We have a maintenance plan that reorganize all indexes in a database. We disabled one of the index on one table this job failed. How to set up to the maintenance plan to without failing to ignore the reorganizing of disabled indexes?

But does Reorganizing Indexes also update statistics?

My production database has a maintenance plan that rebuilds all indexes and it's scheduled to run every day at 5 AM.
I disabled some nonclustered indexes that were not used by any execution plan I found, and run a Profiler session to catch any negative impact in performance.
But I found that the indexes were re-enabled the next day by the Rebuild Index task from the maintenance plan.
Is there a way to keep those index disabled? I don't want to drop them as I could have to re-enable some of them by users' request.
Thanks!
We have our SQL Server 2005 hosted at a datacenter and have only SS Management Studio access (no term serv, no event log, etc.). Also, our hosting company has disabled the Database Mail feature. We have over 60 jobs running on a minute/hourly/daily basis that are critical for our business. It is super important for us to know if and when a job failed.
Given this scenario, how do you suggest we implement monitoring/notification of failed jobs?
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),

This application runs on a SQL Server 2008 R2 database.This application receives messages from an integration module. It has a core table: Table-A. Each message is inserted as 1 row into Table-A. Then when it is processed, that row in Table-A is updated.
There are two environments which are both connected to the same integration. So in both environments, Table-A has exactly the same amount of records inserted and updated. In both environments Table-A has around 80 million rows, with an extra 150,000 rows being inserted and then updated every day.Table-A has 8 indexes. For some reason unknown to me, the 8 indexes fragment really quickly in one environment but not in the other.
e.g. In Environment-1 the index fragmentation ranges from 0 - 19% and this environment has not been re-indexed for over 2 months.BUT a reindex was performed in Environment-2 and only 2 days later the index fragmentation ranges from 72 - 99.93%!
Our DBA has confirmed the re-index in Environment-2 completed successfully and has shown stats before and after the reindex to show that the 8 indexes for Table-A in Environment-2 went down to 0% fragmentation.
My question is, how can the indexes in Environment-2 fragment so much more quickly than the indexes in Environment-1? Both environments are on exactly the same hardware and have exactly the same inbound messages. The database on Environment-1 is actually a clone from Environment-2. The only known differences between the 2 databases is Environment-1 is STANDARD edition - SQL Server 2008 R2 (SP2) whereas Environment-2 is ENTERPRISE edition - SQL Server 2008 R2 (SP1). Could this difference be due to the Service Pack levels or even because one is STANDARD and the other ENTERPRISE?
This is what I have checked so far:
1) In both Environments all 8 indexes have "Set Fill Factor" unchecked and "Automatically recompute statistics", "Use row locks...", "Use page locks..." checked.
2) The "Index Usage Statistics" report in both Environments shows a similar amount of #UserUpdates and #UserScans
I am working with one of the production database around 200 GB. This database has above 350 tables and more than 500 Indexes. I am feeling the database has so many Indexes than the required ones
When I run the below query, it gives me some indexes read value "0". The server was restarted a month ago.Is it ok to remove those indexes?
SELECT OBJECT_NAME(s.[object_id]) AS [Table Name] ,
i.name AS [Index Name] ,
i.index_id ,

user_seeks + user_scans + user_lookups AS [Total Reads] ,
user_updates - ( user_seeks + user_scans + user_lookups )

When creating the snapshot I didn't choose the option copy non-clustered indexes. I created some indexes manually on subscriber database. Replication failed later with some issue.
so reinitialized with new snapshot but all the indexes are gone from the subscriber database.
How to keep the indexes without dropping from subscriber database whenever we reinitialized with snapshot
I written a proc to display the list of Indexes But I needed to print the database where the objects do belong to. How I should write the Dynamic script to add the database Id? I thought to use derived table kind of stuff, but unable to find a solution.

