The database is about 5 Gb and the transaction log is about 13 M
and it takes 11 hours to do a full back up.
I am not sure why it takes that long? Is there any thing I can check?
IT is SQL v7.
Thank you
Hi all,
I have a stored procedure that is called from a VB.NET application that takes an enormously long time to execute. In the QA it only takes 10sec but in the application it takes ages. The stored procedure is as follows:
PROCEDURE NAME IS SPTOPTWENTYUSERS
SELECT TOP 20 STRUSERNAME,SUM(INTBYTESRECVD) AS INTDOWNLOAD FROM TBLISAWEBLOGS
WHERE DTELOGDATE BETWEEN @BEGINDATE AND @ENDDATE
GROUP BY STRUSERNAME
ORDER BY INTDOWNLOAD DESC
The code that runs it is as follows:
sSQLString = SPTOPTWENTYUSERS
Using cnn As New SqlConnection(GetPath)
Try
Dim cmd As New SqlCommand(sSQLString, cnn)
Dim dr As SqlDataReader
With cmd
.CommandType = CommandType.StoredProcedure
.CommandTimeout = 0
.Parameters.Add("@BEGINDATE", SqlDbType.DateTime)
.Parameters.Add("@ENDDATE", SqlDbType.DateTime)
.Parameters("@BEGINDATE").Value = dtpStartDate.Value
.Parameters("@ENDDATE").Value = dtpEndDate.Value
End With
cnn.Open()
dr = cmd.ExecuteReader
Any help on why this happens would be much appreciated.
thanks
Hi,
How much time will it take to restore a DB 300MB long in SQL Server 2005 Express?
Full Restore with recovery option?
The thing is that I made a restore process and its been running for about an hour now.
When I open the Management Studio on the database folder it shows "Restoring..."
Is this normal?
Tnx
Recently my system encounter some problem when retrieving certain record from MSSQL.
For an example i have a database which contains 1.5 million of members. so i have a perl scripts that will execute to query based on certain range.
the schedule like below:
1 script - 1-250k (Query finish less than 5 mins)
<interval 5 mins>
1 script - 250k-500k (Query finish less than 5 mins)
<interval 5 mins>
1 script - 500k-750k (Query finish less than 5 mins)
<interval 5 mins>
1 script - 750k-1M (Query finish in 1++ hours)
<interval 5 mins>
1 script - 1M-1.25M (Query finish in 1++ hours)
<interval 5 mins>
1 script - 1.25M-1.50M (Query finish in 1++ hours)
END
After the 4th query, the query seems to work very slow, and this problem only raise on windows 2003 with mssql 2005, current server that run smoothly is win2k with mssql2000.
anyone have any idea on this problem either cause by operating system and database or related to something else?

View 6 Replies View RelatedHi,
It seems inserting records takes a relatively long time. My guess is it needs time to allocate disk space for the extra space needed. Assuming this is true, are there any DB settings that allow auto space allocation in bigger chunk? I am looking for something like "DB growth factor" or " Table growth factor"
Thanks for any info.
Dear friends,
Our package which at the time of normal execution takes 2-2:30 mins for fetching data on VPN with some select queries. But some times its job runs for hours and hours. What could be the exact reason behind it? I guess its queries are stuch somewhere, but not when we run from the BIDS or run the job manually.
Please help. Thanks.
Hello,

The table has about 25 cols and 5 constraints (1PK, 4 FK). No triggers no cascade.
What can be the reason and what can i do to accelerate?
Thanks

I have a database with 2 almost identical tables.
Each one is about 1.2 Billion rows, 0.5 Tb each.
I've truncated one of them and started SHRINK DB WITH REORGANIZE PAGES
It is running already for 3 days.
When should I start to worry :)
Thank you in advance

