Clustering, Security, Performance, Load Balance
Nov 27, 2007
I think this question has been asked number of times. However, I am
looking for some specific information. Perhaps some of you can help
close the gap. Or perhaps you can point me towards right direction.
Perhaps this group can help me fill in ms-sqlserver related following
questions.
1. Do this database have data Clustering capabilities?
1a. If yes, what mechanism is used such as shared disk, share nothing,
etc.
2. Do these dB have Security features?
2a. If yes, what security features are supported? For instance do they
support encryption or SSL connection?
3. How does the database perform and what is the criteria for the
performance matrix?
4. Do they have inbuilt load balance capabilities?
I want to thank everyone for taking your time to read this
correspondence. I will also greatly appreciate your efforts in sharing
your thoughts.
Regards,
Manish

For our application we are planning 4 Appserver/webservers with load balancing and 4 SQL servers in cluster with active/active setup. We are looking for some info on the active/active setup for SQL server 2000 Clustering.
1. Which cluster node replication method (2n, 2n +p or n+1) we should go for.
2. How operating system "windows 2003 server" should be configured and its role in failover.
3. How active/active failover setup for SQL Server 2000 really works and how much data loss happens in case of failover.
4. For web applications, how the session state is managed in SQL Clustering

Currently we have a single SQL server. It went down and the higher ups were none to happy. Lots of money lost, down time, unhappy customers....the whole nine yards. They want to throw all sorts of money at the problem and want a solution that is high availability and provides load balancing. I think I came up with a solution.
3x Windows 2003 Enterprise Edition servers running SQL 2005 Standard in a cluster all connected to a SAN.
I'm guessing I need to set up Network Load Balancing in order to load balance the SQL database. What we would love to have happen is if one of the servers goes down, everything else just picks up. That coupled with our database that is increasing in size and transactions gets load balanced.
Am I going down the right path? Something else I should look at? Or that I am missing?
Thanks!

I have a table with Million plus records. I have been able to calculate the Trial_Balance for all months.
Now I am trying to provide a Beginning Balance for all months and the Logic is the Beginning Balance of July would be the Trial_Balance of June. I thought I could just do a self Join but this is not working.
UPDATE dbo.TrialBalance
SET Beginning_Balance_Debit = B.Trial_Balance_Debit
FROM (SELECT DATEADD(month, -1, Calendar_Month) AS PrevCalMonth,Trial_Balance_Debit
FROM dbo.TrialBalance) AS B INNER JOIN dbo.TrialBalance A
ON b.PrevCalMonth=A.Calendar_Month
[Code] ....

When a web application becomes overloaded with traffic, one can offload itby load balancing and clustering the front end web servers. What happenswhen the back-end MSSQL database becomes overloaded? Does MYSQL offer loadbalancing and clustering?

Hello.
I am confuse and cant decide on how to setup high availability on our SQL 2005. Here's what on my mind and on resources list:
I plan to have mirroring on my SQL1 to SQL2 with the help of SQL3 as witness. So this would be automatic failover. My idea on mirroring is when SQL1 goes down, SQL3 would tell SQL2 to run and be the primary. It will automatically failover to SQL2. Right? My questions are:
1) How can I revert back to SQL1 once it is ready?
2) I read in one of the post that it is impossible to write in a mirrored DB, is this true? I mean, what's the use of failing over to the next node when it's not possible to write and update data/records?
3) If number 2 is false (i hope so), how would the data be synchronize from SQL2 back to SQL1. Those transaction that were made while SQL1 is down.
4) How about the connection string from the web applications? Would it be automatically point to SQL2? We have load balancing setup in place, would this help web application connection to automatically point to SQL2?
Another setup:
We have SAN in place (not yet used, but is planning to use for this SQL thing), EMC to be specific. My question would be:
1) For SAN setup, the data storage would be centralize. So would that mean that SQL1 and SQL2 services will use the same data and log file from the SAN storage?
2) How would you call this setup then? Can this be clustering type of high availability? Will clustering work under load balancing setup? I believe mirroring is not possible here? Right?
3) How can I setup my 3 SQL servers with the same theory in mind: when SQL1 goes down, SQL2 will take over. Data will be synchronize when SQL1 is up and running again. With automatic failover and reverting back to primary.
I read so much topics about this, but the more I research, the more I get confuse.
Any suggestions, comments, advice is greatly appreciated!