Hi,
I am having a problem with sql server 2005. I would like to access the database but unfortunately I disabled the account I am using to login. Can somebody tell me how can I enable it if possible?
Thanks
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?
Somewhere i read..that in SQL Server...usage of Built-in Functions on Columns, makes query optimizer to ignore indexes on that column...!
So lets say we have table EMP with Emp_id and Emp_Name....
Also we have Non-Clustered index on Emp_Name.
So following query would NOT use Non-Clustered index on Emp_Name column.
SELECTLEFT(emp_name, 3) as emp3
FROMdbo.EMP
Is this true? i am using SQL Server 2008.

I am running SQL 2008 Enterprize Edition with SP1 on Windows 2008. I am trying to set up replication. I have completed the following:
1. Created distribution Database
2. Created publisher

Each time I try to initialize the snapshot, I get the following errors in the SQL Agent Log
1. Log Step.......cannot be run because the LogReader subsystem failed to load. The job has been suspended.
2. Log Step.......cannot be run because the Snapshot subsystem failed to load. The job has been suspended.
I found posts where the records in the msdb.dbo.syssubsystems pointed to different folders than where the dll and exe files are located. So, I checked that, but they are correct.
The SQL Agent has sysadmin on the SQL Server and is using a windows service account.
I believe it is a security issue because I can run the executables from the command prompt to generate the snapshot for the publication. Have I missed the forest for the trees?

I have inherited a server on which is a maintenance plan with two subplans on different schedules. In each subplan there are Execute T-SQL tasks with scripts for index rebuilds. Each task is set up with a Completion arrow to the next task and a Failure arrow to a Notify Operator Task. I was asked to add a task for index rebuilds to a specific subplan for a specific database, which is what the other tasks also do. I discovered that my task was failing but the others were fine. No notification was sent about my task failing even though the job is marked in MSDB as a failed job. I have sent a test email using the "Send Test Email..." option when right clicking Database Mail in SSMSand I receive an email so I know Database Mail works.
I set up a test job to model the index job that I can't get notifications from. I have two T-SQL tasks that just select the top row from a small table. The first task has a syntax error that I did so it would fail. I have a failure arrow to a Notify Operator Task and a Completion arrow to another T-SQL task with no syntax error which has a Success arrow to a Notify Operator task. As expected, when I execute this job I receive one failure email and one success email.
The only other troubleshooting step I know to try is to add a Notify Operator task before my failing task. That Notify Operator task will hopefully fire to tell me that the previous step was successful. I am not having problems with the other steps so I was just thinking I would try to get the subplan to send me a success email about one of the steps that has been working fine.

