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?
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.
Any pointers appreciated!
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 ?

I have SQL 7.0, SP2 running on NT 4.0 with SP5. I have a central publisher and
numerous subscribers using nightly merge push replication. There seems to be some
problem with the rollback after a failed attempt at replication. The publisher
states that there was no response from the sub database and that it was suspect.
From the sql logs on the sub, I can see that the db went into recovery mode,
recovered 100%, howerver all the data in the subscribing database has disappered.
The schema of all the tables is intact and the database still reads at its old
size ~2Gigs. I can't see the data though. The publisher or other subscribers have
suffered no similar loss of data. It seems that there was some sort of error when
the database was trying to rollback to where it was before the attempted
replication. Has anyone experienced anythng similar? Anyone know how I can
recover the data?
I ran a dbcc checkdb, but it reported no errors, saying that there were no rows
in any of my replicated tables.
Any help / suggestions are appreciated.

Hi All!
I made a big mess recently and i need an urgent help. We have 12 months of our company data located in 2 sql servers out of which one server contains 9 months of data (Say A)and another contains 3 months of data (Say B).
The server which contains 9 months data was taken a backup in June 1st week and this is the last backup to the databae in this server.
Now i have tried to append the 3 months data to the 9 months data. So i selected the export option of the B and overlooked the option of "Delete destination objects first".
This creared the disaster. It deleted all our 9 months data in A and wrote down the 3 months data in B.
Now i need to receover the 9 months data in A which was deleted.
Any help please.
I tried with Logexplorer evaluation version but it permitted me to only Northwind and Pubs database.
And also i have tried some other tools like MS SQL Recovery but as evaluation products they didnt helped me completely.
Please let me know if you have any other ideas.
Iam in complete risk, now. :(

Satish.

To the point....My company received a disc containing our last year's databaseinformation from the online company that we use for our documentation(They use SQL ). Only thing is, we are a small business and do not havea "server", therefore we do not have sql server, therefore we can't getour documentation off of the disc. The thing is, we're beingaccredited next week and I need this information for accreditationpurposes. I need to know if there is another option to retrieve thisinformation without purchasing Microsoft Server and SQL Server.any advice / help would be much appreciated.CRS

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.
Msg 3013, Level 16, State 1, Line 1

