Dynamically Setting A Checkpoint Filename

Mar 14, 2008

I am trying to dynamically set the name of a checkpoint file and I have used expressions in the package property and evaluated the following expression correctly


Expression: "C:\CheckPoints\" + "CheckPointFile_ "+ @[User:BName]" + ".xml"

Evaluates as: C:CheckpointsCheckPointFile_@[User:BName].xml

when I try to save the package, it comes up with an error saying

Error at Caller Package: the filename is not valid. the filename is a device or contains invalid characters.

Anyone know why?

Get Filename Dynamically

Jul 26, 2007



Hi,
Using a ssis package I have several tasks.
A variable is also created called FileName.
There is a flat file connection called InputFileName.
initially when I designed the package, I hardcoded the pass of one of the .csv files into the path of the flatfile connection.

There is a dataflow which has flatfile source and oledb destination. These two basically pickup the file and import into the database using mapping.

So therefore the package works and data gets imported into the database.

Then I used the variable to make the filename dynamic. So I removed the hardcoded connectionstring in the InputFileName.

Is this the right thing to do to make the package dynamic? I would like to pass in any .csv filename and so the package runs.
My question is now that the connectionstring is deleted but instead placed an expression for the filename, then how does the system know which file to use?

Thanks

Now i want the file name to be appended with the date and time of package execution. So the filename will be something like ; Filename_MMDDYYYY.txt.



How can i do this with the help of SSIS?

Anyone having an idea would be of great help.

Setting DTS Connction Object Dynamically

May 12, 2006

Hi:

I have posted concerning this-I don't mean to double post but I have
isolated the problem and have new information. (and I'm desperate!!) Please direct me to a DTS forum if this is not the place for this, I didn't see one.

I am trying set the data connection object (ODBC to Sybase) twice in
the same package but the Data Pump Tasks that use this connection don't
seem to be using the new setting in the connection after the second
time it is set, although at the end of the package I can see that the
connection has been set. The pumps just use the original connection a
second time instead of using the 2nd connection.

Here is the progress:
1. SQL Task1: Gets server information from a SQL Server table, and sets
it to a recordset global variable in the DTS.
2. ActiveX Task1: Begins loop, and sets the connection to server2 and
sets sql of datapump tasks
3. Several data pumps run.
4. ActiveX Task2: just loops around to ActiveX Task1
5. ActiveX Task1: Sets the connection object to server2 (msgbox tells
me this happens successfully)
6. The datapumps continue to use server2(??)
7. Package finishes succesfully
8. I right click on first datapump and do a "execute task". It executes
using server2, which for some reason it did not do during execution of
the entire package.

The loops works fine (as I have gotten it from you Allan), it clearly
goes through twice when I have specified two servers (I can see the
data in the resulting table is doubled from the source server, and I
can see it in the progress window going through the data pump steps
twice). After, if I run the data pump tasks by right clicking and doing
an "execute task" then it works using server2 was set.

I put a msgbox in the ActiveX Task1 to confirm the server is being set
correctly.

Any ideas here? Is there some other property I need to set? Is it a
setting with the Data Pump task? This all seems very weird-I feel like
I must be missing something obvious.

Here is the part of the code of ActiveX Task 1 (only part) that sets
the connection (let me know if you want to see the package):

Dim pkg
Dim SCCScon
Dim objRS
Dim SQLStatement

set pkg = DTSGlobalVariables.Parent
set SCCScon = pkg.Connections("Connection_Name")

set stpEnterLoop = pkg.Steps("DTSStep_DTSDataPumpTask_1")
set stpFinished = pkg.Steps("DTSStep_DTSActiveScriptTask_5")

Set objRS = DTSGlobalVariables("gvDataSources").Value

stpFinished.DisableStep = true
stpEnterLoop.DisableStep = false
stpEnterLoop.ExecutionStatus = DTSStepExecStat_Waiting

msgbox "DSN is now: " & SCCScon.DataSource

SCCScon.DataSource = objRS.Fields(1)
SCCScon.UserID = objRS.Fields(2)
SCCScon.Password = objRS.Fields(3)

msgbox "Now I've set the DSN and it is now: " & SCCScon.DataSource

SqlDataSource SelectCommand - Dynamically Setting The Name Of The Table?

