SQL Server Admin 2014 :: Can Use Different Index On Main DB And Mirror Database

Oct 31, 2015

We use SQL server always on feather on my database and we distribute statement on main database server and mirror database server for raise performance.

My police for split statement is DML (insert, update and delete) statement go to main DB and Read Data (select) statement go to mirror DB.

I want know can I use different index on main DB and mirror Database?

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

SQL Server Admin 2014 :: Deadlock Because Of Non-Cluster Index

Jun 11, 2015

Dead lock is coming in select query in application because of index. It is identified after enabling trace in database and identified by reading deadlock xml file. After index removal, deadlock is not coming in same query. But it is affecting query's performance slightly. Is it correct way to remove index if dead lock is coming because of index?

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,


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?

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 :: Restoring A Database Even If No Database Or Backup Encryption

Sep 3, 2014

I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.

I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1

Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.

SQL Server Admin 2014 :: Logins With No Database Permissions

Nov 3, 2014

Query to show logins that don't have any permissions within the SQL instance? I'm tasked with doing some cleanup and have found some cases where the database was deleted or moved to another server but the logins that used it were not deleted. I'd like to identify them to research.

For instance a query to show logins that have no permissions in any of the existing databases would be handy. I'm thinking it would be complicated by the need to loop through all of the existing databases and then outer join it to the list of instance level logins. Going to try to write something like that but was hoping that a script already exists.

SQL Server Admin 2014 :: Error - Cannot Drop Database Because It Is Currently In Use

Oct 29, 2015

I have an environment with MS-SQL Server 2014 and always-on availability group configured (on 2-nodes).

I'm writing a Powershell Script which removes the database from the availability group (on the primary server) and then SHOULD drop the database on the secondary Server.

That works most of the time, but not always...

When it fails I get the error message:

Cannot drop database "Customer_2" because it is currently in use.

When i check the secondary DB-Server (sp_who2) while the script is running, i see that there is a process for the DB "Customer_2" with Status="background", Command="DB STARTUP" and LastWaitType="REDO_THREAD_PENDING WORK".

As soon as the script fails, this process for "Customer_2" disapears.

This happens always only on the second database in the availability group.

Why is the process still there, even after I removed the database from the Availability Group on the primary node.

If I remove the database from the availability group manually, the "background" process on the secondary node for that database disappears..

SQL Server Admin 2014 :: Copy Resource Database MDF For Upgrading

Feb 11, 2015

Copy mssqlsystemresource.mdf of a recently upgraded server and paste to an old server have same effect of upgrading via .exe installation?

My idea is to save time and administrative efforts in upgrades (Service Packs and/or Cumulative Updates) using this method.

According to BOL:

The Resource database makes upgrading to a new version of SQL Server an easier and faster procedure. In earlier versions of SQL Server, upgrading required dropping and creating system objects. Because the Resource database file contains all system objects, an upgrade is now accomplished simply by copying the single Resource database file to the local server.
