3rd Party Performance Tuning Monitor/software?
Dec 21, 2006
Hi all, My boss has asked me to research and recommend a product that our developers (not database developers, but front-end developers that *cringe* get into the database to make the occasional stored procedure) can use to determine the relative efficiency of thier code and/or the database structure and keys.
We currently have a few licensed versions of Quest's Coefficient software, which I think is very usable for such things (I do on a regular basis), but he doesn't think that is "friendly" enough for a GUI developer that is not a database expert.
Any thought and/or suggestions for a 3rd party software package that y'all have used or are using that might fit the bill? I don't mind doing the footwork and research, just thought I would "seek the advice of my peers" to get started.
Yeah, I know the design should drive the database, but we are in various stages of "getting there", so any help in the interim is a good thing.
Thanks for the thoughts and waste of brain cells on my behalf.

If I'm on a remote machine, meaning a computer not in the WSFC cluster, and I open SSMS 2014, point it to a SQL Instance, and open activity monitor:
1. I get all the panes and charts except % Processor Time.
2. Then, if I authenticate to the cluster's domain by mapping a drive with valid domain credentials, I'm free to put performance counters in the Perfmon - - - but SQL Activity Monitor shuts down with“The Activity Monitor is unable to execute queries against server SQL-V01INSTANCE1..Activity monitor for this instance will be placed into a paused state.Use the context menu in the overview pane to resume the activity monitor.
Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))(Mscorlib)”
3. Of course, the Activity monitor can't be resumed via the context menu. Removing counters and closing the perfmon do not work. I dropped the mapped drive and rebooted the machine. That brought back 95% of the information in the Activity monitor.
4. Further experimentation showed that any mapping of drive shares present on the SQL Server to the computer running SSMS cut off functionality of the 'overview' pane in the remote machine's SQL Activity monitor -- the monitor that had been trying to watch the server offering the shares.

Hey all,
I am interested in finding out if anyone out there has experience with extremely high-performance SQL Server applications. The I/O needs of my database server are growing very quickly, and I am on the verge of launching a major upgrade project.
We have done all the standard tuning tasks: proper indexing, stored procedure tuning, etc... and are running on good small-server scale hardware ( dual PIII 700s, 1G RAM, but no RAID). The only path I can see to achieving higher performance are:
- lots of RAID, perhaps on a SAN.
- server upgrade, maybe 4 proc? I've been looking at RAIDZONEs and Netfinity's
- data partitioning ( I REALLY want to avoid this if I can! )
What do you do when you need Major Enterprise scale database performance from SQL Server? I've found lots of resources for Oracle and DB2, but I can't find many case studies for serious SQL Server installations.
Help!
-Dave

Hi,
does the upgradition SQL Server 6.5 to 7.0 will simply solve some problems which we are facing currently like ODBC errors Insert failed and update failed and also supporting more users ?
We have Access front end to SQL Server backend, so do we need to touch code in front end for optimizations ?
Can any pls guide me on this
Thanks

Hi Guys I need someone to assist me in having full understanding of what performance turning is. My Challenge is interpreting the System Monitor Graph of Performance tools.
I needed to know what does the value on vertical axis represent, while there is non on the horizontal axis rather I have Last, Average, Minimum, Maximum and Duration; Please What does all this value stands for, I indeed observe that when I click on any of the counters selected the value changes, therefore kindly assist me so that I can make meaning of this. Apart from all this please assist me with any material that can explain performance tuning to my maximum benefit, thanks in anticipation.
Pls Check below sample of the file is attached

I have a problem that is more complex than the one that follows, but if someone can answer this question,
I believe I can take it from there in solving my real problem.
Why does:
create table #bbb (c int)
set nocount on
declare @a int
select @a = 1
while (@a < 5000)
begin
select @a = @a + 1
insert into #bbb values (@a)
end
run in about 2 seconds, while:
create table bbb (c int)
set nocount on
declare @a int
select @a = 1
while (@a < 5000)
begin
select @a = @a + 1
insert into bbb values (@a)
end
runs in about 20 seconds? (The only difference is that one uses a temp. table.)
What could I have configured incorrectly to cause this behavior?
Thanks in advance!

I have a query which retrieves data from 4-5 tables. To restrict the acess directly to the tables, views have been created on all these tables. These views are just select * from the tables. Two of these 5 tables have 700 Million and 8 Million rows respectively. And all the tables are having indexes. My issue here is that my query on views take three times more then the duration it takes to retrive data directly from tables. e.g. To retrieve 1 Miliion rows, it takes just 7-10 minutes on tables but on views it takes more than 30 minutes. When I check the query plan for both the options, I can see that indexes are being picked up but still the views are very slow.
Creating indexes on views is not feasible option for me as it requires DDL changes and so much testing efforts.

