How To Measure Performance?
Mar 6, 2008
I need to create one or two tables in the database. There are a few ways I can design these tables, so I€™d like to measure data loading performance. My primary concern is level of IO generated by SELECT. I don€™t expect CPU utilization to have any meaningful impact, but it would be nice to know how to measure processor utilization as well.
PerformanceMonitor application is not really an option, because it measures IO and CPU at SQL Server process level.
My development box is not going to match production boxes, so I would like to measure IO in terms of amount of data loaded from disks instead of timing stored procedure execution. The same is true for stored procedure CPU utilization.
It is my understanding that SQL Server keeps table content loaded in memory as much as possible to improve performance. How do I negate effect of caching on my IO numbers?

Hello,could you please advice on how to measure replication performancein Oracle, DB2 & MS SQL Server RDBMS installed in Windows servers ?I've got two servers with databases installed and configured,I prepared set of data using DBGEN from TPC and I already imported theminto databases.Also, I configured the replication.Now I have to do a test with a few kind of replications methodimplemented in these RDMBS, but I don't know which tool or reports or"v$iews" should I use to measure replication performance.The replication is configured only between the same RDBMS, I meanOracle <-Oracle, DB2 <-DB2 and MSSQL<-MSSQL.Most of applications are great for checking performance of local DB,not for replicated/distributed.I've found description of CA Unicenter Database Performance Managementfor distributed RDMBS, and I think it could be the right one, but Ican't find any demo or trial version :(Could you please advice any place to download it, or other application,script, description, just whatever.Perhaps just any other idea how to check the replication mechanismefficiency ?Regards,Mark

In my cube there are two measures which are used in different calculations.Now I'm need to show in report if there any months in data when both or even another one of the measures is not updated (value = 0 or NULL).
how should I create the calculated measure for that?
I have tried in mgmt studio to plan this but I'm in a loop of errors.

Hi,
I am wondering how to create a matrix that contains 1 dimension for Top Label (Column), let's say "Year-Month"
and then 2 Measure to be in the row format rather than columnar format.
Example as below :
Year-Month on the column, and the measure is on the row :
2007-04
2007-05
2007-06
Amount Sales
1000
2000
3000
Unit Sales
10
20
30
Total
1010
2020
3030
Please share with me if you have this solution in Reporting services as it works in excel, hyperion brio, bo, cognos but somehow cannot see that function in Reporting Services.
Thanks
best regards,
Tanipar

I want to filter a measure based on another measure (both are measures on the same FACT table).Distinct Number of Users HAVING.User Cost above 0.
I tried doing having but because it’s two measures and not a tuple with a dimension it writes an eror.My query is something like:
SELECT
 [Measures].[Distinct Number of Users ]
having [Measures].[User Cost] >0
 ON
COLUMNS,
[code]....
Â
Please note, that I want it in a MDX query not needing to change the cube or DWH table.

So far we are happy with MS OLAP 2000 service.
In the past we did cubes with aggregation method using summary.
MS OLAP server allows aggregate functions (Sum, Min, Max, Count, and Distinct Count).
But now the customer wants to know percentage of SUM(measure A) /SUM (measure B) in different levels and dimension combination.
Any idea?

Hi,
easy question for advanced users:
I have a dimension called "Movement rate". The members are "1" to "6".
There is a measure called "No. of Products".
What i easily like to do is showing the percentages "No. of Product" for each "Movement rate" of the amount of "No. of Products" without using the frontend-tool.
Thx in advance for any help.

There is count measure in the cube. I need to create a dimension that should list the range of values based on that count values:
Exp:
0-99
100-199
200-399
...
....
..
and so on.
User wants to pick the any range level in the dimension and cube should show corresponding cell values of count measure which would fall into range of the dimension level value.
For example:
if user picks up level 100-199 then cube would filter cell values of measure that has a value between 100 and 199 within 12 month range. So, it would be year to date value of the measure. My problem is how go about creating Dimension that based on measure in the cube and dimension should have level with range of measure values.
Any hint would be appreciated greatly.
Thank You.

Hi,
for a calculated measure I need the total sum of a measure in different dimension. So for example I want to get in my first dimesion 1500 as my sum and in my second dimension too. Is there a way to get it?
(FirstDimension.CurrentMember.Parent, [Measures].myMeasure) doesn´t work!
Best regards,
Thorsten

Hi,
I am newbie in Analysis services. My problem is that I have to show a yearly report for credit expiry. In my fact table the measure is credit rate.
I have attributes of start_day_key and end_day_key. Now when I go through analysis services it does not let me create a measure so that I can count end_day_key for a year (end_day_key is linked to day table with daykey. It has date) and show. The thing is the measure I want is not stored (i.e: the count of end days for a year ). How do I go about it?
Should I create a calculated cell? (I tried that, but mdx does not work)
I used : Count({[Measures].[End Key]})< 366
Now this is not wha I want, I want the end_key count by matching date in day dimension for the current year? Any help is greatly appreciated.

I need to build a cube for membership over time. Active membership is the gap from the record's CreationDate to SuspendedDate, as compared to a reference date (today's active members have CreationDates before today, and SuspendedDates > today, or NULL).
Any idea how to build a cube so I can count membership over a Time dimension? The only approach I've been able to come up with is to create a table with a record for each active member on each date (brute force).

