Trying to come up with a way to monitor (without profiler, hopefully with a job and a select statement) a specific sql job that may cause a problem if the duration is too long. It seems that there is an sp called sp_sqlagent_log_jobhistory that shoves a record in sysjobhistory, but only after all the job steps run. Anyone tried this before?

If I start a long running query running on a background thread is there a way to abort the query so that it does not continue running on SQL server?
The query would be running on SQL Server 2005 from a Windows form application using the Background worker component. So the query would have been started from the background workers DoWork event using ado.net. If the user clicks an abort button in the UI I would want the query to die so that it does not continue to use sql server resources.
Is there a way to do this?
Thanks
Is there any way to configure repl. monitor in 2005 to view all the publications that go
via a distributor in one place? (as opposed to having to link to each publisher to see the replictaion status).
we have 7 publishers going throigh one distributor and in 2000 could see them all on the distributor...now have to connect to each publisher & look on each...
Thanks

I have a pretty complex query that aggregates lots of data and inserts multiple rows of that data into a reporting table. When I call this SPROC from SQL Server Management Studio, it executes in under 3 seconds. When I try to execute the same SPROC using .NET's SqlCommand object the query runs indefinitely until the CommandTimeout is reached. Why would this SPROC behave differently with the same inputs, but being called from .NET? Thanks for your help!
View 3 Replies View RelatedHi everyone.... I'm trying to execute this update statement... It takes an eternity... any ideas on how to rewrite or speed it up?
It's a several step process... below is everything that i run, one step at a time. The final update statement is what takes so long. It should only affect about 2600 rows out of a potential 9000. That's why I'm confused on the response time
select d.olddevicename, de.device, d.newdevicename into #temp9
from dns d, devices de
where de.device = d.olddevicename
update #temp9 set device = newdevicename where olddevicename = device
update devices set device = #temp9.device from #temp9, devices where #temp9.device in
(select #temp9.device from #temp9, devices where #temp9.olddevicename = devices.device)

Hi all,
I have 3 three scheduled job: one runs onece a day, one runs once per hour, and another runs every 17 minutes. It is a NetIQ application. I just scheduled SQL Server maintianace job last night which ran at 2:00Am and 4:00Am. This morning, I came in office and found all my jobs were still running; and they were all blocked by the first 3 jobs. I had to kill all of them. In this afternoon, I kicked off one of my many DTS packages which runs usually about 40 minutes, but it failed. I tried several times but no luck. I suspected one of user tables corrupted or one of stored procedures corrupted. After I recycle the server, and dropped the table and the stored procedure, and recreated them, the package went fine. The store procedure involves many updates and inserts.
The question I have is: is it possible to cause this problem because I killed the unfinished jobs (especially the sql maintanace job)?
NOTE: the sql maintanace job does not include the backup of database and transaction log.
When I execute the following stored procedure it runs for about a minute.
CREATE PROCEDURE EquipmentListByProduct
(
@iProdTypeId int
)
AS
SET NOCOUNT ON
DECLARE@iError int, @iRows int
SELECT pn.prodTypeId, pn.prodId, pn.prodName
FROM prodNames pn
WHERE pn.prodTypeId = @iProdTypeId
SELECT@iError = @@ERROR, @iRows = @@ROWCOUNT
IF ( @iError <> 0 )
BEGIN
RETURN@iError
END
IF ( @iRows = 0 )
BEGIN
RETURN-1
END
RETURN@iError
GO
The table only has 22 records.
Do I need to index the table? If so how do I do this?
My backups are running 5-6 hours on SQL2000. I'm sure they only used to take 1 hour or so. On another server, backing up the same database (both about 50 gig), the backup only takes 45 min - 1 hour. What can I look at to see why it's taking so long ?
(edit) I'm using a maint plan to backup to disk
1. could any one tell me in a simple way how to troubleshoot long running queries.
2.what is the default recovery model

I've got a server (SQL 2K, Win2K) where the backupshave started running long.The database is a bit largish -- 150GB or so. Up untillast month, the backups were taking on the order of4 to 5 hours -- depending on the level of activity on theserver.I'm using a T-SQL script in the SQLAgent to run thebackups. Native SQL backup to an AIT tape drive.Now, for no apparent reason, the backups are takingon the order of 24 to 26 hours. The backups completesuccessfully -- no errors, just taking an outrageouslylong time to complete. DBCCs check out AOK, noproblems with the database.No changes to the machine. No hardware changes. Nosoftware changes. Weird.Multiple tape media have been tried -- it's not a caseof a tape going bad.We've had no problems with this box for almost 4years. Now it's gettin' jiggy with us!Any ideas on where to start with this one?Thanks in advance.
View 1 Replies View RelatedHi. I'm fairly new to SSRS, and very new to this forum. I have a report based on a stored procedure. I've optimized the procedure so that it runs from 2-4 minutes (previously over half an hour). However, when I run the report that calls the sp, it runs forever (well over 45 minutes in some cases), and the users basically give up on it. Any ideas of why this happens and what steps I can take to improve performance?

