The Best Methodology To Test Load Script

"I have build a long sql data load script. What is the best way to do
Testing of the script? I would like to automate the test!"
I need to create a test load a MS SQL Server 7.0 server of 250 users.
Does anyone know of any application(s) that can do or any processes
that can mimic a load such as this?
Hi all,
We are using temp tables (loacal Temporary tables) in our business logic(stored procs).During the load test , the temp DB log gets full.How to avoid this?.
Thanks in advance.
Hi everyone -
I'm stumped on what to cal this, there might even be
a method or pattern named for what i am trying to accomplish...
In the database, a number field is included on each table
When the DAL reads the record from the database, it is passed to
the client - work is possibly done to the record and is sent
back to the DAL for update.
A query is done against the table to retrieve the record again,
the numbers are compared - if they don't match, it is assumed the record
been modified by another user/thread/activity. An error is returned to the client stating the data has been changed.
if the numbers match, the record is updated with the number field being incremented by one.
what is this methodology called (beside crap :-) )
thanks

Hi,Our DBA group is debating production release methodology. We alwaysperfect our deployment package (typically a script) against thedatabase in a Staging environment, before executing the packageagainst Production. One side argues that the safest approach is tocreate a script containing all schema changes, data changes, storedprocs, functions, etc. Run that script against Staging until it iserror-free. Then, when you run it against Production on Release Nightyou know it will also be error-free, since Staging is a copy ofProduction. However, any changes to the deployment, such as updatesto procs (and there are always a bunch in the pre-deployment period)must be manually implemented on the script.The other side wants to take advantage of the .NET environment. Wekeep all procs, views, and functions in a Release folder on VSS,execute a Get Latest Version (Recursive) from VisualStudio, and runagainst Staging/Production. Any changes to the procs areautomatically propagated from VSS to VS, and there is no manualediting of the script. You still need a script for table and datachanges. The "script everything" side of the debate feels this methodis not as reliable, especially since when views are nested, you willget compile errors and must execute the run-on several times until allthe views compile. The "script" side feels that any errors areunacceptable in a Production environment.What is the opinion out there?Thanks!
View 5 Replies View RelatedWe are setting up a test lab environment with 100 machines. We want one master testing db that gets replicated to each to run scripted application tests nightly.
My goal is to minimize the amount of work to move this thing to each of the 100 test machines. I am wondering if we need to even have the sql local and invest in a monster db server with 100 copies of the db we restore and each test machine point to their own db on that server, or if I should use db mirroring or something to get the master test db to each of those machines instead.
Now that we have a good programming model in SSIS - the question is whether to write automated unit tests for your packages, and would it generally be a good idea for packages?
Also - if yes to write tests - then where to find more informations regarding How to accomplish that?
hi every one,
i need to test SSIS pacakge which will import data from different database where record count is around 5 millions.
iam planning to test it through c# code as well as manually also.
SSIS source : consist of 7 tables
SSIS destination :consist of 7 tables
Using c# code iam trying to run ssis package through batch file.
i am putting expected rowcount, column count in an excel file and comparing same with destination tables by writing query implementing ADO.Net concept.
am i going right way ,can any one suggest best and productive way to test the ssis package .
what are the other things i need to test it.
do any one can add test cases to it.
S.No
Test Case
1
Verify all the tables have been imported.
2
Verify all the rows in each table have been imported.
3
Verify all the columns specified in source query for each table have been imported
4
Verify all the data has been received without any truncation for each column.
5
Verify the schema at source and destination
6
Verify the time taken /speed for data transfer
7
Fields truncated due to difference in length of the field at destination.

Here I will describe my problem.
1. We are loading large amount of data from database on background thread which is starting on Application_start event in global.aspx.cs file.The data is later cached for subsquent request to improve the performance.
2. Now when we put the application on web farm garden, it is not able to load the application.
3. We are sending the request the servers through Router kind of application.
4 This application is working fine on single server enviornment.
Please help us.

I just have done the SSIS example in the tutorial document included when install SQL 2005 ENT. I have a problem that whenever I test to run, the service load all data from source with out noticing about the data (I mean it load all the data to the destination), I do it several time and it continue to load all without checking. That mean the data is dublicated when the schedule run???
I think there should be a paramete or something like that to help the engine just load the new data to the destination. Could you help please?
Thank
Hello,
I have a big problem and i'm not able to find any hint on the Network.
I have a window2000 pc, VS2005,II5 and SQLServer 2005(dev edition)
I created an SSIS Package (query to DB and the result is loaded into an Excel file) that works fine.
I imported the dtsx file inside my "Stored Packages".
I would like to load and run the package programmatically on a Remote Scenario using the web services.
I created a solution with web service and web page that invoke the web service.
When my code execute:
Microsoft.SqlServer.Dts.Runtime.Application.LoadFromDtsServer(packagePath, ".", Nothing)
I got the Error:
Microsoft.SqlServer.Dts.Runtime.DtsRuntimeException: The package failed to load due to error 0xC0011008 "Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored.". This occurs when CPackage::LoadFromXML fails.
The error message doesn't help so much and there is nothing on the www to give me and advice....
Is it a SSIS problem???
Thank you for any help!!

I am currently utilizing the checksum function to generate a hash that I later compare to detect changes in a row.
CHECKSUM(field1, field2, field3, field4)
Now I'd like to use the HashBytes function instead over the same fields. But the HashBytes function accepts only one data value. What is the most effective and reliable way of getting an MD5 over several fields?

