Standby Server / Replication Or DTS?
Feb 28, 2002I hope to create a 'Standby' server for a critical web application. I am tempted to set up replication, but realize this task could also be done by a scheduled DTS job, which may be much simpler. I have read up on replication and have some reservations about it. A little about our environment: Data does not change very rapidly. Some days maybe no edits, some days maybe changes to 100 rows. The environment is stable, there are few DDL changes....development is essentially over. This system has 10 databases which it uses. Hence, all would need either replication or DTS Transfers. Intended publishing & subscribing servers are on same domain. Both are production servers. I Believe either Snapshot or Transactional would meet our needs if we replicate. There is no user need for replicated data. This is SOLELY a Disaster Recovery motivated situation. Reservations about replication include the hassles with identity columns, the hassles with Subscriber Databases being left in 'Read Only' mode (thereby slowing & complicating the recovery process), the difficulty in cleaning up a server after replication is halted if we abandon replication. My gut feeling is DTS might be best. There are 10 Databases. Sizes (inaccurately) reported are 5 at less than 5 MB, others at the following sizes: 10 mb, 24 mb, 26 mb, 39 mb and one big one: 3000 mb (3 gb). Latency is not a big issue. If these were DTS'd nightly that would be fine. Transactional Replication would be slightly better, but the amount of data change is not high. I would solicit anybody's input on this. Thanks,
View 3 Replies View RelatedImpact On Replication When A Server Goes Into Standby Mode
Sep 1, 2007We have the following scenario:
Server A replicates Database A to Server B.
Server C has Database A on it as well, but in standby mode. We are applying the transaction logs generated by Database A on Server A to the database on Server C leaving it in standby mode each time.
Let's say we had planned maintenance for Server Aand dumped the last set of transactions on Server A in standby mode to be applied to to Server C. What happens to the replica on Server B? When I start to use Server C, can I backup its transactions and apply them to Server A, and then have those transactions replicated to Server B? And then what do I do when the maintenance is complete so that I can swithc back to Server A and have the replication continue on as before the maintenance to Server B?

CRMDatabase
Data changes all the time but can have hourly replication of transaction logs for this example. I've currently researched a sp called update logons but this has to be fed each account name to enable them on the new server. There must be a way to activate all CRMDatabase logons with the new server?
Could someone be kind enough to lead me through a step by step guide on the best solution.
Thanks a lot

Accessing Database In STANDBY Mode While Log Shipping
Jul 31, 2006Hi,
I am testing with Log shipping, I have it setup and it is working just fine. The secondary database was restored with Standby mode and is readonly. I have no problem accessing and querying data from the secondary database but I noticed if changes are made to the primary and I am accessing the database when the restore step to the secondary runs it fails with the following error:
Message
2006-07-31 09:40:54.33 *** Error: Could not apply log backup file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupLogShipCI_REPLICATION_TEST_20060731131501.trn' to secondary database 'CI_REPLICATION_TEST'.(Microsoft.SqlServer.Management.LogShipping) ***
2006-07-31 09:40:54.33 *** Error: Exclusive access could not be obtained because the database is in use.
RESTORE LOG is terminating abnormally.(.Net SqlClient Data Provider) ***
This appears to be because you can not restore to a database that is in use? How do you get around this? Is it possible? How do I query data from the secondary db without worrying about causing log shipping to fail? Do I not worry about it because at somepoint when Exclusive access is obtainable all the logs will be rolled forward, but this could create a wide gap in sychronization between the primary and secondary db's, say if someone or something does not properly log off. I guess I could disconnect all users prior to applying tlogs but that kind of defeats the purpse of having it in read only mode so that data can be accessed? Couldn't really depend on it as a stable source of data for running data extracts? I suppose it could all just come down to timing everything in the appropriate sequence? Anyway.....
To sum up:
Is there anyway to access the standby server without causing the restore process to fail?
Both the Primary and Secondary are SQL 2K5.
Thanks!

