DBCC DBREINDEX Running Out Of Room
May 16, 2000
I am trying to reindex a large table, and cannot because there isn't enough room on the the primary filegroup. the database consistes of one physical file in the primary filegroup. the table is over 50% of the size of the database. When the table is less than 50% of the size of the database, I do not see this problem.
BTW, the only index on the table is the primary key which consists of two columns, one is an integer and the other datetime.
It seems as if SQL server needs 1x the current size of the table to be free in order to reindex? Is this the case?
It is not an option for me to allow the database to autogrow. Is there anything else I can do?
Thanks for your help!

I'm running a simple DBCC DBREINDEX ('myTable') and I receive thefollowing error:"Server: Msg 169, Level 15, State 2, Line 2A column has been specified more than once in the order by list.Columns in the order by list must be unique. DBCC executioncompleted. If DBCC printed error messages, contact your systemadministrator."I can successfully reindex other tables in this database. I thoughtthat perhaps I had objects in the database that ended up with the samename, but I've pretty much ruled that out.Any suggestions?ThanksJohn D. Morrismailto://jmorris_42@hotmail.com

What factors would make you decide to use DBCC DBREINDES instead of DBCC DEFRAG when you notice index defragmantation?
Thanks.

Hi my data files sit in the default directories and I think they are causing my partition to run out of space. I mainly use one db that I created but don't use the others (ie master, model, tempdb, etc). Yet I see their MDF and LDF files are growing. What can I do to shrink them down or perhaps move them off to a larger partition after shrinking?

We are new to SQL Server and we are currently setting up a job that
does a dbreindex for tables that need it. I got the scripts for this
from swynk. 50 of the tables that needed a dbreindex,
(under 90% scan density) were not impacted by running the dbreindex.
I.e., I ran the dbreindex and it left it at 50% scan density.
The fill factor for these tables is set to 100%.
I tried update stats, updateusage...nothing changes....
I am sure there must be a logical reason as to why the dbreindex
had no impact on these tables. Does any one have any info on this?
Thanks in advance!

I am executing a DBCC DBREINDEX for a table with about
4 million rown in SQL6.5. I has run for about
15 hrs now and is till running.
The index is the PK for the table and it is clustred index.
I ran it on a non clustered index on the same table and it ran for a couple of hrs.
Does any one have any idea how much time it might take for the clustered index?
I heard that this process might take more time and for one of my friends it ran for more than 40 hours.
I don;t have so much if time as th DB has to go for production to night and if not it might effect our businees.
I cancelled DBCC DBREINDEX before by killing the process and the master.DAT file got corrupted.I had to restore everytihng. Does anyone know any work around?
Help appreciated.
Thanks.

Hi,
I wanted to know is DBCC DBREINDEX is a logged operation?
The reason why I am asking this is, Whenever we create an index or drop an existing it is a logged operation. Is this the same when we do DBCC DBREINDEX? Is it drops existing indexes and creates new indexes. My concern here is about transaction log. If I run a DBCC DBREINDEX on a huge table with lot of indexes, Is it going to fill transaction log?
Any help is appreciated!
Thank you,
Ravi.

About how long should I expect this to run? The Database is 200MB. The table I doing the reindex on has about 800 rows. Is an hour outrageous.. ?

Hello!
SQL Server 7
After database clean up (removing old data)I run dbcc dbreindex.
Is it true I don't need to run UPDATE STATISTICS after DBCC DBREINDEX as since SQL Server 7 runs UPDATE STATISTICS automatically (after dbcc dbreindex).
Thank you.

Hi All,
I have a following script:
DECLARE @TableName sysname
DECLARE cur_reindex CURSOR FOR
SELECT table_name
FROM information_schema.tables
WHERE table_type = 'base table'
OPEN cur_reindex
FETCH NEXT FROM cur_reindex INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT 'Rebuilding indexes ' + @TableName + ' table'
DBCC DBREINDEX (@TableName, ' ', 10)
FETCH NEXT FROM cur_reindex INTO @TableName
END
CLOSE cur_reindex
DEALLOCATE cur_reindex
GO
I added as a step in the job. However, when I run it I get an error message:
Msg 2501, Sev 16: Could not find a table or object named 'table_1'. Check sysobjects. [SQLSTATE 42S02]
When I run
SELECT table_name
FROM information_schema.tables
WHERE table_type = 'base table'
table_1 is the first on list. Any idea why I am getting this error message?

Has anyone had the problem with DBCC DBREINDEX on a table/index not doing anything.
You just get the usual "DBCC execution completed. If DBCC printed error messages, contact your system administrator." message.
I have tried:
DBCC DBREINDEX ('<table_name>')
DBCC DBREINDEX (<table_name>)
DBCC DBREINDEX ('<table_name>', '')
DBCC DBREINDEX ('<table_name>', '<index_name>')
DBCC DBREINDEX ('<table_name>', '<index_name>', 80)
Maybe its "optimising" and not thinking anything needs updating.
Should I look for an alternative way of rebuilding an index like dropping and recreating?
The beauty with DBCC DBREINDEX ('<table_name>') would have been that I was going to get the list of user tables in the database and call it for each table to simply rebuild all indexes.

