We have developed a mostly-disconnected smart client app written in C# that uses MSDE as a local backing store. With the announcement of SS Ev, we attempted a port of our app over to SS Ev. The port went smoothly, however, the performance has been significantly (very significantly) degraded. Before we being our investigation into the cause of the performance degradation, I thought I might see if anyone has suggestions on where we should look for possible performance issues. Any suggestions?
Ok, a while back, probably a year or so I started moving to MSDE. At the time a read posts on the Web that said you could use the client tools from the SQL Server Eval to manage MSDE. Great! I thought.
But more recently I get the impression that using those tools in not allowed. Can someone give me a diffinative answer.
I really want to stick with MSDE and am having a hard time convincing the boss to shell out $9,000+ for SQL Server on my dual processor web server. But I need DTS, Job Scheduling, etc...
Now my boss has wind of MySQL and knows that it's CHEAP.
If I can legally use the client tools with MSDE than I'm fine, if not I dread going to MySQL.
I have a installation of MSDE MSQLSERVER on my machine, in this server i run a local database. The problem began when I uninstalled the msde sqlserver and reinstalled it. The program tha uses the database not are connecting, they prompt: "login failed"
I am trying to restore a database backed up using SQL Server 2005 Express Edition to a server using MSDE. I get an error 3205 "Too many backup devices specified...64 max..."
hello everyone, does anyone know some tipps or articles that descripe how the sqlserver 2000 can be improved? i have an application which displays newspapers. the text of the newspapers is saved in db. performance is ok but i have performance-problems when i do a fulltext-search.
1) hardware: p4 xeon double core, 2.4 Ghz, 2 GB Ram 2) number of articles in database: ~ 255.000 Records (betwenn 10 - 400 words each) 3) the database is indexed (i am searching with "CONTAINS" and not with the "LIKE"-keyword) 4) in my query i am searching in 3 columns (title,leadtext,content) 5) results (searching for one word, stopping after 150 Results):the time to get a result from database lies between 5 to 10 Seconds (Average: 6.77 sec)! this is the time only for getting the dataset from the sqlserver. the time of manipulating the dataset and binding it to my repeater needs about 15 milliseconds. using a sqldatareader didn't improve the performance. i got the same results. in future the number of records will be three to five times higher than now. i am afraid that then the user has to wait half a minute to get a result of 150 search hits. my questions: Are you having similiar results in your applications? Are this times acceptable? The SqlServer 2000 (professional) is installed in its default way with the default settings. Are they possiblities to modify this settings for improving performance? Where can i find info about that?
I really need some help here. I am having performance problem with SQL Server 7.0. I am using Visual Basic 6.0 as Front End.
I have the table with 34 columns. I have Clustered index on the table. Table contains more than 26 thousand rows at this point and it is growing very fast.
My problem is that when I connect to this table from my application(to retrieve data) performance is extremely slow. I marked that if I have few rows in my table than performance is not that bad. Please help...
Apparently you cannot go backwards. Once 2005 Express is installed, even removing it does not allow you to setup MSDE 2000 again. So there is no "trying it out" option.
Unfortunately, our software does not use 2005 Express. I tried it out, and now have a useless testing workstation that can't have MSDE 2000 installed again.
Any ideas on how to break the chain here are welcome.
I'm working on a VB.NET project where we are intending to use MSDE as ourback-end database. The actual number of users is expected to be low and Idon't have any concerns as to whether MSDE will be up to the job (most ofthe time). I'm aware that if we end up with lots of users connecting to oursite at once (which may happen as certain times in the year when people needinformation for deadlines) then the performance governor in MSDE will kickin and slow everything down.What I don't know is how do I find out whether the performance governor haskicked in?I would like to know how to monitor this so we can make an educated decisionas to when we need to migrate to a full version of SQL Server (if at all).Can anyone point me in the right direction for finding this out?thanks,Brian Cryer.
I have been testing one of our Apps under SQL 2005 Express and I am seeing a big downgrade in performance compared to MSDE on the same hardware. Has anyone else experienced this?
