Login failed for user 'bobjim'. Reason: Password did not match that for the login provided. [CLIENT: ]

November 28, 2015, 12:17 pm
$
0
0

This error is generated when the db.open command in the dll that attempts to connect is run from a service created as a vb.net service project.  It does not occur when the same dll is called from a Windows form.  The dll works perfectly when called from the Windows form.   It appears that the password is being changed or dropped.  It may be that the logon is being attempted with LocalSystem as the user.  The error message is ambiguous - what does  [CLIENT: <local machine>] imply?  Why doesn't it read [CLIENT: bobjim]?

According to the Windows application log, the service starts and stops successfully.

What am I missing?  Is there a setting required for LocalSystem?  Does LocalSystem have to be added to the list of users for the SQL Server?

One other symptom is that when the service starts, the dll can create a log file, but apparently cannot write to it.  In conjunction with the above symptom this makes me suspect that there is a permissions issue.

Here is the connection string with the password obfuscated.

data source=Jim4;initial catalog=ShastaTest;persist security info=true;user id='bobjim';password='xxxxxxxxx';workstation id=JIM4;packet size=4096

The database is on an sql 2012 server configured for mixed mode authentication.  Access to the database with SMC works properly logged on as user bobjim with the same password.

The manifest for the service project was compiled with each of the following with no difference in results.

        <requestedExecutionLevel  level="asInvoker" uiAccess="false" />
        <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
        <requestedExecutionLevel  level="highestAvailable" uiAccess="false" />

The service was installed using srvman.  Here is the properties dialog for the service.

This is the OnStart code in SweepCalREDIEService project

    Protected Overrides Sub OnStart(ByVal args() As String)
        ' Insert code here to define processing.
        SweepCalREDIE.SweepCalRedie.SweepCalREDIE_Start()
    End Sub

Any suggestions would be appreciated.  It is not good practice to require a user to stay logged on to keep the application running for a large enterprise.  The application needs to run as a service and be set up for automatic start to ride through power outages or other interruptions.

Hi Everyone,

I have a requirement to track the sqlserver when any DB changed from multiuser to singleuser.

I want to capture the date and time when anyone change any db from multiuser to single user and save this information in one text or csv file.

How can we do this using powershell?

Please suggest me if there is any other way to do it.

Thanks

TEMPDB - DBCC SHRINKFILE Does not free disk space (SQL SERVER 2008)

After a sudden growth of the TEMPDB data file to approximately 66 GB on production environment i have followed the second method available on MS KB (Method 2: Use the DBCC SHRINKDATABASE command) :

https://support.microsoft.com/en-us/kb/307487

However, after issuing the below script to shrink the file it didn't work and the file remains not shrink with the same 66 GB although the used space of the file now is  220 MB and free space is about 65 GB:

use tempdb
   go

   dbcc shrinkfile (tempdev, 'target size in MB')
   go
   -- this command shrinks the primary data file

   dbcc shrinkfile (templog, 'target size in MB')
   go
 

Is there any required actions to be applied prior to running the DBCC SHRINKFILE script ?

Update  :

When we try the SHRINKDATABASE option , one of the temp db files got shrink while the other showed the following message:

DBCC SHRINKDATABASE: Page 1:8477818 could not be moved because it is a work table page.

What is wait type UCS_SESSION_REGISTRATION?

On one of my SQL 2012 servers I see this wait type is responsible for very high waits - often as high as 60% of the wall clock time. What exactly does it represent? I can find no documentation on it anywhere.

Full SQL version is 11.0.3513. That's 2012 SP1 with security KB 3045317 applied.

CDC confusion - operation sequence of 3,4,1,2 returned as 1,4 by net changes function

November 30, 2015, 5:59 pm
$

I'm struggling to understand what I'm seeing in CDC's returned data and I wonder if anyone can tell me whether they can make sense of it.

I am seeing the following output from a query directly against the change table for a given primary key value - An update followed by a delete and then an insert, (but the delete and insert have the same start lsn)
__$start_lsn                           __$seqval              __$operation    __$update_mask
-------------------------             ----------------------  ------------ ---------------------------------------------
0x00BE03A8000457990085  0x00BE03A800045799001E  3            0x000000000000000000000000000000001000000000
0x00BE03A8000457990085  0x00BE03A800045799001E  4            0x000000000000000000000000000000001000000000
0x00BE04EA00005BC40059  0x00BE04EA00005B030173  1            0x01FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
0x00BE04EA00005BC40059  0x00BE04EA00005B030173  2            0x01FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF



If I execute a call to get net changes with the arguments 0x00BE03A8000457990085, 0x00BE04EA00005BC40059, 'all', I get the follwing:

__$start_lsn             __$operation    __$update_mask
----------------------   ------------    ------------------
0x00BE04EA00005BC40059  1               NULL
0x00BE04EA00005BC40059  4               NULL



I'm not entirely sure about this, but I would expect to see just a single update (4) row from the get net changes function, given that the start and end lsn passed as the arguments specify an interval wherein the row existed at both the start and end of the interval. But I'm also confused about the "delete followed by insert" recorded in the change table, especially since both rows have not only the same (natural) primary key value, but also the same surrogate (identity column) value.

My best guess is that something in the system code might be doing weird stuff with identity insert and reusing the same natural key, and that this is confusing CDC. Can anyone clarify what I'm seeing here?

