Using SQL Server From A Service - How To Tell If Recovery Is Complete?
Jan 31, 2008
I have a service (Windows service that is) that's set to automatic startup. The service makes use of one or more SQL server databases and is configured with a startup dependency on SQL Server.
Problem is, the service control manager considers that startup dependency to be satisfied once the SQL server service process successfully starts, but connections from within my service to my databases won't actually succeed until recovery on at least those databases is complete.
Of course, I can do something mundane like retry failed connections a few times, or ensure that I don't attempt to connect to a database until some hard-wired amount of system uptime has passed, but those solutions are just band-aids. The Right Answer, it seems to me, would be to detect when SQL Server has finished recovery and not attempt to connect to my databases before that time.
So, is there any way to determine if SQL server has completed recovery programatically? On a server-wide basis or on an individual database basis? I'm assuming that my service would need to connect to SQL Server with some high-powered credentials (sa or equivalent) to get that information, but that's not a problem in my application.
There is a lot of documention concerning data(base) backups, but I could not find information about how to backup a complete SQL Server instance (data + configuration) or the SQL server configuration (= everything, that is not user payload). you always re-configure your system after restoring, especially because you will forget some settings?I found following things necessary to backup configuration:
server-wide: security: login, roles, ... server objectsserver properties (e.g. collation, connection or memory settings; see SSMS "Server - Properties") per database database settings (SSMS - database - properties)scheme
1. Is there anything missing?In case of a severe system crash I would like to be able to recover the system using a full system image of the virtual machine. However I just create these images after significant changes (e.g. Windows service pack).The SQL server should be backuped independently from these system images.
2. Even if I used SQL Server maintenance plan, choose "backup all databases" and additionally backup resources DB manually I think, that some configuration is still missing, right? Where are the security configuration and server properties saved? In my system database there are some tables, but there is very little content inside, so that the data from the views INFORMATION_SCHEMA* and sys.* obviously is not saved there.SQL Server system objects, such as sys.objects, are physically persisted in theResource database, but they logically appear in the sys schema of every database. URL....What does that mean: Are all DB/table schemes, logins, ... saved in resource DB?
3. Does a usual SQL Server full database backup also contain all settings concerning this database (database properties, logins, ...)?
4. Is there at least a way to backup ONLY the configuration (server-wide and database) without data? The only tool I could find is DACPAC, that exports a database's scheme and some other configuration, but e.g. the database properties are not included: By default, the database created during the deployment will have the default settings from the CREATE DATABASE statement. The exception is that the database collation and compatibility level are set to the values from the source database. URL..
I need to copy a just-created bak file to another drive after the backup task has completed. I don't see anything in the job toolbox which works with file system operations like this. But still it must be a common need..There are ways to script this or use third part tools but I am looking for something native to the sql server 2012 SSMS toolset, if possible.
An alternate approach would be to run the backup job again, after the main backup, and change the destination to the alternate location. But I was thinking that another backup job would probably invoke more overhead on the server than a simple file copy operation. If I do end up taking this approach I could also use the cleanup task to toss older bak files in the alt dir.
I have scripts to refresh database as SQL daily jobs. (O.S is Win2K3 and SQL server 2000 and SP4) It was worked and I got the following message this morning from SQL error log.
BackupMedium::ReportIoError: read failure on backup device '\XAPROD12MASTERXAPRODXAPROD_db_200701290000.BAK'. Operating system error 1450(Insufficient system resources exist to complete the requested service.).
I have a client with a badly corrupted SQL database including things like errors in pages where sysindexes resides among many others. They do not have a good backup. I have had First Advantage Data Recovery Services (www.datarecovery.net) evaluate the database and quote to repair (over $7500).
Does anyone have any experience or reccomendations they can share about this or other companies that provide data recovery services for SQL databases?
We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.
I am having Windows 2012R2 Std with SQL2012SP2. Trying to add SQL cluster node2 but unable to locate the instance name when I click on drop down button.Understand that SQL Server Agent is required but it is not listed as cluster resource. Therefore, I perform the followingFrom Windows Power Shell with Administrator rights
1. Import-Module FailoverClusters 2. Add-ClusterResourceType "SQL Server Agent" c:windowssystem32SQAGTRES.DLL
Error: Add-ClusterResourceType : Unable to locate the cluster service executable on node1.The network name cannot be found.No problem to ping all cluster related names as well as fail-over to and from next available node.
