Hi All,
I have a dillema that I created 2 transaction file before I started to
take log back. Now I changed my recovery model from simple to full. Do
I still need to keep my second transaction file? If I remove it would
it be a problem for my system and log back up?
If somebody responds me I really appreciate it
Regards

You can remove it if you like, but you should do it properly with
DBCC SHRINKFILE (EMPTYFILE) and ALTER DATABASE.

Let's see, then I would have to look up the exact syntax in Books Online,
since I don't know it by heart. As I said, use DBCC SHIRNKFILE with the
EMPTYFILE option, and then ALTER DATABASE with REMOVE FILE. Please check
Books Online for the exact syntax. There is also some good text that
explains what EMPTYFILE is all about.

What do you think is it good or bad to remove the second log file ?
what would you do keep the log file or delete it? Is it gonna have any
negative effect on my log back and its size?
by the way this is the code that you recommended
-- Empty the data file
DBCC SHRINKFILE ('Test1data', EMPTYFILE);
GO
-- Remove the data file from the database
ALTER DATABASE AdventureWorks
REMOVE FILE Test1data;
GO

The main reason for having multiple log files is to spread the load
over disks. Or handle the situation when the transaction log outgrows
its disk.
The log backup will not be very much affected of whether there are one or
two log files. The size of the log backup will depend on much is written
to the transaction log.
I can't really say whether you should keep the second log file, because
I don't know what your database is about, nor do I know the sizes of the
database or the log. But if the log grew, because you failed to back it
up, there is a fair chance that you by now have an over-dimensioned log.

I have the need to perform an atomic operation in two systems, a database and
an ftp site. The process is two step; 1. insert a row into oracle, 2. delete
a file from a remote ftp site. I need to make these steps atomic...either
they both succeed or both fail. Any suggestions on how I create a
transaction that bridges these two steps (systems) using C#?
Thanks in advance!

Hi,
We have created a SQL server 2000 database. We observe that the
transaction log keeps growing over time. We are now about to run out of
space. We have been periodically shrinking the database. Nevertheless
the size has increased. I would imagine that a transaction log can be
eliminated if we stop the database. Can that be done? Is there a way to
completely wipe off the transaction log?
Thanks,
