Hi all,
I've a database with memory optimized objects, last night the log become full due to insuffcient space on the hard disk. I have added free space to the volume where log files is, databases are working now but I noticed that the database with memory optimized objects uses 30GB of log space (datafiles is 60GB) and if I run a
select log_reuse_wait_desc* from sys.databases where name='MyDatabase'
I get
XTP_CHECKPOINT
what is going on?
How to free space on this database log?
I am using PowerShell 4.0 on a laptop with Windows 8.1 Professional.
I have a named instance of SQL Server 2012 named 'RegencyPark' on my Toshiba Laptop named 'Hodentek8'
I can connect to the instance (Windows Authentication) and browse the nodes, run queries, etc.
I launch Powershell from SSMS using a data context. I can very much browse the SQL Server using SQLPS.
However, when I try to run a query I get the named pipe error that the connection could not be made.
---------------------------------------------
I start PowerShell from start and provide the connection string to connect to SQL Server. I can establish the connection, create a new database etc. However if I try to run a select query, I get the same named pipes error.
I check the procols and verify I have enabled Named Pipes. The SQL Server Browser is working.
I am not sure if it has anything to do with the innumerable windows update that is flooding the computer.
I have documented in detail these here:

http://hodentekmsss.blogspot.com/2015/06/powershell-cannot-connect-to-sql-server.html
There may be ambiguity in how the installation program of SQL Server retrieves the Windows User as seen in the next two posts. I wonder whether the names pipes error is a result of this.

Please can anyone help...?
I have two Windows 2003 Standard Edition servers recently upgraded to Windows 2003 SP1 running SQL 2000 SP3. After the Windows service pack install and reboot the SQL Server service starts OK but the SQL Server Agent does not. This problem is exactly the same on both servers.
The SQL server and SQL agent services are both configured to start using the same Windows domain user account which is not a local Administrator. Starting the SQL agent through services results in an immediate shut down and message:
The SQLSERVERAGENT service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service.
The SQL agent error log shows:
2008-03-04 22:15:55 - ! [241] Startup error: Unable to initialize error reporting system (reason: The EventLog service has not been started)
2008-03-04 22:15:55 - ? [098] SQLServerAgent terminated (normally)
There is no problem with the event log and in fact the System Log shows two relevant information entries:
Event ID 7035. The SQLSERVERAGENT service was successfully sent a start control.
Immediately followed by:
Event ID 7036. The SQLSERVERAGENT service entered the stopped state.
I have done some diagnosis and found the SQL agent will start if the service account is added to the local Administrators group but this is not recommended? I have also tried changing the service account user the correct way using Enterprise Manager - first configuring the SQL server account user, then changing the SQL agent account user - in the attempt that any permissions problems would be reset by choosing to use a different account. But this still results in the same problem of the SQL agent being unable to start unless the service account is a local Administrator.
Anyone have any suggestions, or perhaps just continue with the service account as a local Administrator?
Dear Experts
I want to ask about setting called MAX ERROR where can I find it in Management studio
Thanks lot
Hi guys,
So I received this .trc I am analyzing it… I took it to a sql table and did a top 1 for duration, cpu and reads…
I got the sql code from those ‘top’, execute it and, the longest one it take 65 seconds to run… Problem is it’s a select from a view (code from the view is 10000 lines)… the execution plan is huge (cannot be navigated)… I am kinda list now… What other useful information can I retrieve from the .trc , and in which other way may I improve that 65-second query, if execution plan is a massive.
Per my last discussion, i kept few troubleshooting counters on growth of tempdb and found that:
for about 5-7 queries, tempdb goes up by 10-15 GB every time those queries run.
The current version generation rate is 43.66KB/sec and the cleanup rate is 0.00 KB/sec. The version store size is 18 MB and tempdb file size is 43256 MB.
Also, please refer to below screenshot for tempdb usage for one of those session queries hitting hard on tempdb.
Also, Transaction Isolation level is Snapshot and this is a reporting server with transaction replication set up on it.
I know version store release the older than oldest open transaction, but is there a way we being as DBA can investigate and resolve to regain the stuck space.
Queries are been currently reviewed , but just wanted to make sure if there is something to be done which can fix this tempdb growth?
Please advise!
Ok, For some reason we have a database that is setup in BULK-LOGGED recovery mode and the LDF file has grown to 650GB on a 20gb Database. It has been in bulk-logged recovery mode for some time and from what I am reading this is not good.
So the question I have is to switch this to full recovery mode what do I have to be concerned about? Will I loose data so on so forth.
Any help would be appreciated.
I have a source sql 2005 with the database collation SQL_Latin1_General_CP1_CI_AS and destination with sql 2012 with the same collation.
But the SQL server llvel collation is different, sql 2005 uses Latin1_General_CI_AI and sql 2012 uses "SQL_Latin1_General_CP1_CI_AS"
Now when i load the data from 2005 for one table to sql 2012 i could see special characters in one column. And i dont see that in the source database.
Is there a way to avoid that or is it something we need to manually fix.