I want to install service pack 3 to my SQL Server 2012 Enterprise running on windows server 2008 R2 Enterprise fail over cluster, I read about the SP installation in technet, its mentioned that the passive node should be patched first and to do this the passive node should be removed from the cluster, I need to know whether I should completely remove the node from windows cluster or remove the node by using SQL Server installer and install the service pack and then add it back to the cluster, Can I do this by pausing the node in cluster and perform the service pack installation ?
A customer is about to replace their PDC with SQL Server running on it. MY companies role is to build the new server, and get their SQL Server running again. I need to have the devices, databases, tables, data and the USERS copied across. I cannot use transfer manager as their will be only 1 instance of SQL Server running on the network.
If all we have is an NT backup is perfomed on the entire disk, i.e. the MSSQL/DATA directory. How do we recreate the databases and their associated tables and also, how do we recreate the User accounts ? Any ideas would be appreciated.

I would like to create a store procedures that will return me a full path by passing a PathID
I started with this code:
DECLARE @path_id int SET @path_id = 5; WITH fullPath (PathID, ParentPathID, Path) AS ( SELECT PathID, ParentPathID, Path FROM tblPath WHERE PathID = @path_id UNION ALL SELECT tblPath.PathID, tblPath.ParentPathID, tblPath.Path AS Path FROM tblPath JOIN fullPath ON tblPath.PathID = fullPath.ParentPathID ) SELECT * FROM fullPath
This code will return this: 1 NULL D: 2 1 Sections 3 2 Bin 4 3 Data 5 4 FinancialReport.doc
What I would like to get is something like this: D:/Sections/Bin/Data/FinancialReport.doc
Any help would be really appreciated. Lost too much time on it already. Thanks, pharvey
Hi all,I'm getting this error when trying to import data from a text file intoSQL Server 2000 (Windows Server 2003) using the DTS import wizard.Any ideas what could be causing this? There aren't any restrictions(that i can find) on the file sizes etc.Thanks in advance.Dave
I have an SSIS package is made up of SQL tasks and dataflows. The dataflows connect to an Oracle database using Native OLE DBOracle Provider for OLE DB (10g). This is the first package dealing with oracle that runs on the server. I can execute the package manually by right clicking and going to 'Run Package' while logged in remotely from the server, but it gets hung up and does nothing if I run it as a job. I always have to quit the job. I can disable everything but the dataflows in the package and the job completes and runs fine.
I have installed SQL server 2005 and after I uninstalled it. and tried to install again but my computer recognize the old version of Sql Server 2005 and only allow to install documentation and client components

Hello--I do not know if this group can help me with SQL Server Reporting Services ... but here it goes. I have a report built on a query and I want to be able to send a parameter (@theWhere) that is a string which is a where clause "(MEGLOMART_TYP_CODE <> 'XYZ' AND MEGLOMART_STAFF_SHORTAGE > 25)" these strings can vary depending on what columns the user selects and what operators they want to use. Generation of proper SQL for the where clause has been verified, I just need to be able to pass these, is there any way to do this...see example query below and how I was planning on using the @theWhere variable...
I have created a small COM in C# so that I can programatically create and execute stored procedures with SMO. At this point the COM has nothing in it but just a test prototype. But when I tried to create the object as follows, I get the error indicated below. It is not a memory issue because I have adequate storage and RAM.

I have a database full of different types of leads some for company A some for company B and so on, each doing a different service. However the leads from B can be used for A and leads from A can be used for B, so I want to merge the data.
Example:
Phone Number Name Home Owner Credit Insurance 727-555-1234 Dave Thomas Yes B 727-555-1234 Dave Thomas Gieco
I would like the end result to be one record:
Phone Number Name Home Owner Credit Insurance 727-555-1234 Dave Thomas Yes B Gieco
Since these were imported into SQL they all have a unique ID, here are the current labels
We've recently upgraded to SQL Server 2014, and are now using SSIS integrated with Visual Studio. We have a SSIS project which contains about 20 packages which are nested in Sequence Containers and executed concurrently. These packages have been set up as project references.
The problem is that when I press the start button to run the packages, they all light up green reporting completion before the data has finished loading into the SQL database. If I press the stop button without waiting a sufficient length of time, then not all of the data gets loaded. i.e. a certain number of rows will be missing from some of the SQL tables.
