to 100/Full Duplex.
2) Made sure that compression was not turned on on the clustered port.
3) Applied all the latest PTFs.  (we are on V5R3).

It is on the same network segment and switch so I am at a loss.  I have 
done clustering on 2 windows boxes before with several thousand users and 
not had this issue so I am guessing it is something on the AS400 slowing 
things down.

The Server Availability Index is really low....see below.

Any ideas would be GREATLY appreciated.

Thanks

Brian

Also even though they are on the same network segment should I force from 
the AS400 level a static route for the two to talk to each other.  I have 
all the appropriate INI settings for the clustering in place from a Domino 

standpoint.

Thanks

Also, have you included the Windows Server's host name and IP address in 
the local host table on the i5?