Hi.
I have an application where I allow users to type in their SQL queries. Before I store those queries I have to make sure that they are correct, both syntax-wise and data type-wise. For that I execute the query against the database and trap any errors that may be returned and that's how I judge if the query was OK.
In order to keep this test as quick as possible, I tried to add a WHERE clause to it like: WHERE 1=2, so no results are returned. But then I discovered that the addition keeps errors from happening if they are of ata type nature.For instance "select orderid + 'test' from orders where 1=2", run against the Northwind database, returns no errors, while OrderID is numeric and U'm adding a string to it!
Next, I tried to return only one row: "select top 1 orderid + 'test' from orders". This time the error is thrown, however the query still takes a looong time when run on a huge table. I don't kknow why that is, but it seems that the engine runs the query for the entire table and then gets the first row!
Does anyone have an idea ehat's happening or have a better suggestion on how I can perform my test without killing the database?
Thanks.
I have a stored procedure which runs a query, then turns it on its side (so that the rows are column headers).What I need to do now is test if any of the values in a row from this stored procedure are null.Any suggestions on how to get started? Is there some function that will tell me if any value in the row is null?

Hi -
I'm having a problem with a VB6 program I'm writing that posts data to a SQL server. The problem occurs when the SQL server is unavailable. When this happens it causes the program to hang for at least 30 seconds before releasing. The hang happens at the code that connects to the SQL server, because the server isn't there. I've added code found on this site to test the connectivity prior to making my actual data connection, but this causes the same hang. Is there any way to verify connectivity to an SQL server without actually trying to make the connection? I'm really trying to eliminate the hang that occurs when the server is unavailable.
Thanks
I have gotten some criticism from coworkers regarding this test and just wanted to see what you guys think. I realize the wording could use improvement and any criticism towards making it easier to understand is much appreciated.FWIW - I had to solve this problem on the job so I feel it is a real-world test that helps me understand how people think and if they try to find alternate solutions.Thanks!~~~~~~~~~~~~~~~~~~~~Given a table that has over 100,000 records…SUBSIDIARY=========PARENT_IDINTCHILD_IDINTULTIMATE_PARENT_IDINTCLEANUP_INDBIT…where each PARENT_ID can have multiple CHILD_ID values, but the PARENT_ID should not equal the CHILD_ID. After an initial data load, the ULTIMATE_PARENT_ID and CLEANUP_IND columns contain NULL values (see page 2 for sample data).ULTIMATE_PARENT_ID is defined as the topmost parent in the chain for the particular CHILD_ID record, so if the chain was only 2-level’s deep the ULTIMATE_PARENT_ID is the CHILD_ID’s PARENT_ID’s PARENT_ID.Please write an answer for all three questions below:A)Which of the following queries should you run first?B)Write an optimized query to identify the ULTIMATE_PARENT_ID for each CHILD_ID and set its value into the ULTIMATE_PARENT_ID column.C)Write a query to identify ALL of the circular references and mark each record that is a circular reference by updating the CLEANUP_IND column to 1.~~~~~~~~~ Page 2 ~~~~~~~~~ Sample Data, remember though this table has over 100,000 records and the parent-child chain can go n-levels deep – where n is not known.PARENT_IDCHILD_IDULTIMATE_PARENT_IDCLEANUP_IND1024512NULLNULL362300NULLNULL887541NULLNULL10221024NULLNULL546887NULLNULL5122305NULLNULL112967NULLNULL697123NULLNULL901452NULLNULL2300666NULLNULL334445NULLNULL512903NULLNULL884554NULLNULL313313NULLNULL554884NULLNULL112119NULLNULL967555NULLNULL2305333NULLNULL33336NULLNULL541546NULLNULL10301020NULLNULL112999NULLNULL

View 7 Replies View RelatedHi,
Whats the best way to test scalability on a database? I'm working on a new app, and have handed off developing the database to someone with more experience. Some tables will grow to many million records, and I don't want it to bottleneck. I need to have it fully tested before it goes live.
Is it reasonable to ask the person helping me to fill it with 10's of millions of rows to test performance? Is this a decent solution? If so, what would the best way to fill it be? If not, what steps should I take?
Thanks very much!

Hello All
We have Asynchronous DB Mirroring established for our Production database
which runs on SQL Server 2005.
For the DR Test we plan to do the following during the period of low activity :
1. Pause the mirroring on the Principal Server.
2. Break the mirror on the Mirror Server
3. Take on offline backup on the Mirror.
4. Bring the Mirror Database up.
5. Run the DR Tests on the Mirrored Database
6. Restore the Offline Backup taken in step 3.
7. Reestablish the mirror from the Principal to Mirror.
8. Resume Mirroring on the Principal Server.
9. Verify Mirroring is happening on the Mirror Server
Can u please let me know if this plan is feasible and if there should be any modifications to the plan that are required. Any other suggestions/input is appreciated.
TIA

Thank you so much.
Is there a way to manually run a subscription? I have a report with an email subscription. The only way I know of to test it is to set the schedule for a minute or two in the future and wait for it to run. Is there any way of telling the subscription to "run now"?
For that matter, how can I run a subscription manually from a Stored Procedure?
Thanks,
