Backup Of Active Log After Db Failure

Jul 20, 2005

Greetings,
I am seeking information related to this subject.

BOL suggests backing up the active transaction log immediately after a
failure, so that the backup can be used in a recovery scenario if necessary.

This is the relevant text from BOL "Transaction Log Backup":

----//
The transaction log backup created at 8:00 P.M. contains transaction log
records from 4:00 P.M. through 8:00 P.M., spanning the time when the
database backup was created at 6:00 P.M. The sequence of transaction log
backups is continuous from the initial database backup created at 8:00 A.M.
to the last transaction log backup created at 8:00 P.M. The following
procedures can be used to restore the database to its state at 10:00 P.M.
(point of failure).

Restore the database using the last database backup created.

1.. Create a backup of the currently active transaction log.


---// end of excerpt

If the failure results in loss of the instance and/or the log's parent db,
how would we back up that log? Even if we could, what confidence would we
have that the backed up log was not corrupted at failure time?

Thanks,
PSG

Active/Active Cluster Failure - How Do You Rebuild And Rejoin A Node In The Cluster?

Aug 30, 2006

We have (had) an active/active cluster. 2 physical machines,
each running their own instance, clustered together. Node1/Ins1 and Node2/Ins2.



Node2 failed and Ins2 failed over to Node1 as it should. Node2 required that we
rebuild the server (rebuild = reinstall O/S). Now we need to get Node2 back
into the cluster and get Ins2 failed back over to Node2.



Does anyone know, for certain, the correct steps to accomplish this? Obviously,
we could backup everything and completely destroy Ins2 and recreate it on Node2
then rejoin the cluster. But I'm looking for something less destructive.



Is it possible to reinstall SQL, then rejoin the cluster, and then fail Node2
over? Or will there be registry conflictions?



Any help would be appreciated. Also, if you have any links to some official
documentation, that would be great too.



Thanks

How Can You Find Active Connections To A Database So You Don't Have To Wait To Get A Failure When One Exists.

May 8, 2008

Is there a way to find active connection to a database so you don't have to wait for a restore or similar operation to fail. (Which take forever).?



Is there a SMO method or a transact SQL command or something that can be used in an application to detect active connections?



I don't want to have to wait forever to get a failure when you can't perform a operation that require that there be no active connection such detach a database. I want to be able to tell when I can perform a operation which requires no active connection and when I need to use a task without out dropping the connection like copying the schema using SMO methods.



However if there are no connection I can perform a detach copy and attach to create a new database which is considerable faster.

Log Backup Failure

Jun 12, 2008

My backup plan is as follows (SQL2K5)
Weekly full
Daily diff
Hourly log


Hourly log fails daily at particular time with following error -
BACKUP LOG cannot be performed because there is no current database backup.

It works , once I kick off a FULL backup.

I feel there is some activity which disqualifies the log sequence. Any thoughts?

DB Backup Failure

Sep 4, 2007

Hello All,

I have created a Maintenance plan using Wizard, In this plan I am doing full backup of 12 DBs to share drive, I created only one step as full backup. And Scheduled this at 7 pm everyday, the
following is the error I am getting in the Logfile, can some one please through some light on this.

" failed with the following error: "Cannot open backup device
\shq-ss2sql backupSQL_PRODDBWorkFlow_backup_200708291911.bak. Operating
system error 5(Access is denied.).
BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not
established correctly.

SQL Server Instance and SQL Agent are running under domain admin account, Share Drive folder has full control by domain admin.

I am the local admin on the SQL Server box, and I have read, write and delete, create permissions on the share drive for backups folder.

What must be the issue?



Thanks

Transaction Log Backup Failure

Aug 4, 2000

I seem to have a problem with my SQL Server log backup system. First I was receiving alerts that the log file was filling up, so I increased it from 3Mb to 150Mb, but then I got another alert saying the same thing, later on I got an alert saying that the log backup had failed. I then decided to truncate the log and do a full backup after as suggested, however this did not work, I don't know if I am doing something wrong, this is really confusing and frustrating.

Transaction Log Backup Failure

Aug 15, 1999

I have scheduled transaction log backups to occur every 15 minutes with database backups every sunday at 1.00AM and differential db backups every day at 1.30AM.

While viewing the job history of the transaction log backups through enterprise manager, I noticed that one transaction log backup had failed at 1.00AM on sunday. The error message was,

"Backup, CHECKALLOC, bulk copy, SELECT INTO, and file manipulation (such as CREATE FILE) operations on a database must be serialized. Reissue the statement after the current backup, CHECKALLOC, or file manipulation operation is completed. [SQLSTATE 42000] (Error 3023) Backup or restore operation terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed. "

Please let me know what the error message implies. Will there be any problem if the transaction log backup takes place at the same time as the full database backup or diff. db backup?

Thankyou.

