UPDATE STATISTICS and merry-go-round scanning

Hello everybody,
if I do UPDATE STATISTICS [table] SQL Server internally scans the table multiple times for different statistics objects (good description by Kendra Little at
http://www.brentozar.com/archive/2014/01/update-statistics-the-secret-io-explosion/).
Does anybody know whether these scans are executed parallel to each other and can profit from merry-go-round scan mechanism? (http://msdn.microsoft.com/en-us/library/ms191475.aspx).
Thanks in advance.

My impression is that they executed one by one on the same thread, but I have not researched this very closely.

Update Statistics and Rebuild of Indexes

Hi friends,
If I execute the Update statistics for a given table thru DB20 does it have any effect on the indexes of this table or is it necessary to rebuild the index using db02
Regards
Aliila

Updating Statistics does not rebuild index while in update states logs it will show you information regarding which indexes needs to be rebuiled which you can rebuild by brtools or executing rsanaora prg in se38.

Database updates statistics maintenance plan issue.

Hi team,
We are configured one job through maintenance plan that job name is “database update statistics” and database size is 280 Gb, this job executing 13 to 15 hours but job was not finished still it’s continually running.
This same job I am running through below script it’s executing within 2 hours.
Use database
Go
Exec sp_updatestats
What is the main problem if this maintenance plan.
Note: on this server no jobs and no traffic, only abc_update subpaln1 Job.

Hello,
Updating stats for whole database which is 280 G will always result in problem.It is better to run update statistics for tables and indexes which are changed frequently.
Now to your question few points which sp_Updatestas list in BOL
http://technet.microsoft.com/en-us/library/ms173804.aspx
sp_updatestats updates statistics on disabled nonclustered indexes and does not update statistics on disabled clustered indexes.
sp_updatestats updates only the statistics that require updating based on the rowmodctr information in the sys.sysindexes catalog view, thus avoiding unnecessary updates of statistics
on unchanged rows.

Update Statistics for the database MS-SQL

hi all ,
I want to run the statistics programmatically ( update statistics ) and our database is MS-SQL. Can any one tell me which is the suitable function module to do the same.
Thanks,
Ram

If you did not find this - I found the function module 'update_stats'.
How this helps
Or maybe you found somthing else?

I just had an update of Firefox, and next thing I knew, I had a message from "Mozilla Security" telling me it had found "critical process activity on my system and will perform fast scan of system files.

This is the message in the dialog box that showed up:
Firefox security alert
Scanning of your system is currently on, please wait until the end. Your system affected by numerous virus attacks, Mozilla Firefox recommends you to install proper software to protect your computer
Quick scan system:
Scan complete
Number of scanned objects: 3676
Number of infected objects: 97
It then directs me to Click "Start Protection" button to erase all threats. If I do that, an install program window pops up with: installInternetDefender_143.exe
from http://monozsa.ce.ms
I don't automatically click on those unless I know they are legitimate. I'm just concerned that the security issue came about after I received an update to my Firefox.
I already have a security program installed on my computer through my internet provider--why would it not have picked up these infected objects? Is this legitimate? It

The scanning is most likely an animation and not a real scan. 
As long as you didn't download and install that program then you should be safe.
To be sure you can do a malware check with some malware scanning programs. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

PSAP SID TABLESPACE UPDATE STATISTICS ADVANTAGES AND DISADVANTAGES

Dear All,
Can anyone explain me if we select PSAP SID table space only for update statistics from DB13 Instead of selecting all tables for update statistics,what are the advantages and disadvantages of selecting only PSAP SID tablespace .
I will be glad if you can suggest any related sapnote or sapmaterial.
we are working on SAP ECC5 and oracle version id 9i and operating system is windows.

Hi arunkumar ,
When you are updating statitics then update for all table space why for one only.After all it will increase the performance of your database.

UPDATE STATISTICS WITH FULL SCAN - High reads than normal

Hi
Update statistics when it runs with full sampling, reads high amount of data. my database size is 300GB and update stats is reading TBs of data from the data drive. Did anyone come across this wierd scenario?
Thanks
Vicky
Thanks

I have been running US on 1 TB database and did not notice high reading.... It does not block anyone but you may notice some performnace degradation...
Have you tried Ola's great utility
EXECUTE dbo.IndexOptimize @Databases = ‘USER_DATABASES’,
@FragmentationHigh_LOB = ‘INDEX_REBUILD_OFFLINE’,
@FragmentationHigh_NonLOB = ‘INDEX_REBUILD_ONLINE’,
@FragmentationMedium_LOB = ‘INDEX_REORGANIZE_STATISTICS_UPDATE’,
@FragmentationMedium_NonLOB = ‘INDEX_REORGANIZE_STATISTICS_UPDATE’,
@FragmentationLow_LOB = ‘NOTHING’,
@FragmentationLow_NonLOB = ‘NOTHING’,
@FragmentationLevel1 = 5,
@FragmentationLevel2 = 30,
@PageCountLevel = 1000
How does all this work?
Indexes with a fragmentation over 30% are rebuilt, online if possible.
Indexes with a fragmentation between 5% and 30% are reorganized and also have their statistics updated.
Index with a fragmentation under 5% (or a size of under 1000 pages) are ignored.
It is available on http://ola.hallengren.com.

tell us what actions you take to get Apple not to recognize your email address...
Are you formatting it correctly? - username @ someDomain .com <- NO Spaces (I did it so the system wouldn't make an email link out of it)

CBO and Update Statistics

Hi ,
Ver. 10204
The cbo usually working very well when it have an update statistics ,
Orcale also recommand to manually gather statistics after bulk loading.
Could one show simple TEST CASE where oracle is choosing a poor execution plan due to non update statistics?
Thanks