May 7, 2007

Can you dynamically set the name of the table in the SelectCommand section of the SqlDataSource? (If it is relevant, I code in C#)
 For example,
<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:Test-MySQL %>" ProviderName="<%$ ConnectionStrings:Test-MySQL.ProviderName %>" SelectCommand="SELECT * FROM TestTable">
I would like to replace 'TestTable' with the name of a table that is extracted from a string array in the code-behind.

Setting Default Value Of A Report Parameter Dynamically

Jan 26, 2007

Hi all,

Does sombody have experience on dynamically set or change the default value of a report parameter?

Assuming: report parameters p1, p2, p3, p4 have been set up(and have their default value 'all') with the creation of the report1; report browseing is through reportviewer that embedded in the web application; datasource is datacube

What I want to do: based on the login user of the my web application, set default value of p1 as the user's username.

What I did is:

Microsoft.Reporting.WebForms.ReportParameter reportParam = new Microsoft.Reporting.WebForms.ReportParameter("P1","Mary");

ReportViewer1.ServerReport.SetParameters(new Microsoft.Reporting.WebForms.ReportParameter []{ reportParam });

what I got when reveiw the report:

P1 has no default value, and p2, p3, p4 greyed and could not choose value from them.

Any idea and suggestion will be pre-appreciated!

Setting SqlDataSource Update Command And Parameters Dynamically C#

Aug 31, 2007

Hello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
 
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">
<UpdateParameters>
<asp:ControlParameter Name="USERNAME" ControlId="txtUserName" PropertyName="Text"/>
<asp:ControlParameter Name="SERVICE_TAG" ControlId="txtServiceTag" PropertyName="Text"/>
<asp:ControlParameter Name="TECH" ControlId="txtTech" PropertyName="Text"/>
<asp:ControlParameter Name="DESKTOP" ControlId="txtComputerName" PropertyName="Text"/>

Dynamically Setting Connection String Depending On Server_name?

Apr 18, 2008

I need to make my site aware of which server_name it is loading from so it uses a different connection string. (have dev + prod servers for web/sql)Currently my connection string is in web.config as follows:  <connectionStrings>      <!-- Development and Staging connection string -->          <add name="myconnection" connectionString="server=myserver; user id=mysuer; password=mypassword; database=mydatabase" />   </connectionStrings> I need to make sure the 'name' is the same for both connection strings since that is how the rest of my site looks for it.  However, I'm not sure how to get both in here with some sort of 'if/then' statement to determine which one to use.I've heard it could be done in global.asax with something similar to the code below, but I dont know how to assign a 'name' to a connection string for that type of setup. Sub
Session_OnStart  ServerName =
UCase(Request.ServerVariables("SERVER_NAME"))  IF ServerName = "prod.server.com" THEN   ...Set Prd string...  ELSE   ...Set Dev string...  END IF  End

Hi all
I hope someone can help me on this issue:
I am designing dynamical reports, that are abel to run in four different languages - so far everything works just fine for me (I select my headers and labels from a database). Only problem is the prompt text for report parameters. How can I set this text dynamically?

Setting Expressions In Datareader's SQLCommand Property Dynamically

Sep 19, 2006

Hi all,

I have been playing with integration services for a few days and at the moment, its up there with my list of software that I find ......painful.

What I am trying to do is read different tables from my one SQL database, then populate my Access database with its data.

I have put a foreach loop which goes through a collection SQL statements that I have entered into it. It first assigns it to a string variable called tablenameVar which contain statements such as "Select * from Terminals". Then the datareader is supposed to execute it based on the connectstring which never changes, and the SQLCommand value which I passed using the variable @[User::tableName]. However when I try to run it, I'm getting this error.

