Sql Server Running Slow
Mar 2, 2004Hi,
Our main production server has started running slow, it is a dual zeon thingy with plenty of ram so hardware is not an issue.
Basically a service connects to the database and executes a few stored procs, the only way I can get the system up to speed again is to recompile one of the SPs but that is only a temporary fix.
Anyone had a similar thing?
Can anyone give me help on performance tuning in SQL server 2000.
Thanks

SQL Server Running Slow On A High End System
Mar 7, 2004I have about a 447 MB SQL server 2000 database on a desktop PC acting as a QA server. The hardware specs of the QA box are as follows:
CPU: P4 2.4 GHz
Memory: 1GB
Drives: 80 GB IDE
I recently purchased a Dell PowerEdge 2650 server to act as the staging box. The staging box has
CPU: P4 2.4 GHz
Memory: 2GB
Drives: 40GB SCSI, mirrored
I made a backup of the database on the QA box, and restored it on the staging box. Yet when I run something as simple as a select query (select * from <table>), the less powerful QA box is faster.
I figured maybe the statistics are different on the staging box. I ran dbcc showcontig to make sure the statistics were identical. Also ran RedGate's SQL compare and data compare to make sure everything was identical.
I figured maybe the query optimizer needs to be tweaked. I recreated the indexes and updated statistics on the staging box. The queries actually got slower as a result.
I thought maybe SCSI drives are slower. Tried breaking the mirror on the staging box. No luck. Put the mirror back in place, ran a test where I copied a large folder from one directory to another on the staging box. Repeated the same test with the same data on the QA box. The staging box was more than twice as fast than the QA box.
It doesnt appear to be a problem with the query, adjusting memory in SQL server has not effect, both boxes are using SQL server 2000 SP3, why is the bigger machine running queries hundreds of milliseconds slower than the smaller machine? Any help will be appreciated!

DTS Running Too Slow
Aug 8, 2000I have a dts job set up to transfer 550,000 records from a dbf file into a sql server. If I just let it run, there is a 9-10 minute delay, then it starts. If I try to schedule a job, it fails completely. I looked up ways to get it to execute quicker, mainly going to the advanced tab of the transform arrow and making the inserts 1000 at a time, the table locked, turning constraints off. Any advice on how to speed it up or why the job is failing?

View 4 Replies View RelatedADO Inserts Running Slow
Oct 13, 1999Hi list,
I'm a long time lurker on this list and really enjoy the discussions, although I rarely get a chance to participate.
Here is my situation: We are importing chunks of data (500 records at a time) from a C++ interface. The records have to be transformed before inserting into the target table which I am doing using a stored proc which is working fine. The records are in memory in C++ and the programmer is looping through the records building inserts into a temp table through ADO (which my proc picks up). The server business object is using the connection.execute method which is inserting one record at a time. That part of the process is taking over 15 seconds for 500 records which is the bulk of the total time.
My question is: Using ADO is there a better way to insert these records into the temp table? I see mention of a recordset interface but my programmers are new to ADO and since I am the DBA and have never used ADO, I am not sure what to tell them.
Any insight would be greatly appreciated.

Slow Running Cursor...
Apr 14, 2004I have linked three SQL Servers together, and have written a stored proc that has a cursor that joined three tables from one of the linked servers. When I pull the SQL out of the cursor definition and run it in a query window it runs fine, but when I run the stored proc that simply steps through the same select result set it is too slow for words. It also throws a warning about serial isolation levels. Is there any way I can fix this.

Need Help, DTS Is Running Extremely Slow!!!
May 13, 2004Hi guys.
I have a DTS package ON SQL 2000 which transfer data from AS400 to SQL 2000 using an ODBC Client Access 5.1 (The DSN was configured by a sysdmin on the AS400 so it is configured properly).
When i execute the package manualy (by right click and "execute package") the package runns fine and ruterns data in no time (Eproximatly 30000 rows in 15 sec).
The problem starts when a job executes the same packagee!!!
When i start the job, the DTS package is running Very Very Slow!!!!
sometime it takes Hours to return a few rows! and it seems that it is stuck.
The SQLAgent is running as a NT Account with Administrator rights, and has full access to the AS400!! so the problem is not the Agent.
by monitoring the AS400, i have noticed that the job/DTS is retreaving the first fetch quickly , and then it is in a waiting status
i have tried everything and cant seem to get this problem fixed
Does anyone know what could be the problem?
I Need Help Quick!!!
Thank You

Slow Running Proc's
Jan 30, 2008Hello All,
I have two procedures being run one after the other.
when I run proc1 it runs for about 15 min.
Now the proc2 is dependent on proc1, when I run proc2 it runs for 45 min.
If I run both the proc's simultaneously through .net code it takes more than 1 hour. Can anyone of you tell me where would be the problem.
Thanks in Advance.