Hello, all, I started out thinking my problems were elsewhere but as Ihave worked through this I have isolated my problem, currently, as adifference between MSDE and SQL Express 2005 (I'll just call itExpress for simplicity).I have, to try to simplify things, put the exact same DB on twosystems, one running MSDE and one running Express. Both have 2 Ghzprocessors (one Intel, one AMD), both have a decent amount of RAM(Intel system has 1 GB, AMD system has 512 MB), and plenty of GB offree disk space. MSDE is running on the Intel system, Express isrunning on the AMD system. To keep things fair I use the exact sameDB's and query on both systems. The DB's were created on MSDE so Isp_detach_db'd them from MSDE and then sp_attach_db'd them to Express(this is how MS says to do a "side-by-side" upgrade, so it'sacceptable to do so). After fighting problems in performancedifferences in different situations I have narrowed the problem downto this:Executing a simple select statement with join clause on the databasesyields a difference in execution time that is quite great. Using theExpress Management program I can run the query against either system(MSDE or Express, the two systems are connected via crossover cable toeliminate any network problems/issues). When running the queryagainst the MSDE system (which is over the network) I consistently get<20 ms response times on the query. When running the query againstthe Express installation (which is in shared memory) I consistentlyget 700 ms or longer response times. Both times are for the TotalExecution Time.The query is simply this: select db1.* from db1.owner.tablename as db1inner join db2.owner.tablename as db2 on db1.pkey = db2.someid wheredb1.criteria = 3So, gimme all the columns from one table in one DB (local to theinstallation), matching the records in another DB (also local to theinstallation), where one field in the first db matches a field in thesecond db and where, in the first db, one column value = 3.The first table has a total record count of 630 records of which only12 match the where clause. The second table has a total record countof about 2,700 of which only 12 match up on the 12 out of 630.Even though the data is the same and I've done the detach and attach,and even done the sp_updatestats, the difference in execution time isremarkable, in a bad way.Checking the Execution Plan reveals that both queries have the samesteps, but, on the MSDE system the largest consumer in the process isthe Clustered Index Scan of the 630 record table (DB1 in my queryexample), using 85%. The next big consumer is a Clustered Index Seekagainst the other table (2,700 rows), using 15%.The Execution Plan against the Express system reveals basically theexact opposite: 27% going to the Clustered Index Scan of the 630record DB1, and 72% going to the Clustered Index Seek of the 2,700record DB2.I'm sorry to be stupid but I have this information but I don't knowwhat to do with it. The best that I can tell from this is that thisis the source of my problems. My problems are that on my currentsystems that my clients use the data is returned to them faster thanthey can click the mouse and that the new system (that is, when theychose (or are forced by attrition) to move to Vista and thus Express2005) the screen pop is like 1.5 seconds. This creates poor userexperience. Worse, one process I allow the users to do goes fromtaking 14-30 seconds to over 4 minutes (all on the same machine withthe same OS and version of my program, so it's not a machine or OS ormy app problem).Anyway, I hope someone can shed some light on this now that I've paredit down some.Thanks in advance.--HC
Hi, I'm using Visual Web Developer Express and Management Studio Express, and my web site is on a shared web hostΒ΄, running SqlServer2000. I'm looking for software that enables me to monitor the server, but is it possible? The only apps I've found (and downloaded and installed and unistalled) so far need administrative rights to the server so they won't work on a shared web host. All help would be welcome! Thanks in advance, Pettrer
I have a performance related question about the DTS package in sqlserver 2000 which i have developed We have developed a DTS package which will migrate a view 'ATTRITION' from Sqlserver 2000 to an Oracle database.The design of the package is as follows First step: It checks for the existance of the table 'ATTRITION' in oracle database, if table 'ATTRITION' is not there it will create a table called 'ATTRITION' in the oracle db.If the table 'ATTRITION' is already present in the oracle db,then the table is truncated.
Second step: The view 'ATTRITION' is migrated to Oracle table 'ATTRITION'. For the migration, i have used a connection object which connects to sqlserver 2000 and for oracle connection i have used another connection object 'Microsoft ODBC driver for oracle' and i have joined both the connection objects with 'Transform data task' task which maps one to one from sqlserver 2000 where view 'ATTRITION' exists with oracle database where Table 'ATTRITION' exists. Roughly i have around 65000 rows in 'ATTRITION' view of sqlserver 2000 which needs to be migrated.When im running the package on my system it takes around 4 minutes to migrate all the rows but when im running it on the server it takes a lot lot of time more than 1 hour.
The view definition im using has more than 10 tables joined together.But if its a problem of query used in the view,and if i run the view seperately it quickly displays the data hardly takes 1 minute. and even if i run the package on my local pc it doenst take much time.Now my confusion is why its taking soo much time on server.If i create a indexed view then will it solve my problem.Please suggest... Thanks in advance
Recently we have migrated our application from MSDE 2000 to SQL Server Express 2005(SP 1). This has significantly reduced the performance of our Windows.NET application which is developed using C#.
For example : While logging in to the application two databases are being attached.
Time taken in MSDE: 16 secs
Time taken in SQL Server Express 2005 : 58 secs Also note performance is degraded for normal screens where data is retrived from database using inline queries.
Questions:
1) Is there any special(optimum) configuration(installation parameters) while installing the SQL Server Express 2005 setup?
2) Is there any query optimization to be done w.r.t SQL Server Express 2005 ?
