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?

SQL Server Admin 2014 :: Rule Of Thumb For Sizing Log Space During Index Maintenance?

Sep 13, 2014

I've been fixing some issues lately where weekly maintenance has been causing logs to grow and filling disks.

Is there any rule of thumb for allocating log space for doing reorgs and rebuilds in a worst case scenario? I'm thinking 3x the largest database size?

I've been watching them run on databases in the range of 50GB where the logs are growing well over that for rebuilds or even reorgs. Once you have a few databases like this on a server, you can suddenly eat through a lot of disk space just for holding logs during maintenance.

SQL Server Admin 2014 :: Rebuild CMS Tables From XML File?

Jul 23, 2014

I had to reinstall my local copy of SQL a few weeks ago, which naturally overwrote the

msdb.dbo.sysmanagement_shared_server_groups_internal and
msdb.dbo.sysmanagement_shared_registered_servers_internal tables.

However I still have the local XML file that SSMS reads so I can still access the groups, I just get weird errors when trying to re-register my install as the new CMS. How to rebuilt those tables from the XML file or know of a way to repopulate?

SQL Server Admin 2014 :: Log File Size And Log Space Used (Percentage)

Jul 7, 2015

While i execute dbcc sqlperf(logspace); I get following values.

Database NameLog Size (MB)Log Space Used (%)
master 16.17969 13.30275
tempdb 7.429688 61.7245
model 0.7421875 45.78947
msdb 5.554688 25.87904
distribution 2808.93 0.8172179
BANKDB 23438.87 48.20037
WSMIRSDB 109.7422 4.839111

For database BANKDB , Log Space used(%) is 48.83% and Log size is about 23438.87 where as my database size of BANKDB is 60 GB. FULL database and Log back is done every day night one time. My database is performing slow now.

Do we need to take log backup frequently like once a 1 hour so that Log space used will be less. Same query is taking more time to execute than before in same database is it because of log file has increased.

I do index organize and rebuild once a week and stats apply nightly.

Is it correct once log space size is increasing more than 10%. Do we need to take log backup?

SQL Server Admin 2014 :: How To Find Used Space In Memory Optimized Filegroup

Go
select (SUM(size)*8.0)/1024.0 as Space,
FILEGROUP_NAME ( data_space_id ) , type_desc from sys.database_files

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?

SQL Server Admin 2014 :: Reducing Index Fragmentation During Inserts

Apr 26, 2015

We have a database with a table that contains around 180m records. Each day a further 70k are inserted. No records are ever deleted as this table is used for archiving only.Users are required to perform SELECTs on this table constantly but due to the high number of INSERTs the indexes become very fragmented very quickly. My aim is to avoid daily rebuilds of the indexes which is what our software house is telling us we have to do.

This is the DDL for the table:

CREATE TABLE [dbo].[Inventory](
[EAN] [bigint] NOT NULL,
[Day] [smalldatetime] NOT NULL,
[State] [int] NOT NULL,
[Quantity] [int] NULL,
[StockValue] [float] NULL,
CONSTRAINT [PK_Inventory] PRIMARY KEY CLUSTERED

[code]...

There are also three clustered Indexes on this table each referencing a single column. The problem from my side is that I cannot understand why the three columns in a primary key would also be configured as non-clustered indexes.My solution would be one of the following:

1. Accept the tables are going to be fragmented and require a daily rebuild (don't like this one!)

2. Partition the table

3. Remove the non-clustered Indexes and let the clustered index for the primary key do the work.

SQL Server Admin 2014 :: Put A Clustered Index On A Date Column

May 18, 2015

I would like to put a Clustered Index on a date column in a current heap, but one question/concern.This heap every month has thousands of rows deleted and even more added later. How much of an issue will this cause the Clustered Index as far as page splits? I was thinking Fill Factor of 70%.I would normally just test and still will on Dev box, but my Dev box is much smaller than production as far as power.