View 0 Replies View RelatedI have a pretty simple SSIS package that fast loads a 100 million record table into a SQL Server 2008 table on a daily basis. This normally runs fine and completes in about 1 hour. As this is perhaps one of our largest running SSIS packages, about once every 2-3 weeks this SSIS will fail/drop connection. Once it fails, the large number of records will start rolling back. This rollback process can take 1+ hours so I cannot even restart the failed SSIS package immediately. This is a problem.
I am looking for a solution or option so I do not have to wait on that rollback to restart this particular, long running SSIS package. Is there an option/setting to leave the partial data set committed and not rollback? Then I could just restart the SSIS package immediately or set it the SSIS to auto-restart 1 time on failure. The first step in the SSIS does a truncate of the destination table.
Occasionally I'm seeing the following error when tranlog or full backup maintenance plan is executing.
Failed-1073573396) Failed to acquire connection "Local server connection". Connection may not be configured correctly or you may not have the right permissions on this connection.
What is strange is that it goes away without any action from myself. We have a tranlog backup that is scheduled every hour. I had this error happen once in the middle of the night. It looks like the job was running fine because almost all the backups are there. I've searched and not found a resolution to this error. I checked the event log and don't see any issues and even tried rebuilding the maintenance plans.
All the logins with sysadmin role are locked out in one of the SQL server. Also in that instance Logon trigger is implemented which allows only certain users with Windows Authentication to logon.
This server is converted into single user mode by using command prompt. Now we are attempting to connect to SQLServer using command sqlcmd -S FTCPU3239 (since we do not have any other login) and create a new login with sysadmin role but are refused due to logon trigger. it says Login failed for login 'DomainNameUserName' due to trigger execution.
I have a handful of databases that are enabled for Full-Text search. After investigating some recent performance issues, I discovered the FullText Catalogs needed to be reorganized. This is a task I knew I wanted to automate, without having to hard-code db names or catalog names. My first thought was to use sp_executesql with dynamic tsql strings. I was quite disappointed to realize that I couldn't use fully qualified names to run either of these commands:
ALTER FULLTEXT CATALOG [DBName].[SchemaName].[CatalogName] REORGANIZE
ALTER FULLTEXT CATALOG [DBName]..[CatalogName] REORGANIZE
My next thought was to create a stored proc on each user db that would do the re-orgs. Then I could have a sql job iterate through the db's and run the sp on each db. Thinking...Hmm...That's do-able, but I don't like it. Add a new db to the server, and I have to remember to create the sp. Relying on my memory to do something isn't always a good idea. Plus, if I have to fix/edit/enhance the sp, I get the pleasure of doing it multiple times on multiple servers. Too much work.
I came up with some code that would dynamically reorganize all the catalogs, but I had to run it while connected to a specific db. How do I run the code while connected to [master], but in the context of a different db? The undocumented proc [sp_MSforeachdb] came to mind. I'd never used it, and was reluctant to do so after reading about other dba's experiences with it. So I came up with my own derivitive, just for this one purpose. The code is below.
CREATE PROCEDURE dba.ReorganizeFullTextCatalogs
AS
/*
Purpose:
Reorganizes the FullText Catalogs (as needed) on all user databases.
Inputs: None
History:
02/25/2014DMasonCreated
*/
--This is the tsql statement that get executed on each db.
DECLARE @InnerSql NVARCHAR(MAX) =
'DECLARE @Tsql NVARCHAR(MAX)
[Code] ......
I am in a dilemma if I should reorganize or rebuild a full text catalog.
My application owner does not want a rebuild as he says that it takes week for the rebuild to occur on these full text indexes.
Will this code just re-organize without turning off the full text indexes : Alter fulltext catalog catalog_name Reorganize
I have been reworking my index maintenance jobs from my old SQL 2000 table and view references to the DMV's and System Tables in SQL 2005, and I noted that some of my indexes end up being more fragmented after a reorganization and or rebuild. That doesn't make much sense to me at all. The code I am executing is:

If the index begins with PK, then it is the primary key index which is generally the clustered index on the table, but not always. If it has an IX on it, it is generally a non-clustered index on the table, but again not always. In the case of the above, the PK is a clustered index, and the IX is a non-clustered index.
Anyone have any ideas why this is functioning in this manner?
Thanks,
Jon
I'm currently running a reorganize on a large table of ~60 gig. I started the reorganize when I noticed the fragmentation was 97.95%!!!
Well the reorganize has been running for 25 hours now and apparently bulk inserts cannot happen during this time since my SSIS package just bombed trying to prepare for bulk insert.
Anyway, my question is can I cancel this reorg? I didn't start the reorg through the query analyzer. I saw this cute little reorganize button when I right clicked my indexes, properties, fragmentation in the SQL 2005 management studio. I clicked it and then clicked ok.
I know I should have done an alter rebuild but I wasn't comfortable with the process and did the one click solution that is now killing me.
What happens if I go into task manager and shut down the process? Am I risking a serious side effect of corruption or will SQL just stop so I can rebuild the index properly?
why index reorganizing is 10 times slower then rebuild with "ONLINE=ON" clause?

Should I disable IIS on SQL Server 2005? Is there any reason that I should keep it around? I know that it is necessary for reporting services, but our database servers are on a seperate server from our reporting server. We have reporting services running on a stand alone box by itself.
