I am trying to write a sql script that will basically test logins for Windows NT Similar to when you bring up SQL Studio, and do run as windows NT I want to ensure my rights are not removed from SQL Servers and if so send my nice DBA an email.

View 9 Replies View RelatedQuery 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.

I am checking some ratio numbers for our system engineers, those are
Read/write ratio?
Random/sequential ratio?
Read/write block size?
For Read/write ratio, I am using below query,
SELECT
m.type_desc
, CEILING(sum(num_of_bytes_read*1.0) / (sum(num_of_bytes_read*1.0) + sum(num_of_bytes_written*1.0)) * 100) AS 'Read %'
, CAST((sum(v.size_on_disk_bytes) / 1024.0 / 1024 / 1024) AS MONEY) AS 'FileSizeGB'
[Code] ....
Random/sequential ratio, I googled but cannot find a similar query to get the result?
I am writing a performance baseline test.
The first test writes 5000000 rows in one table. I realise this is not representative OLTP behaviour, but it worked me to start interpreting performance counters and to test several setups to be discussed with our server, storage and network administrators. This way we have been able to compare the results of different hard disks, Lun vs vmdk, 1GB vs 10GB network, AMD vs Intel, etc. This way I can also compare several SQL setups (recovery model, max memory config, ...)
The screenshot shows the results of 2 runs on the same server : Win2012R2, SQL2014, 16GB RAM.
In test 1 min/max server memory was set to 9215MB/10751MB
In test 2 min/max server memory was set to 13311MB/14847MB
The script assures the number of bytes inserted in the nvarchar columns is always the same.
This explains why the number of pages and the number of MB in the table are the same at the end of the 2 tests (column 5 and 6)
Since ca 13GB has to be written, the results of test 1 show the lead time is increasing once more than 10GB has been inserted (column 8 and 9) In addition you can see at that moment
- buffer cache hit ratio is decreasing
- page life expectance becomes "terrible"
- free list stall/sec increases
- lazy writes/sec increases
- readlatency increases (write latency does not)
In test 2 (id 3 in column 1 in the screenshot) those counters are not really influenced (since the 5000000 rows can all be stored in memory).
Now what I do not understand is :
Why the number of pages read (instance level) as well as the number of bytes read and the number of reads (databaselevel) is increasing extremely during run 1.
I expected to see serious impact on write behavior, since SQL server is forced to start flushing dirty pages once memory is filled. Well actually you can see here the number of writes (not the the number of bytes written) starts to increase faster in test 1 after 4000000 rows, but there's no real impact on write latency.
Finally I want to notice
- I'm the only user on this machine
- the table has a clustered index on a identity column
- there are no foreign key constraints
- inserts are executed using a loop, not one big transaction
- to monitor progress and behaviour/impact, each 10.000 loops the counters are stored using dmv queries
So I wonder why SQL Server starts to execute so many reads in test 1.
I Want to test for Automatic switch between primary and secondary.
How do i do it ?
or
I need this for some purpose : How to set suspect mode for a database ?
I had an existing table with lots of indexes.
As a test (fro speed) - I added a non clustered column-store index.
When I run test queries it always ignores my new column-store index. Why?
Should I remove the old indexes, leaving just the column store?
We have a reporting database which is refreshed daily from prod backup and later creating new tables/views/indexes as part of the refresh job. Is there a better approach we can implement in sql 2012/2014 for this scenario since we are planning to migrate to sql2014.
View 5 Replies View RelatedHow you would calculate the average read/write latency experienced by a SQL Server instance during a specific time window in order to monitor this for multiple instances. From this MSDN blog, I know that you have to take multiple samples and do some calculations to get the correct latency.
[URL] ...
However, the SQLServer:Resource Pool Stats object tracks these numbers per resource pool and we want to get one number for the whole server. Since there can be a different base value for each resource pool, you can't simply sum the numerator values together. Here's some sample data from a server that illustrates the problem.
object_name counter_name instance_name cntr_value cntr_type
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) default 307318919 1073874176
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base default 25546724 1073939712
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) internal 2045730 1073874176
SQLServer:Resource Pool Stats Avg Disk Read IO (ms) Base internal 208270 1073939712
I'm thinking I would need to do some sort of weighted average, but I'm not sure if that will result in the correct value. Here's the formula I am thinking about using currently before doing the calculation over time
((default * default[base]) + (internal * internal[base]))/(default[base] + internal[base])
Then to do the calculation over time, I'd use the changes in the calculated numerator and denominator to get the average.
Does this sound like to correct way to get this value? Is there a good way to verify?

