Why Most Of The Index's Avg_fragmentation_in_percent Doesn't Reduce After Reorganize / Rebuild Is Performed

Sep 18, 2007

I am build up a maintenance plan to reorganize and rebuild the index of one database. After that maintenance plan is performed, i found that most of indexes's avg_fragmentation_in_percent doesn't reduce. Is that any efficiency way to reduce fragmentation of the indexes?

Jun 26, 2015

We face slow performance issue for like taking long time for same query execution after We apply index rebuild and reorganize index. But, after execution of query or procedure for 2 -3 times, performance will be faster. I have following questions

1 do we need to update stats after we rebuild an reorganize index.
2. is it will be slow for 1-2 times for every query and stored procedure execution after we rebuild and reorganize index?

REBUILD Vs REORGANIZE

Sep 6, 2007

Hi all

I understand the difference between REBUILD and REORGANIZE. Just wondering if you can do both in the same script or do you have to rebuild the index first and later reorganize?

Thanks,
don

Rebuild And Reorganize

Rebuild/Reorganize Schedule

Oct 3, 2007

All,

My employer is concerned that the Rebuild/Reorganize indexes will slow down the server,will take more time and our online application users will experience slow responses. And they don't want to do off line defrag either.

So I am going to suggest to spread out the Rebuild/Reorganize indexes in such a way that rebuild/reorganize is done in small chunks rather than doing it all at once.

What do you guys think of this approach?

Thanks,

Reorganize Index

DECLARE @strIndex_Name varchar(50)
DECLARE @strTable_Name varchar(50)

SET @strTable_Name = 'DIM_AR_CLASS'
SET @strIndex_Name = 'IX_DIM_AR_CLASS_1'

PRINT @strTable_Name
PRINT @strIndex_Name

ALTER INDEX @strTable_Name ON @strIndex_Name REORGANIZE


Result msg:

DIM_AR_CLASS
IX_DIM_AR_CLASS_1
Msg 102, Level 15, State 1, Line 12
Incorrect syntax near '@strTable_Name'.

If i change the statement as below then it work fine.
ALTER INDEX IX_DIM_AR_CLASS_1 ON DIM_AR_CLASS
REORGANIZE

Anyone know why ?Does this alter index statement not support variable during execution time?
Appreciate any help.
Thanks.

Reorganize Index Task - SelectedDatabases Expression Format

Mar 19, 2007

Hi

I am trying to configure the SelectedDatabases property of the Reorganize Index Task using an expression.

The Expressions property of the task provides the ability to configure the SelectedDatabases property of the task using an expression. The properties pane shows that the type of the SelectedDatabases property should be a "(Collection)" (which is edited using the 'Object Collection Editor').

How do I create an expression to configure the SelectedDatabases property? Can I build the collection in text? Or do I need to provide a variable of type System.Object that contains a collection type (and if so exactly what type should it contain)?

TIA . . . Ed

Index Rebuild Took 9 Hrs

Jun 29, 2001

Running SQL 7.0 SP3 on P3 dual 800.

I rebuild indexes every night as part of the maintenance plan. Usually it takes about 1 hr 10 minutes on a 15 G db, last night it took 9 hrs.

I have no idea why it would take so long. Nothing changed, there were no new indexes created and none deleted.

Any ideas? I have to find out why. My boss wants an answer.

Thanks in advance.

Speeding Up An Index Rebuild....

Dec 19, 2000

Hi all...

I have a table with over 60 million rows (approx 20GB) which has an indexed column. I have tried using DBC DBReindex to rebuild the index, but after kicking it off on a friday, it is still running the following wednesday. Since managers and other finicky types access this database, that's not acceptable (it slows down their reporting).

Is there a way to speed up the reindexing process? Perhaps by adding space to the tempdb (it's 500MB) or putting it in RAM temporarily? I haven't seen any articles that specifically state that TEMPDB is used during an index rebuild, but it seems logical that it would be.

Any suggestions to speed up the process would be most appreciated!

Index Rebuild Does Not Defrag

Oct 3, 2007

Hi,

After issuing an index rebuild on a primary key index (and updating statistics), the index still shows a scan density of 12.5%!

Any ideas on why the rebuild doesn't seem to do anything on the fragmentation levels?

I'm using sql 2005

Thanx

Does Alter Index All Rebuild...

Does "Alter Index All Rebuild" rebuild just the tree level of the index? Or does it also rebuild the leaf level like reorganize?

Big Clustered Index Rebuild

Jul 25, 2007

I need to establish the storage requirements for a clustered index rebuild with SQL 05. The table is made up of the following columns



[ProductID] [int] NOT NULL,

[RegionID] [int] NOT NULL,

[TimeID] [int] NOT NULL,

[FactID] [int] NOT NULL,

[Value] [decimal](14, 4) NOT NULL



This is the clustered index :-



[RegionId] ASC,

[FactId] ASC,

[TimeId] ASC,

[ProductId] ASC



This is the result of a sp_spaceused on this particular table














name
rows
reserved
data
index_size
unused

Table
16910379278
868107368 KB
863579184 KB
3869848 KB
658336 KB



The database where this table is stored is in Simple recovery mode.



What i would really like to know is, what additional storage would i require to run the following rebuild index command.



Alter Index blah on table Rebuild



Thanks

Msg 2511 / Rebuild Index Not Working

Jun 23, 1999

Fellow MSSQL DBA's, I am stuck. I am getting a Msg 2511 on a production database. The message reads - Table Corrupt: Keys in leaf page should be in ascending order. I have dropped the offending index and rebuilt both through the application and through ISQL. Neither method fixed the problem. DBCC CHECKDB shows no errors as long as the index does not exist. I have checked out the data and see no problems. Any ideas?
Thanks very much.

Rebuild Index Task - Online Only?

Jun 19, 2008

Hi all,

In SQL Server 2005 EE I created a maintenance plan to rebuild indexes for a few large tables. I have selected five specific tables, and I'm using both "sort results in tempdb" as well as "keep index online while reindexing".

If I execute this plan for all these tables, are the indexes guaranteed to remain online? There are all different types of indexes on these tables. For example, the table "Contacts" has 8 indexes: 1 Clustered, 1 PK Unique Non-Clustered, 2 Unique Non-Clustered, and 4 Non-Unique Non-Clustered. I've heard that only certain types of indexes can remain online during a reindex (Clustered and Non-Unique Non-Clustered??).

Will SQL Server rebuild an index that isn't compatible with the online reindex mode, or will it choose to ignore it?

Thanks,

- Matt
