License Considerations For SQL Data Source Of Reports

Dec 10, 2007

I may be overthinking this, but I want to make sure this is right. If you have a processor license of SQL Server Standard running both Reporting Service databases and the IIS interface, isn't it true that the underlying licenses of other servers containing your data are irrelivent in the context of serving the reports over the web? Example. Server 1 has SSRS as described above, processor license of Standard. Server 2 has user license of SQL Enterprise and serves data to a couple of reports on Server 1. This does not violate a license, correct? Doesn't Server 1 just take one of the CALs from Server 2?

How Can I Automatically Edit A Reports Data Source?

Jan 5, 2008

Scenario:

I have 2 identical Analytics cubes, Cube 1 & 2, my reports point to Cube 1, when Cube 2 is refreshed the reports data source is manually repointed to the updated Cube 2. The following day the Cube 1 is refreshed and again the reports data source is edited and repointed back to Cube 1.

This ensures that if a cube build failes the reports aren't down.

To modify the data source I connect to Reporting Services using SSMS go to the Data source folder and manually edit the Data source.

I have looked through the Reporting database in SQL Server but didn't see anything that resembled the connection string for me to edit.

Are the connection strings for the Data sources stored in the Reporting Database ? Where can I find them?

Here is a Microsoft document that gave me the idea. http://www.microsoft.com/technet/prodtechnol/sql/bestpractice/scoqryas.mspx

It talks about changing the connections strings in the Web UI? But doesn't tell you how or point to any docs that do.

Is there a way to automate this and is anyone else running a similar setup.


I appreciate you help

Thanks

SQL Server 2005 Workgroup Edition Licensing (How To Install Without A License, Then Require License On First Run)

Oct 13, 2006

I have a VERY Legitmate use to install sql 4 workgroups on a pc without licensing it. I am making a disk image for MANY pcs to be imaged and load licensing after the imaging is completed.

I have been able to do this with Windows XP Professional, MS Office 2003 and a couple non-Ms programs. The information for MS software even came from their KB, so I know what I am doing is legit. I just can't find any information on doing this for my sql app.

Any suggestions??

How Do I Add An ODBC Connection Data Source As A Data Flow Source

Mar 2, 2007

I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.

Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?

Thanks in advance

FillFactor Considerations

Apr 19, 2007

I have a table with about 200 million rows of data. I add a couple million rows of data each week to the table in a single load process. The table is used for reporting purposes only and there are never (not intentionally at least) any updates or deletes to the table. The data is always being added to the "end" of the table with the new AsOfDate being the main factor in the clustered index.



My question is this: Since I'm not "inserting" rows that would split pages, should I have my FILLFACTOR for the table set to 100, or am I missing something? I obviously want to save physical hard drive space, but I also don't want to slow down the import process.



BTW, I'm using SQL2000

Cannot Create A Connection To Data Source 'data Source Name'

Dec 11, 2007

Today I was making a few reports.
When I tested the reports in Visual Studio, they worked great: I got the expected result.
But when I deployed the reports to our reportserver the problem started.
When I click on the directory in which my reports are deployed, I got my 4 reports.
Till now everything worked correct.
But when I click on a report to view the results it went wrong.
I got an error:
"Cannot create a connection to data source 'Live'"
(Live is the name of our data source).

We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work.
I also have tried it with all the roles assigned on my account, but then it still won't work.

When I modify the data source, and set it to another server en database it works.
The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server.
Maybe that is the problem?

Can someone tell me what is wrong?

Loading Data Using Ole Db Source With Input Source Being A View

Dec 13, 2007

I was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.

The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.

Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?

Network Considerations For Mirroring

Apr 19, 2007

I would like to know people's thoughts on any special network considerations to take for mirroring and the logic behind them. Is it best to segregate mirroring traffic from other network traffic? Use a VLAN? Dedicate one NIC for mirroring and the other for general network traffic or just aggregate the two and let both types of traffic share the bandwidth?



I haven't seen much in this area from Microsoft's best practices and wanted to know what those who have implemented it have done and why. There are pros and cons for each method: Letting everything share one massive pipe with load balancing vs. trying to segregate traffic in some way so that general network connections etc. do not impact the mirroring capability.



I look forward to hearing from you.

Integration Services Considerations

Sep 14, 2007



We have about 150 SQL servers and basically we're considering the pros and cons of installing SSIS on a central SSIS server - that is responsible for all DTS jobs - as opposed to installing SSIS on the local SQL instance.


On the plus side so far:


1./ Central administration, alerting, change management etc

2./ Possible performance gain on the local instance not having SSIS installed?



On the negative side:


1./ Central point of failure

2./ Possibility that it would need to be a clustered...

3./ Compatibility issues may mean having to make the central SSIS server 32-bit?

4./ Possible performance cost of remote SSIS?

5./ With multiple DTS packages running at different times, when would we take the server down for maintenace...?

Would appreciate your thoughts.

Database Mirroring &&amp; Replication Considerations

Jun 21, 2007

Hi all,



Can a publisher be mirrored? What are the implications, issues, gotchas? Transactional, Merge or Transactional w/ Updating Subscribers is what I'm considering.



Bottom line is I would like to use mirroring, but only one mirror will not suffice.



Thank you in advance.

Considerations When Delete Records From Table.

Nov 15, 2006

Hello, I'm developing application which monitors network packets. The monitoring data are saved into table. Monitoring table maintains the data for fixed quantum time,for example during one 1 hour. So, every minute before or after insert new data, I delete the time-expired data. I doubt that the endless delete operation would results in some problems(increasing index,etc..).

