SQL 2012 :: Maintenance Plan - Rebuild Indexes Only Run If Required Or Open Fires On Schedule?
Aug 23, 2015
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 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] ....

Under the maintenance plan, i run full backup at the same path and it was successful. The maintenance plan for selected database was run success.
BUT when i want to write the backup report "Write a report to a text file" i receive this error in maintenance plan "view history"
Access to the path 'F:MSSQL11.APPSPRDMSSQLBackupBackup LogCARSCARS DB Backup_Subplan_1_20140701200011.txt' is denied.
Basically i am using defaul NT service for SQL Agent

Server: SQL Server 2012 Enterprise 64bit
I created a maintenance plan with full user database backups, backup files cleanup, and database shrink.
I did it in SSMS and it also created "Reporting Task for subplan-{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}".
It works fine in the development server where I created the plan. I imported the same into other environments test, stage, and prod. I did use BIDS to change the connection string manual "Local server connection". The job runs fine in other environments but it fails at the end where the "Reporting Task for subplan" is executed. I looked at the dtsx file codes and I could not find anything wrong.
It seems to be a bug at the Microsoft side.

Our backups by default go to a network location, but I'd like to modify our maintenance plans to backup to an alternative location if the primary location isn't available. I've setup two Backup Database Tasks where the second one runs only if the first one Fails, and if the second one runs (on first one's failure) it then sends a notification to me so I know this occurred.
The Plan is running as expected, when I simulate a bad path in the first Backup Task the second one runs and the notification is sent, but the Job shows failure. I'd like to show the job as Successful when this occurs since I'm handling the issue and notification within the Plan, but I'm unable to find out how. I've set FailParentOnFailure to False on the Plan and I've changed the MaximumErrorCount to 2 with the assumption that this would work, but neither didn't.
Also I'm running into this in both SQL 2008 and SQL 2012.

I have a scenario where i have to run update task on multiple servers in parallel and once all of them are completed (success or failure) another task is to be run on another server
1. in maintenance plan, if we add tasks which are not joined, will they run in paralled at the same time
2. if we link the last task to all the tasks with link type 'completed' will the last task complete after all tasks are completed or when any one of them is completed (i have big doubt here)
the business requirement behind this is to bring data from multiple servers into shadow copies locally and then process them together. its ok if some server data transfer fails, but its not ok to start processing centrally while data transfer is going on. further, we want to run data transfer from multiple servers in paralleled to save time.

Hello,
I have a question that I hope someone can clear up for me. I have come across a number of different suggestions on DB maintenance, for example reindexing with the following script:
USE DatabaseName --Enter the name of the database you want to reindex
DECLARE @TableName varchar(255)
DECLARE TableCursor CURSOR FOR
SELECT table_name FROM information_schema.tables
WHERE table_type = 'base table'
OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
DBCC DBREINDEX(@TableName,' ',90)
FETCH NEXT FROM TableCursor INTO @TableName
END
CLOSE TableCursor
DEALLOCATE TableCursor
My question is, doesn't the maintenance plan have this functionality inherent in it when you create the maintenance jobs to reindex? Is there a benefit to scripting things out vs just using the maintenance plan wizard for this sort of thing and any of the items it covers? I came from an Oracle background where this was a no-brainer but I am a bit confused on the choices with SQL Server.
Thanks.

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,

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.

Rebuild index maintenance plan is failed, since we don't have space in the C:Drive we have left the option as it is to sort the results in user databases respectively. These user databases are in E: with sufficient space to rebuild index.
Check the below details.
SQL Server 2005: Microsoft SQL Server 2005 - 9.00.5000.00 (X64) Dec 10 2010 10:38:40 Copyright (c) 1988-2005 Microsoft Corporation Standard Edition (64-bit) on Windows NT 5.2 (Build 3790: Service Pack 2)
Online reindexing supports in SQL Server 2005 Standard Edition? Job is failing because these options (sort results in tempdb & keep index online while reindexing) is not checked (enabled)?

I'm upgrading to SQL 2012 from 2008R2, while doing so i will be rebuilding all the indexes on all the database. In my previous environment while doing so, i got space related error in primary filegroup for insufficient space in the primary filegroup. Is there any rule of thumb about how much space is required by index rebuild command for each database, or is there a safe threshold for free space in the database?

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.

hi all
i am under impression that indexes also stored seperately from data and need extra space . when we check in EM Table Info, size over there is just data size or sum of data and indexes. if it is just for data then is there is any space used to store indexes and that space is counted in space used by data base or else where.............. please clear my confusion.............. i am quite new in administartion of SQL Server

Hello All
I have been given a SQL Server 2000 database to look after which has been set up with a Database maintenance plan. The plan is set to backup the complete database and the transaction log. The backups are written to the local disk correctly but the plan is also set to remove any backup files (both database .BAK and transaction log .TRN) that are over one week old. Complete database .BAK files are written daily and the .TRN are written every hour daily. The .BAK files are removed ok automatically but the .TRN files are not - they are just slowly filling the disk. There does not seen to be anything different between the way the main database and the transaction log is set up in the maintenance plan.
I would be very grateful for any ideas

I have a strange thing in one of our Maintenance plans.
On the first tab where you check which databases you're including in the plan I have (say my database name is CAT) a 'CAT' and 'cat' database listed and the one chosen is 'cat'. However my database in all other views shows up in all caps. (even when I do an sp_helpdb)
The backups look like they're working, etc. but it just seems weird. If I go to create a new plan it only gives me the one option 'CAT' which is really what's there. I'm new and I'm thinking the database at one time was 'cat' and this is when the maintenance plan was created. Then it was renamed to 'CAT' and there's the two db's showing in the old mainenance plan.
What would you do? Create a new plan with "CAT" and just get rid of the old one with the weird 'cat' and 'CAT'?
Any other suggestions or ideas on what happened..

hi everyone..
this is a little bit weird ..
i am trying to make a backup strategy. i am using sql2005.
when i go to maintenance plan. right click >> new maintenance plan...
nothing happens..
if i go with the maintenance plan wizard everything goes normally.
after doing the backup, if i right click on it and press
modify , nothing happens too.
what i mean by nothing happens is that it doesn't open the "design view".
the back up is doing normally.. but i need to set a range of 5 days before overwriting the oldest backup.
any idea what is going on or what am i missing?!
thank you

Windows Server 2003R2 w/ Sp2
SQL 2005 w/ Sp2
Created weekly (full backup) and a daily (differential backup) Maintenance Plans using the wizard. I formatted the server, installed the OS and SQL. Restored the full backup (No Recovery Mode), then restored the differential backup (Recovery Mode), tested and all worked well.
Then I noticed the original Maintenace Plans I created (Full and Differential) were gone; makes sense as I had formatted the server.
Is there a way to create a Maintenance Plan file or script that I can save and just add back to the server??
Hope that makes sense.
Any help appreciated.
