Change sql server database mode from full to simple when others access that database. What could happen?

That' sql server 2008.
Thanks

Hi,
As I understand, you're basically interesting in the situation where users are connected to the database and they are using the database at the time you change the database recovery mode. It is highly recommended not to change the recovery mode while users
are using the database, especially do not use any bulk operation!
1. I highly recommend to read this link:
View or Change the Recovery Model of a Database (SQL Server)
http://technet.microsoft.com/en-us/library/ms189272.aspx
2. as mentioned by all previews post there is several consideration that you should know regarding the database itself during the operation, as (1) logs are truncated, (2) process breaks the log chain, and loose point in time recovery.

After sql server 2012 installation, I have changed sql server database engine service account from network service user to system user. What is disadvantages of this process?

     After
sql server 2012 installation, I   attached my production db. Because of some reasons, i
changed sql engine account from network service user to system user by means of sql server configuration manager.
     Now , there isn’t
a problem at sql server running system. But
I have doubts that
this can produce problems later. Because sql server database engine account must have privileges that listed below;
Log on as a service (SeServiceLogonRight)
Replace a process-level token (SeAssignPrimaryTokenPrivilege)
Bypass traverse checking (SeChangeNotifyPrivilege)
Adjust memory quotas for a process
(SeIncreaseQuotaPrivilege)
Permission to start SQL Writer
Permission to read the Event Log service
Permission to read the Remote Procedure Call service
While sql server installation, setup gives these
privileges to network service user automatically, but changing user by means of sql confugarition manager does not give these
privileges.
Now, system user has privileges listed below. And sql server has been running for 1,5 months without any problems.
Log on as a service (SeServiceLogonRight)
     Bypass traverse checking
(SeChangeNotifyPrivilege) (Everyone user has his privileges. So i think that system user has this privilege also)
What problems can occur because of this situation? Shall i give other privileges to system user and restart sql server or not? And how can i give these privileges to system user listed below;
Replace a process-level token (
this can be set from user rights assignments)
Adjust memory quotas for a process
(this can be set from user rights assignments)
Permission to start SQL Writer (
? - give advice )
Permission to read the Event Log service (
? - give advice )
Permission to read the Remote Procedure Call service (
? - give advice )

Our server is windows server 2008 r2 enterprise edition. I have looked the bunch of permissions in user rights menu that is in local security policy settings gui.
And i have seen those permissions below were not granted to system user;
Bypass traverse checking (SeChangeNotifyPrivilege)
Adjust memory quotas for a process
(SeIncreaseQuotaPrivilege)
So, briefly you say, don't panic ?

CR-11.5/ODBC-Changing SQL-Server Database in same instance

I'm using CR 11.5 against SQL-Server 2005. In the same SQL-Server default instance, I have both Demo and Production databases. I've used both the SQL-Server Native ODBC driver, and the OLE/ADO driver as a trial. Some of my reports have used the standard Table selection method to generate the SQL; others have needed a Command script due to embedded subqueries.
My problem is getting a Demo reports changed over to Production reports. If I make up an original Demo ODBC connection against the Demo database, and then make up a new Production ODBC connection against the same instance but against the Production database, the Data Source will change over to the newly named ODBC connection, but the Database remains pointed at the previous Demo database despite the new ODBC connection telling it to do otherwise.
This seems particularly troublesome with the standard Table reports as the the new connection Database properties have to be changed to Production as well as the Database properties for every single table.
Also, is it possible to use just one ODBC connection and force the change by changing the default database from Demo to Production and updating the data?
Am I missing something here?
Thanks!