Hi,
Its a common issue with reporting services, exporting a report with huge data to excel takes long time to render. Im facing the same issue. Trying to export a SSRS 2005 report to Excel 2003 takes very long time.
Problem 1:
The time taken to generate the excel report is pretty long (about 10 minutes) as the report runs to hundreds of pages. (The excel has about 30,000 rows and is ~15 MB)
Problem 2:
Once I open the excel and close it the size reduces to half of it. This is understood because of lot of characters values in the report that can be represented as single byte string, that€™s probably where Excel is making a difference. In Reporting Services it always write strings as 2-byte Unicode, but Excel will always try to compress to single byte when possible.
Am majorly concerned about the Problem 1. Any solutions would be highly appreciated. Thanks in advance.
I have a report which is fairly simple but takes a very long time..
It involves the incidents being counted by categories hence it has several Union All.
Also the report numbers are generetd through 2 tables hence within every Union All tehre is a left or an Inner join.
sample code:
SELECT
1 Sort_Order,
COUNT(*) AS Call_Count,
'Incident Resolved at Level 1' AS Count_Type
FROM HOUAPPS237.CallsAndIncidents.dbo.PROBSUMMARYM1 T1
INNER JOIN HOUAPPS237.CallsAndIncidents.dbo.PROBSUMMARYM2 T2
ON T1.NUMBERPRGN = T2.NUMBERPRGN
WHERE PROBLEM_STATUS = 'closed'
AND T2.THIRD_ASSIGNEE IS NULL
AND T2.THIRD_ASSIGNMENT IS NULL
AND T1.SECONDARY_ASSIGNEE IS NULL
AND HAL_FIRST_RES='t'
AND DATEPART(mm, DATEADD(hour, -@offset, CAST(T1.OPEN_TIME AS DATETIME))) = @MONTH
AND DATEPART(yy, DATEADD(hour, -@offset, CAST(T1.OPEN_TIME AS DATETIME))) = @YEAR
AND T1.OTI_ORIGINATOR IN (SELECT Userid FROM HOUAPPS286.HALServiceDesk.dbo.ServiceCenterAgents)
UNION ALL
-- Calls RESOLVED BY L2
SELECT
2 Sort_Order,
COUNT(*) AS Call_Count,
'Incidents Resolved at Level 2 or 3' AS Count_Type
FROM HOUAPPS237.CallsAndIncidents.dbo.PROBSUMMARYM1 T1
LEFT JOIN HOUAPPS237.CallsAndIncidents.dbo.PROBSUMMARYM2 T2
ON T1.NUMBERPRGN = T2.NUMBERPRGN
WHERE (HAL_FIRST_RES<>'t' OR HAL_FIRST_RES IS NULL)
AND PROBLEM_STATUS = 'closed'
AND DATEPART(mm, DATEADD(hour, -@offset, CAST(T1.OPEN_TIME AS DATETIME))) = @MONTH
AND DATEPART(yy, DATEADD(hour, -@offset, CAST(T1.OPEN_TIME AS DATETIME))) = @YEAR
AND T1.OTI_ORIGINATOR IN (SELECT Userid FROM HOUAPPS286.HALServiceDesk.dbo.ServiceCenterAgents)
UNION ALL
could you suggest what might be the reason why teh report churns for so long.
thanks,

I have a vb.net application using report services that has a big delay when I set the parameters with which to call the report.
I create a new reporting.reportviewer.
I set the ReportServerCredentials.NetworkCredentials, ReportServerUrl, ProcessingModem, ReportPath and everything is fine.
When I call SetParameters with a very simple parameter set, I get a delay of between 0.5 and 2.5 seconds. That delay is very noticible to the users. Below is an extract of a sql profiler trace to a database showing the start time, end time, event class and data text of the sql. I've marked the area with the delay in red.
I have no idea what is happening at that time, but Is there anything I can do to get rid of that delay?
It seems that it could be the first time the my application has had to interface with reporting services.

Hi,
I need to modify existing table in my database to varchar(max) from varchar(2000)
This table contains 30 million plus rows and has more than 70 columns.
now when i am running alter command for this it take too long(more than 9 mins) which is not acceptable. . Is their any way to reduce this execution time
Following is the query i am using for this
ALTER TABLE Receipt
ALTER COLUMN CUSTOM VARCHAR(MAX) NULL
Please let me know if you have any suggestion to improve this