We are using a VB application with a "dsnless" connection. It is not able to connect to the SQL box using integrated WinNT authentication. Receive the below error message:
Run-time error '-2147217843 (80040e4d)':
[Microsoft][ODBC SQL Server Driver][SQL Server] Login Failed
We can connect to our test SQL box with using the same application with no problem. The only difference we can see is the clustering on the "real" box.
We are using the following program string to connect to both boxes with the exception of the server we connect to:
"driver={SQL Server};server=server;uid=;pwd=;database=pubs"
Any info. would be greatly appreciated!
Thanks :)

Hi all,
We have 2 database servers with same configuration.
One is Development server and the other is Production server. The Production database server is clustered.
We find the same queries taking more time in the Production server which is a clustered server.
Will the clustering affect the performance in any way.
Any help would be appreciated.
Thanks,

Hi,
I'm a businessperson, not a software engineer, so please bear with me if my questions seem simple.
We are about to migrate from MS SQL Server 2000 to 2005. In our 2000 deployment, we have a primary server, with real-time replication to a backup. If we have a hardware failure, we do a manual failover to the backup server. This has served us well for years, with decent performance and no data loss. The SQL server is accessed by a pair of IIS servers, which use network load balancing to split the load between them.
As part of the forthcoming migration to SQL 2005, we are going to a hardware platform with 2 SQL servers sharing a single storage array. We would like to get the performance benefit of utilizing both of the SQL servers to handle requests simultaneously, and not just have the second server as a backup. Ideally, the two IIS servers would dish requests to both SQL servers, either randomly or in some sort of load-balanced manner.
So here is my question: how can we have both SQL servers active and handling requests simultaneously, achieving both high perfromance and high uptime?
If it is not supported natively in SQL Server 2005, is there a third-party software solution that can achieve this?
Finally, where else should I go to do further research on this subject?
Thanks in advance for any help you can offer.

I'm trying to improve the loading of some tables with large amounts of data that forms part of an ETL. I was going to try removing any indexes before the inserting to speed up the process, but I had some questions on whether or not I should include the clustered index (assuming one exists).
I was originally planning on including a step to disable all indexes on the destination table using the following:
ALTER INDEX ALL ON MyTable DISABLE
Once the load had finished I'd simply rebuild all the indexes.
should I simply disable the non-clustered indexes?

Hello!! guys..
I am using sql server 2005 enterprise edition in the clustered environment with netapp storage (one server) I monitor the server performance, basically using windows performance monitor counters such as avg.disk queue length,avg. disk reads/sec, avg disk writes/sec, processor time, available memory Mbytes, cache hit ratio etc. and using some sql server dmvs .
At this point all looks good.
My problem i dont know how much load sql server can handle more .How much it being utilized now? whehet it has reached its limits...how do i know it is just about to reach its linits??
how much throughput sql server is handling at present, how much more it can handle if incoming traffic increases.
Basically i want to find performance baselines , how much more it can handle so that i can plan for the future ..
How do i measure all this?
what are different methods available if i want to handle increased incoming traffic? (e.g. adding multiple servers etc.)
It will be really great if someone can share his experience on this..
Is there any article/white paper on this ..
Any suggestion/help appreciated
Thanks

Need help, I am managing a Data Warehouse (80 G.B Database Size), I purge older than 6 months data from a table which has more than 140 Million rows on daily basis. The daily data load performance is degrading. The table has no clustered indexes (only non-clustered indexes).
Tried dropping and rebuilding the non-clustered indexes, didn't work.
One way to solve the problem is drop the non-clustered index, bcp out the data, truncate the table and bcp in the data and rebuild the non-clustered indexes. This is too risky and taking 14 hours to bcp out the data.
This was not the issue in SQL Server 6.5, because SQL 6.5 always insert new record indexes at the end of the heap link (heap = non-clustered indexes without clustered index). In contrast, SQL Server 7.0 first checks for available space in existing pages by using percent free space pages (this is where it is killing the performance ).
Thanks for your help!

Hello to all the members.
I have a SQl server on a Win2000 box. The server is located behind a screened subnet, and has no access to the outside world except for 1433 and 445 inbound from a webserver located in a DMZ, forward of the internal firewall. Rules are very tight, and the IIS box is patched and has been hardened further including running urlscan. (allowed verbs=get,head,post. all executable and script types disallowed, permissions very tight) I have written an appication that monitors bad http requests in real time to check that the URL scan is working, and it seems to be. The only way to get to the SQL box, would be running injection on page code (majority written by myself no raw sql) on the web server or launching an exploit over HTTP against known ADODB flaws on the web server. The SQL server is a domain member, the IIS server is a standalone. If theres a way to compromise the SQL box without first breaching both firewalls, or first compromising the IIS server, I dont know how to do it. Still, the sql box began acting up, refusing to accept a terminal services connection (the error stated that there was a failure to load Win32.sys) No sign that the machine had been compromised. I restored from a complete back up, which seemed to fix the terminal services problem, but now the sql performance counters fail to load. Specifically MQPERF.dll. Any ideas on what may have caused the server to have 'issues' (prevailing theory centers around evil spirits), and what can I do to get the performance counters to load. Tried replacing the library.
Thanks in advance,
VLG

