Performance Vs File System
Nov 8, 2001
I am developing a new application and am trying to find the best way to deliver XML documents to the app. Here's the scenario: each set of xml docs will have a unique identifier. The app needs to retrieve a known xml doc by using this identifier. So the dilema I am having is as follows: I could create a folder for each identifier and load the xml docs relevant to each id into the folder. For the app to retrieve the document, it would simply construct a file path and the windows B-tree search would find it and return it very quickly. Alternatively, I could create a table with a primary key that stores the unique identifier, cluster it, and store the xml in a blob field.
Does anyone have any experience, references, or thoughts about which would be the best way to do this? I am an avid database developer and the app will be using sql 2000 anyway, however it seems in this situation the database might not be the best option in terms of speed, performance, and resource useage. Thoughts?
Thanks,
Mike

Hi,
I am developing an editorial system(MS-SQL). There are a public part(frontend for reader) and an editorial part (backend for editor, admin,...).
The public part of system will be used approximately 1000 acesses/s.
A possible solution:
I solve whether I have to use two databases:
1.DB all data
2.DB with data for frontend
acesses...............trigers
--------->2.DB <----------1.DB
or more of databases or else?
The purpose is, a reader should have good response that the reader don't wait.
Could you give me any advice ?
Thanks

Hi,I am starting a new job next week. Part of what I am required to do isa "system diagnostic" on a SQL Server 2000 box to determine what areascan use improvement - this would include configuration settings,backup/recovery, sql tuning, etc... and anything else I may not havementioned here!What I need is a thorough and systematic approach to doing this. Cananyone please give me advice, or point to a FAQ or other links thatdiscuss this. I am running out of time.THANKS MUCH

I just wanted how we can find the system performance without using tool like performance monitor or profiler.
I just need the query like equalent to peformance monitor for see the systmem status of CPU ,IO ,Memory and etc..

I 'inherited' a group of SQL Server server class machines. They aretrue server technology but the disk sub-systems are lacking. There isone hot-swap backplane that all the drives share (with one SCSIchannel) thusly even though there are three logical drives (composedfrom 6 to 8 hard drives), they all go through one channel. This iscreating a performance issue that is noticable and can be seen invarious performance counters that Microsoft recommended one shouldmonitor in terms of disk I/O. For a cheaper 'fix', I can add aseperate two drive bay (with its own SCSI channel) with mirroreddrives. I would then mostly likely place the transaction log files onthis new channel. Or I could place the indices filegroup files onthis new channel for DBs with mainly searching going on (not muchupdating). If I went this route I would be leaning towards thetransaction log move since the second method would require me movingDBs around quite a bit. Any input on this solution (besides spendingmore money)?What I would prefer to do is get a better server class machine or addan external drive bay solution (not a SAN). I would try to get threeor four SCSI channels in the new hardware to split the differentfile/filegroups out (i.e. transaction logs files, data filegroup,indices filegroup, etc.). My only concern here is: would this moreexpensive solution be worth the money? As far as replacing servers, Ihave only two kinds of experience...replacing somewhat underpoweredservers with slightly less underpowered servers and replacing overkillservers with even more overkill servers. In both cases, the disksub-systems were fairly equivalent from the old system to the new one.Will going the three/four channel route really get data moving along?We have one server in particular that hosts a database (one of many onit) for a web application that gets decent traffic (it is a privatelogin based system for internal use and external use by our clients'agents). Periodically throughout the day, there are 2-5 minute burstswhere performance slows to a crawl. I want to spend more timeprofiling queries and such before recommending we spend more money,but the folks I am working for want quick results and there is quite abit of stored procedure logic to profile and investigate. I know thedisk sub-system is definately in need of an overhaul, but I would liketo get an idea of peformance gains from adding either one additionalchannel over the existing single channel as well as going thethree/four channel route over the existing single channel setup.Any information would be greatly appreciated.Regards,Tony

