Working With A Package Is Extremely Slow
Nov 17, 2006
I have a package that reads the contents of 11 Excel files into various tables. Opening this package in the designer, or with DTExecUI is extremely slow. In both cases when I open the package is takes over 10 minutes to do anything. Visual Studio gives the "Visual Studio is Busy" message for 10 minutes and DTExecUI just hangs. DTExecUI actually hangs twice, once when opening the package and a second time when clicking "Execute" (totalling over 20 minutes). It seems like no matter how I try to run the package it will always hang for 10 minutes before running with no status message or anything. Once it runs it completes quickly with no errors.
The various tasks in the package are fairly simple, most being Source > Data Conversion > Destination.
Any suggestions?

Hi 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
Gil

Hey Guys
I have a huge speed issue on one or two of my SQL Tables. I have included the basic design below.
Structure
Id
ParentId
Name
Group
Id
ParentId
Name
Weight
Products
Id
Name
StructureProducts
StructureId
ProductId
Imported
StructureGroups
StructureId
GroupId
GroupProducts
GroupId
ProductId
AnswerDates
Id
AssessmentDate
Scores <-- This table is the slow table
AnswerDateId
StructureId
GroupId (nullable)
ProductId (nullable)
Score >= 0 && <= 100
Ok, Structures are the start of everything. Structures, have children. If a group/product is Linked to a parent or child structure then that group/product is visible along the structure tree flow path. Groups, like structure have children. And also like structures, if a group is given a product, then that product is visible through the structure tree flow path.
Example:
Earth [Structure]
- Asia [Structure]
--- China [Structure]
--- Japan [Structure]
----- Computer Stuff [Group]
------- Desktops [Group]
------- Servers [Group]
------- Laptops [Group]
--------- HP [Product]
--------- Dell [Product]
--------- Fujitsu [Product]
- Europe [Structure]
--- Germany [Structure]
----- Berlin [Structure]
--- Italy [Structure]
----- Rome [Structure]
----- Venice [Structure]
- America [Structure]
--- United States of America [Structure]
----- New York [Structure]
------- Computer Stuff [Group]
--------- Desktops [Group]
--------- Servers [Group]
--------- Laptops [Group]
----------- HP [Product]
----------- Dell [Product]
------- Home Stuff [Group]
--------- Kitchen Stuff [Group]
--------- bedroom Stuff [Group]
----- Washington [Structure]
------- Computer Stuff [Group]
--------- Desktops [Group]
--------- Servers [Group]
--------- Laptops [Group]
----------- HP [Product]
----------- Dell [Product]
----------- Acer [Product]
------- Home Stuff [Group]
--------- Kitchen Stuff [Group]
--------- bedroom Stuff [Group]
----- Chicago [Structure]
------- Computer Stuff [Group]
--------- Desktops [Group]
--------- Servers [Group]
--------- Laptops [Group]
------- Home Stuff [Group]
--------- Kitchen Stuff [Group]
--------- bedroom Stuff [Group]
- Africa [Structure]
--- South Africa [Structure]
----- Johannesburg [Structure]
------- Computer Stuff [Group]
--------- Desktops [Group]
--------- Servers [Group]
--------- Laptops [Group]
----------- Acer [Product]
------- Home Stuff [Group]
--------- Kitchen Stuff [Group]
--------- bedroom Stuff [Group]
----- Durban [Structure]
----- Capte Town [Structure]
- Australasia [Structure]
So the initial steps that happen (with regards to Scoring) are as follows.
1. Insert root score (which would be for a structure, a group, an answer date and either a product or no product
2. Score the next group up along the treeview, using the scores for the groups at the same level as the original group (0 score if no score exists).
3. Continue this till GroupTree is at root (parentid == null)
4. Using the next structure up along the treeview, repeat steps 2 & 3.
5. Continue steps 4 until Structuree is at root (parentid == null)
Example
Scoring a product for Johannesburg Acer Laptop would go as follows
1. Initial score for [Acer] product against Group [Laptop] for Johannesburg.
2. Calculate Score for all products (productid = null) against Laptop for Johannesburg
3. Calculate Score for [Acer] product against Group [Computer Stuff] for Johannesburg