Hi,
I've created a custom dll using ADOMD.net that takes in a few parameters (Username being one of them) and returns a set of Allowed Members to apply dynamic dimension security. Example:
Code Snippet
Security.GetSetList(UserName,1,"SQL Server")
This works fine for users with less than, say, 100 tuples/members in their set....however for users with more an error:
Error ocurred retreiving child nodes: The 'S' attribute in the 'S' dimension has a generated dimension security expression that is not valid. ...
However, if I take the same set and explicitly (ie
Code Snippet
{[S].[1],[S].[2],.......[S].[50000]}) put it in the Allowed set there's no issue!
I noticed that it takes the UDF a couple of seconds longer to return for users with a large security context. Is there a time-out parameter that controls this? Is there a limitation in the amount of members I can add via custom dll (UDF)? (Some users can have up to 70,000 members)
I should also mention that the UDF uses the StrtoSet function to convert the security context string to a set. The string can be as large as 210,000 characters. Is there a limitation on the string size that can be passed in this function?
Any assistance would be greatly appreciated.
Thanks!!

We have 2 env. : Testing and Production, both are running Windows 2003 Enterprise Server with SQL Server 2005. The difference is Testing is NOT running Windows cluster but Production do so, what is the best way to transfer a database from testing to production?
We have another systems that both testing and production are running on NON-cluster and we use backup/restore to transfer the database, can it apply in this case.
And I found that there are a tools called DTC, which can transfer all DB objects from one DB to another, is it a best way to transfer between non-cluster and cluster env.?

Hello,
I started to use data mining sql server recently, and I have a little problem:
I'm trying to predict a boolean variable, but my database has only 1/4 of true results, because of that my predict probability is a little bit low in this kind of cases.
My question is: Is there a way of increasing the importance of a database entry in order to avoid editing a database with 40000 entries?
Thank you very much.

This is what acutally I am having in my stored procedure except the temporary table. The values which I am inserting here will get from my actual tables. What I need is to calculate balance. If you run this script you can see how the balance is calculating using the cursor.
I want an efficient way to calculate the same. I know cursor is not at all good option in stored procedures. Do you have any Idea to make this script in an efficient and simple way?

Hi guys, I've really been struggling with this issue for quite a while and the solution still elludes me.
If anyone can help me I will worship you as a god for ever! [Wink]
The Scenario is as follows:
I have a table where several documents are linked to each other via a foreign key called ReconNum.
Basically this table is used to link Invoices, Credit Notes and Payments to each other.
Thus you get the following layout:
ReconNum LineID DocID DocType ReconAmount
111 0 101 Payment 20 000
111 1 202 Credit Note 12 0000
111 2 303 Payment 5500
111 3 404 Invoice 10 000
111 4 505 Credit Note 22500
111 5 606 Invoice 30 000
111 6 607 Invoice 20 000
What I need to do is assign values from each of the Payment/Credit Note documents to the Invoices. Thus getting the following result:
Inv# DocID DocType AmountApplied DocBal InvBal
404 101 Payment 10 000 10 000 0
606 101 Payment 10 000 0 20 000
606 202 Credit Note 12 000 0 8 000
606 303 Payment 5500 0 2 500
606 505 Credit Note 2500 20 000 0
607 505 Credit Note 20 000 0 0
I've come close, but it seems to be the old chicken or the egg problem.i.e. I need one field to calculate the other and vica-versa.
(Amount Applied, DocBal and Inv Bal are all dependant on each other)
NOTE: The only field I'm really interested in is the AmountApplied field, but amount applied depends on the DocBal and InvBal fields.
I need a running balance on both the Amount Due on the Invoice, and the Amount Availble on the document being assigned to the invoices. The problem is that I'm trhowing the data into a temporary table and cant use fields in the temp table for my calculation.
i.e. AppliedSum = if (Doc.Available amount on Doc < Invoice Balance) then Doc.Available Amount
elseif (Doc.Available amount on Doc > Invoice Balance) then Invoice Balance
Invoice Balance = Invoice Tot - sum(Applied Amounts)
Any help would be breatly appreciated!

helo all...,i have create procedure can decrease totalcost from order table(database:games.dbo) with balance in bill table(database:bank.dbo). my 2 database in same server is name "boy"
i have 2 database like: bank.dbo and games.dbo
in games.dbo, have a table name is order(user_id,no_order,date,totalcost)
in bank.dbo, have a table name like is bill(no_bill,balance)
this is a list of bill table
no_bill balance
111222 200$
222444 10$
this is a list of order table
user_id no_order date totalcost
a 1 1/1/07 50$
when customer insert no_bill(111222) in page and click a button, then bill table became
no_bill balance
111222 150$

