also how do i check whether it has emergency during my project testing? haha.. i got an idea of switching of the electricity.. hahaha how should i do actually?
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.

View 4 Replies View Relatedin 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.Â

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
View 3 Replies View RelatedWe 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?

Windows Server 2003 SE
SQL 2000 w/ 4
Veritas Netbackup 5.1 w/ MP5 (for backup/recovery)
Sometimes, not always, when I attempt to recovery a database I will follow the process of restoring the DB and it will complete with a status of successful. However when I attempt to view the DB in Enterprise Manager it states (loading) next to the DB - and never finishes.
As I said, this doesn't happen all the time, but of course when it happens I only know to start over, rebuild everything and go through the recovery process again. I am sure this is something simple.
I apologize for my lack of knowledge in regards to SQL.
Any insight greatly appreciated.

I have removed a SQL Server 2000 installation, as need to re-install the OS also backed up the whole "Microsoft SQL Server 2000" folder that contains all the MDF and LDF files of the DBs.
Now i also had some DTS packages there but now when i have re-installed the whole setup; i could not get the DTS packages. Is there anyway to recover the DTS as i have the whole folder that contains the SQL Server information. DBs are attached again but only the DTS are left. There must be some place where SQL Server stores this information.
Can anyone please help me out as its so urgent for my work.
Thanks!
After a crash while running a query, the database now has (In Recovery) next to its name and is totally unaccessible. How long does this is last? Is there something I should do about it or do I just wait?
View 5 Replies View RelatedHello,
I have a problem. I am trying to set up a disaster recovery plan and have ran into some problems. Just so you are aware, we have tried setting up replication but it failed since the database does not have primary keys(don't ask--I have no control) and we have tried to set up log shipping but we do not have the Enterprise version of SQL server so that won't work. The database is over 200GB so shipping by tape or transferring full backups across the wire is impractical. So basically my question is - "What other options can we explore for setting up disaster recovery that do not involve 'substantial' expenditures?"
There is a direct connection set up between the off site data store.
Thanks
Hi,
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,
A test server I was developing on has died and all of my good work was on it.
However I have a copy of the Data folder containing the folloing files:
Test_Data.MDF
Test_Log.LDF
Is it possible to restore my database from these files?
If so how would I go about it?
Many thanks in advance!
Running SQL version 7 on "Terminal" Server I have a database marked in Load Receovery and we are unable to get to it. We tried MS SQL document on how to but we are still unable to recover it!
View 4 Replies View RelatedWhen I try to restore a database on one server from another server, by choosing the ‘From device’ option, I am not able to see any mapped drives. So I always have to copy the backup file to my local drive before performing the restore. Is there any other way to do it?

1. I want some help regarding sql server 7.0.I had taken database backup (complete).And tried to restore in another machine.
It restored successfully. But it does not create any logins/users. But it has some objects owned by user A
If i create login as A and assigning default database, it is giving error and saying the user/role is already existing. Before restoring
also i created login and after restoring I tried to assign the default database, but failed.
I chaged the objects owner and tried again, still it is saying the user/role is existing.
Can you suggest the solution.
2. I had backup of a database of SQL server 6.5. If i tried to restore on SQL Server 6.5/7.0, it is giving error, and saying it is not valid file. Any solution

Hello somebody,
I submitted an update query on a table of 80 million rows, in the weekend. When I returned on Monday, the transaction was still running. I thought some thing wrong happened and cancelled the transaction. It was taking long time to rollback the transaction. I recycled the SQL Server assuming it will do faster recovery. Now I realised that anyway it is going to take lot of time. And SQL server is not going to be up till the database is recoverd completely.
Now can any body suggest me any thing to faster this process or skip this process. I dont know how long it is going to take rollback the transaction which ran for more than 70 hours.
Thanx in advance.
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. :(

I'm looking for something beyond trying to recover databases and/or SQLServer. My group has been tasked with documenting the recovery for 30+ servers that make up our applications infrastructure including SQL, Web, etc. I posted this here as opposed to another forum because I couldn't even find disaster recovery related topics in the other forums.
Our Systems group (Lan, Wan, etc.) isn't really much help at all. Their focus is more on the mainframe and Novell network recovery. Their perspective is that they will get any replacement server back on line in the event of failure but we are on our own from there.
There are three disaster scenarios for which we must plan: 1) A 737 does a nose dive into the Data Center. 2) A hurricane floods the Data Center. 3) A server gets smoked for whatever reason and is no longer useable.
Assume...
- that there were enough survivors to rebuild the network infrastructure at a remote site.
- we have to recover the operating system, additional software, IIS, SQL, applications, etc.
Questions:
What's the best way to capture the server's configuration on an automated basis?
What's the best way to recover the configuration mentioned above?
How do you maintain a current snapshot of any particular server and how do you ensure there's a documented history of the changes?
Does anybody use a centralized backup system? OmniBack, BackupExec?
What's the best/fastest way to get the replacement equipment?
Where else can I look to find this information?
Have I asked all the questions that I should or can you think of one I've missed?
Confused? Ask any questions you wish.

Is there a Stored Procedure or something else that will tell me if a DB is set to Full or Simple recovery?

SQL Server 2000 SP3.
Prior to SP3 the recovery model was switched to simple during transfer (Copy object task) and changed back to the previouis setting after DTS was complete.
Nice thing because performance was increased and T-Log was keep small.
Now I assume that the recovery model is switched to bulk-logged causing the T-Log to explode, to be onest not in all my databases.
1.Is my interpretation regarding recovery model correct?
2.Does anybody knows the reason of this change?
Any suggestion is really appreciate.
Thank you very much - kind regards.
Is it possible we can take the DTS package backup as part of SQL Server Database backup?.
Is it possible to store the script only in the server folder.?
Thanks,

steps to recovery suspect database
Log showed a 614 error and probably is a result of a hardware 0/s problem or ?. The database was not
reloaded before the error.
I was recently was called in to help some people who had a SQL Server database marked as suspect.
I have never had to deal with this situation before. I got the database operational by doing the
following steps. Was there an easier or better way?
Executed statement per BOL procedure to allow updates to system tables.
Removed suspect flag per BOL (BOL says to use sp_resetstatus which I did not find in master or msdb,
however the BOL had the code listed so I typed in the pertinent statement). I do not know what the '^ 256
meant in BOL, I used the status code that the nonsuspect databases had '16400'.
SQL Server would not let me restore into a suspect database so I reset the suspect flag. Could have dropped
the database, however I did not have the information to recreate the database so the restore function would
work.
Put database in single user mode.
restored database.
Removed the ability to update system tables per BOL
Set the database back to multi user mode.
hi,

Once in while becouse of nethwork, or other problem log shipping fails,
so I have to restart log shipping all over starting from restore in stand by mode last full back of my db.IT takes 2-3 hrs just to do this restore !!!
1. So I am asking advice is any way I can bring down time for restore ?
2. Should diffrential backup be taken ?
3. We will not use Custer
