Statistics Help

If anyone can clarify this for me it would be greatly appreciated.
Can statistics collection be classified in 2 groups, Optimizer and Performance (AWR) Tuning? I ask this because I am reading Oracle 10g Admin Workshop I, chapter 12 "Proactive Monitoring" and does not make a clear distinction between the above areas. Since STATISTICS_LEVEL seems to apply to both and the location of the stats collected differ (dictionary for optimizer and WRx$ for AWR) I just want to be sure I am comprehending correctly.
Matt

Matt,
The term Statistics got the same meaning everywhere,information required to do some analysis. This means its true in the case of optimizer also as well as ADDM also.Now as in the link given by you, this lines clearly mentions that ADDM uses the AWR data.
ADDM examines and analyzes data captured in the Automatic Workload Repository (AWR) to determine possible performance problems in Oracle Database.
So AWR forms the basis of the data that is used by ADDM.
Now if we look at the AWR definition and see what does it contain, the term is same ,Statistics but see for how many areas it is collected,
http://download.oracle.com/docs/cd/B19306_01/server.102/b28051/tdppt_method.htm#CAEICJEI
The database statistics collected and processed by AWR include:
Time Model Statistics
Wait Event Statistics
Session and System Statistics
Active Session History Statistics
High-Load SQL Statistics
So I am sure now the idea of statistics should be clear.Where ever it would come, it has one meaning only that it refers to information which is meant for analysis purpose.Optimizer uses that information in its own way , ADDM in its own and so on.

Friends -
I have activated all 0TCT content for new BI statistics. I find that with this new content it is very difficult to find some information that was very easily accesible with 3.5 content.
For example, I would like to see query and cube usage information. In 3.5 their were standard queries to see how frequently a cube or any object was used. In addition there was a standard query to determine when a query was last used.
Should I be using the 0BWTCT content in conjunction with 0TCT. I though 0TCT replaced old content - now I am wondering if I am supposed to use both.
Thanks in advance for any help.

Friends -
I have developed a method for determining cube usage. It is not a simple as with the 3.5 stats.
I am using the data manager statistics. I have modified BC Query - 0TCT_MC03_Q02. I chose to look at the data manager stats so that I could get cube usage. I.E. if a query is run against a multiprovider, I wanted to see the underlying cube usage. In many cases when a query is executed against a multiprovider only a subset of the cubes in that MP are used. That is the granularity that I captured my interest.
In the rows column of the query I included:
PartProvider 0TCTPARPROV (This gives the basic cube used)
InfoProvider 0TCTIFPROV (This gives the multiprovider name that was used)
Query Step 0TCTSTEPUID (This provides the query that was executed - you have to include this level of granularity to obtain a count of how many queries were executed, because there is not a key figure that represents the number of executions)
In the rows area I inlcuded:
Rec., trans. from DB 0TCTNDBTRA (Records transferred from the DB. I chose this because in many cases in a poorly written query against the multiprovider, the query may actually select from a cube but not return any records - because multiprovider pruning etc. has not been applied. I chose to determine an execution against a cube as any query that returned records from the selection)
Count # Records trans. > 0 (Here I just simply included a count variable to count 1 for every record where the records tranferred was > 0)
With the above query I was able to determine the number of query executions that returned records from the DB for each cube and the related multiprovider if one exists. What you don't get from this query is cubes that were never used. So, I took the list from above and combined it with a list of all existing cubes to get the clear picture of used an unused.
This is not a great solution, it required manual effort and is probably not 100% accurate. It seems to be such a basic question - I am not sure why SAP decided to remove the valuable query that was provided with earlier statistics.
Hope this helps. If anyone comes up with a more elegant solution, I would love to hear about it....
Cheers-

Update statistics for database

I'm needing to update stats on all tables in the database, and an unsure how to do so, and haven't been able to find any documentation for it. Could someone help me in this, show me the code on how to make this happen.
Thanks

Hi,
There are multiple sites and articles that explain the issue in depth (just google oracle statistics, [http://www.oracle.com/technology/pub/articles/lewis_cbo.html] is a very good example).
Basically statistics help generate execution plans for your queries and DMLs.
It is recommended to gather statistics with the DBMS_STATS package ([http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_stats.htm]).

Yuri

SUN IDM8 Performance question

I have deployed IDM8 on Sun Application Server 9.1 on RHEL 4.6 with Oracle 10gr2. All are on the same machine. I have given 1 GB each initial/max heap sizes. The performance seems to be horrible for a single user (e.g. configurator) just logging to IDM initial page -- 3-4 minutes. After then same thing for every item. This is a fresh install and almost no load is there. I see the machine has lots of free memory, no paging and CPU utilization is not more than 20%. Looked at garbage collection and that was going pretty fast. What may be the reason & how to fix it? Thanks.