4. Calculate Score for all products against Group [computer Stuff] for Johannesburg
5. Calculate score for [Acer] product against all root groups for Johannesburg
5.1. Group [Comptuer Stuff] and [Home Stuff]
6. Calculate score for all products against all root groups for Johannesburg
6.1. Group [Comptuer Stuff] and [Home Stuff]
7. Calculate score for [Acer] Product against Group Laptop for South Africa
8. Calculate Score for all products (productid = null) against Laptop for South Africa
9. Calculate Score for [Acer] product against Group [Computer Stuff] for South Africa
10. Calculate Score for all products against Group [computer Stuff] for South Africa
11. Calculate score for [Acer] product against all root groups for South Africa
11.1. Group [Comptuer Stuff] and [Home Stuff]
12. Calculate score for all products against all root groups for South Africa
12.1. Group [Comptuer Stuff] and [Home Stuff]
13. Calculate score for [Acer] Product against Group Laptop for Africa
14. Calculate Score for all products (productid = null) against Laptop for Africa
15. Calculate Score for [Acer] product against Group [Computer Stuff] for Africa
16. Calculate Score for all products against Group [computer Stuff] for Africa
17. Calculate score for [Acer] product against all root groups for Africa
17.1. Group [Comptuer Stuff] and [Home Stuff]
18. Calculate score for all products against all root groups for Africa
18.1. Group [Comptuer Stuff] and [Home Stuff]
etc. etc. etc...
This basicly coveres the concept behind the basic scoring methodology. Now the methodology splits into 2. The first Methodology 1, say it should do these calculations using the Exact same date as the original scored date. (Ie. if i do a score today, only scores on today will be used in the calculations). The other, Methodology 2, says that it should do the calculations on the latest available date. (Ie. If i do a score today, only scores from today and the latest before today will be used in the calculations).
Now to add another problem to this already complex process, is that each Group and each product within a structure can have either of the 2 scoring methodologies assigned to it. Also, products can only be scored against the structures and groups that they are assigned to. Ie, Acer exists in Laptop Group, in Johannesburg or South Africa or Africa, but doesnt exist in New York.
Ok, so now that i've explained briefly how this scoring works, let me get to the heart of the problem. Basicly its speed (can clearly see why), though the speed issue only comes
up in 1 Place. And that is where it has to look backwards for the latest available score for the required group, structure and product.
For this to happen i wrote a function
ALTER FUNCTION [dbo].[GetLatestAnswerDateId]
( @StructureId INT,
@GroupId INT,
@ProductId INT,
@AnswerDateId INT )
RETURNS INT
AS
BEGIN
DECLARE @Id INT
DECLARE @Date DATETIME
SELECT TOP 1 @Date = [Date]
FROM [dbo].[AnswerDate]
WHERE [Id] = ISNULL(@AnswerDateId, [Id])
ORDER BY [Date] DESC
SELECT TOP 1 @Id = ad.id--gs.[AnswerDateId]
FROM [dbo].[Scoring] gs
INNER JOIN [dbo].[AnswerDate] ad ON ad.Id = gs.AnswerDateId
WHERE [StructureId] = @StructureId
AND ISNULL([GroupId], -1) = ISNULL(@GroupId, -1)
AND ISNULL([ProductId], -1) = ISNULL(@ProductId, -1)
AND [Date] <= @Date
ORDER BY [Date] DESC
RETURN @Id
END
Now on small amounts of data (1000 rows or so) its quick, though that is due to the fact that the data is minimal, but on large amounts of data this function runs for along time. Specificly in the context of the following when there is 6 months of scoring data (100 000+ rows) to peruse.
SELECT [StructureId], [GroupId], [AnswerDateId], [ProductId], [Score]
FROM [Scoring]
WHERE AnswerDateId = GetLatestAnswerDateId([Structure], [GroupId], [ProductId], null)
AND [StructureId] = South Africa
AND [GroupId] = Computer Stuff
AND [ProductId] = Acer
Any idea's on how to make this quick? or quicker?
My Current runtime for calculating the 2500 base scores (totals 100 000+- rows) takes 15 hours. Though this is an initial calculation and is only supposed to be done once.
Also, this calculations are all correct, so my only issue itself is the speed of the entire process.
Thanks In Adance