Urgent SQL Jobs Running Very Very Slow
Dec 29, 2001Hi,
I have SQLServer 6.5 SP5a update running on Windows NT 4.0 SP6
with 4 gig RAM and 4 processor.
Suddenly the SQL 6.5 jobs running on the production server started running very very slow. A job that suppose to run in 30 minutes are running like 2 hours and completing successfully.
(I suspect the after the Norton Anti virus automatic live update may be the reason but not the Second Vulnerability as mentioned by Microsoft Bulletin last week)
I check the SQLServer, ran the performance monitor, checked pagefiles, disk space, databases,memory, tempdb. Everything seems to be normal.
I rebooted the server, checked any other process making that slow. But no use.
Please help me out with this issue as this is a production and the CRM applications from the clients uses the database server.
Thanks in advance,
Anu
Crystal Reports Running Slow ??
Nov 9, 2004All,
I have been tapped to help with fixing a reporting tool. We have a Sql Server database/crystal reports(10) setup. I havent had the chance to look at the tables in the DB yet, but I was told that aggregate tables were used. In my past experience with crystal reports, we used database views to feed crystal reports (in Oracle). I was thinking that I could somehow use views instead of tables and then try to re-index the base tables and compile satitics (if theres such a thing with Sql Server). I was also going to look into bottlenecking and locking (table locking as opposed to row or page locking for the lookup tables...to reduce overhead on the main tables) but, I'm not sure if it'll make a difference since this is just a demo server with no major traffic hitting it yet.
The question is, does anyone have any experience with crystal reports running slow with Sql Server, what should I look out for??

Update Query Running Very Slow
Apr 17, 2008Hi all,
I'm having what you might call an optimisation issue - but I'm also not sure if my approach to this problem is right. I've spent the whole day trying various methods but none seem to be performing as admirably as I'd hoped.
Basically, here's the scenario:
1. Log files are being inserted into a SQL table via Log Parser 2.2.
2. I have a lookup table of ip address ranges to countries and other geographic data.
3. Once the log row has been inserted from Log Parser, I want to update the same log table with data from the lookup table.
The main problem seems to be the updating (the initial insert from Log Parser is lightning quick).
I initially wrote a trigger on AFTER INSERT on the log table that converted the actual user's IP address into IPNumber format using a simple algorithm, then pumped the IPNumber into a quick select query which retrieved the geolocation data. Then, in the same trigger, there was an update statement which basically said:
update dbo.Logs
set [Country] = @Country
where [IpNumber] = @IpNumber and [Country] = Null
Therein lies the problem. The update statement slows everything down to almost a standstill and also seems to obtain a lock on the table.
Critical factors:
1. The log table must remain readable.
2. The query must execute in seconds -- not over half hour :)
I've experimented with various combinations of indexing, so far to no avail.
Any suggestions would be very much appreciated.
Regards

View 22 Replies View RelatedSlow Running Insert Statement
Apr 6, 2007I support a website (ASP.NET 2.0) where recently users have been unable to insert data due to timeout issues. The functionality executes a query that inserts a single row into a SQL Server 2005 db table. I tried running this query from the backend, and it took 4:48 to insert a single row! Interestingly, after that initial agony any similar inserts I tried took no time whatsoever. I have checked the execution plan, but unfortunately don't really know what I'm looking for with inserts, as most of my experience with execution plans is with select statements. Any resources anyone could point me to for troubleshooting this would be much appreciated.

Slow Running SELECT TOP Query
Aug 27, 2007I have a SELECT TOP query in order to return x number of top records from a table which has the indexing service enabled on it, such as this :
SELECT TOP(15) * FROM [TableName] ORDER BY [ColumnName]
and also there are not that many records(MAX 100 rows) kept in the table at the moment however, it will grow later.
The issue stems out from the ORDER BY [ColumnName] part of the syntax that changes the TOP selection order which makes the query to run very slow as I have also analyzed in the SQL SERVER QUERY ANALYZER.
Anyhow, I need to have the ORDER BY statement to show the data based on different columns either ascending or descending.
There might we workarounds to achieve the same goal that I am not aware of.
Any thoughts is appreciated.
ASYNC_NETWORK_IO Qyery Running Slow
Oct 5, 2006I am running a Stored procedure which select from a table and returns approx 800000 records. When calling from any client machine it takes long time to return the result (90 sec). It waits for ASYNC_NETWORK_IO which is pushing the result to client. If select statement is used with TOP operator to return less number of records it executes faster. When calling from the server the stored proc returns data in 13 sec with all records. In another machine of identical HW and configuration this problem is not there. Can anyone help how to improve ASYNC_NETWORK_IO issue?

