Folks
Our sql server machine is badly in need of a defrag however I'm a bit weary of doing this as I'm really not sure of the implications or indeed how to do it.
I'm really not a server type of person so any assistance would be gratefully received. If anyone can explain it to me like I'm a 5 year old then that would probably be best!
Cheers
Hi everyone, I am fairly new with SQL Server and need a little bit of help in regards to boosting my SQL servers performance. I have been advised that defraging SQL Server will definitely help solve my issue however I have never performed this function before. Can someone please help guide me through the necessary steps to execute this task. Thanks in advance.
View 5 Replies View RelatedI have been reading many things on the internet and I wanted to create a thread asking my question here. We currently do all the re-indexing and show contig's etc to maintain my sql data and to ensure everything is good to go there.
My question is, what about the physical drive and data. We house our mdf's on a raid 1_0 and our ldfs on raid 5. I am wondering if I need to defrag these drives b/c if not am i impacting my I/O on that box. If so should I stop the sql service so that it does not corrupt SQL data? Any help on this topic would be great.

I have a large table with no PK but has other indexes. How to defrag the table (not the indexes)? Do I need to drop and re-create the table or something?
Thanks.
Hello,
I am working with a very large db (850+gig) that is in desperate need of defragging. I am familiar with DBCC Reindex and DBCC IndexDefrag but am concerned that these processes will take an extremely long time to run. Has anyone had any experience with any 3rd party tools that better/faster then DBCC? Or any ideas or suggestions how best to attack this? Among the many tables with large footprints and millions of rows, I have 3 tables with reserved space over 100g also 3 tables with over 500Mil rows (1 tbl with > 1bil rows). This is a 24x7 db.
Thanks in advance for any ideas and suggestions

Hi
Can I de-frag the Drive in which the Data files & Log Files of the SQl Server Exists ???
Please Advice.

Isn't there any way to automate Windows defrag? Isn't there any undocumented parameters for DEFRAG.EXE?

I#ve been doing disaster recovery on a web box that died today.
So I thought I'd do some "downtime" maintenance on the DB server
I ran a BDREINDEX on all tables, all indexes. (I know this is the 2000 way, but I assume its as good as the proper 2005 way??).
5 minutes on a 10GB database. Not bad!
I checked the DEFRAG and UPDATE STATS processes that run overnight.
They are basically defragging only tables with SHOWCONTIG indicating fragmentation. And then doing an UPDATE STATISTICS WITH FULLSCAN on all tables
That is taking an average of 30 minutes ...
Is DBREINDEX the equivalent of an UPDATE STATISTICS WITH FULLSCAN, or is it in some way a smaller-sample version?
I'm wondering why I don't just lock the DB and do a REINDEX of everything in 5 minutes ...

I am new to sql server and we have sql server 2000
DBCC INDEXDEFRAG ( 0, PS_ORD_LINE, PS_ORD_LINE )
DBCC INDEXDEFRAG ( 0, PS_ORD_LINE, PS0ORD_LINE )
DBCC INDEXDEFRAG ( 0, PS_ORD_LINE, PSAORD_LINE )
DBCC INDEXDEFRAG ( 0, PS_ORD_LINE, PSBORD_LINE )
DBCC INDEXDEFRAG ( 0, PS_ORD_LINE, PSCORD_LINE )
DBCC INDEXDEFRAG ( 0, PS_ORD_LINE, PSEORD_LINE )
DBCC INDEXDEFRAG ( 0, PS_ORD_LINE, PSFORD_LINE )
Please somebody give me for sql server 2005 scripts for above.
I'd like to build a process that will identify all the tables in a database with a scan density less than 100% and generate 'dbcc dbreindex' statements for them. The 'dbcc showcontig' command displays the information I want but I don't know how to access this information from within a script. Any ideas out there?
View 5 Replies View RelatedHow do we defrag indexed views? Can any one give me a query to loop thru all the indexed views in the database and find out the fragmentation levels and also defrag them?
Thanks in advance!
I've noticed a huge transaction log size after having run an
index defragmentation. Does a defrag get written to the transaction
log really? (Assuming the full recovery model.)
Is there any easy way to defrag a table with no clustered idx other than bcp out then back in ? (SQL 2000)Actually I have a 100GB db that I deleted data from other tables, about 10GB worth, but access to the table in question (38GB) seems to have slowed down dramatically, Or does the entire disk need to be defragmented and a bcp out/in would be a waste of time on this table ?I run an index defrag every night, reindex weekly.Thanks.

I use the REORGANIZE option of ALTER INDEX. It's default is ONLINE, no matter what the engine edition and makes for simpler code.
I also make heavy use of my own logging tables, which are included at the bottom of the sp.
Please, feel free to comment. I like getting feedback about my scripts and it seems rarely that happens...