One thing to keep in mind with Oracle is that immediately after a fresh install and new data population the indexes and statistics are out of sync with the data in the database. Those statistics help Oracle decide how to retrieve the data from the database. If the statistics are old then sometimes Oracle will make the wrong decision, for example chosing a full table scan over an index based look up.
Oracle will eventually rebuild those statistics (usually it's a job scheduled to run nightly but it depends on your config) but it might be worth asking your DBA to force them to be rebuilt.
Having said that, I'm personally not terribly impressed with the performance of either IDM 8.0 or IDM 7.1. The IDM application itself does not take advantage of multiple CPU cores so running it on a platform such as Sun's T1000/T2000 series servers does not help. It's far better to use a system with very fast CPUs but limited execution cores over a system with a ton of cores and slower CPUs. There's very little multi threading done within a single user's session.
On the back-end database side, IDM defines the schema to use and I think there could be some improvements there too. It took me a solid week of database tuning (along with using Oracle's query rewrite feature) just to get the performance up to an acceptable level.
One example I have is if you have a large number of users in a single organization (over 100k) and, as an admin, you try to expand that organization and page through the user list the system slows to a crawl. Each click to move to the next "page" of users takes minutes and since IDM remembers were you were in the account listing every time you return to the account tab there's a several minute delay. Since it's only on the admin side of things we're going to live with it. There's no way that type of a performance problem is solely related to the back-end database.
Anyway, I'll stop ranting. Rebuild your Oracle statistics and indexes. Something like "EXEC DBMS_STATS.gather_database_stats;" as the sys user will help but really you should talk to your DBA.
If you're not using a lot of CPU it likely means you're hitting the disk a ton. The second thing you might try doing in cranking up your JVM heap size or changing your garbage collection method. Here's what I use (I'll leave it up to you to look up the meaning of each of the command line options) for the jvm:
-server -XX:+DisableExplicitGC -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -Xms1024m -Xmx1024m -XX:SurvivorRatio=128 -XX:NewSize=300m -XX:MaxNewSize=300m -XX:MaxTenuringThreshold=0 -XX:CMSInitiatingOccupancyFraction=60

High Pings, slow performance. Good line stats. P...

Hi
I am suffering from very high ping times and variable download speeds. I normally get about 15ms ping and 12-15Mb download. I am currently getting 200-500ms ping times and 1Mb-6Mb download and significant packet loss. Ping test gives me a server in holland as fastest server!
My line stats look fine - problem doesn't seem to be the local loop.
I swapped the ECI modem for a Hauwei from eBay in case that was causing an issue (and so I could access the stats) but it didn't improve things. Any clue? Do you know how to get to someone in BT that I can have a sensible conversation with? I am preparing myself for the usual long drawn out fight with the helpdesk and hours on the phone.

Could you give some advices? thanks a lot.

Hello,
If you would like to force the creation of that stats for table MSEG you need to use the -f (force) switch.
If you leave out the -f switch the parameter from stats_change_threshold is taken like you said correctly:
[http://help.sap.com/saphelp_nw70ehp1/helpdata/EN/02/0ae0c6395911d5992200508b6b8b11/content.htm|http://help.sap.com/saphelp_nw70ehp1/helpdata/EN/02/0ae0c6395911d5992200508b6b8b11/content.htm]

You have tried to do this in your second example :
==> brconnect -c -u system/system -f stats -t mseg u2013f collect -p 4
Therefore you received:
BR0154E Unexpected option value 'u2013f' found at position 8
BR0154E Unexpected option value 'collect' found at position 9
This is the correct statement, however the hyphen in front of the f switch is not correct.
Try again with the following statement (-f in stead of u2013f) you will see that it will work:
==> brconnect -c -u system/system -f stats -t mseg -f collect -p 4
I hope this can help you.
Regards.

SQL Server 2008 R2 - need help in interpreting output of statistics time on

Hi,
Could you please help me to understand how to interpres CPU and Elapsed time
I ran a query that took 1h 23 min 52 sec to complete.
My statistics time result hows the following:
CPU time = 17407152 ms, elapsed time = 5018172 ms.
Both well exceed 1h 23 min 52 sec if I consider ms to be milliseconds.
Could you please help me to understand why such mismatch?
Does ms actually mean milliseconds?
Thanks,
Andrei
SSIS question

Mostly the query is going for parallelism (running on multiple CPU) and that's why CPU time is more.
5018172 ms
5018.172 sec
83.6362 min
1.393936667 hours

Search Help problem in IT0033 (Statistics) in ECC 6

Hi All,
Iu2019m facing an error when trying to update the Statistics in HR Master Data.
I enter the Personnel no. and Infotype 33 (Statistics) and press Display button. It takes you to Display Statistics Screen.
The error occurs when I hit the dropdown button of the second line of Statistical Exceptions.
Letu2019s say that I have two Statistics (01 and 02) and the Statistical exceptions for each one.
When I hit the dropdown button to see the Statistical exceptionsu2019 list for the Statistics 01, the Search Help brings only the Statistical exception related to this Statistics (01). But, when I do the same thing for Statistics 02, the Search Help brings me all the Statistical exceptions, not only values related to Statistic 02.
Debugging the program I could see that for each dropdown the debug starts in a different point of the program.
Someone please could help me?
Thanks.

Mohan Kumar

Hi ,
Name of the workbook will be - BW Statistic 2.0 . And when u have installed Technical Content in the system it is always better to move all queries which is delivered as part of Technical Content .
Then try to load some data to Statistics cubes in development and then execute the Workbook it will be give you idea of what does indivual Query does as workbook contains graphs showing Cube Usage, Aggregate Usage etc . You can also go to each query change view and see how is it designed.
Assign Points if it helps.....

Statistics Express VI - help

Under the help option in the statistica express VI this is given to explain the time between samples (dt)
Time between samples (dt)
—Bases the calculation on the time between samples in
Signals
My design is two micophones and one sound and finding the time delay between the two.
Now does this mean it takes the difference from when one signal starts and the other starts
(say when microphone 1 first picks up a signal and then microphone 2)
Or does it show the time difference between the two signals ?
(as in the delay between the samples)
I'll attach the VI's below to see it that helps makes sense

dt is the time spacing between sampled points. In your case, dt=0.001.
If you convert to plain 1D arrays, the sampling information is lost, meaning the cross correlation in in units of the array indices. Given dt, you can calculate the the spacing in seconds from the spacing in index units.
You can also set the dt of the x-axes of the graphs so the display is in seconds.