Hi,I have a table defined asCREATE TABLE [SH_Data] ([ID] [int] IDENTITY (1, 1) NOT NULL ,[Date] [datetime] NULL ,[Time] [datetime] NULL ,[TroubleshootId] [int] NOT NULL ,[ReasonID] [int] NULL ,[reason_desc] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_ASNULL ,[maj_reason_id] [int] NULL ,[maj_reason_desc] [nvarchar] (255) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[ActionID] [int] NULL ,[action_desc] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_ASNULL ,[WinningCaseTitle] [nvarchar] (255) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[Duration] [int] NULL ,[dm_version] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_ASNULL ,[ConnectMethod] [nvarchar] (255) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[dm_motive] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_ASNULL ,[HnWhichWlan] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_ASNULL ,[RouterUsedToConnect] [nvarchar] (255) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[OS] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_AS NULL ,[WinXpSp2Installed] [nvarchar] (255) COLLATESQL_Latin1_General_CP1_CS_AS NULL ,[Connection] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_ASNULL ,[Login] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_AS NULL,[EnteredBy] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_ASNULL ,[Acct_Num] [int] NULL ,[Site] [nvarchar] (255) COLLATE SQL_Latin1_General_CP1_CS_AS NULL ,CONSTRAINT [PK_SH_Data] PRIMARY KEY CLUSTERED([TroubleshootId]) ON [PRIMARY]) ON [PRIMARY]GOWhich contains 5.6 Million rows and has non clustered indexes on Date,ReasonID, maj_Reason, Connection. Compared to other tables on the sameserver this one is extremely slow. A simple query such as :SELECTSD.reason_desc,SD.Duration,SD.maj_reason_desc,SD.[Connection],SD.aolEnteredByFROM dbo.[Sherlock Data] SDWhere SD.[Date] > Dateadd(Month,-2,Getdate())takes over 2 minutes to run ! I realise the table contains severallarge columns which make the table quite large but unfortunately thiscannot be changed for the moment.How can i assess what is causing the length of Query time ? And whatcould i possibly do to speed this table up ? The database itself isrunning on a dedicated server which has some other databases. None ofwhich have this performance issue.Anyone have any ideas ?

Hello! I have a query that join five tables and returns around 45000 rows that takes no more than a minute to execute, in management studio, on a SQL Server 2005, 2CPU 32 bit(dual core), 4GB and RAID5 disk system. The O/S is Windows 2003 sp2 Standard Edition.
When the same query is executed in SSRS2005, with some drilldown and summary of drilldown levels, it never stops to execute.
Looking at the hardware in the performance monitor reveals nothing strange except that % CPU-time is around 40 percent. Memory resources over 2 GB are available all the time.
Any suggestions is appreciated!
Any problems with SQL Server 2005 source database running on SQL Server 2000 compatibility level?

On a dual opteron server, viewing the properties of a task inside a data flow was immediate up until this morning.
We just installed SP2, rebooted, and now you right-click on any task and it takes between 30 secs and 5 minutes before the context menu pops-up.
The server is 99% idle, most of the 16 Gigs of memory are idle as well.

Hallo
i'm experiencing an extremely slow connection from a WXPP Sp2 client to a MSSQL2000 running on a W2k server. The client is running a VB6 application that connect with Windows authentication: every form requesting data opens with a long delay at the first launch; next attempts run normally fast.
In the same LAN there are some others identical clients, all running fine.
Every other network activity from that client is ok.
Where should i start to investigate from?

Hi folks,
I'm working within VS2005/Business Intel studio environment. I've got one master package, which loads about 18 sub-packages as tasks.
After openin the master package (and waiting 5-10 minutes for the packages to open and validate), maneuvering within the IDE is nearly impossible, it is so slow. Context menus can take 30 seconds to open. Certian operations, like closing a window, seem to hang the environment.
Does anyone have any feedback about this kind of ide performance problem?
Thanks, Scott

but i wonder why every time i launch the management studio, it tooks forever to load... about 5 minutes.
When i right click on a table and click on view properties, it can takes up to 5 minutes to display the detail.
Is there any setting / configuration that i configured wrongly?

SSIS packages running slow on startup in 64 bit prod env. looks like it is taking lot of time (around 2mins) to validate the package. Delayvalidation is false (default); changing it to true didn't help. Any fix for it?
Executing packages using dtexec commad.
We have job packages which loads 10s of child packages in sequence using package execution task... taking hours to complete. Same are working fine 64 bit dev env.

Hello,
I have designed a quite small SSIS package and everything worked just fine .
Untill I moved the SSIS project folder to another solution folder and added whole solution to Visual source safe.
Since then opening the package for design has become unbelievably slow, debugging it even worse.
I think the cause is in moving the SSIS project folder. But I have no idea how to fix this.
Any suggestions ?