SQL Server Backup Failure

Jul 20, 2005

I am having a problem with a regular backup of an SQL Server (MSDE2000) database to a local drive. I initiate the backup once a week, byissuing the required T-SQL, via ADO. In this case, the T-SQL is:BACKUP DATABASE GPRS_Dimensioning_Archive TO local_backup WITHRETAINDAYS=21, NAME='GDA_20040706'Note that "local_backup" is a file sitting on the same physical driveas the database itself, and has > 80 GB free. It is not a RAID device.The database that I am backing up is 1.6 GB. Oddly, the backup ofanother database to the same file was successful; it was ~900 MB.Even more strangely, I also back these databases up to a networkdrive, which has been running successfully for a number of weeks now(longer than the local backup), and continues to work without anytrouble. The resultant backup file is much larger than the one sittingon the local drive (6.8 GB on the network drive vs ~4 GB locally) Thisnetwork drive has less space (~50 GB) and is configured as RAID 0. Itis a Linux box, using Samba to present the drive to the Windowsnetwork.Any ideas?? I am completely stumped. Obviously, Microsoftdocumentation has been particularly unhelpful.The excerpt below is taken from the SQL server error log, covering acouple of attempts.Any help would be greatly appreciated!!!Nick Tompson.2004-07-06 09:56:01.99 spid54 BackupMedium::ReportIoError: writefailure on backup device 'C:Front EndLocal BackupDB_Backup.bak'.Operating system error 112(error not found).2004-07-06 09:56:02.01 spid54 Internal I/O request 0x02672360: Op:Write, pBuffer: 0x02890000, Size: 65536, Position: 4294914560, UMS:Internal: 0x103, InternalHigh: 0x0, Offset: 0xFFFF3200, OffsetHigh:0x0, m_buf: 0x02890000, m_len: 65536, m_actualBytes: 0, m_errcode:112, BackupFile: C:Front EndLocal BackupDB_Backup.bak2004-07-06 09:56:02.01 backup BACKUP failed to complete the commandBACKUP DATABASE GPRS_Dimensioning_Archive TO local_backup WITHRETAINDAYS=21, NAME='GDA_20040706'2004-07-06 09:56:17.08 spid54 Starting up database'GPRS_Dimensioning_Archive'.2004-07-06 09:56:33.11 spid54 BackupMedium::ReportIoError: writefailure on backup device 'C:Front EndLocal BackupDB_Backup.bak'.Operating system error 112(error not found).2004-07-06 09:56:33.11 spid54 Internal I/O request 0x02674360: Op:Write, pBuffer: 0x028A0000, Size: 65536, Position: 4294914560, UMS:Internal: 0x103, InternalHigh: 0x0, Offset: 0xFFFF3200, OffsetHigh:0x0, m_buf: 0x028A0000, m_len: 65536, m_actualBytes: 0, m_errcode:112, BackupFile: C:Front EndLocal BackupDB_Backup.bak2004-07-06 09:56:33.11 backup BACKUP failed to complete the commandBACKUP DATABASE GPRS_Dimensioning_Archive TO local_backup WITHRETAINDAYS=21, NAME='GDA_20040706'

Backup Failure Error Log Messages

Aug 10, 2005

I have not been able to find any details about backup failures forMSSQL 2000. I am researching the following:1. when a backup fails at a certain point during the process does thebackup:A. stop there having recorded some details?B. quit without backing up any of the data it already processed?C. skip the data it cannot read and move on?2. Does the error log record any of the details above? For instance, ifthere is a table that the backup could not write to .bak, does theerror log report exactly where the error was?I need a way to obtain a Backup Exception 'Report' that when a backupfails it can tell me what did not get into the .bak file. I wouldprefer automatic notification. Our Oracle DBs have something setupthat can be run when a piece of the DB does not get backed up lettingthe Oracle DBA know where there are issues.Thank you,Stephanie

SQL 2012 :: SSAS Backup Failure - Possible Cause For That Is Missing

Recently migrated from 2008 to 2012. Everything is working fine; however went to take my first set of backups today and one of them blew up:

Executing the query ...

Backup and restore errors: Unexpected number of disk files associated with database object. Possible cause for that is missing or corrupt cryptokey.bin or detach.log file.

Execution complete

Not finding much online on the specific error.

- Data source is valid
- Can process the cube
- Can query / navigate cube

Next step would be drop/recreate; however this is an older cube that I'd prefer to leave alone at this stage if possible.

Bizarre Maintenance Plan Failure (db Backup)

Jul 23, 2005

I am getting a failure on the db backup job of one of my maintenanceplans. It is coming back with the generic error message of,"sqlmaint.exe failed. [SQLSTATE 42000] (Error 22029). The stepfailed."I then checked the Database Maintenance Plan History page, but thisshows all the steps having run successfully. If I check the drives forthe actual backup files, they exist and look healthy too!There is plenty of space on the drives, so it is not that.I've checked the NT logs and all they say is,"SQL Server Scheduled Job 'DB Backup Job for DB Maintenance Plan 'DBMaintenance Plan for All User Databases''(0xC06E15E2A9E1414087BE19541D167861) - Status: Failed - Invoked on:2005-06-29 21:00:04 - Message: The job failed. The Job was invoked bySchedule 35 (Schedule 1). The last step to run was step 1 (Step 1). "Which doesn't give me any clues.Since the backups have actually run to success, I am going to take offthe option on the maintenance plan to "Verfiy the integrity of thebackup upon completion". Maybe it is this that is causing problems,rather than the backup?Anyone had anything similar?

