Hi,
Is there any SQL Server functionstored procedure available to get drivesvolumes and mount points total size and free space information?
I don’t want to use clr approach for this.
Can you please provide any pointers related to this.
Thanks in advance,

Can any one advice or give me tips over this. Please
We have an application that was built and testing using SQL Server Express. One of our clients is deploying it using SQL Server Standard and plans to put the data files and log files on separate disk volumes.
In allocating the available disks to the volumes, they are looking for a recommendation on how big the log file volume versus the data file volume should be. Over time there will several years worth of data in the data files. I assume the log files need to be at least big enough to log all the changes between back-ups. Are there any general rules of thumb? Or whitepapers that discuss the trade-offs?
Thanks in advance...
Hi,
I am getting this error when I try to run a script to create a table. The error reads as below
The total row size (12488) for table exceeds the maximum number of bytes per row (8060). Rows that exceed the maximum number of bytes will not be added.
Can somebody tell me what I have done wrong?
thanks

We can find free space on disks with 'xp_fixeddrives'.
I need script to find all disk size(total sizecapacity) in the servers?
I have a table that writes daily sales each night but it adds the day's sales to the cumulative total for the month. I need to pull the difference of todays cumulative total less yesterdays. So when my total for today is 30,000 and yesterday's is 28,800, my sales for today would be 1,200. I want to write this to a new field but I just can't seen to get the net sales for the day. Here is some sample data. For daily sales for 6-24 I want to see 2,000, for 6-25 3,000, 6-26 3,500, and 6-27 3,500. I'm thinking a case when but can't seem to get it right.
CREATE TABLE sales
(date_created date,
sales decimal (19,2))
INSERT INTO sales (date_created, sales)
VALUES ('6-23-15', '20000.00'),
('6-24-15', '22000.00'),
('6-25-15', '25000.00'),
('6-26-15', '28500.00'),
('6-27-15', '32000.00')
I am looking to improve the performance of my sql server databases.
I currently have a dual location system, the database server setup is basically a quad xeon with 4gb at my office and a double xeon with 4gb at a remote webhosting location. There are separate application/web/intranet servers at each site. The two databases servers are replicated with the local server publishing to the remote server.
The relational database holds circa 26 million records, growing by a volume of 10,000 per day, there are approximately 50,000 queries performed per day.
My theory is that the replication of the two databases is causing a slowdown; despite fast network connections (averaging 200ms between servers) the replication seems to place a large load on the local server. Would it be sensible to replicate to a second local server and then replicate to the remote server, placing any burden on the second server?
I am planning to upgrade the local server to a high capacity 4+ cpu 64bit server, my problem is that although I have noticed a slow down in performance over time, I am unsure how to go about measuring and quantifying this in order to diagnose the bottlenecks and ensure that investing in a new server would be worthwhile. Where would one be best advised to start this project?
We are in the process of moving existing clustered SQL server databases to AWS. There is one major database that has intensive reads and writes transactions. I'm wondering what is the best design to optimize the performance for both R/W since we have constant issues historically with the current environment when massive updates are happening. Reads shall have higher priority over writes.

I am copying data from database to an excel file through SSIS. database is MS SQL 2005 and BIDS is also 2005.However, the job doing this task fails every time.As per investigation, the result of the query is more than 100,000 rows and we know that excel has a limit of 65000 rows of data.Is there a way of setting the limit up? or something? a better approach maybe so that everything will be copied to the excel file successfully.

Hi, can anyone help?
I have created a Report using Visual studio-the report displays a subreport within it.
On the Subjective Report I have 12 values for each month of the year.
For the first month the value is =sum(Fields! Month_1.Value), and I
have named this text box €™SubRepM1€™
The name of the subreport is €˜subreport1'.
On my Main Report, again I have 12 values for each month of the year.
For the first month the value is =sum(Fields! Month_1.Value)*-1, and I
have named this text box 'MainRepM1'
The name of the main report is 'GMSHA Budget Adjustment Differentials'
The report displays both of the subreport and main report values
but I now need to total these values together for each month in order to
produce a grand total.
I have tried using the following to add the totals for Month 1 together,
=subreport1.Report.SubRepM1 + MainRepM1
but this does not work and I get the following error message €˜The value expression for the text box 'textbox18'contains an error [BC30451] Name subreport1 is not declared'.
I feel that it should be a simple matter of adding the two sets of values together but I€™m having major problems trying to get these totals to work.
Can anyone help, thanks
We have a 4 processor 350 Hz NT 4.0 SQL server. Currently we have an application
that is inserting rows one at a time, each row insert is a separate transaction.
Currenty we are averaging 2500 rows a second with each row ( 56 bytes wide).
The data and the log are on one string of Raid disk. We plan to get another controller
and raid string to separate the data and the log onto separate controllers.
The developer is modifying the application to insert the data in blocks. What is the
impact to the transaction log? He seems to think that by inserting page blocks on
rows there would be less data going into the transaction log. Why would this be so?
Does anyone have any information on practical limits for inserts and log truncation
with similar machine configurations. He would like to try to get around 150,000 rows a second.
Has anyone accomplished inserts at this rate? What type of machine configuration?
I have a summary table with a 9 field composite primary key. Every 10 minutes, my system generates 2 files of 500,000 to 750,000 rows to be summarized into this table. I first Bulk insert those into a temp table, and then trigger an inner-join update query to do the updates, followed by a left-outer join to do the inserts. As the day goes on, millions of rows in my summary table, this process is too slow. Any ideas about causes/solutions???