Hello
I am a newbye with Analysis Services and am desperately trying to find a way to include a calculation between one of my measures (Teus), divided by the vessel capacity, where vessel is one of my dimensions (and is therefore not depended on other dimensions...)
Any ideas how I could implement that ?? This would help a lot, thanks for your help,

Hello,
I have a Sales cube and I want to be able to display Products and the
Price at which they were purchased in a given period. I have a
Product dimension while Price is a measure in my Sales Fact Table. Is there a way to have a "Group By" aggregation instead of a Sum? This way, I can show Products grouped by their list price.
My Product Dimension consists of product_numbers (such as 100, 101,
102 etc...)
My Sales Fact Table consists of sales data (such as product_key,
price, net_sales, returns, etc...) at the transaction level.
I want to be able to view the data like this:
Price Net_sales Returns
Product
100 $5.99 $2005 $320
101 $3.51 $7110 $998
where Net_sales and Returns are "summed" and Price is simply a "Group
By". In other words, this report would show the net sales and returns
by product for a given price.
I'd rather not use a Price dimension since we have hundreds of
products at hundreds of different prices. Moreover, this data is
already in the Sales Fact table.
Thanks for any help provided

Hi,
i created a cube that has 2 measures. I created the measures by selecting the columns from my fact table, but the function that applied in the measures was the sum function. I need to apply the count function in my measure. How can i do that?

Hi Experts,
I have a problem:
I have various cube packed in a virtual cube to give me distinctCount Values of customers who purchased products (DC customer] and purchased products (DC product) along with Saleries [RW] over numerous dimensions such as productgroups customergroups etc.
In the calculated measure [RW kum] I can sum the the salaries from the beginning of the year until [time].currentmember with the following MDX-Code:
With member [Measures].[RW kum] As 'Sum(Periodstodate([time].[year]).[Measures].[RW])'
Select {[Measures].[RW],[Measures].[RW kum], [Measures].[DC customer]} on rows,
[Productgroup].[Itemgroup].Allmembers on columns
From [vcub_Sales]
Where [Time].[2005].[march]
IF I use this PeriodsToDate-Formular with the the measure DC customer I will get the sum of distinctcounts of the periods.
What I want is the distinct count of all customers who have purchased since the beginning of the Year until the [Time].currentmember in the same Level.
Given this problem, do I..
1. have make another Cube or
2. another time dimension or
3. is there a way in MDX to get the result?
I would appreciate any replies.

I am hopelessly lost on a MDX-Statement. We are trying to select the last changed value of a measure within the last 30 days and compare this to the current measure value to see wether this has increased, decreased or not changed at all.
We have basically 2 Dimensions (Timeline and Opportunity) and 1 Fact (Revenue). As already described we now want to evaluated, whether revenue has changed within the last 30 days. The result will be displayed in a SSRS-Report (don't have a problem here).
"All" I need to select via MDX, would be the last changed value and the current value. I tried to use the KPI function, but unfortunately to no avail.
How to do such a select in MDX?

G'Day all,
I am having trouble with a calculation that on the surface seems to be working until it is opened up in excel.
The measure calculates the Actual Value as of last year and is as follows - ([Measures].[Act Val],ParallelPeriod([Time].[Year],1))
This works fine until I look at the totals within EXCEL 2002/2003
1)If I choose to view a whole year then the total shows me a whole year. That is fine and as expected.
2)If I choose part of the year the total shows me the whole year. This is wrong and am wondering if it is an Excel probem or my calculation? But here is the weird part -
3)If I choose another year and select the same months as I have already chosen (ie Year 20023 Jan, Feb and Year 2003 Jan and Feb) then the total for the year that is already selected works!!(shows only the total of the two months - whereas the extra year I have selected (remember - Jan Feb only) shows me a total for the whole year.
WAIT - There's more
4)If I add another month to the 2002 selection (ie add March) then the total for 2003 (Jan Feb only) includes the March value also (even though it is not selected)!!!!!!
Any Ideas??
Does it make sense??
Thanks
Matt

I'm trying to create a percentile rank function based on the standard WIKI version:
I've seen Brian Knight's article here, but that only deals with percentile.
Where I'm struggling is getting the count of members in a set using a measure, in the current context on the same hierarchy, as the filter expression. I'm using the comparative set as in belonging to the same geographical location, and therefore associating by another attribute.
So, cl as below:
MEMBER [Measures].[RegionPercentileCount] AS
Count(
Filter(
NonEmpty(
descendants(Ancestor(
[Supplier].[NameMap].CurrentMember,
[Supplier].[NameMap].[Region]),
[Supplier].[NameMap].[Supplier Id]),
[Measures].[ActiveMeasure])
, [Measures].[ActiveMeasure] <
([Supplier].[NameMap].CurrentMember,
[Measures].[ActiveMeasure])))
Using the same measure and context hierarchy is always going to be equal, and therefore the count is always zero. Its almost as if I need a nested context for the FILTER which allows me to use enumerate the set on the same hierarchy whilst maintaining the external reference.Â
I'm thinking that perhaps I'm going to have to create another hierarchy and use that as the filter set and reference through StrToMember or similar.

Hi, there,
I have a semi-additive measure in the report. This measure is additive across product groups (row) but not across the period (column). The period (column) can be drilled up to 1st Half (from Jan to June) and 2nd Half (from July to Dec).
How do I make the subtotal for 1st Half to retrieve from mth June and 2nd Half to retrieve from mth Dec?
Thank you.
Regards,
Yong Hwee