Application Slow - Running Double Take 4.4 On SQL 2000
Jun 6, 2005Hi,
We are having SQL2000 Advance Server.
4 processor with hypherthreading, Memory 4 GB and it is a high transactional OLTP server. We are also running Transaction Replication on that server.
We recently bought Double Take and implemented on the server with File Difference with block check sum option for Disaster Recovery Purpose.
The Queue and the Log file folder is on local drive where the system doesn't use that folder except double take.
We are replicating from Source to Taget thru the WAN (DS3).We are replicating approx. 200 Gig of Data but just the difference.
Now the CPU usage is normal,Memory utilization is normal, but the network is a major problem as the Applications connecting to the Server timesout and the applications running very slow.
We have set just like the Tech support recommended.
I would appreciate, if someone give us some recommendations to run the double take without any problem.
Thanks in advance.

Slow UPDATE - Running For 16 Hours And Counting...
Jun 7, 2004The following basic UPDATE SQL statement has been running for 16 hours and counting. I need to get this done ASAP.
UPDATE Recipients SET UndeliverableTime = getdate()
FROM Recipients
INNER JOIN Domains ON (Recipients.DomainID = Domains.ID)
INNER JOIN Undeliverables ON (
Recipients.UserName + '@' + Domains.Domain =
Undeliverables.EmailAddress)
Is there any way I can see how far this has gone and how long it will take to finish? Will this take another hour to finish or another week?
Both tables (Recipients and Undeliverables) have approximately 80 million records
I did a nearly identical operation with another table that had only 7 million records and it took 10.5 hours. I hope this doesn't scale linearly to 115 hours.
I am tempted to cancel, retune, and rerun but that may be trigger a really expensive rollback operation that could take days. Any ideas?
thanks!
Database Running Slow After Moving To Another Serv
Apr 30, 2007Hi,
My database was previously running on sql2000 with 2 gigs of RAM and 2 x 2.8ghz XEON processors, and was running pretty decently.
I've now upgraded to SQL2005, 8 gigs of RAM, and 1 Intel 5130 2ghz processor (supposed to be more CPU power than previously)
The problem is its now running very SLOW.
I have run a trace and I'm finding queries that used to take 50,000 reads are now taking 1.4 million reads (25x more) The system runs for a decent amount of time but then SLOWS down massively for awhile. I can't find any cause yet.
What could be causing this ? What steps can I take towards resolving this? I have ran Tara's isp_ALTER_INDEX to try and help, I'm not sure what else to do.
Any suggestions are GREATLY appreciated..
Thanks very much,