I have a stored proc that identifies indexes that need to bedefragmented ( LogicalFragmentation > 20% ) using DBCC SHOWCONTIG.This works fine and shows me all of the candidate indexes to bedefragged. I am using DBCC DBREINDEX to rebuild the indexes. What Inoticed yesterday is that it seems that DBREINDEX is not actually doinganything. I would check the target indexes, run DBREINDEX, then checkagain. The same list of indexes came up unchanged.What is strange is although I am not specifying "WITH NO_INFOMSGS" thisis the only output from the DBREINDEX:"DBCC execution completed. If DBCC printed error messages, contact yoursystem administrator."According to BOL DBREINDEX should return a result set if "NO_INFOMSGS"is not specified, but if "NO_INFOMSGS" is supplied the prior message iswhat is returned. This doesn't seem to be working correctly, or if itis, I have no idea where any error messages are being returned.Anyone have any ideas?

Hi,
I've previously raised a thread about an index corruption issue we are getting on an infrequent basis. We are running SQL 2000 SP4, patched up with latest hotfixes on a cluster.
Yesterday, we experienced the corruption again. In the past, running DBCC DBREINDEX on the corrupted index has fixed the problem.
However, this time, even though DBCC DBREINDEX reported that it completed successfully, the corruption remained (proved by running DBCC CHECKTABLE on the index).
First question:
We created an identical index, with a different name, using the CREATE INDEX command, but this was created with the same corruption. Does SQL Server try and be clever and say "this index is the same as another, so I'll just copy that one instead of creating a new one" ? This is what would appear to be the case.
We then dropped the index and then recreated it. This time the index was fine.
Second question:
My understanding of DBCC DBREINDEX is that it drops and recreates the index. As manually dropping and recreating the index worked but DBCC DBREINDEX didn't I can only assume that this isn't the case. So what does it do?
This then begs a third question that, as I've been 'fixing' the issue in the past by running DBCC DBREINDEX, is it possible that it fixes it enough for DBCC CHECKTABLE to think it's been fixed, but deep down the problem has remained which is why the index has continued to corrupt a few weeks down the line?
If anyone can help answer these questions that would be really useful.
Thanks.

I have lost the reference but I read somewhere that when running DBCC DBREINDEX against a clustered index, all the secondary indexes on the table are automatically re-indexed as well. I did a test of this on a small table and it seemed to confirm this. However, now I've put this into practice, I am finding that it doesn't seem to work this way. I noticed that having run DBCC DBREINDEX against a table's clustered index (DBCC DBREINDEX ('tablename', 'clusteredIndexName', fill_factor)), the secondary indexes were not automatically re-indexed - as born out by the fact that they remained badly fragmented.
First of all, do the dba's who read this beleive it is correct that DBCC DBREINDEX run against a clustered index will automatically rebuild the secondary indexes too? If so, why wouldn't it work in all cases?

Normally, after I use DBCC DBREINDEX, I can be sure that Scan Density on a clustered or non-clustered index is very good - eg. 99% or 100%. However, I have one database where there are a number of indexes that are not showing any improvement in Scan Density after running DBCC DBREINDEX. In on case, a clustered index, I run it on two days in succession and Scan Density actually go worse! Can anyone give me a reason for this? Can anyone suggest how to fix it?

Hi,
I am facing a rather peculiar issue where I am getting a floating point exception error while rebuilding index for a particular table.
--------
Error Number : 3628
Message :
[Microsoft SQL-DMO (ODBC SQLState: 42000)] Error 3628: [Microsoft][ODBC SQL Server Driver][SQL Server]A floating point exception occurred in the user process. Current transaction is canceled.
[Microsoft][ODBC SQL Server
------------
This seems to be a rare issue ( as acknowledged by microsoft ) and they seem to suggest that it happens with SQL Server 2000 SP3 . I migrated my database into an SQL Server 2000 SP4 and started the rebuild again .. .. But it still failed with the same error ..
Am just hoping the microsoft guys are wrong and many of you have actually faced this stuff before.. Please let me know.
Thanks in advance,
Ranjit.

Microsoft states that dbcc DBREINDEX automatically updates statistics but INDEXDEFRAG does not. If this is the case, does MS mean that only the affected statistics are updated or all statistics? Also, is it a good idea to run 'Update Statistics' after doing INDEXDEFRAG?

Every time I execute DBCC DBREINDEX (Table_Name, '',0)WITH NO_INFOMSGS the server hangs. No error messages in windows 2000 logs or in the SQL 7.0 logs.
The table is about 2 gig in size and the index is a clustered index on two fields.
The server has 1 gig of memory and the cache hit ratio, and cache flushes both look good. Any ideas? Any help would be greatly appreciated.

What can I do to make the maintenance job run successfully, size of the tempdb database is only 50GB and recovery model is set to simple. It cannot be increased as the mount point on which it is residing is 50GB.
