direct writes

Hi,
When running a job that inserts data into a particular table we are
seeing a significant number of direct writes against the tablespace
containing the table. This is the only
table in the tablespace and there are no other jobs running against the
table at the same time. The table contains no lobs or long varchar
columns so we cannot understand what is causing the direct writes.
Anyone any ideas ?
Regards,
John.

Just off the top of my head, aren't log writes counted as direct writes.
Direct writes, AFAIR are all writes that are non buffered, meaning thru the
buffer pools.
Inserts would have to be logged an cause log writes. If the logbufsz is
small, you could cause a lot of direct writes.
HTH, Pierre.

From what I've read in the docs, ado.net currently supports opening sql server ce tables in table-direct mode and performing Seek operations on them (using SqlCeDataReader), but not on the full-blown sql server. Is this (will this be) still true with ado.net 2.0 & sql server 2005?

Folks, I have a Javascript performance question that I might have problems explaining... In PHP, better performance can be obtained dealing directly with a variable, as opposed to an element in an array... Thus, if I have a programming routine that utilises $a several times, it is better to write the value contained in $a to something else, for example, $vartmp, and have my routine instead use this for its work... I believe

I added a linked server successfully; but the only tables accessible are only the system tables! I do have all the rights on both servers (Windows & SQL server). All the non system tables are designated as DBO. Strange thing is that I was able to access the non system tables only from the query analyzer (not from the SQL Manager tree) by using the following script:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
