Hello everybody,

I am interested in mining association rules field

I have found some posted statements but I didn't undertand them. I need your help badly.

Just tell from where should I start?

Thanks alot

There is a tutorial using association rules for market basket analysis at http://msdn2.microsoft.com/en-us/library/ms345326.aspx

This is a good place to start.

Million records table

Hi everybody,
I set up a merge replication on Sql2K with one publisher/distributor
and 6 anonymous subscribers that run msde.
The db is growing bigger and bigger and i can't understand why.
I noticed that some of the MS_xxxxx tables are very large: in
particular one is 16.7 millions and another over 770K. Is there a way
to reduce/shrink these tables?
Thanks
Lorenzo
How many rows are being modified (inserted/updated/deleted) in the replicated
articles? I would expect this to be a similar order of magnitude to the
msmerge-contents, msmerge_tombstone tables. These tables will be
automatically cleared down during synchronization as part of the meta data
cleanup naturally run in merge by sp_mergemetadataretentioncleanup so
normally you don't need to do anything - the rows will be removed as they
reach the retention period defined in the publication.
HTH,

Hi Paul,
i don't know exactly haw many rows are being modified, but i can tell
you that the largest replicated table counts less than 130000 records
and i'm sure only a small part of these are changed/added/deleted
the msmerge_tombstone now counts almost 7 millions rows
i'm having some timeout troubles when i synchronize and i often get
the "can't enumerate changes" error
now i'm checking all my tables and indexes to see if some are missing
(the publication is partitioned with dynamic filtering)
thanks a lot for your help

that was a great idea, Paul
i found that there are over 5 million rows relating to a view that
returns 4800!
now i know what to investigate ;-)

Migration from DTS to SSIS

Hi everybody,

I would REALLY appreciate it if some had a link to a good tutorial about migration from DTS to SSIS, but without visual studio . net.

For example I need to use DTS package in sql server 2005 and execute them, I used migration wizard (SQL 2005) but it didn't work because i have in my computer sql 2000 et sql 2005 and the server name is PC2, however when i use the server source PC2 and the server destination PC2 an error message appear "server destination should be a sql server 2005 instance ".

help me please..

Thanks very much anyone response my question.

Moving to the SSIS 2005 forum from the SSIS 2008 forum.|||

If the connection is to a computer with both 2000 and 2005 on it, the 2005 install needs to be referenced by the server and instance name (MACHINENAME\INSTANCENAME).
