Error While Rebuild Indexes
Sep 21, 2015
We have a script running everyday for rebuild and re-organisation of indexes. But, somehow its getting failed. Attached script for your consideration. There is no database name with amoperations. There is table called DatabaseObjectAudit but it exist on master db.
Message:
-->Start Index Maint
-> Gathering fragmentation information (can take a while!)
-> Gathering COMPLETE : Total of 43 databases were found.
-> Gathering COMPLETE : Total of 1622 indexes were found.

I have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.
In order to do that, I have taken the records based on the fragmentation %.
But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.
create table #fragmentation
(
FragIndexId BigInt Identity(1,1),
--IDENTITY(int, 1, 1) AS FragIndexId,
DBNAME nvarchar(4000),
TableName nvarchar(4000),
[Code] ....

Hi All,
SQL 7 REQUIRES THE DBA TO MANAGE THE INDEXES AND IN PARTICULAR THE FILL FACTOR AVAILABILITY. DOES SQL SERVER 2000 AUTOMATICALLY ADDRESS THIS OR DO WE STILL HAVE TO PERIODICALLY RUN,
sp_MSforeachtable @command1="print '?' DBCC DBREINDEX ('?')"
TO REBUILD ALL INDEXES IN THE DATABASE?
Thanks in advance,
-Praveena

Hi!
I'm not a dba at all, just a simple developer but I have got the assignment to help out with performance problems on a db.
I noticed that almost all indexes are fragmented 75-99%. Can I rebuild them when the database is in use? Can I reorganize indexes when the db is used?

In the maintance plans there is a Rebuild Index choice.
If u choose tables and views the plan executes
ALTER INDEX <index> ON <table> ;REBUILD
for all indexes in the datebase.
I am currently using this plan on our production DB, scheduled for every Saturday night.
I wonder if there is a downside of using maintance plans. Because it seems to be doing the job. Any comments?

So I'm reading http://www.sql-server-performance.com/tips/clustered_indexes_p2.aspx and I come across this:
When selecting a column to base your clustered index on, try to avoid columns that are frequently updated. Every time that a column used for a clustered index is modified, all of the non-clustered indexes must also be updated, creating additional overhead. [6.5, 7.0, 2000, 2005] Updated 3-5-2004
Does this mean if I have say a table called Item with a clustered index on a column in it called itemaddeddate, and several non-clustered indexes associated with that table, that if a record gets modified and it's itemaddeddate value changes, that ALL my indexes on that table will get rebuilt? Or is it referring to the table structure changing?
If so does this "pseudocode" example also cause this to occur:
sqlstring="select * from item where itemid=12345"
rs.open sqlstring, etc, etc, etc
rs.Fields("ItemName")="My New Item Name"
rs.Fields("ItemPrice")=1.00
rs.Update
Note I didn't explicitly change the value of rs.fields("ItemAddedDate")...does rs.Fields("ItemAddedDate")=rs.Fields("ItemAddedDate") occur implicitly, which would force the rebuild of all the non-clustered indexes?

I have a number of databases that are being transactionally replicated from SQL 2000 Enterprise edition publisher to SQL 2005 Enterprise edition subscriber. I have included indexes in the replication. The subscriber database is then accessed and the data de-normalised and aggregated for reporting purposes.
My question is this: I want to periodically re-build the indexes on the publisher and subscriber via an automated task. If I rebuild the indexes on the publisher, will that automatically replicate to the subscriber? Will there be a problem with the "snapshot being out of date", and therefore replication stopping? I run a new snapshot once a day in the small hours of the morning. If there is likely to be a problem with the rebuild throwing the replication out, would it be wise to have the rebuild job running just before the new snapshot is taken?
Any help/advice appreciated.

Hi All.
Our inhouse app used to run on a SQL2000, but we've recently moved it to 2005.
The move was done by way of backup and restore (it was on a whole new server).
After the move, an odd problem showed up: once in a while, the server seems incapable of finding/using its indexes: everything starts working slowly, until I run a maintenance plan that rebuilds its indexes etc.
In the database/server all relevant options seem to be ok (auto update statictiscs etc.), and my conclusion that it doesn't use its indexes comes from the fact that:
* it gives the results from certain select statements in a totally different order (although the set of rows is the same),
* performance is (all of a sudden) very slow (seconds turning to minutes!!)
This happens:
* at least after a reboot of the server
* sometimes just in the middle of the day
The only way I've found to solve the matter, is by running the maintenance plan to rebuild the indexes, but sometimes this only seems to work the second time.
Does anybody share this experience, or know what to do about it?
Thanks,
Nick.