I need to execute a long running package (it takes about 16 hours to finish) to load a data warehouse for the first time with all historical data. This package it's a master package and execute other packages; I log the start time and the finish time of the package in a table to manage future incremental loads.
I executed the package on sql server where it is saved, but after 8 hours it was running, a new package was started automatically. Then two more packages started .. each every two hours.
I set the MaxConcorrentExecutable = 4, this could affect this strange behavoir ?
Anyone could imagine wath happened ?

Hi,
I'm trying to optimize a long running (several hours) query. This query is a cross join on two tables. Table 1 has 3 fields - ROWID, LAt and Long. Table 2 has Name, Addr1,Addr2,City,State,Zip,Lat,Long.
Both tables has LatRad - Lat in radians, LonRad- Lon in Radians. Sin and Cos values of Lat and Lon are calulated and stored to be used in the distance formula.
What I'm trying to do here is find the nearest dealer (Table 2) for each of Table 1 rows. The Select statement takes a long time to execute as there are about 19 million recs on table 1 and 1250 rows in table 2. I ran into Log issues- filling the transaction log, so I'm currently using table variables and split up the process into 100000 recs at a time. I cross join and calculate the distance (@DistValues) and then find the minimum distance (tablevar2) for each rowid and then the result is inserted into another Table (ResultTable).
My Code looks like this:
Declare @DistValues table (DataSeqno varchar(10),Lat2 numeric(20,6),Lon2 numeric(20,6),StoreNo varchar(60), Lat1 numeric(20,6),Long1 numeric(20,6),Distance numeric(20,15))
Declare @MinDistance table (DataSeqno varchar(10) primary key,distance numeric(20,15))
Insert into @DistValues
Select DataSeqno,T.Lat Lat2,T.Lon Lon2,S.StoreNo,S.Lat Lat1,S.Long Long1,
distance=3963.1*Case when cast(S.SinLat * T.SinLat + S.CosLat * T.cosLat * cos(T.Lonrad - s.Lonrad) as numeric(20,15)) not between -1.0 and 1.0 then 0.0 else acos(cast(S.SinLat * T.SinLat + S.CosLat * T.cosLat * cos(T.Lonrad - s.Lonrad) as numeric(20,15))) end
from dbo.TopNForProcess T , dbo.Table2 S where Isnull(T.Lat,0) <> 0 and Isnull(T.Lon,0)<> 0
Insert into @MinDistance
Select DataSeqno,Min(distance) From @DistValues Group by DataSeqno
Insert into ResultTable (DataSeqno,Lat2,Lon2,StoreNo,LAt1,Long1,distance)
Select D.DataSeqno, D.Lat2, D.Lon2, D.StoreNo, D.LAt1, D.Long1, M.distance from @DistValues D Inner Join @MinDistance M on D.DataSeqno = M.DataSeqno and D.Distance = M.Distance
I created a View called TopNForProcess which looks like this. This cut down the processing time compared to when I had this as the Subquery.
SELECT TOP (100000) DataSeqno, lat, Lon, LatRad, LonRad, SinLat, cosLat, SinLon, CosLon FROM Table1 WHERE (DataSeqno NOT IN (SELECT DataSeqno FROM dbo.ResultTable)) AND (ISNULL(lat, 0) <> 0) AND (ISNULL(Lon, 0) <> 0)
I have indexes on table table1 - Rowid and another one with Lat and lon. Table2 - Lat and Long.
Is there any way this can be optimized/improved? This is already in a stored procedure.
Thanks in advance.
I have a SQL procedure that can take several minutes to complete. I allow users to initiate the process through a web site and view a progress bar. When the process is running, though, the site slows to a crawl or times out completely. That long running process seems to block all other queries on the database. Is there a way to give this process a low priority or somehow throttle its resource use so that the other web processes can get a chance to run in a timely manner?
Thanks for any advice.
Hello,
I am having some difficulty with data-driven processes in an internal web application using ASP.NET framework 2.0 with SQL Server 2000.
I have a facility where the user enters search criteria to retrieve a list with the idea being that when they click a button the list set is migrated to a table as a batch. The SQL Server processes to perform the database operations can take up to 5min because of volume of data and relational complexity, which is fine.
The only problem is that I'm having trouble managing the SQL Server process if the user closes the browser or go to a new URL etc. If this happens on the client side it's like the HTTP request is terminated but the SQL statement left on the SQL Server still running, eventually it runs to completion but I would prefer the SQL process to also be abandoned and rolled back.
Any idea what is happening here and how it can be handled?
Thanks for any help.