CDC error;

We have a database enabled for CDC and last few days we encountered this error multiple times
 The Log-Scan Process failed to construct a replicated command from log sequence number (LSN) 
{0026bfad:00073eaa:002d}. Back up the publication database and contact Customer Support Services. [SQLSTATE 42000] (Error 18805)  Log Scan process failed in processing log records. Refer to previous errors in the current session to identify the cause and correct any associated problems. [SQLSTATE 42000] (Error 22859)  The statement has been terminated. [SQLSTATE 01000] (Error 3621)

Checking the sys.dm_cdc_errors we notice this "Violation of PRIMARY KEY constraint 'lsn_time_mapping_clustered_idx'. Cannot insert duplicate key in object 'cdc.lsn_time_mapping'. The duplicate key value 
is (0x0026bfad00073eaa002c)." So we go and cleanup from cdc.lsn_time_mapping and the CDC process continues. But we cannot find the reason why its happening . Also see a connect item from sometime ago.

http://connect.microsoft.com/SQLServer/feedback/details/334459/msit-mso-cdc-capture-job-fails-with-pk-violation-error

But Our server is running sql 2008 sp3 cu2(10.0.5768) . So anyone know if we can still hit that issue? 

note:Also this database has been enabled for CDC for several years and we have started encountering this issue recently.

tail log backup error on IsHeaderWritable

hi all,

steps to reproduce:
a. Restore with recovery to my box(Windows 8.1) or windows server(Windows 2012 R2 Std)
restore database [TestDB]
 
b. Backup normal log
backup log [TestDB]
to disk = 'd:\Backups\TestDB.trn'
 
c. Backup tail log
backup log [TestDB]
to disk = 'd:\Backups\TestDB_tail.trn' with norecovery
 
Then I got following error:
 
Processed 6 pages for database 'TestDB', file 'Odyssey_SD001_Log' on file 1.
Location:     container.cpp:6448
Expression:   IsHeaderWritable ()
SPID:         55

BACKUP LOG is terminating abnormally.

A system assertion check has failed. Check the SQL Server error log for details. Typically, an assertion failure is caused by a software bug or data corruption. To check for database corruption, consider running DBCC CHECKDB. If you agreed to send dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update might be available from Microsoft in the latest Service Pack or in a Hotfix from Technical Support.
 
 
d. Run DBCC CHECKDB
There is no error, I am wondering if either the restore or the dbcc has a bug.

 Microsoft support has identified that is_media_read_only of sys.master_file is set to 1 which is the root cause, we have to either copy data to new database or login as single user and DAC mode to hack the value as below:
select @@servername
GO
use master
GO
sp_configure 'allow updates', 1
GO
reconfigure with override
GO
update sys.sysbrickfiles set status=544 where dbid=?
 
We have hundreds of databases running on the sql box, there is no read only media, just wondering how could this happen, only 3 of us have access to the sql server none of us would hack the database to like this.

chunklets and autogrow

Hello,

I've a discussion with a administrator about the autogrow option or setting a large database file in order to minimize fragmentation. I said that he should reserve diskspace by setting the initial database to a certain amount of GB's.. He responded that"he has HP 3PAR and that works with Chunklets. This are pieces distributed over a number of disks and is not comparable with conventional SAN's".

Now, I've no experience with Chunklets and I would like to know does he has a point?

Rebuilding Index Online Blocks and Causes Resource Consumption Spikes

I have a large terabyte database with about three tables north of 25 GB in size. The database has an extremely high amount of write transactions happening throughout the day. The tables are heavily fragmented. When I attempt an online index rebuild, there is enough intermittent blocking to cause an outage of the associated application. In addition, the machine's CPU and disk latency skyrockets.

Anyone have any suggestions in how to approach?

DBCC_TRACESTATUS        TF 1118: Status = 1, Global = 1, Session = 0                2015-10-20 00:00:00

After reboot:

Property                              Value                                                                        CaptureDate
DBCC_TRACESTATUS         No trace flags enabled                                             2015-10-21 00:00:02.340

What can be the reason? What can be done to turn them on permanently, if its actually a good bet in enabling so

Please suggest, thanks!

Moving Central Management Servers (Registered Servers)

Hi, 

We have all our SQL servers registered in "Central Management Servers" (CMS) in an instance that is due to be decommissioned.   What would the simplest way of moving this CMS to a new instance, is there any way of doing this so that users are unaware and don't have to do anything? It took a while to get people using this central repository and any "inconvenience" and they will be back using their own registered servers. 

Also, as I understand it users need to be members of the ServerGroupReaderRole (msdb) role in order to access this CMS.  This is a bit of a pain and I would like anyone who has SSMS installed to have this role/right by default, what's the simplest way to do this? 

Any suggestions? 

Thanks

Hi there,

On our newly configured SQL Server Windows NT 64 bit - very high memory usage show up.
We have to reboot it to get it to normal (like to 10% RAM) - RAM usage grows continuously - and in about 18 hours it reaches 95% and our website slows down by a great margin. We reboot the server to get it back to normal and so on.

During such outage I ran ---- Select * from sys.dm_exec_requests ----- and result is here.

If I can provide any more information please let me know.

Thanks so much for help.

Performance issues after upgrading to 2014

Hello,

We upgraded a dev database from sql server 2012 sp2 to 2014 (o/s is Windows 2008r2 sp1).  We are seeing bazillions of recompiles which kill our memory, and the related semaphore waits.  Apparently something changed with regard to variables in 2014?  Is there a fix for this?

Why does INSERT hang on S mode (shared) locks?

I thought INSERTs used "X"  mode (exclusive) locks. Does it also acquire "S mode (shared) locks?

Here's why I ask. I'm capturing extended events for lock_acquisition > 1 second and see lots of waits in the range of about 5 seconds (5000000 µS), always for the same INSERT on the same table, and the mode is always "S".