this actually increase execution time by 20 seconds.Below is the stored procedure I am currently using that loops internally 24times and returns the data.Can anyone suggest a better way / any improvements I could make ?Many ThanksSteve-----------------------------------------------------------------------------------------------------CREATE procedure ams_RPT_Gen_Stats@strResult varchar(8) = 'Failure' output,@strErrorDesc varchar(512) = 'SP Not Executed' output,@strTest varchar(1),@strCurrency varchar(3),@strVFEID varchar(16)asdeclare @strStep varchar(32)set @strStep = 'Start of Stored Proc'/* start insert sp code here */create table ##Averages (TheHour varchar(2),Day7Avge float ,Day14Avge float ,Day31Avge float ,Day365Avge float)declare @numHour varchar(2)declare @strSQL varchar(2000)declare @Wholesalers varchar(64)declare MyHours cursor FORWARD_ONLY READ_ONLY forselect convert(char(2), timestamp,14) as TheHourfrom xactionsgroup by convert(char(2), timestamp,14)order by convert(char(2), timestamp,14)if @strTest = 'Y'select @Wholesalers = VALUE FROM BUSINESSRULES WHERE NAME ='TEST_Wholesalers'open MyHoursfetch next from MyHours into @numHourwhile @@fetch_status = 0beginset @strSQL = 'insert into ##Averages (TheHour, Day7Avge) ( select ''' +@numHour + ''', ' +'count(*) / 7.00 ' +'FROM ' +'XACTIONS INNER JOIN ' +'RETAILER ON XACTIONS.RETAILERID = RETAILER.RETAILERID ' +'WHERE ' +'(DATEDIFF(DAY , xactions.timestamp , GETDATE() ) < 8) and ' +'xactions.xactiontotal <> 0 and ' +' convert(char(2) , timestamp, 14) = ''' + @numHour + ''' 'if @strTest = 'Y'set @strSQL = @strSQL + ' and retailer.BillOrgID not in (' +@Wholesalers + ') 'if @strCurrency <> '*'set @strSQL = @strSQL + ' and xactions.XACTIONCURRENCY = ''' +@strCurrency + ''' 'if @strVFEID <> '*'set @strSQL = @strSQL + ' and xactions.VFEID = ''' + @strVFEID + ''''set @strSQL = @strSQL + ')'exec ( @strSQL )set @strSQL = 'update ##Averages set Day14Avge = ( select ' +'count(*) / 14.00 ' +'FROM ' +'XACTIONS INNER JOIN ' +'RETAILER ON XACTIONS.RETAILERID = RETAILER.RETAILERID ' +'WHERE ' +'(DATEDIFF(DAY , xactions.timestamp , GETDATE() ) < 15) and ' +'xactions.xactiontotal <> 0 and ' +' convert(char(2) , timestamp, 14) = ''' + @numHour + ''' 'if @strTest = 'Y'set @strSQL = @strSQL + ' and retailer.BillOrgID not in (' +@Wholesalers + ') 'if @strCurrency <> '*'set @strSQL = @strSQL + ' and xactions.XACTIONCURRENCY = ''' +@strCurrency + ''' 'if @strVFEID <> '*'set @strSQL = @strSQL + ' and xactions.VFEID = ''' + @strVFEID + ''' 'set @strSQL = @strSQL + ') where TheHour = ''' + @numHour + ''' 'exec ( @strSQL )set @strSQL = 'update ##Averages set Day31Avge = ( select ' +'count(*) / 31.00 ' +'FROM ' +'XACTIONS INNER JOIN ' +'RETAILER ON XACTIONS.RETAILERID = RETAILER.RETAILERID ' +'WHERE ' +'(DATEDIFF(DAY , xactions.timestamp , GETDATE() ) < 32) and ' +'xactions.xactiontotal <> 0 and ' +' convert(char(2) , timestamp, 14) = ''' + @numHour + ''' 'if @strTest = 'Y'set @strSQL = @strSQL + ' and retailer.BillOrgID not in (' +@Wholesalers + ') 'if @strCurrency <> '*'set @strSQL = @strSQL + ' and xactions.XACTIONCURRENCY = ''' +@strCurrency + ''' 'if @strVFEID <> '*'set @strSQL = @strSQL + ' and xactions.VFEID = ''' + @strVFEID + ''' 'set @strSQL = @strSQL + ' ) where TheHour = ''' + @numHour + ''' 'exec ( @strSQL )set @strSQL = 'update ##Averages set Day365Avge = ( select ' +'count(*) / 365.00 ' +'FROM ' +'XACTIONS INNER JOIN ' +'RETAILER ON XACTIONS.RETAILERID = RETAILER.RETAILERID ' +'WHERE ' +'(DATEDIFF(DAY , xactions.timestamp , GETDATE() ) < 366) and ' +'xactions.xactiontotal <> 0 and ' +' convert(char(2) , timestamp, 14) = ''' + @numHour + ''' 'if @strTest = 'Y'set @strSQL = @strSQL + ' and retailer.BillOrgID not in (' +@Wholesalers + ') 'if @strCurrency <> '*'set @strSQL = @strSQL + ' and xactions.XACTIONCURRENCY = ''' +@strCurrency + ''' 'if @strVFEID <> '*'set @strSQL = @strSQL + ' and xactions.VFEID = ''' + @strVFEID + ''' 'set @strSQL = @strSQL + ' ) where TheHour = ''' + @numHour + ''' 'exec ( @strSQL )fetch next from MyHours into @numHourend -- while fetchclose MyHoursdeallocate MyHoursselect * from ##Averages order by TheHourdrop table ##Averages/* end insert sp code here */if (@@error <> 0)beginset @strResult = 'Failure'set @strErrorDesc = 'Fail @ Step :' + @strStep + ' Error : ' +CONVERT(VARCHAR,@@Error)return -1969endelsebeginset @strResult = 'Success'set @strErrorDesc = ''endreturn 0GO