Failure Of Diff Backup Of Master Database

Error 1326 Logon Failure When Attempting To Backup To Remote Server

Oct 18, 2007

Hi all:

We currently have a production server (prodserver) and backup server (backupserver) in the same domain, and I am attempting to backup dbs from the production box on to the backup box using the following:

backup database db to disk = '\backupservere$ackupdb.bak' with init

when executing from SSMS, I receive the following error:

Msg 3201, Level 16, State 1, Line 1
Cannot open backup device '\backupservere$ackupdb.bak' Operating system error 1326 (Logon failure: unknown user name or bad password)

Here's where the issue lies for me:


Both the production and backup box are running services under the same domain accounts, let's call it "domainsqlagent"

domainsqlagent has domain admin rights on backupserver and prodserver

I can login to both the production and backup servers using the domain account, map drives, hit administrative shares, drag and drop files, etc between the servers

If I use xp_cmdshell to try and simply move a file between prodserver and backupserver, I receive the above error as well. However, if I open an cmd window and execute the move command from DOS, it will successfully move.

There is a development server on the domain as well (devserver) using domainsqlagent to run the service accounts, and I can successfully backup databases from dev to prod, dev to backup, backup to dev, backup to prod, prod to dev, but NOT prod to backup
Finally, if I create a maintenance plan in SSMS, I cannot create a connection to the backup server (error reads the connection may not be configured correctly or you may not have the right permissions on this connection)

The backup server was changed to a different domain (domain2) before I arrived here, but has been switched back now, rebooted, service accounts changed via Configuration Manager, services restarted (and rebooted again for good measure).
Does SSMS use a different security context to create the connections to remote servers? From all my tests, the domainsqlagent account has all the correct rights and is working OK. Could this be a network issue? The network admin and I have been banging our heads against a wall for the past couple of days, so if anyone has seen something like this, I'd appreciate any help.


Thanks,

Craig

SQL Server 2012 :: Query To Count How Many Sessions Are Active And Remain Active Per Hour

Jan 22, 2015

I have a table with the following columns employeeSessionID, OpDate, OpHour, sessionStartTime, sessionCloseTime. I need to see how many users remain active per hour. I can calculate how many logged in per hour, but I am stumped on how to count how many are active per hour. I have a single table that stores login data. I have created a query that pulls out the only the data needed from the table into a temp table using this query. Also note it is possible that the sessionCloseTime is null if the device has not been logged out this would need to be counted a active.

Where I am stuck is how do I count the sessions that remain active per hour until the session is closed with the sessionCloseTime.

There Is Not Enough Disk Space Error While Installing SQL In A Active/Active/Passive Cluster

Mar 5, 2008



Hi

I am having some teething problems while installing SQL on a 3 node cluster. Within the Cluster configuration I have 3 Cluster Groups with each of them having their associated disk resources. All these disk resources physically exist on a SAN.

The actual cluster is running absolutely fine and I can access all the disks from their respective owner node. The problem only starts when I start installing SQL Server 2005 on this cluster. I specify the Cluster group from the Cluster Group Selection and choose the desired partition and then the error message pops up

"There is not enough diskspace on the destination disk for the current SQL Server data files. To proceed, free up disk space to make room for data files, or install the data files to a different drive"

But the disk I am trying to install it on is 264Gb and none of it is used. I have also tried to change it to a different disk within the same Cluster group but to no avail. I have even tried to install it in a different cluster group all together but I get the same error message.

I have googled around havent found anything so far. The disks have got full permissions for the account I am installing SQL with.

Any help will be much appreciated.


Regards

Adnan

Active/Active SQL Server Clustering With Multiple Instances

May 12, 2008

Hi

I am newbie in SQL Clustering. I have set up a Windows Server Cluster with 2 nodes and am having the following problem with Physical Disk resource for cluster groups:

My Default Cluster Group (named Cluster Group) has IP Address, Network Name, Physical Disk and MSDTC resources. In addition to that my Default SQL Server instance resources are also in this group. I had this initial set up for Active/Passive mode.

Now I am trying to set up a SQL Cluster in Active/Active mode. For this I have to install another instance of SQL Server in the existing cluster and make a separate cluster group for its resources. I made a new cluster group (SQL Instance Group) with an IP Address and a Network Name resource for this new instance but I dont have any Physical Disk resource to allocate to it. As such while installing the SQL Server Instance I get stuck when I'm asked to select the quorum disk to be used.

Is it possible to configure two quorum disks, one for each group?
What's the concept of dedicated disks resource for each sql instance in a group? Is this same as the quorum disk? If this is not a shared disk how do I configure a dedicated disk resource for my second cluster group (SQL Instance Group)?

Anyone could please help me out with this?