Checkpoint Restart

Jan 24, 2006

I have a package that uses checkpoint restart. It is resposible for truncatings many sets of tables and then loading them. There are several ExecuteSQL tasks to truncate the tables and several corresponding data flows to accomplish the loads.

If a load fails I want the corresponding truncate task to be part of the restart otherwise duplicate data may be loaded. Normally, SSIS will start at the failed task. I read something about containers that led me to think that if I put the truncate & matching load pair in a sequence container that the container would be the restart point, but either I read it wrong or it's not working that way.

Anybody know how to accomplish what I want to do?

Unreliable Checkpoint

Nov 27, 2006

With 2005 SP1. Have built a SSIS package that successfully saves a checkpoint file and sometimes successfully restarts. (I've also built some others that are 100% reliable).

On the unsuccessful restart it appears as though the failed steps and subsequent steps do not execute. the package appears to "complete" though and the checpoint file is removed as though everything is fine.

On a successful restart the failed step reexcutes and everything works fine.

The issue appears that when a failed step finishes at the same time as a successful step finishes there is contention in the process that writes the checkpoint file out and the checkpoint file is corrupt. The failing step runs in parallel with a successful step and the execution times are very similar so task A may complete before or after task B.

Contents of a good checkpoint file follows <DTS:Checkpoint xmlns:DTS="www.microsoft.com/SqlServer/Dts" DTS:PackageID="{3BFFF2F9-74BA-4CE9-8435-81CC198E8144}"><DTS:Variables DTS:ContID="{3BFFF2F9-74BA-4CE9-8435-81CC198E8144}"/><DTS:Container DTS:ContID="{3655F83D-5EA5-4F16-9B8F-520582A1229A}" DTS:Result="0" DTS:PrecedenceMap=""/><DTS:Container DTS:ContID="{DB2D7A57-D405-4B11-AF4A-41B331EE3F15}" DTS:Result="0" DTS:PrecedenceMap=""/><DTS:Container DTS:ContID="{DFC6A95F-CCFA-4FD9-B604-FCBD722B47D8}" DTS:Result="0" DTS:PrecedenceMap="YYY"/></DTS:Checkpoint>

Checkpoint Not Being Set? Log Not Truncating?

Oct 26, 2007

Hi,

I've set up a number of jobs (not a maintenance plan) via a script in SQL 2005. These jobs do the following:

1) Full backup every sunday night
2) Differential backup every weeknight
3) Log backup every hour

The database is obviously in the full recovery model.

The backups all seem to be running, with one issue - the log file is still growing and is not being truncated. I was under the impression that a log backup should result in the log being truncated after each full backup. However, this does not seem to be the case.

Is there anything obvious I've missed that needs to be set up, or is there a way I can check that the full backup is actually setting the appropriate checkpoint and that the log backups are 'seeing' these checkpoints?

Thanks

Truncate On Checkpoint And Autoshrink?

May 9, 2002

Details: MSDE 1.0 / SP4 - Windows 2000 Pro

I have a database that has Truncate on Checkpoint set for the Log file. The Log file is set to AutoGrow. Is it necessary to to run dbcc shrinkdb (or the like) to get Log file to contract? Is there any harm in not contracting the Log file? I'm looking for best efficiency and least-likely-to-fail path as DB sits 'really remote' and there is little opportunity for observation.

Does anyone have any recommendations on re-indexing? I have one table that bears the most growth. It has a clustered index. What would be a suitable data point to watch? I run a SP to save DBCC SHOWCONTIG info along with the duration of a test query, but haven't seen a clear breakover point.

Truncate Log On Checkpoint Keeps Checking Itself.

Can anyone assist with this problem.
Every now and then my overnight backups (backup Exec) fail due to the truncate log on checkpoint being enabled. This occasionally occurs on Master MSDB databases. I have unchecked the truncate log on checkpoint box numerous times and the backups work fine. Then mysteriously the box is checked again and the backups fail once more. I am stuck as to why this can happen. Is there a generic stored proceedure that checks this box ?