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
SQL 2000We took SQL Server offline last night and defragged the SAN. Should wereindex or will be be okay ?Thanks,Craig
View 2 Replies View RelatedI know the shortcut to 'defragging' the database to eliminate and
reclaim 'whitespace' in data and index pages is to setup a maintenance
plan. This doesn't work for me for two reasons:
1. I like to know how things work.
2. I can not create maintenance plans with my hosted provider.
I use the following T-SQL to rebuild all indexes on all tables:
-- exec sp_MSforeachtable "DBCC DBREINDEX ('?', ' ', 90)
But, does that not only address indexes? What about getting whitepace
back from data in tables themselves?
Am I over-thinking this?
When you're paying for SQL by the MB and generate a lot of data (with a
fair amount of churn) you want to keep it optimized and efficient,
right?
Does anyone know if dbreindex and index defrag ideally perform the same function? I have been told that index defrag does not hold locks on a table when executed and dbreindex does. Other than this is there any difference between the two functions? My understanding was that dbreindex reindexes the data stored in a table for faster reads and index defrag removes purged data. Am I correct? I am currently running both functions on my SQL server and was advised that I really only need to run the index defrag job. Is this advise correct?
View 6 Replies View RelatedI have a clustered index which shows as having a fragmentation level of 66% according to sys.dm_db_index_ physical_ stats.avg_ fragmentation_ in_ percent.
But no matter what I try the fragmentation level doesn't budge. And yes I'm updating the statistics after each attempt.Its not a huge issue the table only has 348 records. I'm testing a fixing fragmentation maintenance script. In Ironing out the syntax of my script I've fixed the fragmentation of indexes of over 65 % anyway..I've come across and index that I can't defragment. I've tried
ALTER INDEX ALL ON [GRIDINFO] REBUILD WITH (FILLFACTOR = 90)
I've tried
ALTER INDEX ALL ON [GRIDINFO] REORGANIZE
I've tried
DBCC INDEXDEFRAG (MYDATABASE, 'GRIDINFO', PK__GRIDINFO__3214EC2721F5FC7F);
The command complete successfully yet the avg_fragmentation_in_percent doesn't change. The table also has a nonclustered index. I've gleaned through all the statements of 'this will have no effect if' but so far I've not spotted a reason why this index won't defrag.The script has been modified to remove schema and database names for the forum.

DBCC SHOWCONTIG ('GRIDINFO')

We have a Windows 2003 R2 server running Sql 2005. Should we stop the sql server engine prior to running the "Defrag" utiltiy that comes with the OS? (Maybe we should also disable the NIC card on that machine too....?)

I am currently re-writing an overnight index defrag procedure and would like to audit indexes in my database - logging the before defrag action" avg fragmentation value and "after defrag action" frag value in an audit table. This will be for all databases on the server. I have completed the vast majority of it (cycling though all the databases, detecting which indexes need reorganising or rebuilding and inserting the information into a table) but I cannot get the audit values working properly. For example, a sample row in my audit table would look like this:
ID Name DB Table frag_before frag_after
1 Index2 DB1 Table6 70.33456 0.03
2 Index7 DB1 Table9 45.98 1.2567etc
On a 2008r2 server, I ran the frag utility against master and msdb and noticed they were severely fragmented.
Is it ok to defrag them using the standard Alter Index command?
We have a new database with cdc enabled on all of its tables. This causes the index maintenance task to fail with following message:
"Executing the query "EXEC DBName.dbo.IndexDefrag_sp" failed with the following error: "The unique index 'PK_TableName' on source table '[dbo].[TableName]' is used by Change Data Capture. To alter or drop the index, you must first disable Change Data Capture on the table. The transaction ended in the trigger. The batch has been aborted.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly" We would like to run the index maintenance without losing the cdc data. We plan on installing SP2 on SQL Server 2008 R2 soon, would that solve the issue? Disabling the cdc prior to index maintenance and then re-enabling back upon completion; would delete the data as I found in most discussions, but we would like to retain it.
What factors would make you decide to use DBCC DBREINDES instead of DBCC DEFRAG when you notice index defragmantation?
Thanks.

My server is a dual AMD x64 2.19 GHz with 8 GB RAM running under Windows Server 2003 Enterprise Edition with service pack 1 installed. We have SQL 2000 32-bit Enterprise installed in the default instance. AWE is enabled using Dynamically configured SQL Server memory with 6215 MB minimum memory and 6656 maximum memory settings.
I have now installed, side-by-side, SQL Server 2005 Enterprise Edition in a separate named instance. Everything is running fine but I believe SQL Server2005 could run faster and need to ensure I am giving it plenty of resources. I realize AWE is not needed with SQL Server 2005 and I have seen suggestions to grant the SQL Server account the 'lock pages in memory' rights. This box only runs the SQL 2000 and SQL 2005 server databases and I would like to ensure, if possible, that each is splitting the available memory equally, at least until we can retire SQL Server 2000 next year. Any suggestions?
Hi,
We have an old machine which holds SQL server 2000 database. We need to migrate a whole database to a new machine which has SQL server 2005.
When we tried to move whole database using Import and Export Wizard, only tables can be selected to import/export. However we want to import/export the whole database, including tables, stored procedure, view, etc. Which tool should we use?
Thanks.

Query analyzer error Unable to connect server local Msg17, level 16,state 1
ODBC SQL server driver [DBNETLIB]SQL server does not exist
Hi,
I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error.
Here is the error:
System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Here is the Environment:
App Server:
Windows Server 2003 Standard Edition
Inside Company's Firewall/ Network
Database Server:
Windows Server 2000 Advanced Edition
SQL Server 2000 SP4
Remote Connections to the Server is checked
Enable Protocols: Named Pipes & TCP/IP
TCP/IP Port: 1402 (I don't know why it isn't the default of 1433)
The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition.
I can ping the db server from the app server using the IP address.
I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server).
I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP?
What do I tell the network admin to change?
Any help would be appreciated.
Thanks,
Oran