Recover SQL Server database from SUSPECT mode

Hi Expert DBAs,
As I know the database should be restored from backup and logs reapplied. That’s the first and generally recommended approach any time a DB is suspect, whether it’s from log or data file corruption.
But if I have no backups then we follow below steps ( after Googling I found these steps on most of the websites ):
1.EXEC sp_resetstatus ‘yourDBname’;
2.ALTER DATABASE yourDBname SET EMERGENCY
3.DBCC checkdb(’yourDBname’)
4.ALTER DATABASE yourDBname SET SINGLE_USER WITH ROLLBACK IMMEDIATE
5.DBCC CheckDB (’yourDBname’, REPAIR_ALLOW_DATA_LOSS)
6.ALTER DATABASE yourDBname SET MULTI_USER
Now my question is,
1. If after executing DBCC CHECKDB at 3rd step, it shows inconsistency.Then I will execute SET SINGLE USER WITH ROLLBACK & if after executing DBCC CHECKDB at 3rd step, no errors found. Then what will be the steps?
2. When we execute DBCC CHECKDB (' DBNAME ', REPAIR_ALLOW_DATA_LOSS) how can we recover lost data during process.As far as I know some data will loss and if it will happen then business will get suffered.
3. Why run DBCC CHECKDB() WITH REPAIR_ALLOW_DATA_LOSS if there are no consistency errors in the database?
I am stucked in these questions....

Yashwant Vishwakarma | SQLOcean.com

There is no easy or same steps, it all depends on what error and what caused suspect.
Example is below:
http://www.sql-server-performance.com/2015/recovery-sql-server-suspect-mode/
2) Straight answer would be no you cant recover if no backup. Again it all depends what error checkdb returns and some things can be tried as explained earlier but no guarantee.
The REPAIR_ALLOW_DATA_LOSS option is not the best option for bringing a database to a physically consistent state. If successful, the REPAIR_ALLOW_DATA_LOSS option may result in some data loss. In fact, it may result in more data lost than if a user were to
restore the database from the last known good backup. Microsoft always recommends a user restore from the last known good backup as the primary method to recover from errors reported by DBCC CHECKDB. The REPAIR_ALLOW_DATA_LOSS option is not an alternative
for restoring from a known good backup. It is an emergency “last resort” option recommended for use only if restoring from a backup is not possible.
Certain errors, that can only be repaired using the REPAIR_ALLOW_DATA_LOSS option, may involve deallocating a row, page, or series of pages to clear the errors. Any deallocated data is no longer accessible or recoverable for the user, and the exact contents
of the deallocated data cannot be determined. Therefore, referential integrity may not be accurate after any rows or pages are deallocated because foreign key constraints are not checked or maintained as part of this repair operation. The user must inspect
the referential integrity of their database (using DBCC CHECKCONSTRAINTS) after using the REPAIR_ALLOW_DATA_LOSS option.

Is it possible to have different authentication mode for SQL Server Database Engine and corresponding SQL Server instance?

Hi,
I have installed the x64 SQL Server 2008 R2 Express with default settings and run MBSA 2.3 (using default settings too). It shows three SQL Server instances: MSSQL10_50.SQLEXPRESS, SQLEXPRESS and SQLEXPRESS (32-bit). For the first, authentication
mode is Windows, for the rest two - mixed. Here https://social.msdn.microsoft.com/Forums/sqlserver/en-US/03e470dc-874d-476d-849b-c805acf5b24d/sql-mbsa-question-on-folder-permission?forum=sqlsecurity question
about such multiple instances was asked and the answer is that "MSSQL10.TEST_DB
is the instance ID for the SQL Server Database Engine of the instance, TEST_DB", so in my case, it seems that MSSQL10_50.SQLEXPRESS is the instance ID for SQL Server Database Engine of the SQLEXPRESS instance.
I have two questions:
1) How can it be that SQL Server DB Engine instance has different authentication mode than corresponding SQL Server Instance?
2) Why 32-bit instance reported although I installed only 64-bit version?
Also, this https://social.technet.microsoft.com/Forums/security/en-US/6b12c019-eaf0-402c-ab40-51d31dce968f/mbsa-23-reporting-sql-32bt-instance-is-running-in-mixed-mode-when-it-is-set-to-integrated?forum=MBSA question seems to be related to this
issue, but there is no answer :(.
Upd: Tried on clean Windows 8 installation and Windows 7 with the same result.