I am a systems analyst and work with an app that runs against 2 SQL Server DBs. Though I have some familiarity with SQL Server and SQL, I am not a DBA.
The app executable is tied to a Windows service.
When we install the app, we run a process that builds 2 dbs to include:
Tables, indexes, stored procedures, views and user accounts.
SQL Server is set up for mixed mode authentication.
Normally, the dbs run off the local db user accounts which are tied to local logins with the same names.
We have a client that wants to remove our standard logins so that they can run on only a Windows login.
I know I should be able to tie the db users to a Windows login.
And I can do the same for the service.
But I am at a loss as to how to get this done.
How do you associate db users with a Windows login?
When I have tried sp_change_users_login I get an error that the Windows login does not exist. (Though I have added the Windows account to the DB.)
Hope this all makes sense.
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.
I have created a site using VWDExpress and now that I’ve finished testing have moved it over to the server which runs SQLServer 2000. Part of the site requires login, so I created the membership using the ASP.net web configuration tool and when testing locally worked well.
Now though that I’ve copied the web site over, when I try to log in I get the error:
System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified
Obviously its some sort of configuration issue, but I don’t know what.
What do I have to change to make this work from a test machine to a live server?
Thanks

I want to use BCP to load data from a text file.
By default, constraints are turned off in bcp, so I use the CHECK_CONSTRAINTS hint.
bcp aborts if ANY of the rows contains a FK violation. No data get loaded.
So if I add the -b 1 batch size option, it loads all data UNTIL the first FK violation, but nothing after that.
I want to load EVERYTHING ... except for the violations. But bcp won't let me. Is there a way?
If I install an instance with Windows Only authentication, and then change it to Mixed Mode, if I enable the sa login, the password has already been set. What is the default? If it's generated, how secure is it? Is the password generated? What algorithm is used for that?

What is the best approach for a read only copy of a database that is ~ 1TB. The primary database is fed nightly with an ETL process. We are currently trying to duplicate the ETL to read only server but that process is not going well. So we are looking at other options to let SQL make the copy.
The primary database is on a Win12R2 with SQL 12 or 14, a 2 node A/P failover cluster.
The read only copy will be on a Win12R2 with SQL 12 or 14. It is not a requirement to fail over to the read only copy if the primary should go down.
What would best the approach to accomplish the end result?

After installing SSMS on some computers - the only way we can get SSMS to run correctly is to run it as the administrator. Is there a way where you don't have to do that? These end users are logging as themselves and have accounts in SQL Server all set up - but SSMS will only launch for them if we right click and select "run as administrator".After doing some digging - it seems that this is a common problem out there.

View 9 Replies View Relatedwhen execute the restore log command, in the messages window it shows how many seconds the restore takes, at the meantime, on the status bar, it also shows the seconds the command takes.
Two values are different and could be very different, please see below examples , restoring takes 1.8 seconds, but in total the command takes 4 seconds to complete, the other one is 8.1 seconds and 12 seconds.
What does SQL Server or Windows do after the restoring?
pic a:
pic b:
I did a xperf, I can see after the restoring is completed, sql server did garbage collect and log write, which just run very quickly, but storage is busy on reading the log file for nearly 2.2 seconds( 4-1.8), and 4 seconds ( 12-8.1) .
pic 1:
pic 2:
see pic 1 above, from 13 to 17, the restore operation is finished, but the storage jump to 100% active to do some reads, only reads no writes. zoom that period shows pic 2, it read 4096 (I don't know the unit size) for about 4 seconds, what does this do?
Data file, log file, backup file are no different drives, but all local drive, the interesting point is the read jumped after restoring, I tested it on different server, same result...