Mar 23, 2015We log ship our production database tansaction logs to a secondary database on a separate remote domain.
Incidentally, this was not set up via the "Ship Transaction Logs" wizard, but instead we had to use the various system stored procedures after restoring a copy of the database on the remote domain in standby mode.
We now have an issue where users are unable to access the remote secondary database without having sysadmin privileges. Clearly we want to avoid this!
We want to be able to use Windows Authentication mode on the server of the secondary database. But since the two domains differ, is it possible to even achieve this?
How can we set up read-only access for users on the secondary database without giving them sysadmin privileges?
Replication Issues After A Database Restore - Unable To Drop Or Create Transactional Replication
Sep 13, 2007Hi,I have transactional replication set up on on of our MS SQL 2000 (SP4)Std Edition database serverBecause of an unfortunate scenario, I had to restore one of thepublication databases. I scripted the replication module and droppedthe publication first. Then did a full restore.When I try to set up the replication thru the script, it created thepublication with the following error messageServer: Msg 2714, Level 16, State 5, Procedure SYNC_FCR ToGPRPTS_GL00100, Line 1There is already an object named 'SYNC_FCR To GPRPTS_GL00100' in thedatabase.It seems the previous replication has set up these system viewsSYNC_FCR To GPRPTS_GL00100. And I have tried dropping the replicationmodule again to see if it drops the views but it didn't.The replication fails with some wired error & complains about thisviews when I try to run the synch..I even tried running the sp_removedbreplication to drop thereplication module, but the views do not seem to disappear.My question is how do I remove these system views or how do I make thereplication work without using these views or create new views.. Whyis this creating those system views in the first place?I would appreciate if anyone can help me fix this issue. Please feelfree to let me know if any additional information or scripts needed.Thanks in advance..Regards,Aravin Rajendra.

could you help me ?????
Warm/hot Standby
May 16, 2000We are planning to provide a disaster recovery facility for a production system. Clustering has been ruled out for technical reasons so we are considering either transactional replication or Log shipping.
Microsoft suggested the log shipping option but it seems a bit messy to me and only provides a warm standby in that it only copies log backups to the secondary machine.
Any ideas why log shipping was suggested in preference to transactional replication? Anyone have any experience in this area?
TIA Colin.

Warm Standby
Nov 6, 2001I have inherited a problem that I am hoping someone can help out with. A developer used a perl script to move some backup files from one server to another and then restore the databases on other server (at least we think that is what happened, no one is really sure at this point)
Now I need to take the databases ourt of read only mode and drop them but I get an error 5063 stating that the database is in warm standby and the alter database and sp_dboption statements both fail.
How do I get the databases out of warm standby mode?
Thanks in advance for any help you all can provide.

Standby Restore
Jun 12, 2006
I'm setting up log shipping and am running into an issue with applying the transactions logs.
This is my 5th server that I'm setting up and I take a backup of the source database, restore it with replace on the standby server. Then I take a log backup, copy it over and try and restore on the standby server, but the LSN#'s are off. It tells me it's too late for the log and try an earlier..
The timestamp on my backup is 11:43 and my translog was at noon...
I ran a checkpoint on the source database, but that didn't seem to do anything.
What am I missing?
Thanks

Setup Standby Server
Aug 20, 1999Where can I find a document that describes how to setup and configure a standby server?
I'm new to SQL Server 7 (I like it). We have a NT 4.0 server with SQL Srvr 7. We just bought another Box that will have the same thing on it with the idea if the 1st goes down, the new box is a 'hot' standby...of course a 'cold' standby will be ok too... I'm not fussy at this point. If you have info on both great.
I'm the SQL Srvr 7.0 DBA (my background is Oracle DBA). I've been doing alot of reading!!!
Can some provide the information I need or point me to someone I can contact?
Thanks

Restore Of Log To Standby Server
Jan 14, 2004We are maintaining a stand-by database server by doing a daily manual restore of logs. On weekends we do Reindexing of the tables for performance boost. some of these reindexing jobs take upto 10 Hrs
We have found that the restore of the logs taken in the source server after the reindexing job takes as much time it took to do the reindexing.
Typically 15 transaction log sessions for a day takes 40 minutes to restore. However the restore of the tranlog that was taken after a 10 Hr long reindexing job takes as much time(10 hrs) to do the restore also.
The size of the tranlog does not justify this time frame. ( Size of tran logs after reindex is more than other logs but is less than 3 GB)
I would like to know what exactly is happening during the restore of the tran log. Is it doing the reindexing in the destination system as well?
The destination server (standby) is in non recovered mode all the time.
The interesting thing is that I would only take 8 Hrs to do a full restore of the database. We are using ArcServ software for backup and restore.
We are on SQLServer Enterprise 7.0 sp4 on NT 4 Enterprise on source and destination.
We run SAP R/3 on a MSCS Clustered env.
The source database size is 260 GB
Any Comments?