Because I DO NOT want the three people who will be having access to the production SQL Server to also have access to the primary host ProductionA. Since I have to allow them to RDC into the box to manage the SQL Server, I figure why not create
a separate VM for each one of them and they can RDC into those instead.
Does this make any sense?
Any tips are greatly appreciated. The main reason for doing this is because the three people who will be accessing the box, I need to isolate each one of them and at the same time keep them off of the primary ProductionA.
Thanks for your help.
M
Hello M,
Since you dont want the 3 guys to have access to Production machine A.You can install SQL Server client .By client i mean SQL server management studio(SSMS) on there local desktop and then create login for them in SQL Server.Open port on which your SQL server
is running for three of the machines so that they can connct.Now with SSMS installed on each machine each can connect to SQL server from there own machine.
I would also like you to be cautious with giving Sysadmin privilege to all three of them ,first please note down what task they would do and then decide what rights to be provided.
Your option will also work but you need to create 3 VM for that .Which is more tedious task.
Hope this helps

Full Database Backup in DB13 for MS SQL Server databases

Hello,
We have some SAP systems using the MS SQL Server database. I want to know if it is possible to setup the Full Database Backup option in transaction DB13 to store the files in a hard disk space.
I already did this type of configuration in SAP systems in Oracle databases and for this I used the init<SID>.sap where we can put all the configuration, for instance the disk path where we want to save the backup files! But for MS SQL Server databases, in DB13, I don´t know how to do that, when I add the "Full Database Backup" option in DB13, this show me some options but only for tape, but I don´t want to store the backup files in tapes, I want to store/save the files on the server disk itself or else to an external disk but I don´t see where I can set this way of storage!
This is what you see in DB13 (when using a MS SQL Server database) in "Full Database Backup" and as you see I only have options for TAPE not for a disk or other type of storage! How can I do that? (if that is possible):
Can you help me please?
Kind regards,
samid raif

Hello Raja
Sorry for the delay of my answer! Many thanks for that tip, it helps a lot and it solve the last error/problem that I reported here, in fact, the problem was we had named the device with two words containing a space. So we removed that space from the backup device (in SQL management studio) with one word only and the job runs successfully without any errors!
It works in Development and Quality systems but in our Production system (AM1) the Full backup option in DB13 stopped with the following error, in fact the error is on verification of backup, it means that the Full backup finished with success, but when it does the backup verification, the job in DB13 stops with an error, the following one:

SharePoint 2013 - Server Error in '/' Application - This operation can be performed only on a computer that is joined to a server farm by users who have permissions in SQL Server to read from the configuration database

Hi
After I ran SharePoint configuration wizard successfully to upgrade to SharePoint 2013 / SP1.
I can open Central Administration site just fine.
but now when I open any Site collection, I got this error.
Server Error in '/' Application
This operation can be performed only on a computer that is joined to a server farm by users who have permissions in SQL Server to read from the configuration database. To connect this server to the server farm, use the SharePoint Products Configuration
Wizard, located on the Start menu in Microsoft SharePoint 2010 Products
I have restarted all the servers: SQL server, WFE and APP servers but still cann't get this resolve.
Services on all servers are running, IIS - application pools are running.
Can someone help with where that could be a problem or if there is a solution.
Thanks in advance for your comments or advices.
Swanl

Please verify the followings:
Make sure that from the SharePoint front end and application servers that you can ping your SQL server.
Make sure that your Farm account has permission to the configuration database.
Lastly verify that your database didn't for some reasons go into recovery mode.
once everything is fine and you are still having issues, restart the SQL host service on the SQL server.
Once the service is restarted you will need to reboot Central Admin and then your front end servers.
In addition, as you built your farm inside the firewall, please disable the firwall, or create rules for SQL Server service in the firwall on SQL server.
More information about creating rules in firewall, please refer to the following posts: http://social.technet.microsoft.com/Forums/en-US/c5d4d0d0-9a3b-4431-8150-17ccfbc6fb82/can-not-create-data-source-to-an-sql-server http://www.mssqltips.com/sqlservertip/1929/configure-windows-firewall-to-work-with-sql-server/

How can I get the data array from SQL Server Database?