If I click through to the individual package items and check the data flow progress while running, some of the data flows appear to hang at a certain number of rows without ever reaching completion. The number of rows indicated in the data flow is incorrect - i.e. it will count up to ~150,000 and stay there indefinitely in the running state, when in actual fact there are ~500,000 rows to load.
To clarify, the main package will show all items green and display the "Finished: Success" message in the log window, however when I drill through to certain packages in the set, they'll be stuck in the yellow running state, with no way of knowing whether they've actually completed or not.
My current workaround is to just wait a certain length of time before pressing the stop button. This bug doesn't seem to inhibit rows being loaded - it just incorrectly identifies the point when the load finishes, causing people to terminate the load prematurely.
This issue only occurs if I run the project from the main package container. If I execute the child packages individually, they correctly report the number of rows being loaded and light up green once complete.
I am getting an error in Replication between SQL Server 2005 and SQL Express when "Connecting to Subscriber". Detailed error message is given below. Do we need to increase the logintimeout for "Connecting to Subscriber". How can we increase it?

Any list of commands that require exclusive access in order for the command to complete? I had an instance today where a DBA executed sp_changedbowner command which is the alter database command on a production database and it locked it up.
Pages on a full recovery model database corrupted, need to ensure data loss is minimal for restore operation am thinking about restoring the latest full backup.
in the process of migrating a big db from server 1 to server 2, we had to roll back the change. I started with taking a full db backup and restoring it on server 2 with norecovery, and then a couple logs with norecovery, and then the last log with recovery.
Is there some way to continue this chain now, I mean to change the db to norecovery, or other way to restore logs.
I dont want to do a new full backup.
If I try to do a log restore now i get the message:
Msg 3117, Level 16, State 4, Line 1
The log or differential backup cannot be restored because no files are ready to rollforward.
We have 3 replica AG setup. 2 replicas are in sync/automatic failover, the other(DR Server, different subnet) in asynchronous/manual mode…All these replicas were on sql server 2012, Recently we upgraded DR server to 2014. Since then we have a problem, the AG databases in 2014 instance went into ‘Synchronizing/ in recovery’ state…The SQL server error log has message, the recovery couldn’t start for the database ‘XYZ’…We tried to create a new database and add it to AG , it works for fine for other two 2012 replicas, but on 2014 we see the same issue
I have an almost virgin install of SQLExpres running on a WIN2K Pro system.
Have been able to create and connect db to Access 2000 without problem.
Now I wish to extend to remote connections. Using Surface Area Configuration tool, I changed Remote Connections to Local and Remote.
Whenever this setting contains TCP/IP and I try to restart the service I receive the following errors:
System Log:
The SQL Server (SQLEXPRESS) service terminated with service-specific error 10013.

TDSSNIClient initialization failed with error 0x271d, status code 0xa.
TDSSNIClient initialization failed with error 0x271d, status code 0x1.
Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.
SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.
If I change back to Local Connections Only or Local and Remote using named pipes only, the service starts up again without a problem.
After five days of investigating, researching, reinstalling and waiting I have to ask for help.
Hello! I have the following problem. I developed CLR Stored Procedure "StartNotification" and deploy it on db. This sp calls external web service. Furthermore, this sp is called according with SQL Server Agent Job's schedule. On my PC SQL Server works under Local System account and this web service is called correctly (Executed as user: NT AUTHORITYSYSTEM). But on ther other server the following exception is raised during job running: Date 17.04.2007 16:42:10 Log Job History (FailureNotificationJob)
Step ID 1 Server MSK-CDBPO-01 Job Name FailureNotificationJob Step Name MainStep Duration 00:00:00 Sql Severity 16 Sql Message ID 6522 Operator Emailed Operator Net sent Operator Paged Retries Attempted 0

A .NET Framework error occurred during execution of user defined routine or aggregate 'StartNotification': System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. System.Security.SecurityException: at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.Net. The step failed.
What is the reason of this behaviour? Unfortunately I do not have direct access to this server. I have the following guesses: 1) CORPmssqlserver may have not enough permissions to call web service 2) Something wrong with SQL Server account's permissions 2) Something wrong with SQL Server Agent account's permissions I will take the will for the deed. Thanks.