View 4 Replies View RelatedStandby Reporting Server
Dec 15, 2006We have a process wherein the production DB is replicated to a server.subscriberA nightly and then a job processes the database for reporting services. Whenever the job fails we have to redo the process all over again. By the time we are finished it is already late in the day and our customers dont like it. Our solution for a standby server is as follows:
1. create another server.subscriberB and start same process from server.subscriberA. So, both servers are replicated from the Production server but SubscriberB is set to run half an hour delayed than subscriberA. The purpose is that should subscriberA process fails, we still have subscriberB. Then we could just change the datasource of the reports to subscriberB
2. replicate subscriberA.ReportServerTempDB to subscriberB.ReportServerTempDB
3. replicate subscriberA.ReportServer to subscriberB.ReportServer
Any insights highly appreciated...
How To Duplicate Standby On The Same Server?
Oct 29, 2007I have some doubts on standby.
I will explain my environment.
I have two servers A and B both with Win2003 SP1
In the server A, i have a database sql server 2005 in compatibility mode -> 8.0.
In server B have SQL server 2005 and one database in standby / read-only mode. This base is getting to the transactional hour of the server A and applying in standby database. This works fine.
The problem I have is: I need to get the standby server B and create another database for test using yours files. I can get the files of server A because i have 512kpbs link and would be impractical.
Putting in the standby offline mode, i copying the files to another directory on the same machine, but when I try to create another database using the duplicate files of standby receive the following message:
Msg 1824, Level 16, State 1, Line 2 Can not attach a database that was being restored.
What is the command that I need to execute to attach the new bank without message Msg 1824. The command that executing is below:
USE master CREATE DATABASE ON homo (FILENAME = N'F:MSSQLDATAhomohomo_prd_homo.mdf '), (FILENAME = N'F:MSSQLloghomohomo_prd_log_homo.ldf ') FOR ATTACH
As a newcomer I do not know which command I run before attach to conclude restore.
I execute restore database with homo recovery but the database does not yet exist. If I run the restore standby database with recovery, I lose standby and need to download backup copy the entire database in server A to B using link.
If someone has any idea is welcome.

Restoring Tran Logs To Standby
Jan 22, 2001I have recently implemented a backup solution that keeps our standby server up-to-date with nightly database backup and restores. Ironed out all the problems with syslogins and orphan users. It's been working very well over the past few weeks.
On the production server we do hourly tran log dumps every hour between 8am and 10pm. I would like to implement some form of "log shipping" to bring the window of vulnerability down to 1 hour. By making some alterations to my current process I been able to incorporate the hourly log dumps in the same process.
However, when I try to restore the log on the standby servre I get the following message,
Server: Msg 4305, Level 16, State 1, Line 1
Specified file 'HODB1SQLBACKUPRace_Prd_T_dump.200101231513' is out of sequence. Current time stamp is Jan 23 2001 2:01PM while dump was from Jan 23 2001 3:01PM.
After a bit of investigation I found the dumptrdate field in the sysdatabases table and it was set to Jan 23 2001 14:01. After updating this field to Jan 23 2001 14:01, I ran the load command again but received the same error message.
Is there something else that needs updating on the standby server? Is what I'm trying to do possible in 6.5? Any help or ideas would be greatly appreciated.
Thanks

Read-only And Warm Standby Status

EXEC sp_dboption 'test', 'read only', 'FALSE' by doing this i'm getting this
Changes to the state or options of database 'test' cannot be made at this time. The database is in single-user mode, and a user is currently connected to it.
And when i tried on Enterprise Manager it is saying
Error 5063 database 'test' is in warm Standby.
I cross checked and confirmed that it is not in single-user mode and no one is connected to the database!!
Any help is greately appreciated.