Summary: Started replication April 1 of 4M xact / day publishing system to subscribing system.
Performance was good. Latency was ~ 5-7 seconds.
May 10 we noticed that the DB was behind (latency was 12 hours).
All performance counters seem good with the exception of the disk.
. Performance spikes are 8 minutes apart and last from 30 - 60 seconds.
. During this period, Disk % Busy (1 - Disk % Idle) is 100%
The publisher DB publishes about 50-52 xacts/sec.
Rate of distribution (distribution DB to Subscriber DB) is ~ 47 xacts / second, so latency is increasing (currently at 33 hours). Previously my Subscriber system's "capacity" was 150 xacts / sec.
I know this because several weeks ago, the network went down, we were 24 hours behind.
When the network came back up the replication subscriber system was able to catchup at around 150 xacts / sec, or 3X the production system rate.
What has changed between then and now? Not much. We did install Tivoli Service Manager (IBM's backup system) a couple of weeks ago. It seems to run fine on a nightly basis, but I don't see any periodic heavy Disk I/O from that. Just to be sure, I've had them shut the TSM services down just to be sure.
We've also eliminated all extraneous processes other than those I need for performance monitoring (there was a RTVscan, virus scan process).
I've eliminated Autogrowth's as an issue as I've bumped the growth so that they are very infrequent (several days at this point. When we resolve the problem, I'll dial this down to something more reasonable.
My disk configuration is not ideal I realize (single Raid-5 disk with 3 partitions), however, this has not changed in the 6 weeks.
Thanks for any help on this!

Hi,
I am trying to write a table-valued function in SQL Server 2005 (SP1) to return all active directory groups a user belongs too, using managed code (VB.NET).
Testing the code with a simple winform I get the list of groups in about 0.4 seconds. However the table-valued function takes upwards of 17 seconds to run! Is this normal for managed code in SQL Server?

I'm copying files to a folder with the naming convention as follows in the source folder:
CM_ABC_MY_TEST.txt
In the destination folder, this filename needs to appear as:
CM_XYZ_MY_TEST.txt
In my File System Task, I'm pretty sure I'm going to need an expression with a replace, substring, etc. But am having a hard time nailing down the exact syntax.

Does anyone know how to do this using variables? Everytime I try it, I get the
Error: Failed to lock variable for read access with error 0xc00100001.
I also tried it writing a script and still the same error. If I hard code the values into the variables it works fine but I will be running this everday so that it will pull in the current date along with the filename. So the value of the variables will change everyday. Here is my expression:
@[User::Variable] +(DT_WSTR,4) YEAR( GETDATE() )+"0"+(DT_WSTR,2) MONTH( GETDATE() ) + (DT_WSTR,2) DAY( GETDATE() )
The result:
C:Documents and SettingsmroushDesktopOSU20060818
the 20060818 part will change everyday ie.(tomorrow will be 20060819, next day 20060820 and so on.)

I am having an issue with the File System Task.
I was wondering if there is a way to 'Move File' with the File System Task inside of a For Each Loop container but to dynamically set the Destination path variable.
Currently, this is what I have:
FileDestinationPath variable - set to C:TestFiles
FileSourcePath variable - set to C:TestFiles
FileNameAndLocation variable - set to blank
For Each Loop Container €“ Iterates through a folder C:TestFiles that has .txt files in it with dates in the file name. Ex: Test_09142006.txt. Sets the file path (fully qualified) to the Variable Mapping FileNameAndLocation.
Script Task (within For Each Loop, first step) €“ Sets the FileDestinationPath to the correct dated folder within C:TestFiles. For example, if the text files I want to move are for the 14th of September, it takes FileDestinationPath and appends the date folder to the end of it. The text files have a date in the file name (test_09142006.txt) and I am picking this apart (from FileNameAndLocation in the For Each Loop) to get the folder date. (dts.Variables(€œUser::FileDestinationPath€?).Value = dts.Variables(€œUser::FileDestinationPath€?).Value & €œ€? Month & €œ_€? & Day & €œ_€? & Year & €œ€?) which gives me €œC:TestFiles 9_14_2006€?.
File System Task (within For Each Loop, second step) €“ This is where the action is supposed to occur. I want it to take the FileDestinationPath and move the FileNameAndLocation file (from the For Loop) into this folder for each run.
Now as for my problem. I want this package to run everyday but it has to set the FileDestinationPath variable dynamically according to that day€™s date. Basically, how do I get this to work since I can€™t hard code the destination path variable from the start? I have the DestinationVariable on the File System Task set to the FileDestinationPath variable, after the script task builds it. However, using FileNameAndLocation as the SourceVariable on my File System Task tells me that the €œVariable €œFileNameAndLocation€? is used as a source or destination and is empty.€?
Let me know if I need to clarify further€¦...I may be missing something very simple. Any help would be greatly appreciated!