Is this mechanism safe to the dbms?

Aren't there round-robin(?) style table?

Instead Of Trigger Considerations For Multi-Row Insert

TRIGGER ON childtable INSTEAD OF INSERT

DECLARE @parent int;
DECLARE @date datetime;

SET @date = getdate();

SELECT @parent = parenttable FROM inserted;

SELECT @nextchild=count(*)+1 FROM childtable WHERE parenttable = @parent;

IF (@nextchild >= 9998) return;

SET @customkey = €˜type€™+ convert(char(4),year(@date)) + convert(char(2),month(@date)) + convert(char(2),day(@date))+convert(char(4),@nextchild + 1);

What Are The High Level Considerations For 24x7 Installations?

Feb 13, 2008

in a prior "legacy" life we couldn't imagine 24x7 implementations because it was important to 1) reorganize databases periodically to remove fragmentation that adversely affected performance and 2) back up databases just in case.

In a 24x7 SQL Server 2005 implementation, high level only, how are these and other maintenance related things accomplished with confidence?

I dont think SQL cleanses its own page splits unsolicited. Are DBAs totally reliant on logs in full recovery installations where db must be up 24x7? What if the devices those logs sit on fail? What if the logs become too large? Is it likely that if you want 24x7 you're looking at Enterrise Edition only?

I'm totally aware of and confident in the sliding window partitioning thing but it seems to me there must be more out there in terms of periodic, more frequent maintenance activity.

Variable Memory Utilization And Performance Considerations

Apr 26, 2006

Can someone point me to some good articles or perhaps directly supply some words of wisdom with regard to wise utilization of variables within a T-SQL script from and standpoint of conserving memory usage and improved execution cost?

For example:

(1) Is it better to use varchars, nvarchars, etc. defined with minimal lengths to support the needs of the script or is it just as efficient to declare all with a length of say 4,000?

(2) I've seen behavior that leads me to believe that when passing a variable as a parameter in a nested procedure call, if the declared types of the parameter and the variable being passed in don't match (i.e. one is numeric(38,10) and the other is int), then implicit type conversions hurt performance. Is this true and how broadly does it apply?

(3) Does the number of variables declared in a script materially impact the performance and / or resource utlization?

(4) Is it more efficient to have a series of variable value assignments in a single SELECT statement versus a series of SET statements? Should I always perfer one to the other? Only within a looping construct?

Thanks,

But I have heard a lot of discussion that you can't just simply backup SQL Server data files?
I'm wondering how sound the backup I've created is...

SSIS Task Or Design Considerations For Copying/updating/replicating Tables From One Server To Another

Dec 13, 2007




I need to copy all the data from all the tables in a database to a copy of this database on another server.
What feature of SSIS should I take advantage of to accomplish this?

We have an SLA for 8am, most times the data warehousing jobs complete at 8:05am. Adding an additional process/set of tasks to this package would obviously make matters so I'm trying to update/copy/replicate the data in the fastest manner. Typically we're talking 2 marts (10-20GB) with 2 large tables (5-10 mill records) and 20 marts (0.5 - 5 GB) with many more smaller tables (~40 tables with record count ranging from 1 to a million)

Additionally please indicate if the design/feature you suggest can handle (pushing schema changes and additions to the target server) schema changes or new tablesviews added to the source database.

My only idea so far...is using the import wizard (in Management Studio) to create an SSIS package (top copy all the tables from one server to another) and saving it to the server, Then executing this package after the job is complete. However this would not work if the schema of a table changed, or if a a table is added. Moreover I don't think I can edit this package in visual studio.

Power Pivot :: Structural Data Model Changes In Data Source Leads To Errors

Oct 12, 2015

I've question about how to handle structural datamodel changes in a datasource of PowerPivot. Suppose I'm developing a starmodel in SQL Server and sometimes a datatype changes or a name of a field changes in a table. It seems to me that PowerPivot handle this not gracefully as Analysis MD does (mostly). I received an error because of a wrong fieldname or even no error when a dattype changes in PowerPivot. Is this common or do I something wrong here. Does this mean that every time the datamodel changes the PowerPivot should be recreated? Or am I missing the clue here?

Truncation Of String Data With Data Reader Source Connecting To ODBC DSN

Mar 18, 2007

A data reader is using a connection manager to connect to an ODBC System DSN . A query in the SqlCommand property is provided. Data is being truncated in the only string column . The data type in data reader output-->external columns shows as Unicode string [DT_WSTR] Length 7.

The truncated output in a text file is the first 3 characters from left to right . Changing the column order has no effect.



A linked server was created in SQL Server Management Studio to test the ODBC System DSN using the following:

EXEC sp_addlinkedserver
@server = 'server_name',
@srvproduct = '',
@provider = 'MSDASQL',
@datasrc = 'odbc_dsn_name'

Data returned using "OPENQUERY" does not truncate the string column indicating that the ODBC Driver returns data as expected with sql 2005, but not with the Data Reader.

Any assistance would be appreciated.

Thanks,

Missing Data With SSAS Cube As A Report Data Source

May 9, 2006

I've got a report that is using a cube as a data source and I can't get the report to show all the data. Only data at the lowest level of the cube is displayed. The problem is that most of the data I'm concerned with is at higher levels. There's no problem with the MDX. I get the correct results when I run the query.

I'm using a table to show the results. I've also tried a matrix, but I get the same results. I'm using SSRS 2005 and SSAS 2000.