I am working on a software primarily related to accounting with visual basic
Many of the problems and proposed several solutions for running sum, but I have read almost all of these interpretations,
have applied when running sum is a unique ID field. but almost all of the functioning of accounting reports are in chronological order. So he questioned what was the balance on 05.05.2012.
ID of the process is done, if the user enters a process backward a few things since then, the transaction date is old, but the ID is new, are experiencing problems. eg
ID DATE DEBIT CREDIT BALANCE
1 02.02.2012 100.00 0.00 100.00
6 04.04.2012 0.00 150.00 -50.00
3 02.05.2012 70.00 0.00 20.00
4 02.05.2012 80.00 0.00 100.00
2 06.06.2012 120.00 0.00 220.00
must balance the figure above.
if ID = 2 record, the record date 06/06/2012 and if the ID = 6, date 04/04/2012, the date the order is made if the listing is experiencing trouble getting balance. 2 records in the same day when the balance at worst formula breaks down. The big point is that I hang out in my project.
the only solution is to use a temporary table or writing about it in Visual Basic seems to calculate. the use of temporary table is not a solution, but unfortunately also very fast.

I am struggling with the Lastdate function. I have got stock balance data and want to show the number of products/models that are on stock at the latest date of the stock balance table.
My DAX formula is as follows:
=CALCULATE(DISTINCTCOUNT('3S-StockData'[Article Model]);LASTDATE('3S-StockData'[Date]))
I get the wanted results for all aggregated product groups, on product/model level however the formula does not give me the information wanted (see screenshot).
Basically, the formula calculates correct, but I want in my example only models shown with the date 2015-10-21.

I have query that calculate a running balance, but I need to reset that balance when it reaches 240. Then start calculating the balance again from that value. For instance, let's see we have the following table:
YearAmmount
200049.95
200179.92
200279.92
2003114.99
2004120.00
[Code] ....
If I run the following query to get the running balance:
SELECT Year,
Ammount,
SUM(Ammount) OVER(ORDER BY Year ROWS UNBOUNDED PRECEDING) AS RunningTotal
FROM _YearlyTotals
I get:
YearAmmountRunningTotal
200049.9549.95
200179.92129.87
200279.92209.79
2003114.99324.78
2004120.00444.78
[Code] ....
I'm looking to reset the Running Total if it reaches 240, and continue calculating from there: Something like this:
YearAmmountRunningTotalAdjustment
200049.9549.9549.95
200179.92129.870.00
200279.92209.790.00
2003114.99240.00-84.78
2004120.00240.00-120.00
[Code] ....
Here is the code to create the table and insert data:
CREATE TABLE _YearlyTotals(
[Year] int NULL,
Amount numeric(18, 2) NULL
) ON [PRIMARY]
INSERT INTO _YearlyTotals([Year],Ammount) VALUES (2000,49.95)
INSERT INTO _YearlyTotals([Year],Ammount) VALUES (2001,79.92)
[Code] .....

I am preparing a monthly cash flow statement and for doing so, I need to determine the monthly opening and closing cash balance. To simplify, this is what I did.
1. Dragged months to the columns labels
2. Created a slicer for selecting the Financial Year. In this slicer, I chose 2015-16 i.e. April 1, 2015 to March 31, 2016.
Since I have data only for two months of this Financial Year i.e. April and May, only these two months show up in the column labels.
To determine the monthly opening cash balance, I added the following measure
=CLOSINGBALANCEMONTH(SUM(bank_book[Balance]),PREVIOUSMONTH(calendar[Date]))
To determine the monthly closing cash balance, I added the following measure
=CLOSINGBALANCEMONTH(SUM(bank_book[Balance]),calendar[Date])
Much to my surprise, I got the result as seen in the image below. Cells B5, C6 and D5 are blank. On going through my Bank Book, I realised that
1. There is no figure in cell B5 (Opening balance of April) because there was no transaction on the last day of March i.e. March 31. The last transaction was on March 28
2. There is no figure in cell C6 (Closing balance of May) because there was no transaction on the last day of May i.e. May 31. The last transaction was on May 30
3. There is no figure in cell D5 (Opening balance of June) - same reason as mentioned in point 2 above.
As seen in the image, I have also computed the monthly "Last date of previous month" and "last date of current month" but do not know how to make use of them in computing the opening and closing Cash balances.
Please also note that there can be multiple transactions on the last day of any month. For e.g., let's say the last day of transaction in May 2015 was May 30 (not may 31) but there were multiple transactions on this last day (both inflow and outflow).
So I cannot simply determine the last day of transaction and take MAX/MIN/SUM that day. I have to take the final balance on that day.
How to solve this problem i.e. in determining the opening and closing cash balances.
