Reindexing and Update Statistics on Standby Server

In an environment where we have enabled Always On, we have configured a Maintenance Plan that constitutes on the following sub plans: a. Reindexing b. UpdateStatistics and c. Integrity Checks. However, for the databases that are getting synchronized on
the Standby Server (they are on "Synchronizing" mode), can we also configure the same Maintenance plan in the standby server. Will there be a problem in running these jobs on the databases that are in "Synchronizing" mode?

The standby/replicas databases are either in read-only or constant recovery mode and, therefore, no data modification can be performed. This includes running maintenance jobs such as reindexing and updating of statistics. The better approach here is to
use a custom maintenance script, such as that from
Ola Hallengren, that only reindex those that are necessary to minimize the amount of transaction log records generated on the primary and keep the standby in synchronized state.

Is reindexing and rebuilding statistics nessiary

I'm reducing the size of a SQL database from 115905 records to about 110000 records. My SQL server administrator is nowhere to be found. Is it critical to have the database rebuild
indexes and update statistics before I let users get back into the front end application and do regular work?
I've been doing these archives daily for a week and he rebuilds indexes and updates statistics each day before I let the users get in.

Since you deleted large no of records updatiing stats would be a good option .And if you rebuild index with full scan,which i dont think would be necessary to do after delete process,stats would automatically be updated .
More or less index rebuild depends on fragmentation >30 % you rebuild and between 30 and 10 you reorganize.
Since it is your daily task I would suggest you to look at Ola hallengren script

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 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.

IF Auto Update Statistics ENABLED in Database Design, Why we need to Update Statistics as a maintenance plan

Hi Experts,
IF Auto Update Statistics ENABLED in Database Design, Why we need to Update Statistics as a maintenance plan for Daily/weekly??
Vinai Kumar Gandla

Hi Vikki,
Many systems rely solely on SQL Server to update statistics automatically(AUTO UPDATE STATISTICS enabled), however, based on my research, large tables, tables with uneven data distributions, tables with ever-increasing keys and tables that have significant
changes in distribution often require manual statistics updates as the following explanation.
1.If a table is very big, then waiting for 20% of rows to change before SQL Server automatically updates the statistics could mean that millions of rows are modified, added or removed before it happens. Depending on the workload patterns and the data,
this could mean the optimizer is choosing a substandard execution plans long before SQL Server reaches the threshold where it invalidates statistics for a table and starts to update them automatically. In such cases, you might consider updating statistics
manually for those tables on a defined schedule (while leaving AUTO UPDATE STATISTICS enabled so that SQL Server continues to maintain statistics for other tables).
2.In cases where you know data distribution in a column is "skewed", it may be necessary to update statistics manually with a full sample, or create a set of filtered statistics in order to generate query plans of good quality. Remember,
however, that sampling with FULLSCAN can be costly for larger tables, and must be done so as not to affect production performance.
3.It is quite common to see an ascending key, such as an IDENTITY or date/time data types, used as the leading column in an index. In such cases, the statistic for the key rarely matches the actual data, unless we update the Statistic manually after
every insert.
So in the case above, we could perform manual statistics updates by
creating a maintenance plan that will run the UPDATE STATISTICS command, and update statistics on a regular schedule. For more information about the process, please refer to the article:

Please help me to resolve the issue.

some of your PSA tables are inconsistent - ex: /BIC/B0000228000 - check PSA partitioning in RSRV to correct the same or delete data from the same using SE14 and try running the same.

I forgot my password and am trying to reset my ipod, but it won't work.It says that my ipod is in recovery mode and that I must restore it. I click ok, and then click on restore and update. Then it says connecting ipod software update server and a screen pops up with ipod software update on the top and iOS 5.1. It lists a bunch of stuff this update contains and on the bottom it says next, which I click and nothing happens, it just goes back to the ipod restore page. Help, what am I doing wrong?

Update to the latest version of iTunes. Mac OS X 10.5.8 (Leopard) users may need to download iTunes 10.6.3.
Third-party security software or router security settings can also cause this issue. To resolve this, followTroubleshooting security software issues.
Downgrading to a previous version of iOS is not supported. If you have installed software to performunauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. Uninstall the unauthorized modification software from the computer.
Edit out the "gs.apple.com" redirect from your hosts file, and then restart the computer for the host file changes to take affect. For steps to edit the Hosts file and allow iTunes to communicate with the update server, see iTunes: Troubleshooting iTunes Store on your computer, iPhone, iPad, or iPod—follow steps under the heading Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store. If you do not uninstall the unauthorized modification software prior to editing the hosts file, that software may automatically modify the hosts file again on restart.
Avoid using an older or modified .ipsw file. Try moving the current .ipsw file (see Advanced Steps > Rename, move, or delete the iOS software file (.ipsw) below for file locations), or try restoring in a new user to ensure that iTunes downloads a new .ipsw.

1. After downloading the firmware from the given link, open iTunes and click on your device.
2. Now press SHIFT on your keyboard and while pressing it click on "Restore".
3. A dialog box will appear.
4. Select the firmware you downloaded and click ok.
5. Done!!! Your iPhone will now be restored to 5.1.1 and if you had backed up your iPod before, then you can put all its settings afterwards.

Mail constantly is synchronising with server and updating cache directory!

Mail constantly is synchronising with server (sent messages) and updating cache directory making everything slow.
I have a .mac account. I understand the concept of IMAP and that it information is stored on the server therefore it needs to update but surely not constantly and besides the blue bar sticks halfway through without completing. Please help.

I have had the same issue. Rebuilding fixes it temporarily, but it comes back....Also have an issue where Mail will not download attachments automatically. They show up in grey until they are clicked...have Mail set to download all messages and their attachments, but it doesn't want to. Very frustrating. I have begun the switch to Entourage, which is unfortunate, as I like Mail more.