View 1 Replies View RelatedTriggers Running Slow (Update Trigger)
Jul 20, 2005am using FOR UPDATE triggers to audit a table that has 67 fields. Myproblem is that this slows down the system significantly. I havenarrowed down the problem to the size (Lines of code) that need to becompiled after the trigger has been fired. There is about 67 IFUpdate(fieldName) inside the trigger and a not very complex selectstatement inside the if followed by an insert to the audit table. WhenI leave only a few IF-s in the trigger and comment the rest of thecode performance increased dramatically. It seems like it is checkingevery single UPdate() statement. Assuming that this was slowing downdue to doing a select for every update i tried to do to seperateselects in the beginning from Deleted and Inserted and assigningcolumns name to specific variables and instead of doingif Update(fieldName) i didif @DelFieldName <> @InsFieldNamebeginINSERT INTO AUDITSELECT WHAT I NEEDENDThis did not improve performance. If you have any ideas on how to getaround this issue please let me know.Below is an example of what my triggers look like.------------------------------------Trigger 1 -- this was my original designCREATE trigger1 on TableFOR UPDATEASif update(field1)begininsert into AuditSELECT What I needENDif update(field2)begininsert into AuditSELECT What I needEND...... Repeated about 65 more timesif update(field67)insert into AuditSELECT What I needEND---------------------------------------------------------------------------Trigger 2 -- this is what i tried but did not improve performanceCREATE trigger2 on TableFOR UPDATEASDeclare @DelField1 varcharDeclare @DelField2 varchar....Declare @DelField67 varcharSelect@DelField1 = Field1,@DelField2 = Field2,....@DelField67 = Field67From DeletedDeclare @InsField1 varcharDeclare @InsField2 varchar....Declare @InsField67 varcharSelect@insField1 = Field1,@insField2 = Field2,....@InsField67 = Field67From Inserted-- I do not do if Update() but instead compare variablesif @DelField1 <> InsField1beginInsert into AUDITSELECT what I needendif @DelField2 <> InsField2beginInsert into AUDITSELECT what I needend............if @DelField67 <> InsField67beginInsert into AUDITSELECT what I needend----------------------------------------------IF you have any idea how to optimize this please let me know. Anyinput is greatly appreciated. I do not have a problem with triggersdoing what they are supposed to, they are very slow this is myconcern. The reason I gave you two examples is because i suspect ithas something to do with the enormouse amount of code inside thetrigger. both examples perform about the same whether i use the twohuge selects from the Inserted and Deleted or not.Thanks,Gent
View 1 Replies View RelatedSql 2005 Express Stalling / Running Very Slow
Mar 8, 2007Sql 2005 Express with XPP SP2 and the latest MS updates sometimes runs very slow.
A SELECT which should take a fraction of a second can take several 10s of seconds.
I have checked autoclose is OFF for database using
use master
go
exec sp_dboption 'your_db_name','autoclose'
And it is definitely showing as OFF
I've looked at the Activity Monitor and when stalled it shows one or two processes for my database which are sleeping with 1 or 2 open transactions. When I look at their details they are simple select statements.
Often when my computer should be idle SqlServer.exe can be consuming 20 - 30% of cpu
I've noticed that I have TWO sqlservr.exe showing in my Task Manager, Processes display
One sqlservr.exe is 27K using about 17% even tho computer is idle has username NETWORK SERVICE
Other sqlservr.exe is 343K using 0% has user name SYSTEM
I don't know why.

Data Flow Task Running Very Slow
Jun 11, 2007Hello,
I developed an SSIS package doing a nightly load into a data warehouse. We have an 8 hour loading window - currently the package takes 16 hours to complete.
I isolated the problem to a Data Flow task where +-35% of the time is spent. This task is pretty straight forward:
- OLE DB source, reading +- 800,000 rows from a SQL server database
- 13 Lookups in sequence, to get surrogate keys from dimension tables. Lookups are all on GUIDS.
- An aggregation
- OLEDB target, fact table in a SQL server database.
It seems unreasonable for the this task to take over 5 hours. It spends the majority of time on the lookups - not so much at target, source and aggregation.
Any comments and advice will be greatly appreciated.
Thanks.