Hello,
I have a very long running stored proc (import and transformation of 2-3 M. records). The duration of about 1h is not the problem.
My problem is that i want to send some notifications to the UI for showing a progress counter in the UI.
Is there any possibility to send send out a msg after certain steps (e.g. after positioning the cursor to next row) via an extended stored procedure which I could catch in my UI?
I would be very appreciative if somebody would send me a hint.
Thank you,

I’m trying to write a script that will detect long running agent jobs.
Having looked at this article:
http://www.databasejournal.com/features/mssql/article.php/3500276
It appears that agent job job id’s don’t necessarily get stored in the programname of the sysprocesses table. This is true if the agent executes an os command. It also appears that job steps do not get stored in the sysjobhistory until the step is complete so that cannot be used accurately.
Does anyone know of an effective way to find if there are long running jobs other than these methods?
I just wanted to post a follow up to a message I posted some months agoabout a long running transaction that was blocking all other users...The link is belowhttp://groups.google.com/group/comp...649bee2002646a2By using the new "Row versioning" functionality of SQL 2005, itcompletely solved this problem. By reading the books online, it saysthere is a performance impact, but that the better performance of SQL2005 in general might offset it. So far this seems to be the case. justposting it here in case anyone else has the problem. The SQL command Iihad to execute to get everything working properly was:ALTER DATABASE DBnameSET READ_COMMITTED_SNAPSHOT ON;

The query show below is designed to use seasonal profiles to compute 53 weeks of forecast data and then from that compute the number of weeks of supply of each item at each location. The query works but the volume of data produced (20+M rows) is substantial. If I limit the CTE to a single location, it run is 2 seconds and returns 41,000 rows. But when run for all locations and items, it runs for more than 4 hours. Would I do better converting the CTE to a sub-query and adding an index to improve the performance of the main query?

Is there any way to measure the progress of a long running query,
for instance, to find where in a query plan a query is in SQL 7.0?
I have a query I am running that is currently 2 1/2 hours into the
query. Since it's joining three large tables, one with 42 million rows
and two with 7 million rows, I'm expecting the query to take a
while. However, I have no way of estimating exactly how long
it will take. Before I ran it, I optimized it the best I could in
Query Analyzer using an estimated query plan, making sure I had
all the right indexes, etc. I've been trying to use the estimated cost
to project query time, but that hasn't been working since queries
with similar costs can take radically different amounts of time to
execute.
Now I'm sitting here waiting, wondering if the query is just taking
too long, and I should stop it and work on optimizing it some more
(since I will have to run a couple more queries like it), or let it
finish. But I have no clue how close it is to finishing. I've tried looking
at the Physical I/O given by sp_who2 and then trying to calculate the
number of pages it would have to read if it had to read everything
from disk, then estimating it's progress by that, but this seems dubious
at best, since I don't know a whole slew of factors (ie: how many
pages are being read from the cache, is my page calculation correct,
etc).
So, does anyone know of any way to figure out how soon a long
running query will finish in SQL 7.0?
Thanks.

View 1 Replies View RelatedI am having a problem executing long running queries from an ASP applicationwhich connects to SQL Server 2000. Basically, I have batches of queries thatare run using ADO in a loop written in VBScript. This works pretty welluntil the execution time of a single query starts to exceed some threshold,which I am trying to narrow down. I can typically run 2 - 10 queries in aloop, with the run time being anywhere from under a minute to an hour ormore. Now that this application is being subjected to run against some largedatabases (25 - 40G), I'm having problems getting the application tocontinue beyond the first query if it takes a while to run.I used SQL Profiler to try to diagnose what was going on. I can see thequery executes to completion, but immediately after completing I can see an"Audit Logout" message, which apparently means that the client hasdisconnected. The query durations vary from 45 or 50 minutes to up to over90 minutes. I have the ADO connection and query timeouts set to very largevalues, e.g. 1000 minutes, so I can't think its that.