I am able to run SSIS packages as SQL Server Agent jobs with a Control Flow items "File system task", if I move a file (test.txt) from a drive (c on the server (where SQL Agent jobs run) to a subdirectory on the same drive. But, if I try to move a file on a network drive, the package fail.
What I can do to solve this issue.

Historically I've always written a VB script to copy a file from a sharepoint library. I don't like this method because I have to input a username & password in the script and maintain a config file.
Yesterday I was playing around with using a file system task. The sharepoint file has a UNC path so why not? I created a simple test package with a single file system task that copies the sharepoint file (addressed via UNC) to another network location. Package runs fine locally.
I try running on our utility server but am getting a "The file name [SHAREPOINT UNC PATH] specified in the connection was not valid" error. Package is running with a proxy on the server and the proxy account has the same permissions to the sharepoint site (so far as I can tell) as me.

I have used the copy database wizard, but I realized I had forgotten to shrink the transaction log file. So I canceled the wizard. My database, detached by the wizard, has now disappeared. The mdf file is still there, but when I try to attach it manually I get the "create file encountered operating system error 5 while attempting to open the physical file..." error.
Any way I can recover it?
Thanks.

I have created a File System task which is contained in a Foreach Loop Container. I have .bak files that are populating a directory from a maintenance backup plan.
There is a point where I need to delete the .bak file's after I've zipped them all up.
How do I set the SourceVariable to read through the directory and pick up just the .bak file's in the directory to delete.

I am facing a problem on a server which has raid 5 solution (3 disks), the raid controller went down 2 of the disks were off in the Bios.
We added the 3 disks to a different server identical in brand and architecture, the raid controller was able to reconfigure the virtual drive H:.

Hi
This should be incredibly simple and easy, but I can't find any examples of how to do this.
I just want to make a File System Task move a file, and have the destination be filename + date and time. For example \serversharefilename02072007.txt
What syntax do I use in a variable to make this work?

Ok so I have some dynamic sql to delete a file that is created via sql earlier on. It is to provision a copy of a database to an instance on link server. Everything works great and the files used to delete. Now, with no code changes it is throwing a syntax error. I do a print of what the dynamic sql is creating before executing and then I copy / paste what was generated into command prompt and guess what!! The file deletes.
Here is the result on screen:
@DeleteBackupFileStatement: DEL adas16.clients.advance.localwip$AvionteAP_Template_893.bak /Q
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near ''.
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near ''.
Here is the code that creates the statement:
SET @DeleteBackupFileStatement = NULL
BEGIN
SET @DeleteBackupFileStatement = 'DEL ' + LTRIM(RTRIM(@BackupFile)) + ' /Q'
END
PRINT '@DeleteBackupFileStatement: ' + cast(@DeleteBackupFileStatement as varchar(400))
BEGIN
EXEC adasdb.master.sys.Sp_executesql
@DeleteBackupFileStatement
END
END
The value of @BackupFile is simply the path of the file with the file name, everything in the prepared statement with the exception of DEL and the switch at the end.