We are using SQL Server 2005 mirroring with the witness server.
In most cases whenever a failover was triggered we saw it happen in a matter
of a few seconds. However, the last time it took about 15 minutes - we suspect
due to Connection being blocked.
Would appreciate any information on what could cause this?
We have 2 databases that run on the server.
I have a table tblCustTrans which contains
custid int
transid int
startdate datetime
value int
the custid, transid and startid are composite primary key.
the table contains more than 10 million records. Now i want to fetch record for
select * from tblcusttrans where startdate > = 10/10/2006 10:00:000 and startdate <= 10/10/2006 11:00:000
This statement is taking more than 2 hours to fetch the data. is there a way to fetch the record with less time
Regards
Hi All,
I'm trying to rebuild my master database for sql server 2000. The process of rebuilding stared fine. But it is almost 4 hours since it got started. Performing it on a test system. Got doubtful and started the same on another test system. Issue is same and it is almost 2 hours. The Db size is less than 100 MB in both cases. IS IT NORMAL? I've tried the same for SQL SERVER 2005 and it got finished in couple of minutes. Please advise.
Hi,
we've created a ata Flow task to execute several aggregations. Our Task access database using OLE DB source and selects data out of our staging tables (we've analyzed the query using MS SQL Management Studio which didn't showed any issues). But when we try to run our dataflow task using SSIS (debug mode and DTEXEC from command line) we experince that tasks seem to stop during processing.
Unfortunately we didn't found a way to see long logfile entries which explain the issue to us.
We do use several aggregation tasks divided in 4 sequences. Unfortunately we just see one logical processor out of 4 logical processors working. It is a Windows 2003 SP2 machine with SQL 2005 SP2 on top of it.
Is there any solution to use all processors to one package for parallel execution?
So basically we experience two issues:
- SSIS seems to stop somewhere in thre middle
- SSIS just uses one processor instaed of all four
your advice is appreciated
I broke up my cube into 24 partitions. There are about 630M total fact rows in that cube.
When I open the cube to browse in BIDS or SQL Management Studio it takes very long time to open (I think 30 minutes).
Profiler does not show that it's running a query, but messages like this keep appearing throughout the time it's opening to browse:
Progress Report Begin, 14- Query, Started reading data from the 'p0' partition.
Progress Report End, 14- Query, Finished reading data from the 'p0' partition.
Progress Report Begin, 14- Query, Started reading data from the 'p10' partition.
Progress Report End, 14- Query, Finished reading data from the 'p10' partition.
and goes on like that....
Hi,
The scenario is the data comes from various sources and its staged into staging database. From this staging database it goes into data warehouse database. Everyday this staging database is truncated and repopulated from various sources.
I've a dimension table called DimCustomers which consists of around 300,000 rows and has lots of different types of SCD columns. It takes around 4-5 hours to load data from staging to this dimension table. Currently I'm using a For Loop container which uses a store proc to extract 15000 rows each time and populate my dimension tables. First couple of loops it goes off quickly but as and when the number reaches half of the count it slows down and hence it takes around 4-5 hours to load data.
What would be the best approach to populate this kind of dimension table.
Thanks
I have a table having 220 lakhs of records and one of the column is Full Text enabled.We have used ContainsTable() to search for data, but we are unable to get results as expected. so we done rebuild.During Index Rebuild, population is failed.I have found this error in error log and it is saying to do resume population.So I want to know how long it takes to complete Resume population process.
look at the below more details about FT Index table.
Row count - 22155112
Index space - 1,903.250 MB (1.9 GB)
Data space - 87,552.258 MB (87 GB)
sqlserver2008 R2
and the below query we have used
HTML Code:
SELECT Distinct top 50 cal.case_id,cal.cas_details
From g_case_action_log cal (READUNCOMMITTED)
inner join containstable(es.g_case_action_log, cas_details,
' ("235355" OR "<br>235355" OR "235355<br> ") ') as key_tbl on cal.log_id = key_tbl.[key]
Where cal.product_id = 38810 ORDER By cal.case_id DESC
This query is not going to search in recent inserted/updated rows. this is the actual issue we are facing.
how to fix this error and if population need to be resume, then how long takes to do resume population.
I have SQL 2014. When I try to restore a user database using SSMS GUI, the Restore Database Pop up box never pops up. This happens for any database on this server at any time. Sometimes I get the pop up, some times I dont get.
So I tried to click on Databases on Top and Restore Database, and then select the db that I need to restore from Drop down, then it shows "creating restore plan selecting backups" but it takes forever.
We have full backup and trn log backups every 30 mins. So is it trying to get all these backup files in the background causing this issue? If yes then how to overcome this?
We have a proc that adds some fields to a few tables of ours and normally there are no issues. For one of our client databases this process is taking anywhere from 5-10 minutes to add the fields. This causes an issue where the app will timeout waiting. After plugging around and looking at the proc and trying different items i found it to only be for this one database and ONLY when there is data in the table. If i truncate the table and run the same procedure everything is fine. Tables all have same index on 4 columns and the columns being added are not indexed because of the stupid hoops we have to jump thru to pre-pivot data for our reporting package.

