This calls the Sp that does the Reindex. It fails at the update statistics with a very generic message. like " Command: UPDATE STATISTICS [xxxx_DB].[dbo].[xxxx_xxx] [_WA_Sys_00000007_49C3F6B7] [SQ... The step failed."
I suspect it has more error but this is all it is showing me when I right click on the job history. therefore, I updated the job step in the advance tab with log to a txt file. Am I on the right track or there is another way to see error some where else.
I looked at the logs but they didn't show any thing.
We face slow performance issue for like taking long time for same query execution after We apply index rebuild and reorganize index. But, after execution of query or procedure for 2 -3 times, performance will be faster. I have following questions
1 do we need to update stats after we rebuild an reorganize index. 2. is it will be slow for 1-2 times for every query and stored procedure execution after we rebuild and reorganize index?
My SSIS package is running very slow taking so much time to execute, One task is taking 2hr for inserting 100k records, i have disabled unused index still it is taking time.I am rebuilding/Refreshing indexes and stats once in month if i try to execute on daily basis will it improve my SSIS Package performance?
I am using Ola Hallengrens scripts for index and stats maintenance but I am wondering what most people to in terms of the maintenance schedules. At present we do an index rebuild reorg weekly, but do people also do update stats nightly?
I suppose there is an element of "it depends" here in that the data may be fairly static so the update stats may not be required, or if heavily updated then perhaps rebuilding indexes may be required more frequently.
At one of your client sides we have configured Always on with synchronous mode.Also we have schedule rebuild index and update statistics job which runs in night every alternate day. the issue is there are more then 100 sleeping queries which is blocking update statistics job.
I have to stop update statistics job manually once i come to office manually.
Once I have killed blocking sleeping query but then other sleeping query blocked it and so on.
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.
Is it neccessary to schedule a update statistics on index in sql server 2005 on daily basis Is it neccessary to schedule a rebuild index on index in sql server 2005 on daily basis
We use below OLA script to do our index maintenance and one of our previous engineer designed below script on web edition and I have a question of how online index rebuild works when we have web edition. Does the online Index rebuild really works? I am thinking it only reorganizes and does not do online index rebuild.
We have a file import job. This job typically imports millions of records into a SQL2008 DB. After the load the DB performance goes down the drain. Thus far, their solution has been to rebuild indexes on effected tables. I'd like to come up with a better solution. My guess is that after the load, the statistics are shot until the next stats update.
What is the best way to handle this scenario? There must be some way to keep the stats current during a big data load.
When I checked the Properties of the Statistic I can see it is on a varchar(3) field when there are only 3 different values in there - all char(1)
The total size of the data in the table according to the Disk Usage By Top Table Report is 199,680,712KB
So my question is this...
For the UPDATE STATS on this one column with FULL SCAN, does SQL Server read the entire table into the Buffer Pool. If so then if the table had 199,680,712KB of data then why did the session request 145,705,216KB.
Or does SQL Server just read the column and ClusteredIndex Key into the Buffer Pool?
We have a vendor who has an SSIS package that executes a DTS package. We've asked that they migrate the DTS code completely to SSIS, but that is something that will not be done in the near future. The package is scheduled to run every 5 minutes through a SQL Server scheduled job. 95% of the time the package executes without an error, but occassionally the following error is reported.
Date 10/2/2007 7:35:00 AM Log Job History (Pyxis - Data Load)

When I look at the DTS and SSIS package logs no errors are reported and each log indicates the package completed successfully.
Any ideas what this exit code is indicating or how to further troubleshoot the problem?
I have a table that has a primary key that is auto incremented by 1. This table's data is cleared out periodically and as data gets added the auto id primary key continues to increase in numeric value. Once the data is cleared from the table the auto id names could be used again(the eventId is not stored) Currently the eventID is at 26,581,399. I know the maximum int value is 2,147,483,647.
How should I handle this? or rebuild the table every time the data is cleared(problematically)?
Rebuild Index job for user db's is failing, one user db is a huge size 120 GB. The job scheduled to run every sunday 1 AM
I found the below error in log report

I have a table with over 60 million rows (approx 20GB) which has an indexed column. I have tried using DBC DBReindex to rebuild the index, but after kicking it off on a friday, it is still running the following wednesday. Since managers and other finicky types access this database, that's not acceptable (it slows down their reporting).
Is there a way to speed up the reindexing process? Perhaps by adding space to the tempdb (it's 500MB) or putting it in RAM temporarily? I haven't seen any articles that specifically state that TEMPDB is used during an index rebuild, but it seems logical that it would be.
Any suggestions to speed up the process would be most appreciated!
I would like to completely understand the difference between index rebuild Maintenace plan and the customized script.Maintenance Plan rebuilds every single index.It will take the long time as it checks every index.If we use a custom script as a job, it will rebuild the index which has fragmentation >30%.So that, the job will not take much time.
Has anyone noticed a performance improvement during trading hours when they replaced sp_updatestats with UPDATE STATISTICS FULLSCAN in their nightly maintenance? Or is it negligible?
