Why Most Of The Index's Avg_fragmentation_in_percent Doesn't Reduce After Reorganize / Rebuild Is Performed
Sep 18, 2007I 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?

Reorganize Data And Index Pages
Jul 23, 2005Hello all,SQL 2000 on Windows 2000. If I go into all tasks, maintenance plan, itgives me an option to reorganize data and index pages. When I check onit, it populates the line "change free space per page percentage to" andputs in 10 in there. Is this the default for free space? Is it thedata pages that will have 10% free space or just the index pages? Aredata and index on the same pages?Thanks,Raziq.*** Sent via Developersdex http://www.developersdex.com ***

Reorganize Index Task - SelectedDatabases Expression Format
Mar 19, 2007Hi
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)?

Index Rebuild Took 9 Hrs
Jun 29, 2001Running 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, 2000Hi 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!

Transact SQL :: Index Rebuild MP
Oct 12, 2015I would like to completely understand the difference between index rebuild Maintenace plan and the customized script.Maintenance Plan rebuilds every single index.It will take the long time as it checks every index.If we use a custom script as a job, it will rebuild the index which has fragmentation >30%.So that, the job will not take much time.

Msg 2511 / Rebuild Index Not Working
Jun 23, 1999Fellow 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, 2008Hi 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