Update statistics with 640_EX2 kernel

Hello,
I'm no longer able to do UPD_CHECK, UPD_COND and UPD_UNCOND since upgrading to a 640_EX2 kernel.
This happens on WebAS 6.20 on Linux IA32 and on WebAS 6.40 on Linux X86_64. Scheduling backups and verifys still works from db13. MaxDB version is 7.6.4.07. The problem exists with versions 120 and 212 of dbadaslib.so.
Are these commands working for anyone? I suspect this could be one of these nice C++ ABI incompatibility problems, because libSQLDBC76.so is linked against libstdc+.so.5 and dbadaslib.so is linked against libstdc.so.5 and libstdc+.so.6.
Since I am on an unsupported Linux distro I would like to know whether this happens on supported distros, too.
Thank you,
Sebastian

Thank you for pointing me to the logs again, I scanned them too superficially last time.
This is written to the trace file of a batch process:
C Starting Update Statistics on connection 2 ...
C *** ERROR => connection for UPDSTAT is not available
[dbupdsdb.cpp 140]
This is interesting, because the connection test in db59 is successful for all 4 types of connections.

SQL 2008 R2 Best Practices for Updating Statistics for a 1.5 TB VLDB

We currently have a ~1.5 TB VLDB (SQL 2008 R2) that services both OLTP and DSS workloads pretty much on a 24x7x365 basis. For many years we have been updating statistics (full scan- 100% sample size) for this VLDB once a week on the weekend, which
is currently taking up to 30 hours to complete.
Somewhat recently we have been experiencing intermitent issues while statistics are being updated, which I doubt is just a coincidence. I'd like to understand exactly why the process of updating statistics can cause these issues (timeouts/errors). My theory
is that the optimizer is forced to choose an inferior execution plan while the needed statistics are in "limbo" (stuck between the "old" and the "new"), but that is again just a theory. I'm somewhat surprised that the "old" statistics couldn't continue to
get used while the new/current statistics are being generated (like the process for rebuilding indexes online), but I don't know all the facts behind this mechanism yet so that may not even apply here.
I understand that we have the option of reducing the sample percentage/size for updating statistics, which is currently set at 100% (full scan). Reducing the sample percentage/size for updating statistics will reduce the total processing time, but
it's also my understanding that doing so will leave the optimizer with less than optimal statistics for choosing the best execution plans. This seems to be a classic case of not being able to have one’s cake and eat it too.
So in a nutshell I'm looking to fully understand why the process of updating statistics can cause access issues and I'm also looking for best practices in general for updating statistics of such a VLDB. Thanks in advance.
Bill Thacker

I'm with you. Yikes is exactly right with regard to suspending all index optimizations for so long. I'll probably start a separate forum thread about that in the near future, but for now lets stick to the best practices for updating statistics.
I'm a little disappointed that multiple people haven't already chimed in about this and offered up some viable solutions. Like I said previously, I can't be the first person in need of such a thing. This database has 552 tables with a whole lot more statistics
objects than that associated with those tables. The metadata has to be there for determining which statistics objects can go (not utilized much if at all so delete them- also produce an actual script to delete the useless ones identified) and what
the proper sample percentage/size should be for updating the remaining, utilized statistics (again, also produce a script that can be used for executing the appropriate update statistics commands for each table based on cardinality).
The above solution would be much more ideal IMO than just issuing a single update statistics command that samples the same percentage/size for every table (e.g. 10%). That's what we're doing today at 100% (full scan).
Come on SQL Server Community. Show me some love :)

I got update 23 and then it cks if all add ons are ok. But every time I turn firefox on it keeps recking if add ona are good. How do i stop firefox from cking??

Hello I got update 23 and when it finished and restarts it cks all my add on's and then its ready to finish updating. but this update the cking for good add ons keeps scanning each time i turn on firefox. so the 1st part of the 2 part scans ok but when it scans the 2ed part to ck add ons it does not finish and just goes away so then every time i turn on friefox it keeps doing this instead of laoding my home page firefox keeps opening up and then the firefox home page opens when i have my home page set to open up my yahoo acct. how do i get 23 update to stop scanning my 10 add ons and will then finish installing so my windows 8 laptop will get past this problem?? I hope U can tell me what to do and all my add ons are ok and my extensions are all good too!! thanks for helping me??

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the extensions.* files (e.g. extensions.sqlite, extensions.ini) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
*https://support.mozilla.org/kb/Profiles
New files will be created when required.
See "Corrupt extension files":
*http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
*https://support.mozilla.org/kb/Unable+to+install+add-ons
If you see disabled or not compatible extensions in "Firefox/Tools > Add-ons > Extensions" then click the Tools button at the left end side of the Search Bar ("Find Updates" button in older Firefox versions) to check if there is a compatibility update available.
If this hasn't helped then also delete the addons.sqlite file.
You can also check for problems with preferences. 
Rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default value.

How do I dispute a copyright claim against a video i made using a trailer in iMovie? The only content I used was the video I shot of friends daughter on a merry-go-round.IMovie had the music etc that I used. Here's the message It gives a number of options to choose from if I want to dispute the claim but I don't know which one this would come under. Several obviously don't apply and of the ones left I don't know which content that is in IMovie that I use comes under. "This video is my original content and I own the rights to it" "I have a license or written permission of the property rights holder to use this material" "My use of the content meets the legal requirements for fair use of fair dealing under applicable copyright laws" or "The content is in the public domain or is not eligible for copright protection."

You want to use the "I have a license..." option, since clearly the music is not yours, but Apple has granted you a license.
For your license, see this document, section 2.M. http://images.apple.com/legal/sla/docs/iMovie.pdf
For more on this irritating problem and why it is so hard to solve, see this article. (It is a problem for Final Cut Pro users as well.)