Hi All,
I have a source files folder where the files generated everyday.
My goal is pick the latest file and copy this single file to another folder.
I used the Foreach loop container and got the latest file and stored the file name to a varible i.e. LatestFile
Then i want to use the File System Task to copy this to the destination.
On the beginning, I could not setup the Latestfile since I don't its name then, so when I setup the Source Connection property of the File system task, it is not allowed to leave the SourceVarible as blank!
Any suggestion?
Thanks

I have the following directories
\servershare
\serversharearchvie
I have a for each file loop and inside it a data flow that pulls from one of the flat files in the directory and then a file system task. If I choose the "Move File" option in the file system task to move the file to the archive directory, it fails with an access denied message. The access denied message occurs after a message saying file was successfully deleted. I am running this from BIDS right now and my local user can write delete etc in both the above directories. However, if I do a "copy file" in the file system task it seems to work. I think what is happening is it is deleting the file first and then trying to move it, but it no longer exists because it has been deleted--is this possible? Is this a bug of some sort?
For now I am going to workaround by putting in another file system task that deletes the files after they were copied and see how that goes, but would prefer just to do the "move" option.
Thanks,
Kayda

I'm having trouble working this out in SSIS. I am trying to use a File System task to rename a file using an expression so that file.zip will be renamed to filemmyy.zip at the end of every month (for instance this month would be file0506.zip).
I am using the destination expression variable. But I'm not sure what to put for DestinationConnection. It seems to want a file name, but the file name is going to be variable, so I'm not sure what to put.
Any ideas?

Hi All,
I am having a problem using the file system task, what I am trying to achieve is to move a file after it has been processed . I am using a For each loop container to process bunch of files but I want to remove the files that have been processed after every loop.To achieve this I added a File System Task after my data flow task and was using the same variable used in the for each loop container as my source variable but the package is not being validated and is gives the following error
"variable used as the source or the destination is empty"
Appreciate your help

I have a File System Task that uses variables to resolve the destination and source paths of a document. When I select the 'copyfile' operation...the document is copied from the source to the destination without error.
However when I change the property from 'copyfile' to 'movefile' I get an error and the document is not moved.
The source and destination variables contain a valid file path name since the copy commmand is working as expected. However when I alter the properties of the File System task to move the document. I get the following error:
Could not find a part of the path 'G:CommonInformation SystemsDropFilesrtNRT_ConfirmationOrder Confirmation Report_11062006.xlsOrder Confirmation Report_11062006.xls
It seems a little nonsensical since the document file paths are valid when performing a copy. For some reason the error log is showing that that the file path is the document name "Order Confirmation Report_11062006.xls" and adding it twice to the the directory path called "'G:CommonInformation SystemsDropFilesrtNRT_Confirmation" as you can see in the above error message.
To replicate the 'move' action...I added an extra File System Task that deletes the document once the copy has been performed. I would like some insight into why this doesn't seem to work.
Thank you.

Anyone reading XML disk-files into SQL Server?
I have a process that I may want to do this with.
It would be a stored procedure that would read the XML attributes into 2 tables, the number of attributes could be 1-N, so I thought XML would be a good choice. Also, one of the attributes could be up to 4000 characters. I think this may limit our options, can 100-150 4000 character strings be passed in a standard call to a query/proc in SQL?
Currently the client application makes round-trip network calls to save upwards of 100 pairs of data. 1 header row, and many detail rows. All within a transaction.
I think If we move an XML file to the SQL box, then do all the import/save work on the "Server" side it would be much better. Cutting the transaction time down a lot by not doing so many round-trips at network speed...
Thoughts?

Hello all,
I've been asked to build a .net web application, where users will be able to upload, search and view images. There will probably be about 2000 - 10000 users who will upload and view photos each day.
Each image that is uploaded, is saved as a thumbnail, a small image, and the original. So considering the possible amount of data being uploaded, stored, searched for and viewed, whats the best way to store the images? Database or File system? Whats would be the fastest option for a web application? Should I even be looking at a different solution?
cheers!