Hi,
I can write a data array(2D)into a table of my SQL Server Database. The data array was writen to a column with image type. I know a data array is transformed a binary string when writing into database, but I dont know how to get the data array when I fetch the binary string from database.
My question is:
How to transform the binary string into data array? which vi's should I use? I have tried unflatten from string but failed.
Any response is appriciated.

In order to use Unflatten from string you first need to Flatten it
before writing it. Also depending on the database driver, the returned
data may actually not be binary but Hexadecimal encoded ASCII which you
would first have to decode to binray.

How to create a .mdf SQL Server database from a Data-Tier Application file that has data?

This is a noob question, though I do use SQL Server databases all the time with Entity Framework when I code in C# using Visual Studio 2013. The development environment is found below at [A]. I am trying to make a clone of a SQL Server 2008 R2
database (.mdf) that exists online. I can read, connect and work with this database in Visual Studio 2013, but I wish to make a local copy of the database, as an .MDF file. Somewhere in my notes I have a way of creating a local copy from
an online database when using Visual Studio but I forgot how (it seems, reviewing my notes, that it deals with ADO.NET which is deprecated in Visual Studio 2013 these days, or so it seems). So I'm looking for another way. What I did was create
(or export) a "Data-Tier Application File" from the online SQL Server database, with data, and it seems to have worked in that this Data-Tier Application file exists on my hard drive and seems to have data in it ("SQL Server Replication Snapshot"
is the format it seems). It contains skeleton code to create a database, but when I tried to execute it with SQL Server 2014 Management Studio, I got a bunch of errors.
So my question is:
1) Can I somehow create a .MDF SQL Server Database from an Data-Tier Application file that has data? What tool do I use? I saw this link, http://social.technet.microsoft.com/wiki/contents/articles/2639.how-to-use-data-tier-application-import-and-export-with-a-windows-azure-sql-database.aspx
and it relates to Azure, but is there a tool for C#Visual Studio 2013, standalone?
2) If there's an easy way to create a .mdf SQL Server Database file from an online file, within SQL Server Management Studio? I don't think so, since it would require Administrator permissions on the online server, which I don't have. I have permission
to read, update, delete the online database file, but strangely not to download it (the service I use has a tool for backup, but not for download).
3) same question as 2), but for Visual Studio 2013? I don't think so, since I notice none of the templates even mentions ADO.NET anymore, but instead they go with Entity Framework. Using EF I can of course do anything I want with the online database
(CRUD), but it remains online. Maybe there's a switch to make a local copy? I guess I could write a short program to suck all the data out of the online database and put it into a new, duplicate database having the same tables, that I create on
my localhost, but my question here is if there's an easier way than this, maybe a tool or command I can run from inside Visual Studio?
Any advice on any of the above questions is appreciated.
Thank you,

JAVA, sqlserver - Need to load an image from the sql server database

hi,
I need to load an image from the sql server database using java. I have connected to the database and getting all other records except the records for a photo (datatype = LONGVARBINARY) and Remarks (datatype = LONGVARCHAR).
I am using java and sql server db. The photo and remarks are stored in the db. and i need to show the image and the remarks fetching them from there.
I get the error :
Thread-9 org.hibernate.MappingException: No Dialect mapping for JDBC type: -1
How can I achieve this?
Thanks,

Exactly. And are you using MySQL?
No. You are using Microsoft SQL server if I have to believe your initial post. A quick google tells me that the dialect class to use is:
org.hibernate.dialect.SQLServerDialect

SQL Server database (read-only mode) in Oracle SQL Developer

Hello,
I connected SQL server database with Oracle SQL Developer 3.2.10.09, everything looks good except i can only browse data, i cannot change data in tables cannot insert new or delete rows. Query is also disabled (i got message: Query Builder is not supported for this connection type.) I used Third Party JDBC Drivers - jtds-1.2.6.jar as my connection to SQL server. Is there a way to change data in tables?
Thank you.

AFAIK editing table data in the grid is only possible with an Oracle database. On MS SQL you'll have to use update statements in the worksheet.
Hope that helps,