We highly appreciate any help towards resolving the above problem. Regards, Sasi
Does anyone know how to how to performance case-insensitive search onXML data type in SQLServer 2005? Or I have to convert all the xml datato lower case before I store it?Thanks in advance.John

I'm not sure if it's the setup I did wrong, but I can't seem to get my text datatype in my database to store more than 900 characters. I'm trying to setup a news database for my website, which will populate the information into a datagrid. To test, I manually added a news item in the database through the visual studio 2003 gui. I immediately noticed a problem as the I was getting an error after a long news item saying:
"The value you entered is not consistent with the data type or length of the column, or over grid buffer limit."
I couldn't find anthing to set the buffer limit and the datatype is "text" filled with simple text in the column. As a further test, I simply entered 12334567890123... up to 900 characters and still recevied the error.
I would appreciate someone leading me in the right direction on this one.
I am trying to change the computer name of a machine running MSDE but I get an error when SQL Server starts. With regular SQL when I change the name of a computer I re-run setup and setup fixes this problem. MSDE can only be installed from unattended mode so I cant rerun setup and fix the problem.
My question is "How do I change the name of a computer running MSDE with out reinstalling MSDE"
We currently have the problem, that all our machines are produced with the same name and afterwards the name is changed. So we have the problem that the checksum key for the MSDE isn't valid anymore. As MSDE can only be installed from unattended mode so I cant rerun setup and fix the problem. Does anyone know a solution for this problem ?? A program recalculating the cheksum ??
I'm not sure if this is the correct forum for this this question but I'll give it a shot.
The only db development that I have ever done is in MS Access. I have a project at work that is being accomplished in VB and I need a db engine to use as the back end. Visual studio came with a copy of MSDE. Is this tool worth using or should I invest in mySQL? Are there any advantages to using MSDE over mySQL?
We have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?
Here is the class:
Code Snippet
using System; using System.Collections.Generic; using System.Text; using System.Net; using System.IO;
namespace Predict.Services { public static class Foo { public static string GetIntradayQuote(string symbol) { string returnQuote = "";
HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("http://data.predict.com/predictws/detailed_quote.html?syms=" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));
StreamReader streamReader = new StreamReader(response.GetResponseStream());
returnQuote = streamReader.ReadToEnd();
streamReader.Close(); response.Close();
return returnQuote; } } }
When I run call it from a console app it is fine.
I compile it into a dll and then create the assembly and function as follows:
Code Snippet
drop function fnTestGetIntradayQuoteXML_SJS
go
drop assembly TestGetIntradayQuoteXML_SJS
go
create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS
go
CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote
go
declare @testing nvarchar(max)
set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')
print @testing
When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?
I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.
I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?
The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.
I'm chasing after a documetn that was available on one of the Microsoftwebsites that was titled somethign like "MS SQL Server Best Practices"and detailed a nyumber of best practices about securing the server.Included in this was revoking public access to the system tableobjects.Can someone post the URL where I can pick this up, or drop me a note oncontacting them for a copy of the document?
I have an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000.
Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express? The app would still be using the sqlserver 2000 jdbc driver to try and make the connection.
If that is a possibility, what can be some differences in the configuration? Previously with 2000 the config information I entered is:
server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS"
DB name: name of db instance
port: 1433(default)
user and pass.
My attempts so far results in
"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket."
and
"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unable to connect. Invalid URL."
I have an SQLServer Mobile database, and I would like to know if there is a way to upgrade it to SQLServer 2005 (.mdf) database. My database has no records in it, just the structure (tables etc). What I am actually asking is if I can create automatically a new SQLServer 2005 Database with the same structure as my existin SQLSErver Mobile database
I am in the process of planning a server upgrade to sql2005 x64.
I created 2 linked servers: one to a SQL2000 sp4 server and one to a SQL7.0 SP3.
I have the following error when I query the linked servers. OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "Unspecified error". OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "The stored procedure required to complete this operation could not be found on the server. Please contact your system administrator.". Msg 7311, Level 16, State 2, Line 1 Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "IVDM2K". The provider supports the interface, but returns a failure code when it is used.
I am aware of KB 906954. http://support.microsoft.com/default.aspx?scid=kb;en-us;906954
I applied the instcat.sql on the SQL2000SP4 server and my linked server issues for that one are gone.
However, I ran the instcat.sql script on the SQL7.0 sp3 server and the linked server is still giving me an issue.
Hi, I am new to SQL Server 2005. I tried connecting to my local machine by using my machine name as Server name and then tried running the following query: SELECT * FROM SYS.Objects. It gives me following error: Invalid object name 'sys.objects'.
Whereas, if I connect to my local machine using mahcinenameSQLEXPRESS, then the above mentioned query runs fine.
Why is this difference? What is the difference when I login in these 2 different ways. Any help would be appreciated.