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

SQL Server 2008R2: Enabling Change Data Capture on a replicated database or its tables will have any performance impact on existing transactional replication.Is it possible to use both of them con temporarily.
View 5 Replies View RelatedMy client has on a physical server (A), the following:
1. MS SQL Server 2008R2
2. MS SQL Server (Reporting Server)
The data base is backed up fully daily to another physical server (B).
What the client would like to do is:
1. Backup just the Raw SQL Data with Tables and Views to Server B every 10 mins
Point to be noted is, there isn't any dedicated storage (NAS or SAN) just local disk storage on the server.
The reason for this is they want to run reports against this data every 10-15 mins...
How and what do I need to do to facilitate this?
Hello there
I have a SSIS 2005 DTSX Package which has several Data flow tasks which directly dump data between tables from 2 different databases.
Suppose if my destination database is named, DestinationDB, what recovery model should I select for this database so that my ldf file size does not explode? I want to keep the ldf file as small in size as possible.
Currently I have used Simple Recovery model, and the ldf file size goes to around 80 GB. (Inserting around 200 million rows)
Will Bulk Logged model be a better option?
Also what does a SSIS 2005 Data flow task use internally? (Insert operation or some sort of Bulk Insert between DBs)
Please help.
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?
I have two production servers in the same data center. I need to ensure that database remains available if a catastrophic server failure or a disk failure occurs. I need to maintain transactional consistency of the data across both servers. I need to achieve these goals without manual intervention. I was suggested to use this optionTwo servers configured on the same subnet. SQL Server Availability Group configured in Synchronous-Commit Availability Mode<<<<But I think the correct answer should be Two servers configured in Windows Failover Cluster in the same data center SQL Server configured as a clustered instance<<<<
View 2 Replies View RelatedI am in problem that I have delete data in my production table.
Now how to retrieve it?
I have only Yesterdays Full and Transaction Backup files.
I used the following query for deleting all data.
delete from t1;
Out of using stored procedure, reports and all this staff, I want to know the possible way to make sure that the data inside my Secondary Server Read only database are same as data in my primary server database.
So what is the simple way to do this check?
We have several read-only nodes in our AlwaysOn cluster, which are set to use Synchronous-commit mode, which ensures that the logs are updated on the read-only nodes before any update statements complete. Even with this option, if we query a read-only node before the logs have been processed, we can read old data. I would like to know a strategy to ensure that a read-only query will definitely return up to date information. I had an idea that if I just used a different transaction type, like Serializable, that it might block the read-only query from actually getting the data until after the log file was processed, but I have not tried it, yet.
I would like to move more queries to the read-only nodes, in an effort to offload CPU utilization from the primary node.
I'm trying to move a log file of a database that is part of an availability group. I have been following steps from the article: [URL]
At first this worked fine for me in a test environment. When I tried it in a production environment the database on the secondary went into "Recovery Pending" state and I can't get it out.
I checked to ensure that the dB is looking in the right place for the log file, and it is. It just doesn't seem to actually use the new file. If I start and stop SQL service, the dB comes back up and is fine.
Here are the steps I'm going through and what is happening at each step:
--------------------------------------
:Connect DEVSQL --This is currently PRIMARY
USE[master]
GO
ALTER AVAILABILITY GROUP [DP-AG-DEV] MODIFY REPLICA ON N'DEVSQL' WITH (SECONDARY_ROLE(ALLOW_CONNECTIONS = NO))
[Code] ....
All is good so far. Both the Primary and the Secondard have had their logical files changed, which has not taken affect yet because there has been no failover.
--Make SQL10 the PRIMARY
:Connect SQL10
ALTER AVAILABILITY GROUP [DP-AG-DEV] FAILOVER;
GO
SQL10 is now the Primary for this AG. And, as expected, the database [AG-Test] is in "Recovery Pending" because it is now looking for the log file in the new location. I need to move the file to the new location.
:Connect DEVSQL
--Enable XP_CMDSHELL
sp_configure 'show advanced options',1
go
reconfigure
go
sp_configure 'xp_cmdshell',1
[code].....
This is where the script is failing, returning the error:
Msg 1468, Level 16, State 5, Line 5
The operation cannot be performed on database "AG-Test" because it is involved in a database mirroring session or an availability group. Some operations are not allowed on a database that is participating in a database mirroring session or in an availability group.
Msg 5069, Level 16, State 1, Line 5
ALTER DATABASE statement failed.
I can not get the dB to recognize the log file at it's new location.
If I restart the SQL Service, it comes back fine, which seems to indicate to me that it is not a permission problem and confirms that the file is in the right place.
How do I force SQL to look for the log file again without restarting the service?
I hope someone has seen this one...I've got a very simple web method that returns a DataTable from my database. It worked fine until I changed this line of code:
string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? ORDER BY Timestamp desc";
To this line of code:
string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? AND CategoryID = ? ORDER BY Timestamp desc";
Here is the complete webmethod:
[WebMethod]
public DataTable GetConfession (int ConfessionID, int CategoryID) {
DataTable dt = new DataTable();
dt.TableName = "XMLConfession";
string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? AND CategoryID = ? ORDER BY Timestamp desc";
using (OleDbConnection cn = new OleDbConnection (ConnectionString)) {
using (OleDbCommand cmd = new OleDbCommand (SqlString, cn)) {
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue ("@ConfessionID", ConfessionID);
cmd.Parameters.AddWithValue ("@CategoryID", CategoryID);
cn.Open();
OleDbDataAdapter da = new OleDbDataAdapter (cmd);
da.Fill (dt);
}
}
return dt;
}
To cause the error, all I did was add the AND statement into the query. Now I get this .NET error message every time I try to run this program:
System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Data.Common.UnsafeNativeMethods.ICommandWithParameters.SetParameterInfo(IntPtr cParams, IntPtr[] rgParamOrdinals, tagDBPARAMBINDINFO[] rgParamBindInfo) at System.Data.OleDb.OleDbCommand.ApplyParameterBindings(ICommandWithParameters commandWithParameters, tagDBPARAMBINDINFO[] bindInfo) at System.Data.OleDb.OleDbCommand.CreateAccessor() at System.Data.OleDb.OleDbCommand.InitializeCommand(CommandBehavior behavior, Boolean throwifnotsupported) at System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.OleDb.OleDbCommand.System.Data.IDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
I am using SQL Server Compact Edition 3.5 and C# .NET 2.0. It's worth noting that the web service does this outside of the program as well, so I don't think the problem is in the code that calls it. Also worth noting is that the query itself works fine when I substitute values in and run it in .NET Server Explorer.
Thanks in advance for any assistance.

I am new at MSSQL 2000 DBA thing. and trying to learn more about analysis service/data warehouse/data mining. so is any expert out there can Recommend some good books or web link article to read? Thanks
Background: In my current company the business users maintain a huge quantity of master data using excel. Then a series of SSIS jobs are edited and manually executed.
Goal: the challenge is to replace this process using MDS. One of the requested features is the possibility for the users to edit or insert new master data using the Web UI or the Excel Add-in and when they are done perform a merge of the master data in the target, in this case in the reporting DB.
The perfect solution for me is something like trigger the execution of a SSIS package to export the data from the subscription views to the reporting DB after the business rules are apply to a specific entity.
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?
View 4 Replies View RelatedHello All,
I have to fetch data in an ssis package from a set of web services. what is the best way of doing this?
The web services are session based, this means that multiple calls are needed to complete one operation. like one to log on, second onwards to execute calls, and the last one to log out.
(there is some cookie management also required to logon successfully into the web services).
Should we write a custom task which will fetch the data for us? Or just write a C# component which is invoked from SSIS?

I have an older instance of SQL Server (2000) used for an old installation of Great Plains. Over the years there have been several custom application built to interface various accounting related systems with the data on this server.
Recently there have been several instances where random transactions are being deleted. The folks in the accounting group setup Great Plains to track any deletes from the GL account and determine who did the deletes. They're telling me that the same account we use to launch SQL Server is the account deleting the data.
It's possible that someone knows the login creds for this account and is using it to do some task that's causing the problem, but that's a long shot in my opinion. I rather believe that one of these custom interface apps is causing the problem.
One of the custom interfaces includes several SQL jobs that run that do some truncating and bulk inserting. In each case these jobs are owned by the sa account. If one of these jobs deleted the data would it be reported as being deleted by sa or by the service account since that's the account that launches SQL Server Agent?
