Is it a best practice to disable "Allow files on this drive to have contents indexed" on NTFS drives used by SQL for its data, log, tempdb, etc?
In what I've read it seems to be a best practice for Filestream objects and Flash storage drives. We don't currently use Filestream objects or have Flash drives.
Are there any benefits or drawbacks to disabling this feature on an NTFS drive connected to SAN LUNs under mount points?
Hi
I want to know is a flat file faster than a RDBMS for indexing for example a search engine indexing would a flat file be better in terms of performance, scalability etc than a RDBMS?
I have tried doing sql server backups to a file share and that has been taking too long. So I've decided to backup locally and then taking those backups and getting them off the server. For those that are doing this what do you use to get your backups off the server?

View 3 Replies View RelatedI have a CSV File, I am importing this into SQL Server using SSIS package through Flat File source Task.
Few Points about data & its handling
1) inside the Procedure they are dropping the index, then populating the table, then again creating the same index.
2) Data is huge in figure (say, in millions)
My doubt:
which is the best way to import the data
1) Just inserting the data without dropping the Index
2) Drop index, populate table, re-create index (the way they do right now)
I've created a table which will hold staffing data (name, grade, etc.) and any shifts that are going to be entered. I've got some test data in the table.
The base table looks like this:-
CREATE TABLE [dbo].[tbl_ForecastShifts_New](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Ward] [nvarchar](255) NULL,
[StaffBand] [real] NULL,
[StaffMemberName] [nvarchar](255) NULL,
[Code] ....
I've attached a spreadsheet with the test data from the table and the required layout on the second tab.
I've created a view which displays the data as I want it and I need to attach this to an MS Access front-end for the users to input/edit the data in the table with the use of a Access form.
The view I've created looks like this:-
CREATE view [dbo].[vw_Forecast_Staffing] with schemabinding
as
select
s.Ward
,s.StaffBand
,s.StaffName
,d1.Date1
[Code] ....
It displays all the staff members and any shifts they've been given for a 7-day period with day 1 begin supplied by the user.
The user will also supply the ward they are interested in viewing.
When I attached the view to Access it becomes read-only as it doesn't have any indexes on it.
I can't create a clustered index on the view as there are derived tables.

View 6 Replies View RelatedIt's often said or done that when inserting or updating into a 'large' table that disabling the non-clustered indexes can is needed for performance.
Now I know the obvious way to find out if this is best or not is by testing the different options. I was wondering if there was a rule of thumb to this?
Say you have a table with half a billion rows and 4 non-clustered indexes and are only updating half a million rows then sometimes disabling every night and re-enabling can take way more time than the actual update. Haven't found an articles advising to disable them when a table is over X rows and you are updating Y% of them...
Disable logins on access expiry date(Not windows password expiry). we grant access to users on databases only for 60 days. So access is only valid for 60 days. Then the user should again request access to the database going thru security clearance. Thn the DBA's enable the login. Maintaining all these logins of users manually is causing more confusion.
As we know, we dont have any inbuilt functionality to automatically disable logins in SQL Server.
I have a table where the logins and expirydate were recorded in a DB.
Using this table and SQL Server agent. Can i achieve this process automated ?

Hi,
I want to migrate from Oracle to SQL Server 2005 but I have a problem:
I want to use fulltext on external files as doc,xls,txt,pdf,etc without uploading them into a BLOB field as with oracle ultra search. How can I do?
Thanks
When I restart the server that hosts the database engine SQL Server 2005 Standard Edition SP4, the trace gets up mytrace-5.trc with a size of 100 MB and id is 2, leaving the hard disk space, then the SQL Server stops execution of the trace due to lack of space. I do not know how to erase the trace, because I do not know where is it.
The archive log looks like : SQL Trace ID 2 was started by login "sa"
Trace ID '2' was stopped because of an error. Cause: 0x80070070(There is not enough space on the disk.). Restart the trace after correcting the problem.
I only know how delete a trace, knowing id.
EXEC sp_trace_setstatus 2, 0
EXEC sp_trace_setstatus 2, 2
Which configuration file I can disable all SQL Server traces. If I run select * from sys.traces, I just get the default trace:
id = 1
status = 1
path= D:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLLOGlog_32736.trc
max_size = 20
stop_time = NULL
max_files = 5
is_rowset = 0
is_rollover = 1