SQL Server Admin 2014 :: Columnstore Index On Large Tables

Jul 1, 2015

I created columnstore index on the table with 20 columns and about 1000 000 000 rows

every day added about 5M rows

"select" queries became faster because of batch mode and table demand less disk space then before

I have also 6 similar tables with 5 000 000 000 rows and plan to move them on columnstore index

server has 128 G RAM

What pitfalls I could face if I will have so many columnstore indexes on one server?

How a could see problems in DMV?

SQL Server Admin 2014 :: High Availability Index Rebuilds

Jul 9, 2015

I have a situation where I need to rebuild indexes on a large DB (500G).

When I do a test run of the rebuilds in my test environment it uses 100G of space - which is fine with me.

When I do a rebuild in my High Availability environment - same DB, same script - it eats up over 600G of space and fills the volume.

What can I do without removing my DB from H/A to rebuild the indexes?

Because some index are used in mirror DB not used in main database.

Fulltext Index Taking Up All The Disk Space

Mar 27, 2007

I am running a DB with 250Gb of documents, the fulltext index just keeps growing and growing. The files in the MssearchCatalogDir folder is currently taking up 106Gb, it was only 74Gb this morning. The full text catalog size property says its only 53.6Gb and this is remaining steady while the files in the MssearchCatalogDir folder seem to be balloning out of control. I ran a reorg on the fulltext catalog and it did not alter the file space (actually increased it).

There is one *.ci file that is doing most of the growing, its about three times as big as the second biggest one and is expanding before my eyes.

Should I have turned population off when I did the reorg?

Manamgement studio has an Optimize catalog option on the fulltext catalog properties dialog, is this different from a fulltext catalog reorg? Should I run this.

Should I run a shrink file on the filegroup containing the fulltext catalog (the filegroup itself is very small, all the space is in the MssearchCatalogDir folder)?

I have 140Gb left on this drive, is it just going to keep on expanding until I'm out of room, I just dont know what I should do.



Abit more info.....

I was rebuilding the index from scratch (needed to move it to another filegroup).

When I first started the rebuild, msftesql.exe and msftefd.exe were both taking alot of cpu and the overall cpu usage was high. Now after 12 hours, only msftesql.exe is running and is taking up 5-10% cpu. Could it be that the rebuild is not complete yet? Although the Item Count property of the full text catalog does seem to indicate that all documents have been processed, the processes keeps running and disk space keeps going down.

SQL Server Admin 2014 :: Does Security-admin Role Plus Deny Alter Any Login Cancel Each Other Out

Aug 27, 2015

I want to set up a database role so that users can use sp_readerrorlog through SSMS. It does a check on membership in the securityadmin role.

I have tested it and can see you can grant execute on xp_readerrorlog but the SSMS GUI uses sp_readerrorlog.

I thought I could create a user/certificate and add the signature to sp_readerrorlog but it's not permitted (likely because it's not a normal database object).

So the other solution is to add the users to the securityadmin role but then explicitly deny alter any login (best done with a custom server role in 2012+ but otherwise just manually in 2008). I tested this out and it works, I'm not able to alter any logins or increase my own permissions, I also did a check of what's reported from fn_my_permissions(null, null) and it shows minimal permissions like I'd expect.

Server Disk Space Is Getting Close To Full Capacity

Feb 18, 2015

My SQL server disk space is getting close to full capacity which is causing certain reports that we run via the SQL server to time out because I don't think there is enough space on the server.

Any tips on cleaning out a SQL server? Are there any folders that can absolutely be deleted to clear space? I know on a local computer that the %temp% folder can be cleaned out. I know when dealing with servers you do not want to make to many changes because it can cause major problems down the road.

Consistency Issues During/after Disk Rebuild

We had one of the disks in our array fail yesterday morning. The rebuild process using the hot spare went into effect as one would expect. My question is: during this rebuild process, could additional errors be introduced into the database? I'm asking because the current production db has more errors than the restored database from last night.
