Databases updating simultaneously - Microsoft SQL Server

RS200Phil

Hi,

I have managed to create a second copy of my "live" database, for
software testing purposes.

Inspecting the properties of the new database, everything seems in
order. The logical file name is the same, which I believe is fine, and
the physical database (and log file name) is different.

However, despite the fact that there is no application currently
accessing the "testing" copy, both databases are seemingly being
updated simultanously. I can tell this from the physical file sizes on
the server, which are identical, and growing at the same rate.

Does anyone have any suggestions why this might be happening - and how
I can stop it?

Thanks in anticipation!

Phil

It sounds funny to me that you can see the files grow. Autogrow events
on live databases should be rare events and not happen frequently. You
create them with a reasonable initial size, and then you preferrably
increase then while you have a maintenance window. Autogrow during
production should be avoided, as it could cause the database to be
inaccessible while autogrow is in progress.

To tell why your databases grow in parallel would require more knowledge
about your server. Here we are left to wild guesses. Maybe you set up
replication between the databases?

sp_who can tell you if there are any processes in the database at all.
You can use SQL Server Profiler to see if there is any action in the
server.

Which version of SQL Server are you using?

ODBC connection to V7 and V8 databases simultaneously

by: byrocat | last post by:

Up until now, I've been working with V& DB2 UDB databases, using Embarcadero DBArtisan as my GUI tool. I also have other tools that I use in my day-to-day job so running directly on the server via the CLP is not a viable option. I've just had a number of V8 DB2 UDB databases added to my task list. Of course #1, the old V7 DB2 ODBC client software doesn't connect to V7 databases.
