Package Too Slow On Startup
Nov 29, 2007
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.
Prod env:
Windows 2003 SP1
SQL Server 2005 SP2
Thanks

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.

I have two pages on a particular website that are data driven by SqlExpress. The site is in the testing stages, so there is very traffic on the site at this point. The very first time that a data driven page is accessed, the response time is approximately 30 seconds. After that, the response on the data driven pages seems normal. The data queried is no more that 30 or 40 records.
I did see the "slow startup from idle" thread on this forum - that thread suggested changing from user instances, but that's not an option here.
My hosting service requires that I specify user instances in my connection string. Is this just something that I'm going to have to live with, or is there any way to speed up this SqlExpress "start up"?

We seem to be having a rather strange issue. We just
finished migrating from 2000 to 2005. I've been working on converting packages
from DTS to SSIS. Everything has been going well in testing, but a problem has
shown up going into production. The first package I deployed ran significantly
slower on the production server, going from about 7 seconds to 90 seconds. The
production server is much more powerful, so this was rather confusing. The
major difference is that the server is running 64 bit.
After searching around, I haven't found much that is helpful. To test things
out, I created a blank package that does absolutely nothing. All it contains is
a single connection manager (OLE DB). Executing this package takes 45 seconds.
If I remove the connection manager, it executes in 0.1 seconds. Setting
DelayValidation to TRUE has no effect. If the connection is to a nonexistent
server, or if an incorrect login is used, the execution time is still 45
seconds. Adding a second connection manager increases execution time to 75
seconds. The package runs on my local computer in 0.1 seconds.
Any ideas what could be going on here? I cant believe that
no one would have seen an issue like this. Is there some sort of strange
configuration issue going on here?
Thanks in advance.

database : MS SQL server ver 6.50.201
problem: server startup / server time out
details
SQL server shows usage of 100 % CPU utilization, if started automatically / manually. and does not proceed / hangs up(server time out), but win nt operates extremely slow.
The background of the situation in brief is as stated below.
The errorlog was found to have the messages
warning : OPEN OBJECTS parameter may be too low.
Attempt was made to free up descriptors in localdes()
Run sp_configure to increase parameter value.
Error : 644, severity : 21, state; state 1
the non clustered leaf row entry for page 2 row 1 was not found in index page 40 indexid 2 database 'tempdb'
Error : 2620 severity 21 state 3
the offset of the row number at offset 32 does not match the entry in the offset table of the follwoing page : page pointer = 0x1395800, page no= 40, status = 0x2, objectid = 1, indexid = 2
Action taken
I used the sp_option to increase the open objects from default 500 to 1000, and the LE threshold maximum value to 400 from the default 200.
after which I used reconfigure go and restarted the computer to take the effect. The following did work fine and server was working ok. But then from yesterday I am having the problem that the MS SQL sever is utilizing the cpu to 98 - 99 % and I am not able to connect to the server.
I tried to start the server with the minimal configuration by specifying the -f option in the service manager start up options, it showed the following message
00/12/07 10:40:49.73 ods Unable to connect. The maximum number of '5' configured user connections are already connected. System Administrator can configure to a higher value with sp_configure.
00/12/07 10:40:50.02 ods Unable to connect. The maximum number of '5' configured user connections are already connected. System Administrator can configure to a higher value with sp_configure.
afterwhich I tried with the option of starting the sql server with the option -c -f
which in the event detail of the win nt shows
"mesg 18109: Recovery dbid 6 ckpt(55813,8) oldest tras= (55813,0)"
The open procedure for service "MSSQLServer" in DLL "SQLCTR60.DLL" has taken longer than the established wait time to complete. The wait time in milliseconds is shown in the data.
DB-LIBRARY error - SQL Server connection timed out.
and in the errorlog present in MSSQLLOG directory
00/12/07 15:06:43.24 spid1 Recovering Database 'master'
00/12/07 15:06:43.31 spid1 Recovery dbid 1 ckpt (7944,28) oldest tran=(7944,0)

00/12/07 15:06:43.50 kernel initializing virtual device 2, D:MSSQLDATAAMLOG.DAT
The dbid is / was 6 for both the instances, the database which is having this dbid is database name "AM" and is having above 1300 tables (approx)
what could be the problem and solution for it?
kindly help me out of this situation.

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 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?