We are planning to standardize our newly deployed sql server, As a part of it we have configured 2 maintenance plans 1) Update Statistics which runs daily and 2) Index Reorganize which runs on weekly.
Apart from above, any other things to be in place for better maintenance of the sql server.
Also, how to Index Rebuild activity for clustered indexes requires any downtime.

Do I need to rebuild my indexes on my High Availability listeners?
When I do a full index rebuild on my primary DB's. Does rebuilding also send the rebuild to the listener(s)?

If I rebuild some indexes that are above 30% of average fragmentation, should I after that update statistics?
Also, How can I see if I Need to update statistics^on the tables of my database?

Normally we use rebuild, reorganize indexes when it is required, I used a SQL job using maintenance plan to run daily and rebuild, reorganize indexes and update statistics but I do not know if it runs either they are required or not. Should this plan automatically execute the build upon required indexes to be rebuild or it fires either they are required to be executed or not.

I am performing a Rebiuld of the Master database using the REBUILDM utility on a SQL 2000 SP3 database which is clustered.
The utility starts off correclty, copying the correct MDF and LDF files to the hard drive, and the configuration bar goes across the screen 4 times, before giving the following error "Rebuild master failed with error -1".
I can't find anything on microsoft. I followed KB-298568 to perform this process, but the SQL Service will now not start as it cannot find the master, as it did not get rebuilt properly.
I have included screen shots of the error, in the zipped up word doc.

I copied the master's .ldf from Node 2. Now I get this error:

Looks like I'm screwed. Next problem - can you rebuild the master.mdf without the mastlog.ldf and how? Also, on an active/active SQL server setup, how would you re-install Node 1?
Help!

My site crashed, so I had to rebuild the Project Site.
I used the SharePoint products and technologies configuration wizard to disconnect from the server farm (only actually running on the single server).
I then reran SharePoint products and technologies configuration wizard to setup the site.
Configured the Project Service and attached to the existing dB's.
Previously, I used the url http://servername.domain.forest/PWA/default.aspx .
Now when I attempt the use the same URL, I get the following error:
"An unexpected error has occurred"
I have tested this one 3 servers now and I receive the exact same result. Is there a path I should apply to the servers in order to allow fully qualified server names after a reinstall of the system?

I was updating few indexes in one of my database tables when I got this warning message:
"Warning! The maximum key length is 900 bytes. The index 'IX_cc_statusText' has maximum length of 1024 bytes. For some combination of large values, the insert/update operation will fail."
Can anyone help me out as to:
1. Why this warning was thrown?
2. What are the implications of the same?
3. How to rectify this?
Here is the script I was using to update the indexes:
CREATE INDEX [cc_programEnrollment14] ON [dbo].[cc_programEnrollment]([cc_company_uid]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_program_uid] ON [dbo].[cc_programEnrollment]([cc_program_uid]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_status_uid] ON [dbo].[cc_programEnrollment]([cc_status_uid]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_CompanyID] ON [dbo].[cc_programEnrollment]([cc_CompanyID]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_statusText] ON [dbo].[cc_programEnrollment]([cc_statusText]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_initiatedDate] ON [dbo].[cc_programEnrollment]([cc_initiatedDate]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_initiatedBy_uid] ON [dbo].[cc_programEnrollment]([cc_initiatedBy_uid]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_SponsorID] ON [dbo].[cc_programEnrollment]([cc_SponsorID]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_SponsorDistributor_uid] ON [dbo].[cc_programEnrollment]([cc_SponsorDistributor_uid]) ON [PRIMARY]
GO
CREATE INDEX [IX_cc_programEnrollment] ON [dbo].[cc_programEnrollment]([cc_isDealerEligible], [cc_uid]) ON [PRIMARY]
GO
Thanks in advance

I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?

I had to reinstall sql 6.5 on my server. However I am not sure of the correct sequence to resetup my databases. I have all of my original database devices and backups. However when reinstalling I no longer see the database devices or databases( excepected). How do I recreate my database devices using the devices that I have on an existing device. I need sql to recognize these devices then I can recreate my databases and do my restores. Please help!

Dear all,
I have a SQL Server 7 box that is shortly to be rebuilt completely (still on NT4, but with new RAID system), does anyone have any advice on how I can make the transition as painless as possible? Particularly, I want to maintain the backup, security and DTS structures as much as possible.
Thanks in advance

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.

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?