We have been working with SSIS for a while and we have not found a solution or a reason for this. We have a master package that calls 10 packages in sequential order. (as shown below). If we execute each one of the package separately the run in less than 2 minutes, but when we call them through the master package the execution time start increasing as follows: Child 1 (2 min), Child 2 (3 min),, Child 3 (4 min), Child 4 (6 min), Child 1 (7 min), and so on. The execute package task has the ExecutionOutOfProcess = false (when we set it equal to True even takes longer to execute, it was creating a dtsHost.exe process for each child and always remain in memory after the package finished executing). Can someone please provide a solution or a workaround for this? Any help would be appreciated. Any help will be appreciated.

I have a parent package which executes 14 child packages in parallel, which on average take ~10 seconds each to complete when I execute the parent packege using BIDS or DTEXEC.
However, if I run the parent package using SQL Management Studio (Integration Services > Stored Packages > MSDB > Right Click > Run Package) each package takes in excess of 10 minutes to run, getting progressively slower as each package starts.
Surely the package is executing in exactly the same way as BIDS/DTEXEC, just a differenct UI?
Can anyone explain why this happens?
Thanks in advance,
Leigh

Hello all,
We have noticed in our environment slowness when starting SSIS packages from SQL Server jobs. I did a quite detailed study on when the slowness actually occurs and what are the consequences. Here are the results.
The SSIS package execution is slow if all the following is true:
The package is started from a job. If started directly as a SSIS package, the execution is fast.
The job is running on a 64 bit Windows Server (SQL Server 2005 SP2). The SSIS package and the job are either on the same server or on different servers (the second server is SQL Server 2005 SP1). If the job is run on a 32-bit workstation (Windows XP SP2) the execution is fast (the SSIS package still being on the server).
The package contains tasks.
§ If there are no tasks, just an empty sequence container, the execution is fast.
§ If a package that has no tasks has logging into the database configured, the execution is fast.
§ Slowness has been verified with A) a package having a single Execute SQL statement and B) a package having a Send Mail task.
It doesn't seem to matter which user account is used on when running the job.
The slowness happens in several locations, e.g. (there are also others, at least the following have been verified)
There is exactly 30 seconds lag between starting the job (as seen from job history) and when PreValidate (as seen in the sysdtslog90 table) of the package appears in the log.
The validation of the package takes 15 seconds (the time difference in the log betwen PreValidate and PackageStart)
The problem is really affecting our production environment. Currently the only solution we have come up is to put all the jobs on a workstation and use the workstation as a production server for the jobs.
I haven't heard anyone else having the same problem.

Hi,
I have created a package that has
2 SQL Execute Task, One Loop container, 2 Data Flow tasks, 1 Foreach loop container, 1 ftp task. The data flow tasks has 1 oledb source, 1 flat file source, 1 row count transformation, 1 recordset destination and 1 oledb destination.
When I load the package into BIDS it takes 125 MB of memory and then everything is slow, the properties panel slides in slowly and exists slowly. The object is the packages are not painted properly. to make changes and run takes lot of time.
Am I doing anything wrong here? Why is it consuming so much of memory?
Thanks in advance for your help.

I have a package with two sequence containers, each containing two SQL tasks and a data flow task, executed in that order. I want to encapsulate the data flow task in a transaction but not the SQL tasks. I have the TransactionOption property set to 'required' on the data flow tasks and 'supported' on the SQL tasks and the sequence containers. When I run the package I get a distributed transaction error on the first SQL task of the second sequence container:
"[Execute SQL Task] Error: Executing the query "TRUNCATE TABLE DistTransTbl2" failed with the following error: "Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly."
The only way I can get the package to succeed is to set the TransactionOption = 'required' on the sequence containers and 'supported' on all subordinate tasks. This is not what I want, however. Any ideas?
Thanks,
Eric

I had a Send email task linked to my Sequence Containers in my package and it was working fine. Everytime the container fails it would send an email to myself.
At some point all Failure constraints stopped working. Failure constraints work if I add brand new tasks, but with the existing tasks, they don't work. The Task which fails, turns red and execution stops. Next failure task is not executed.
I am not sure what triggered it to stop working. I cannot get anything on the log
Any help is appreciated.