Hi Guys
I Have not been able to solve this problem from quiete a while now.
I am using sql server 2005.
I have got a table which contains these columns - start date, end date and volumes
if the month in the start date is same as that of end date, the volume remains same, else if the months in the two dates are different, then i have to distribute the volume in such a way that some part will go in the first month and the rest in the other month.. i have to somehow calculate (or prorate) the volume according to the no of days in each month
I have to perform a query on this table so that I can group the volumes for different months and different years.
Hope I have made this quite clear.
Thanks

Hi Guys,
I am facing problems with concurrent access in SQL Server 2000,The scenario is that the DB contains one huge de-normalized table containing 40 million records.
The application frequently queries this table to populate other derived tables,the sql queries take a long time to return results.
So if one query is in execution the other user's query goes into a
wait mode.Please suggest how I can better this.
Or do I need to upgrade to 2005.

Hello ,i am a master student and i am making a seminar about high volume DB performance problems ,example : if i have a table with length of 1000000 record and this length is growing exponentially by the time,what the problems may i face in insertion ,deletion , search,in such table?? and what the problems in processing such DB in general
View 1 Replies View RelatedHi Good morning to all,
My day started with loading huge volume of data and my data flow task failed to do so.
My data flow has a flat file connected to a OLEDB target. This is a one to one mapping. My source file contains 50 lac records and it is of 500 MB in size.
I'm processing the data with all the default buffer settings. I have 4 CPUs in my server.
the system process DTSDebug.exe is utilizing more than 2GB page size. My average CPU usage being 70% when one of those CPU s is hitting 100% utilization.
I'm very new to SSIS. So, please provide me some info how do i set my buffers and do we have any PDF for performance and tuning in SSIS ?
Do we have any bulk load transformation in SSIS to load into DB2UDB ?
If so how do i get it installed?
Thanks in advance,

I am in the process of choosing between either SQL Workgroup or Standard Edition. I see the differences in features on the comparison table, but do not see any references to the differing capabilities in handling transactions.
Is there any differences between Workgroup and Standard in terms of handling transaction/data capabilities? i.e. Does Standard have the superior capability in handling X times more TPMs than Workgroup?
If not, am I correct to assume that this is totally determined by hardware configuration (# of CPUs, processor speed, HD speed, RAM) ?
If the data volume / transactions handling is solely determined by hardware configuration, and I know the # of transactions and amount of R/W per second, .......where would be a good reference to know what kind of hardware configuration I need (ideally, once I know the hardware configuration, I guess I would be able to determine I need Workgroup or Standard)
Thanks in advance,

We are creating an enterprise application for fuel, and I am fighting with my DBA about the proper way to store volume and currency in the database. We have 2 main arguments. The first argument is whether we should store costs in the database in $ and convert in the presentation layer, or to store the amount and currency in the database. We sell product from the US in dollar but depending on the customer we may invoice in Euro. Our second argument is the same, execept with volume and UOM. We often purchase product by BBL but sell/transfer by gallon, or Ton.
please tell us the best practice for our dilemma.
Not really a question. Just looking for people with experience with SB in a highly transaction env. with passing a lot of messages. What kind of challenges have you ran into when you are processing the messages. I am currently writing a SB application for a large financial institution, and want to get some ideas of challenges that I might face when volume gets really high (couple of million transactions per day).
Thanks,

Hi,We need to use a free database for a project because of tight budget.Is MSDE ok for handling large volume of data and 70 - 80 users?My understanding is that MSDE is optimized for 5 concurrent users.Is MySQL better than MSDE?Thanks,Ben