Hi all, I do understand that it is highly recomended to have aserprate user (perfered a domain user account) for each of the SQL Server service and SQL Agent service. What is the reason behind that? (Someone told me to not run the service with an account that has a powerul privilegs! - I don't undrstanmd this point can you explain it please?) What is the diffrent between: 1- Local System account 2 -Network Service account
We have an issue with a 3 node SQL 2012 Always on availability group. Normal operation is node 1 (primary replica) with node 2 and node 3 as secondary replicas.After some patching, SQL wasn't running on node 1 hence the AG flipped over to node 2. This went unnoticed for some time and the transaction log for one of the AG databases became full on node 2 and node 3. (I think this is because it couldn't commit the transactions on node 1 so couldn't truncate it's t-log?) The DB is using synchronous replication btw.So I started SQL on node 1 and flipped the AG back to node 1 (with a data loss warning but I accepted this).Now the issue is that on node 2 and 3, the DB in question is stuck in a "Reverting / In Recovery" State. I've tried various commands such as ALTER DATABASE SET ONLINE, RESTORE DATABASE WITH RECOVERY etc but these fail stating unable to obtain a lock on the DB.
The weird thing is that on node 1 the state of the DB is "synchronised".how to resolve this issue on node 2 and 3? I've left them overnight (in case they were rolling back transactions, the DB is fairly large) but nothing seems to have happened. remove the DB from the AG in node 2 and 3 and add it back in again, ie recreate the replication?
If you are doing a disaster recovery of an entire SQL 2005 cluster, can you just install SQL server and restore the system database to get the configuration?
Had to re-install SQL server and reformat the hard drive. Prior to doing this, detached the database and saved it. I have re-installed SQL Server (personal edition) and re-attached the database. Only problem is that the database shows "read-only" and I got an error when I unchecked the read only box. Any ideas?
Coming more from Oracle background, I want to do a point in timerecovery test on SQl Server. Let's say database PUBS backed up everynight and Trans log backup 3 time every 6 hours between 6 a.m. and 6p.m. , now we want to create a database PUBS2 and recover data upto2:00 p.m yesterday , i.e. I think applied backup from two night beforethen apply to trans log backup ?? Is that what wehave to and how toapply Trans log? I am not sure. Please script and advise.
I'm working to test out a recovery scenario involving a SQL 2008 R2 2 node cluster. I want to restore it to a standalone server. The nodes are VMware VMs using physical RDM for the shared storage. Using Veeam as the backup tool. Veeam doesn't work with physical RDM so I'm dumping the databases (all Simple) elsewhere to be picked up and replicated with Veeam. No problem there. For my DR I have a vanilla 2008 R2 server being replicated so that I can use it as a base to restore SQL. So far the testing has worked ok. What I'm trying to learn is the best way to restore the cluster to the standalone server and have it look the same to the affected app servers.
The cluster has several instances. In my testing, I've recreated the instances, but I don't think they show up as they do on the cluster. For example, if the Windows server name is SQL01, and I install an instance called SQL-APP, SELECT @@servername while connected to the instance still shows SQL01 but in production it shows SQL-APP. What do I need to do to get everything to match up? I suspect that, while I haven't seen any problems, there could be something I'm missing that would manifest itself later.
Also, in testing, am I better off to delete the cluster server account from AD and join the domain with the DR server under the same name? (this is an isolated bubble so no impact on production).For the purpose of this scenario, assume all other required servers (DC, DNS, application, etc.) are present in the test environment as they would be in production and nothing requires resources outside the bubble. The only item affected is the SQL cluster.
I have an urgent query that we are running SharePoint server 2013 on single server and installed SQL server 2012 on single server, our management decided that we need to configure failover cluster on existing SQL server. I want to confirm that it is possible that we can install failover clustering services on existing SQL server and then add an other server on SQL 2012 for high availability or do we need to first install failover cluster service and then install SQL server for failover clustering.
Recently I watched Microsoft Support WebCast: Microsoft SQL Server 7.0 Common Problems and Resolutions dated August 29, 2000. I am trying to find information for a total disaster recovery for my server. In the webcast the presenter made a reference to a Microsoft article Q240872, "How to Resolve Permission Issues When a Database is Moved Between SQL Servers?". I can't find this article. Since we are working with the scenerio of total diaster, we are starting with a new server. I know that when we tried to recover a database to a new server, the server recognized that the database did not originate on that server. Does anyone have any ideas? Or does anyone know how to contact Microsoft so I can find out how to get a copy of this article? Thanks!