Hi,
I am very new to SQL, and am basically self-taught(apart from SQL for Dummies and a couple of other books). I am hoping someone can help me with the 'CONVERT' statement.
My system outputs the date format as '12345'. What I have written so far is this;
select Resprj.Re_code, Res.re_desc, resprj.Pr_code, projects.Pr_desc,Res.Re_status1,
Projects.active, Projects.Pr_start, Projects.Pr_end
from res inner join Resprj on (Res.Re_code = resprj.Re_code)
inner join projects on (projects.PR_code = resprj.Pr_code)
and Projects.Pr_desc like '%C9%'
where projects.active =-1
order by Projects.Pr_code, Res.Re_desc
Could someone please help in regards to using the 'CONVERT' statement to change the date from '12345' to dd/mm/yy.
Thanks

I have a dataset that is between 40-50K records that has to go through a process that is pre-defined. SSIS works just fine with the smaller sets even up to 20K but this job keeps blowing up saying something along the lines of cannot write to recordset destination. Does this make sense to anyone? The sever is a 2 processor with 2GB of ram. Physical memory usage spikes to about 1.6GB during the run but the processor never really gets above 30% usage. Does this product just not scale yet?

I notice when I copy an SSIS package 'A' to a new package 'B', the new package 'B' will generate a "login failed for user" message in the data flow components. To copy I "save copy of Package 'A' as."
Some config info:
Package ProtectionLevel = EncryptSensitiveWithPassword
Connections are Data Sources
Connection strings with password are stored using PackageConfigurations to an SQLServer table. I've verified Package 'A' is in fact using the config table (e.g. it is not using a password or user stored in the package)
Data connectios are all SQLServer Native OLE DB Client
The account is an SQLServer account (not integrated security)
The original Package 'A' works flawlessly and I get success when I test the connections in Package 'B'.
But executing package 'B' I get: The error message I get is: [Connection manager "MyConnection"] Error: An OLE DB error has occurred. Error code: 0x80040E4D. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E4D Description: "Login failed for user 'dwuser'.".
Does anyone know why this would occur and/or how to work around it? I saw another thread where a potential workaround is to create a new data flow task and copy all the data flow components to that task. That won't work well for us because the data flow is moderately complex and when you copy and paste it, SSIS completely re-orders the layout.
This is a typical data warehouse ETL setup where there is a master package that executes child packages (e.g. 'A', and 'B' mentioned above) that each perform the ETL for a specific dimension or fact table.
Thanks for any help,

I have a test db in SQL Server Express 2005 with a 65MB dat file and a 1.1GB log file!! The production db has a slightly larger dat file and only a 6MB log file. I haven't updated by test db from the production db in a couple of months.
I tried Shrink Database and Shrink File in the Management Studio Express, but the log file size hasn't changed.
How did the log file get so large and how do I fix it?

Hello everyone,
I'm not sure if this is a problem but I've got a database which is about 1700mg in size (at least that's the allocated space on disk) and the log file is over 4600 mb. I've truncated the log file but it still keeps growing. None of our other databases are this large and there are a lot of transactions performed regularly but it looks odd to me that the log is this big when the data is half the size. How can I find out exactly how much space is being taken up by the data and is there anything I can do that will shrink the size of the log file? I am not really a dba so I'm not sure how crucial this is in the grand scheme of things.
Thanks

Right, I'm no SQL programmer. As I type this, I have roughly the third the hair I had at 5 o'clock last night. I even lost sleep over it.
I'm trying to return a list of records from a database holding organisation names. As I've built a table to hold record versions, the key fields (with sample data) from a View I created to display this is as follows:
record_id-----org_id-----live-----version
====== ===== === =====
1-------------1----------0----------1
2-------------2----------0----------1
3-------------1----------1----------2
4-------------2----------0----------2
as you can see the record id will always be unique. record 3 is a newer version of record 1, and 4 of 2. the issue is thus: i only want to return unique organisations. if a version of the organisation record is live on the system (in this case record id 3), i want to return the live version with its unique record id. i'm assuming for this i can perform a simple "SELECT WHERE live = 1" query.
however, some organisations will have no live versions (see org with id 2). i still wish to return a record for this organisation, but in this case the most recent version ie version 2 (and again - its unique record id)
in actual fact, it seems so much clearer when laid out like this. however, i feel it's not going to happen this end, and so any help would be greatly appreciated.
many thanks in advance,
phil

I have a dtsx package that works fine with one exception. When I open the dtsx package in BI, it gives me the following message:
Document contains one or more extremely long lines of text. These lines will cause the editor to respond slowly when you open the file. Do you still want to open the file?
When I respond yes, the package opens and I can edit or execute with no problem. Still, I want to understand what could cause this message to occur and, more importantly, how I can get rid of the message. When I try to simply execute the package I still get the same error and it seems this will be a problem for trying to run the package from SQL Server agent.
It seems likely to me that this message refers to the dtsx file (in xml format) itself. Does that make any sense?