I'm using the Database Engine Tuning Advisor to do some performance evaluation on my database. I have one particular table that will potentially have a couple million rows. but this may not occur for a few months to a year from now.
when i run the advisor with 1.5 million rows, it recommends that i add an index across all columns in this table (covering index) for an estimated 91% improvement. when i run it with 1500 rows in it, it recommends that i add an index on 2 key columns for an 8% improvement.
how should i reconcile this? can i have both and what does that do to performance?

Hi,
I have a stored procedure, I really need some one to help me for performance.
This stored procedure will generate dynamic sql and then paging depending on the @orderbystatement
@orderbystatement could be one column or multiple columns.
Join fields have indexes but execution plan still have hash match on Register table because a lot of duplicate records on
the columns of CalendarAcademicYearId and Worker.
The bottleneck is execution for dynamic sql statement with paging functionality. because all statement after set rowcount 0 only has 10 rows.
This performance task took me a few days and I still didn't get a good idea. Any tip will be appreciated.
Thanks.

I have built a solution which runs for two hours on a server with 4CPU 2GHz each and 2GB of RAM on windows 2000 server (CPU utilization almost 70% and almost out of RAM). I moved the two source databases and the solution to a new box runing 8 xeon's at 3GHz each and 16GB of RAM running widows 2003 server 32bit and it still runs for 2 hours (CPU utilization 10% and ample RAM left).
I was expecting it to run much faster. So I started exploring the performance tuning features in SSIS and started tweaking the following:
Control Flow:
DefaultBufferMaxRows: Based on row size and buffer size, calculated the max rows.
DefaultBufferSize: Set this to max 100MB
DataFlow Destination:
Rows Per Batch: Set this to equal to the numbe of rows expected from the source.
Maximum Insert Commit Size: Set this to zero since memory was not an issue
I took the recommendations from other threads on similar issues here including the excellent recommendations at http://www.microsoft.com/technet/prodtechnol/sql/2005/ssisperf.mspx but now the job is running for 6 hours.
Can anyone explain what I am doing wrong here? I have tried each of the above one by one and all together. No matter what combination I try it does not work any faster and both source and destination database are on the same server. Even selects from the same database also slowed down from 10 minutes to one hour.
Any assistance is appreciated, I need to get this job run in an hour.
Thanks!

I have an SP that is big, huge, 700-800 lines.I am not an expert but I need to figure out every possible way thatI can improve the performance speed of this SP.In the next couple of weeks I will work on preparing SQL statementsthat will create the tables, insert sample record and run the SP.I would hope people will look at my SP and give me any hints on howI can better write the SP.In the meantime, after looking at the SP briefly, my first observations are:1- use SET NOCOUNT ON2- avoid using UNION statements3- use WITH (NOLOCK) with each SELECT statement4- avoid using NESTED Select statements5- use #temp tables6- avoid renaming tables in SELECT statements, for example SELECT * FROMtblClients CAm i correct to consider the above 6 points as valid things in terms ofcausingperformance problems?I would appreciate any comments/helpThank you very much

I have table A and B. A has column ID,A1,A2,A3,A4,A5 columns. B has ID,B1,B2, A1 columns. A table has a trigger. I defined the below trigger.
Solution 1
ALTER TRIGGER [dbo].[Tri_A]
ON [dbo].[A]
for UPDATE
AS
BEGIN
UPDATE B
SET B.A1= i.A1
FROM inserted i
INNER JOIN B
ON B.ID = i.ID
END;
GO
If I change the above solution 1 trigger to solution 2.Can I improve the trigger performance dramatically? I mean only A.A1 is changed then update B.A1. So when the other columns is changed, the update will not be required.
Solution 2
ALTER TRIGGER [dbo].[Tri_A]
ON [dbo].[A]
for UPDATE
AS
BEGIN
IF ( UPDATE (A1) )
UPDATE B
SET B.A1= i.A1
FROM inserted i
INNER JOIN B
ON B.ID = i.ID
END;

Hello friends,
I am in need to tune my stored procedures to get best performance.
First I have a doubt in some SQL statement execution plan,
-- assume "Table_Heat" has one Million records.
-- assume "Mill" column hold value either 1 or 2.
-- assume "HeatNumber" column is Unique.
1. If I have statement like this,
-----SELECT * FROM Table_Heat WHERE HeatNumber = @nHeat AND Mill = @nMill-----
How WHERE clause filter the result from table???
-- In which order the AND statements of WHERE clause will be executed??
2. If I have created Indices for the table Table_Heat
For the above SQL statement -
-- If Index is for HeatNumber --Execution Speed??