I have 2 dbs (SQL 2012) - one contains a trigger that is enabled/disabled by a procedure in the other database. This all works fine.
If I create a Database Project solution in Visual Studio 2012 SSDT (or 2013) for both databases, the stored procedure generates a SQL71502 stating that my trigger name can't be resolved.
To recreate the issue:
CREATE DATABASE DbWithTrigger
GO
USE DbWithTrigger
GO
CREATE TABLE dbo.TblWithTrigger(
Id int NULL,
SomeValue varchar(30) NULL
[code]....
-- Test to confirm
EXEC CrossDbTriggerCall
INSERT DbWithTrigger.dbo.TblWithTrigger VALUES(1, 'Blah blah')
In Visual Studio 2012:
1. Create a new solution with a project named DbWithTrigger
2. In project settings set the Target platform to SQL 2012
2. Import the DbWithTrigger db into this project
3. Create a new project named DbCallsTrigger
4. In project settings set the Target platform to SQL 2012
5. Import the DbCallsTrigger db into this project
6. Add a Database Reference in DbCallsTrigger for DbWithTrigger
When you build the solution both dbs build successfully, however there are two warnings. One is easily resolved by replacing DbWithTrigger in the body of the procedure with [$(DbWithTrigger)] (db variable name for the reference) but I can't find out how to get rid of the other. Is it a bug?
Hi,
I am having difficulty in indexing a Table when it contains a PDF file in an Image column. Basically I have a table with a unique id, some other fields, and an Image column. The Image column contains uploaded files from a web application. Full-text indexing works fine for all types of files that I have uploaded into this table which includes (.doc, .xls, .ppt) but I get the following message in my Event Viewer if one of thee files is a PDF file.
One or more documents stored in the Image columns with extension '.pdf' did not get full-text indexed because loading the filter failed with error '1x01'.
I have searched Microsoft's site and implemented their prescribed fixes but none has worked including installation of SP3 of Sql Server and/or modifying the registry key to run the Sql server indexing procedure as a single threaded process.
Has anyone experienced this problem? Please help.
Thanks
Kamal

Can we disable a flat file connection manager in a ssis package just as how we can disable a OLE db task? When I try to disable the flat file by clicking on work offline its gets disabled which is what i expected , but when i close the package and reopen it again its again enabled , is this the way that a flat file connection manager works.

The TEMPDB transaction log file keeps growing.The database server is new and the transaction log was presized to 1 GB on installation. After installing a number of databases, the log file grew over a day to 38GB. Issuing a manual checkpoint was the only way to free some space to allow it to be shrunk back to a usable size. The usage of the file is still going up.
I am struggling to find what process is causing the log to be used so heavily. Looking at the log reuse wait desc for tempdb returns "Nothing" and tempdb itself isn't being used very much or growing in size.
I have a filetable that contains a binary file. I need to do a selective read of the file stored in the file table. I can write a C# CLR function that will open the file, read n bytes the from a starting byte. Or I can write a SQL statement that reads the stream in the filetable into a VARBINARY variable using SUBSTRING beginning at the starting byte (offset from 1) for the same n bytes.
Both give me the same result. However, the SQL statement takes considerably longer to read. I know there is overhead in reading through SQL (interpreted language), but the difference in performance is substantial, and I can only attribute this performance degradation if SQL first tries to "load" the entire stream before it identifies the portion of the stream that it needs to read beginning at the starting byte offset.
I wonder if this is the case or if there is another option to read a stream from a filetable directly through SQL queries that is more efficient.
Why shrinkfile empty file does not redistribute data evenly in the primary file group with multiple files:
Please run the script attached to see what the end result is.
This is what I set up last night on my test machine.
1) Create database [FGTest] size 200MB
2) Create table called TEST on primary
3) Insert 40MB of data into test
4) Create another file group called temp in primary size 200MB
5) Shrinkfile('FGTest',emptyfile) so that all data is transfered from FGTest into temp file group.
6) Add another 2 files called DATA2 and DATA3. Both are 200MB.
7) We now have 3 empty files that I want data distributed evenly on. FGTest, DATA2 & DATA3
8) Shrinkfile('temp',emptyfile) to move all the data from temp over the 3 file groups evenly
I would expect at this stage to have the following:
FGTest = 13MB,
DATA2 = 13MB,
DATA3 = 13MB
(40MB of data over 3 files should be about 13 MBish in each file)
What I actually end up with is this:
FGTest = 20MB
DATA1 = 10MB
DATA2 = 10MB
It looks as though SQL Server is allocating 50% of all data to the original file and then 50% evenly over
the remaining files in PRIMARY.
We have a large 'History' database that is currently about 4.5TB, with most of that in a datafile that is 4.2TB. We wanted to stop growth on the one large data file and have SQL Server allocate new data to the other data files, but this throws an error when we attempt to change the MAXSIZE settings:
ALTER failed for Database 'History'
MODIFY FILE failed. Specified size is less than or equal to current size.
The SQL Server is saying we can have a max size of 2TB, and anything over that is blocked. Since this is being blocked, the file continues to grow.
Is there any way to cap the growth of the 4.2TB file and not allow any more data to be written to it?
is there limitation for size of file to store in db by filestream in sql server 2008?or it accept all sizes?

View 3 Replies View RelatedSo i'm not really new, but got a question. i've recently been looking to to the Western Digital Raptor Drives.
as far as performance, it's always been my understanding that the speed of the hard drive is just about always the bottle-neck of a computer. i'm currently running 2 stripped WD 500gb SATA drives for my SQL server (dual Xeon 2.8 with 2GB memory).
i'm thinking of upgarding to 4 WD Raptors (10k RPM) drives, the new 150GB models. anyone have an opionion? do you think i'll get a large performance increase?
the database that i run queries off of now is about 125 Million names, with about 80 fields in width. so it's rather large, and usally takes a fair abount of time to get my results back (we're talking anywhere from a minute, to half the day.)
do you think the raptors will slim that down significantly?
We recently installed SQL Server 2005. The server has 3 drives. When I try to restore a database I can only access the C: drive. How do I make the D: and E: drives visible in the "locate folder" window?