Hi guys, I don't even know if is the right place but I am struggling with a situation and maybe you can help me. I have got three table with 85000, 15000 and 20 rows. Table A, B C. I connected the table in excel using the usual schema Data --> From Other Source --> From SQL.

Any suggestion?
I am configuring SQL Resource governor for one of Production server. Following is the scenario
We have AD group as login in SQL server. I am a user member part of domain\BIAdm. When I login using my account SQL Server get permission viadomain\BIAdm.
I am configuring resource governor using user defined classifier. Inside the function I am calling Procedure XP_logininfo to retrieve group name of user belongs to. As limitation of SQL server I am not able to run procedure inside function, So I decided to incorporate the logic in function itself. But the below query throws error on highlighted part. Can you help me in this situation?
DECLARE @WorkloadGroupASSYSNAME
Declare @user_namevarchar(100)
Declare @group_namevarchar(100)
Set @user_name=SUSER_NAME
declare @nttable (name sysnamecollate catalog_default,sidvarbinary(85), sidtypeint)
insert @nt select loginname,sid, isntgroup + 1 frommaster..syslogins
where isntname = 1and loginname = @user_name
insert @ntselectdistinct domain+N'\'+name,sid, sidtype
fromOpenRowset(TABLE NETUSERGETGROUPS, @user_name)
Any suggestion how to get group of user or replacement of OpenRowset(TABLE NETUSERGETGROUPS, @user_name)
Thanks in Advance

Hi All.
I have noticed that whenever there is a deadlock on a FT object, I observe the error below on the windows application event log.
A fatal error occurred during a full-text population and caused the population to be cancelled. Population type is: FULL; database name is DocumentsDB (id: 14); catalog name is DocumentCatalog (id: 42); table name InvoiceBook (id: 454878894). Fix the errors that are logged in the full-text crawl log. Then, resume the population. The basic Transact-SQL syntax for this is: ALTER FULLTEXT INDEX ON table_name RESUME POPULATION.
Hi all,
we know that SQL Server does lock escalation when the number of locks acquired on one level exceed a given threshold (5.000 if I'm not wrong).
The lock escalation is made to save memory needed for storing object locks.
My question: "is the threshold parametric?" I mean, if I have 2GB of Buffer to store locks I need a certain threshold, if I have 200GB of Buffer I have 100x space to store locks...
I'm wondering if, on large SQL Server machine was the case to disable the lock escalation on certain tables...
what do you think?
Hi,
We had to reboot a SQL 2008R2 server tonight so I disabled the agent service (via config manager) so that no jobs would run until we wanted them too. Now I can't set the agent to manual or automatic as I'm getting this error.
I tried starting the service from the command prompt, it does not error but the service in SSMS is not showing as started.
The log from within SSMS show this quite a few times. The service runs under the account "Network Service"
SQLServer Error: 22046, Impersonation error. [SQLSTATE 42000]
Any ideas anyone, really have to get this up and running ASAP.
Thanks

I am using sql 2008 R2 SP3 and using IIS 6.5,
and have got the following error on end user browsers:
[DBNETLIB]ConnectionOpen (SECDoClientHandshake()) SSL Security error
I am a DBA, any way we can investigate deeply on database side ?
Hi, I'm copying date from a sql server 2000 table to a sql server 2008 R2 table using a Linked Server.
I need to be sure the remote table is correct before processing it.
I first delete all the remote table contents and after that, I insert into remote_table from local_table
What happens if the communication is interrupted during the insert?
I mean, Can I be sure all records were copied just checking if record count > 0 ?
Thanks
Diego
I have used Extented event to monitor the occurances of TempDB contention on Production server . I found there are several entried logged in in 30 mints .
Now I am trying to determin if Tempdb contention on PFS, GAM or SGAM page then I will decide if I need to increase the number of TempDB data files on Production server . Currently , There are 8 TempDB Data files configured on its separate Disks .
There are Page_IDs I found in the extented events for Tempdb files -
Page_ID =1 for PFS page
Page_ID = 2 for GAM page
Page_ID =3 for SGAM page
but I found the Below Page_IDs and I know there is a formula that you can use to identify if page is PFS,GAM or SGAM ?Could someone please give me the right formula and will explain me how should I use this formula and what should I look for to determin if page is PFS,GAM or SGAM ? Is there any threshold value for the duration of TempDB contention occured ? Your help will be apprecited .

Hi Team,
There exits various stored procedures, wherein developer has used if exists then update and if not then inserted records.
I would like to know, what is good option, considering with the fact that, stored procedure must be optimized and need to consume less resources.
Thanks
