I have two clustred Domino Servers running Domino 8.0.1 om Windows 2003 Server. The size of the databases on the 2nd server is much larger than the size on the 1st server, in a lot of cases they are 75% bigger, for example on Server1 I have a mail database of 4.2GB but on Serevr2 it is 7.5GB. There is no shared mail configured on either server.
Any suugestions as to why there is such a difference in the sizes?
Subject: multiple replication?
does the database replicate with any other servers? and is it possible that it’s being replicated with more than one server at a time?
see http://www-1.ibm.com/support/docview.wss?uid=swg21174380
Subject: You might have it there
The server with the larer sizes only replicates with te one server, in fact there are only two Domino servers in the environment anyway.
It is possible that multiple replicators were running when the initial replicas were taken.
I will delete one of the databases with the issue, it is not every single database on the server but most of them, and take a fresh replica. If it comes out at about the right size and stays in line I will assume this was the cause.
Thanks.
Subject: Re. : index views size
Hi,The difference is the size of the indexes of the views.
When you use a db preferentially on one server, this server will calculate index for dispalyed views. If you don’t open this same db on the second server, these indexes will not exist.
Within the Domino Admin, go to the files tab, and right click on your db file for displaying index views sizes (Manage views)…
Subject: Thanks for the suggestion
I had already checked the view sizes. The larger databses are the ones not being used by the users, the database in my example which is 4.2GB on one server and 7.5GB on the other server only has 44KB of view indexes on the 7.2GB version of the database!
Subject: ‘shot in the dark:’ No compact was running on one of the machines?
I am not too much into clustering and could be wrong.
I’d think I would compare
a) Number of docs in Databases
b) Number of docs in All document views in Databases
(I have historically actually seen b) to be more satisfying numbers when tracing down Replication Problems *) than a).
If that numbers fit, and you want to go further, do a File-database-new copy from both servers, don’t open up the result and compare the file size (+a) + b)
') generic Replication Issues over 20 out of more than 200 Servers in a huge environment but not cluster replication. Compairing b) systematically, I got ahead of both, Endusers responsible for the data and the admins responsible for the replciation. This was a while ago (late R5 cycle). Sad but true, the kept on fixing without tracing down the root of the problem - I am still wondering if only the servers times kept being more or less out of sync for a long time
Subject: Compact is running on both server
Both servers have the compact task running each eveing with the -B option to reclaim unused space. Both replicas showing 99% usage in the database.
I have already checked that the number of documents in each replica are the same and they are. I have not looked at the All Documents view but will do, however I guess for each pair of replicas the amount of documents will match as the total amount of documents shown on the database properties matches for each set of replicas.
I have only looked at mail databases at the moment. I will compare the application databases also.
Subject: Hm, or a replication without attachments (larger than 40 KB Richtext fields)?
And this is not Daos enebled 8.5, either?
Subject: Not DAOS
Both servers are 8.0.1 so not using DAOS.
The server with the smaller database sizes was the original Domino server, the server with the larger database was introduced later and clustered with the original server. The databases on the 2nd server (i.e. the ones with the larger sizes) were replicated from the original server, therfore if only partial documents were being replicated then the 2nd server would have the smaller size.
All users are configured to use the original server as their mail server and would only use the 2nd server during an outage of the original server. As far as I know this has not happened yet.
Thanks for all of the good suggestions and keep them coming.
