Change Detection/Rollback Required
Jul 28, 2007Hi
My table’s data is deleted by unknown person.
I can detect some thing about it i.e. user name, time, etc of this event?
Is there any way to rollback changes though logs?

We have latency in trouble shooting the deadlocks and causing blockings more on our critical Production server.

Torn Page Detection
Sep 14, 2000Anyone working with databases with this option turned on? How does it affect performance?
View 3 Replies View RelatedTorn Page Detection
Jan 7, 2005Hi, We recently had one of our drives (RAID5) replaced because of failure. This has resulted in a torn page being detected on one of our smaller SQL 2000 databases. We have one or two larger SQL databases (30-70GB) on the same drive amongst several others and are now concerned that we may have a problem with these databases also. (The original torn page only came to light when a query was run on one of the tables). Is there anyway I can run a procedure on each of the databases to find out if we have any problems with torn pages? I obviously don't want to restore the databases as this will take a substantial amount of time that we just don't have at the moment. Any ideas that could put our minds at rest would be much appreciated.
Many thanks.
Torn Page Detection
May 22, 2007I want to switch this setting off on all db's - that's easy.
But I presume that means the problem could occur without me knowing for weeks (maybe due to a defective disk driver). So is there a way I can schedule a maintainance task that will check for this problem out of hours? (Maybe by switching the DB option on for a while and then back off? If you switch the option on, does it check the whole database? Or does it just do checks during the actual update?) Hopefully there is a better way than that to do it...
Also, am I right in saying that CHECKSUM is new to 2005?
And what do you guys use: Checksum, Torn Page Detection or None?

View 1 Replies View RelatedClustering For Anomaly Detection
Mar 14, 2008Hi,
I have been trying to use the Clustering algorithm for Anomaly Detection, but it has been quite difficult to get correct results for PredictCaseLikelihood.
Using a very large number of clusters helped, but there are other problems.
The algorithm does not take into account all the columns in my nested table, but only uses Exists/Not Exists for the nested table key column. In my case the nested table contains also a column with a count of key attribute.
I am about to abandon the Sql Data Mining.
Does anyone have more insights into tuning the Clustering algorithm for anomaly detection?
Thanks

Turning Torn Page Detection ON
May 7, 2007Are there any issues turning this ON?
I have inherited a database which started life under SQL 7 (where Torn page Detection was OFF by default), and I'd like to turn it on. Will this reshuffle all the pages to make room for the extra check-sum, or is that stored in a single block somewhere else such that it can easily be added?
Is the change going to block access for long? (DB = between 2~5GB)
Thanks

Is It Possible To Disable Poison Message Detection?
Aug 3, 2006Hi,
I'm using the Service Broker to parallize my processes (I know that the Service Broker was not designed for that purpose), however it's working quite well.
I use the broker procedure to start procedures which all process all a part of the workload. When the procedure fails because of a lock timeout (or for that concern, for whatever reason), I rollback the transaction (which also roll back my message received on the queue so that it can be retried at a later time.). And this is where my problem lies, if there are 5 sequential rollbacks of messages then the poison message detection kicks in and disables the queue, stopping all the processing. :(
Is there a way to disable poison message detection? I have implemented my own stop-mechanism through a counter system on a per sub-task system so if I could disable poison message detection that would be ideal.
If this is not possible is there a way to turn the queue back on automatically so that it will continue processing the messages on the queue?
Cheers,
Peter.
IIS Detection On Vista: Where's My Windows Authentication Option ?
Mar 3, 2007I am trying to install RS on Vista. I notice that the list of IIS features to turn on, listed in the KB article and blog entries, mentions a "Windows Authentication" IIS feature to check under Security. I don't have that (although I have one labeled "Basic Authentication") -- I'm on a "workgroup" computer at home.
Does this mean that you simply can't install RS on Vista unless you're joined to a domain? Thanks,

Torn Page Detection And Auto Shrink: Performance?
Feb 16, 2006Hello everybody,First: SQL Server 2000 sp3a, HP cluster server, MS 2003 server,database recovery model simpleTorn page detection:When I have this option turned on, processes conected with updating andwriting in database, was MUCH more slower, than if I've this optionturned off.It seams to me, that when this option is turned on, the sqlserver ismuch more slower by any operation connected with writing, than withoutthis option.This option is required for ensurance, that the data are writtenproperly on the media.My question is:if I have my database running under cluster, with RAID hd system, whichcontains write cache, with additional checking, that the data will bewritten correctly, is it necessary for me to keep this option turnedon?Auto shrink:When it is turned on, does it affect performance?Personaly, I don't think so, but somebody is insysting on it, and Iwould like to have an information from independent source about that.Best regardsMatik

SQL Server SP2 Command Line Upgrade Switch And Express Version Detection
Mar 9, 2007Our application installation setup needs to be able to detect:
Is SQL Server 2005 Express Installed?
If false, run the SP2 Installation
Is SQL Server 2005 Express or SQL Express SP1 Installed?
If false, run the SP2 Installation with Update Switch
Is SQL Server 2005 (not Express) Installed
If true, abort installation with a mesage.
Can you direct me to some documentation about testing for these environments or just if someone has some scripts that will run in InstallShield, that would be great.
ALSO, can you direct me to information about using the command line update switch for the Express SP2 Installer?
Thanks.