Hi,
I have problem with JDBC 2005 (1.1) running against SQL 2005 Express edition (SP2). Sometimes, the statement takes long time (more than 10 seconds). Sometimes, the same statement takes just a few seconds. It is very unpredictable.
The query that we have problem is most of the time is join sql statement.
Does anyone see this problem?
Thanks,
Hi,
I was just wondering if anybody came across this behaviour where closing a Fast Forward Read only cursor takes abnormally long time to close. I am running SQL Server 2005 standard edition.

SQL Server 2008 r2 - 6 GB memory...I attempted a backup on a 500GB database but it was taking way too long. I checked the resources on the box and saw the CPU at 100%. I checked the SQL Server activity log and saw a hung query (user was not even logged on) that had multiple threads so I killed it and now the CPU utilization is back to normal.
Trouble is, now all of the threads in the activity monitor for the backup show 'suspended' and the backup appears to be not doing anything.
How is it possible that a 133MB SQL7 database, the backup of the database itself takes 2 seconds, the transaction log backup takes 25 minutes??? We are doing log backup every 10 minutes, and appending.
Thanks.

I am using VS2005 (VB) to develop a PPC WM5.0 Program. And I am using SQLCE 3.0. My PPC Hardware is in 400MHz.
The question is when the program try to insert the first record into sdf database after each time the program started. It takes a long time. Does anyone know why and how can I fix it?
I will load the whole database into a dataset when the program start and do all the "Insert", "Update", "Delete" in this dataset and fill it into database after each action.
cn.Open()
sda = New SqlCeDataAdapter(SQL, cn) 'SQL = Select * From Table
scb = New SqlCeCommandBuilder(sda)
sda.Update(dataset)
cn.Close()
I check the sda.update(), it takes about 0.08s for filling one record into database normally. But:
1. Start the PPC Program
2. Load DB into dataset
3. Create a ONE new record in dataset
4. Fill back to DB
When I take this four steps everytime, the filling time is almost 1s or even more!
Actually, 0.08s is just a normal case. Sometimes, it still takes over 1s to filling back a dataset which only inserted one record when the program is running. (Even all inserted records are exactly the same in data jsut different in the integer key)
However, when I give up the dataset and using the following code:
cn.Open()
Dim cmd As New SqlCeCommand(SQL, cn) ' I have build the insert SQL before (Insert Into Table values(XXXXXXXXXXXXXXX All field)
cmd.CommandType = CommandType.Text
cmd.ExecuteNonQuery()
cn.Close()
StartTime = Environment.TickCount
I found that it is still the same that the first inserted record takes more time, but just about 0.2s. And the normal insert time is around 0.02s. It is 4 times faster!!!
ok, here is an interesting one.
We have multiple jobs that run the following SQL Backups to Permanent Backup devices.
Backup Database DBX to DBXFull with NoInit - 1 am
Backup Database DBX to DBXDiff with Differential, NoInit - 12 pm
Backup Log DBX to DBXLog with NoInit - every hour on the hour
the devices are in path E:SQLBackups<databasename>
E: is on a SAN
Every Night E: is backed up by legato, When Legato Starts to backup the directory, at the hour a transaction log backup occurs. The Backup Fails and The Database Is Taken OFFLINE.
Questions are as follows.
What is causing the db to be taken offlline?
How can i stop the db from being taken offline while still mainting my current backup strategy.
Temporarily we have stopped tlog backups during the directory backup phase (legato) and then resume them when it is complete.
Difficulty Level: we will not be using Legato's SQL Plugin for the backups, they have to be performed with jobs and SQL Backup.
sql 2005 stnd on a server of decent spec.
dbase in question is only about 5GB on a 450GB partition.
at the begining of the month I run:
BACKUP LOG [objectstore] TO DISK ='D:BackupsProdackup_objectstore.BAK'
WITH NOFORMAT , INIT , NAME = N'objectstore backup'
and then every 10 minutes (within working hours) for the rest of the month I
run:
BACKUP LOG [objectstore] TO DISK ='D:BackupsProdackup_objectstore.BAK'
WITH NOFORMAT , NOINIT , NAME = N'objectstore backup'.
The amount of data that gets backed up is the same through out the month and
the loading on the server as a whole also stays constant throughout the month
- NOTHING increases throughout the month that would affect this server in any
way, yet at the begining of the month the backup takes 10 seconds, and at the
end, it gets up to 5-6 minutes.
why?