Truncate On Checkpoint Not Truncating

Dec 30, 1998

The log on one of my databases keeps filling up, even though I have it set to truncate on checkpoint. the only real difference between this database and the others on my server is that it is built from the dump of another database (on another server) where the tables are marked for replication.

I'm wondering if the fact it is built from a replicating database could be causing this. I've noticed I can't drop any of the table, even though my database isn't set to replicate (or publish).

two questions
1) Any ideas?
2) Is there anyway I can make my server realize I'm not replicating so it will let me drop those tables? (nothing in Enterprise manager indicates that my database is replicating or publishing).


Thanks,
Jim

CHECKPOINT Backgroup Process

Apr 16, 2008

Hello,

I am DB Developer (not admin), excuse me if this is a silly question.

I don't know much about CHECKPOINT background But I feel, this process is slowing down performance of my sps which runs slower than normal in some cases.

Especially when I see any of my process goes in the suspended mode and its wait type is SLEEP_BPOOL_FLUSH and CHECKPOINTs process is also suspended and its wait type is CHECKPOINT_QUEUE.

More important anything else is... this background process (which I always find its spid is 11) BLOCKS all other user processes when it goes into suspended mode and its wait type is SLEEP_BPOOL_FLUSH

I dont know my analysis is correct (claiming checkpoint as culprit), need experts advice and help

can someone give info on checkpoint and how this effect server performance

Server Freezes While Doing Checkpoint ?!

Jul 24, 2007

We're running the Microsoft product SMS 2003 SP1 for software deployment, patching, hardware inventory, etc. The back-end is SQL 2000 Enterprise SP4 which is installed on the same box as the SMS 2003 SP1 product, and the DB is 145GB's.

We started noticing that the server would freeze every minute or so for 30 seconds. We started logging stats via perfmon and saw that the average disk queue length for the physical drive of F: would skyrocket between 400 - 500 for 30 seconds at the same time the freezing occurred. I have determined that this is occurring during the checkpoint. The recovery interval option is set to the default of 0 on SQL, when I changed the setting to every 5 minutes, the average disk queue length for the physical drive of F: would skyrocket between 400 - 500 every 5 minutes and would subside after 2 minutes. I understand the need for the checkpoint / recovery interval option, but don't believe this high average disk queue length should be occurring.

Does anyone know why this is happening and how to fix this ? The freezing of the box while checkpointing is killing me.

Thanks

Error When Trying To Use Checkpoint File

Jun 20, 2006

I have a package with settings SaveCheckpoints=True and CheckpointUsage = Never.  After the package failed I fixed the cause of failure by setting a database column to allow nulls.  Then I went to our web app that we built to monitor package execution and clicked on the button to restart the package.  The web app loads the package and then sets the CheckpointUsage property of the package object to 'Always'.  Then it executes the package in a new thread.  The package then produced this error:

Checkpoint file "E:Package1Checkpoint" failed to open due to error 0x80070005 "Access is denied.".

Since there was only one remaining task to run in the package I ran it manually. 

Now here is the really interesting part.  I then needed to run the same package but with different parameters.  When I attempted to run it with the saved checkpoint settings (CheckpointUsage=Never, SaveCheckpoints=True) I got this error:

"An existing checkpoint file is found with contents that do not appear to be for this package, so the file cannot be overwritten to start saving new checkpoints. Remove the existing checkpoint file and try again. This error occurs when a checkpoint file exists, the package is set to not use a checkpoint file, but to save checkpoints. The existing checkpoint file will not be overwritten. "

So I then attempted to rename the checkpoint file so it would not interfere, however, it would not let me, saying that the file was in use.

So what I had to do was add a configuration entry which set SaveCheckpoints to False.  Then I was able to run the package.

Any ideas?