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

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.

We have a STD SQL2000 with 2GB memory, which has around 800 databases and is planed to have 1500 databases.
From Microsoft Knowledge Base Q316749, <<By using the -g startup parameter, you can instruct SQL Server to leave additional virtual memory available so that the combination of these log-related allocations and other normal allocations does not run out of virtual address space.>>
but we are not quite sure the correct sytax, so we added -g392 and -g 392 as two new startup parameters. After reboot, in the error log, "initdata: Warning: could not set working set size to 765696 KB.
1. Is this a good way to increase the virtural memory?
2. which system table contains the -g value? and how to fix this error?
thanks

Running SQL2000/SP2. DB has approx. 750,000 rows in main table - 500 MB content. Db is set To Truncate on Checkpoint, so no Log file to speak of - ever. System is 667 Mhz PIII with 512 Mb Ram. Disk are ATA133.OS is W2k Server-SP3. Anonaly happens at System startup. Db is coupled with automatic data collection software for manufacturing. It is taking DB longer and longer to "catchup" after each boot. Pref Counters show main problem is Disk Read Queue Length. (CPU % doesn't exceed 40%, normally 7% - SQL was given 1/2 RAM - 256 MB). If Data Collection is not started, DB comes up rapidly (it seems), but manual test inserts show high - protracted disk activity, but tests don't fail, just run slow. After a number of test inserts (7 - 12+), log jam breaks and the processing time drops from 1.5 Minutes to the normal 15-20 Milliseconds!. Similar action is seen with Data collection software running at boot. By design, the Data collection software buffers all inputs to the DB, so no loss, but the disk thrashing is disconcerting. This type of problem is not seen during normal operation (system is closely watched by automated scripts). Main table is routinely reindexed and fragmentation is tracked (never gets above 5% fragmentation). No table is 'pinned' in RAM.
Hints, allegations, and out-right lies glady accepted!

Hi,
I am getting issue while Starting SQL Service.
Error started since I rebooted the server without stopping SQL Services.

3. TDSSNIClient initialization failed with error 0x57, status code 0x1.
4. Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.
5. SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.

I'm not familiar with SQL Server and am just starting things up. I have VB Express and SQL Server Express (I think - at this point, I wouldn't be surprised if I didn't), and am trying to create a database.
So how do I do that?
All I see that relates to the SQL Server 2005 is under All Programs -> Microsoft SQL Server 2005 -> Configuration Tools; I have a configuration manager, Error and Usage Reporting, and Surface Area Configuration. I assumed that in there would be a database engine in here somewhere, but I have rumaged through every command in these and found nothing on creating a new database. Nada.
Am I looking in the wrong places, did something go wrong with my install, or am I just a complete leptic?
Please Help!

Hi,
Is there any way to use different email accounts for sql mail dynamically on sql server 2000?
Here is the problem:
My sql server is configured to start mail session under account 'xxnotifyxx'.
There are many jobs scheduled to run queries and send out emails to different user groups within the company as well as outside the company from 'xxnotifyxx' as a sender.
However, one of the usergroup within the company is asking for sending out their emails ( from scheduled tasks that uses xp_sendmail ) using 'publishergroup' as a sender.
As far as I know, this is not possible (sql server 2000, exchange 2000 client win2000 ) until I change the mail session configuration to start under 'publishergroup' in stead of 'xxnotifyxx'. If I do this, 9 other groups have problems with this.
Is there a work around for this kind of situation?
Thanks,
Shaili

I have the following stored procedure set up as a startup procedure in the master database. I was lead to it from a microsoft SQL server news group and I have found that it is very helpful. I have been told, though, that it only runs on the master database at startup, but I need it to run for all of the databases on my server. (I'm a newbie and can't follow the code myself). How can this stored proc be modified so that it runs on all of the databases on my server at startup.
Any help is greatly appreciated. Thanks in advance!

I'm new to SQL Server....running SQL Server 2000. Had to move the system database logs to a different drive. Used EM, Server properties, Startup parameters. Changed the transaction log designation. Closed that window. Stopped the server.
Server won't start as I messed up and did not include the file name in the new designated path....just down to directory level.
From what I've seen, I have to be able to start the server service to change the parameters and the server won't start.
Is there a file that contains these parameters I may edit or should I try using the command line options.
Many thanks in advance.
