Replicated Database Movement From One Server To Other
Oct 5, 2006
Hi All,
I have SQL server 2005 Database which is having following Replication stuff.
1. 6 merge Subscribers
2. 5 Snapshot Subscribers (Push Susbribers)
3. 3 Transactional Publisher
Due to the Performance Issue, there is need to move SQL server from the Current Server to an Higher End Server.
I want to keep all the Replication settings after movement of the Database. Can anyone tell me how to acheive this requirement?
Is there a possibility to keep the Replication settings ? Even we can have the Same System Name to the New Server.
Awaiting response...
Thanks,
Thams.

I am aware that TDE protects data at Rest and not during communication or data in motion (UNLESS you use Encrypted communication channels using SSL certs etc). Hence I am thinking of doing data export from a TDE encrypted database to a database on the instance where TDE is not enabled or supported. I believe it works and need to take care of relationships between tables.The target database is hosted on SQL 2012 standard edition on which TDE is not supported.

I'm trying to replicate a table(s) in access 2000 to MS SQL server 2000/2005 programatically on a timed instance and then have these tables merged in SQL to create one table.
Any guidance appreciated.
Thank you,

Hi,
I'm trying to get my first replication going, and I have set up a database successfully, along with merge replication, however when I attempt to create the first subscriber, I get a permissions issue, regardless of what I do. In the SQLCESA30.LOG file, I get the following entries:
2006/01/07 16:59:36 Hr=00000000 SQLCESA30.DLL loaded 0
2006/01/07 16:59:58 Hr=80004005 ERR:OpenDB failed getting pub version 28627
I posted the initial thread under the "Replication" forum, but am including this 'pointer' post here due to a lack of replies there, and the relevance of this thread to this forum. Please see http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=193693&SiteID=1 for more details.
Thanks.

I have Transaction Replication setup on a Server X. Server X is publisher and distributor. Server Y is the Subscriber.Everything works perfectly. Â But I need to change the Database with a different DB on Server X that is being replicated to Server Y. I have following questions:
 Â
 1-  Do I create a new distributor on Server X and delete the current distributor?
  2- Create a new Replication Setup on Server X and Y ?Â
  3- Delete the subscriber DB on Server Y (Subscriber) ?
  4- Can I just disable the current setup on Server X and Server Y instead of deleting it

I have transactional replication setup from server A to Server B. I wanted to move the subscriber from B to C. What could be the best approach.
1. Backup the DB from Server B and restore on Server C. set the replication between A & C.
2. setup the transaction replication between A & C along between A & B. Test A& C working fine and then remove B.
If I am going with approach 2 , I have to replicate data approx. 70 GB so If I ran both the replication on Server A that will stress as 140 GB of data moving out. How do I control this large movement ? Can the replication be manual synch?

Hi,
We have to move two of our servers in US hosting SQL Server 2000 database to different location. These servers are clustered using MSCS and uses SAN to store database data. The database on this cluster hosts publisher and distributor. The other two sites in Europe host updateable subscribers. We are using transactional replication. The downtime will be around 24 hours during which servers will be physically moved from one location to other. During this time we will keep the two subscribers running and let the changes queued on subscribers. I have listed following steps based on my limited knowledge of SQL Server. Could somebody please advise if this approach is valid and if I have missed any steps?
1. Make sure no users are accessing database
2. Backup database (In case of emergency need)
3. Stop snapshot, Log Reader, Queue Reader and Distributor Agents
4. Stop SQL Server Service and SQL Agent
5. Take OS backup
5. Shutdown the server
6. Ship the servers and OS backup to new location
7. Setup servers at new location and restore OS backup
8. Start SQL Server Service and SQL Agent
9. Start agents listed in step 3
Regards,
Nilesh

I got Server A with 30 Databases and I was asked to move 30 databases to Server B…
But server A is having 2 databases as Publication and Distribution to two different servers….. and Server A is a subscription for 6 Databases from other servers….
Once I move the databases from Server A to Server B…… what is the best way to get the Replications too…. I mean Server B should have 2 Db’s as Pub & Distr and 6 Db’s as Subscription…
Is there any way I can script it out in Server A and run the same script in Server B with some modification…. so that the Replication work…..??
I have Jobs and Maintenance plans…. Which should also move from Server A to Server B…. I know using DTS...... is there any better way..??
Please some one give me ur suggestion on this…
Thanks
Bob

I have a database A on server_1 that is being merge replicated to database B on server_2 which is production a box
NOW
I want to restore database A on server_3 that is being merge replicated to database B on Server_4 which is test box.
How about do I do that with replication being involved?
Thanx

Hi, I have setup a merged replication on two server. Server A contains the Publisher and the Distributor database and Server B contains Subscriber.
If the database at the Subscriber got corrupted. I am thinking maybe i can 'restore' the subscriber database by resynchronising the data from the publisher to subscriber.
But what happen if the Publisher database failed? How should one restore the publisher database and then restore the replication setup?
What will be a good backup/restore strategy for such a setup?

I have a table that was set up with a primary key - that i need to change. The problem is that the database is being replicated to a remote location, and will not allow me to remove or change the primary key on a published database.
Due to the size of the database and bandwith limitations it is not an option to re-initialise the published database.
Is there any to do this without breaking replication

Is there a way to move a SQL replicated database from one server to another without dropping the publication?
I have SQLCE setup with SQL server 2000; I want to redo the server but needs to move my replication to a temp server and then back.
The problem is that I do not want to drop my subscription and recreate it…it needs to stay the same.

We are going to implement either a replicated database or use log shipping to another database to support our reporting needs. Basically we are moving reporting over data off our transactional database.
With this in mind, I have several questions:
Are there any special configurations in terms of disks for a database in this situation?What are the recommended raid types?
Also, we currently store our data in one filegroup and indexes in another so obviously I'll want those on 2 separate physical disks other than the C:. What about the log files? Do I care where they go (on C: or another physical drive separate from C:, data filegroup drive and index filegroup drive)?
Thanks!

When I try to remove a table, it complains because it's part of apublication. I could script the publication and subscriptions suchthat they can be deleted, the table removed, and then added again.But, I not sure if this is the 'best' approach.Anyone faced this challenge before?Regards,gary

I'm a novice with replication and am in need of direction on how to restore replicated databases. Server A replicates 5 databases to server B using transactional replication. Server A also contains the distribution database. I'm perfoming PUSH replication.
The development area asked me to restore Server A with a copy of production data located on server C. After I restored the data from C to A, I noticed that server A was no longer published. Is this normal?
I re-published the 5 databases, but noticed that the Log Reader Agent has now been running for 2 hours. I'm trying to give myself a crash course in replication, but am coming up empty regarding (1) the prefered method for restoring replicated databases and (2) determining why the Log Reader Agent is taking so long.
Any suggestions?
Thanks, Dave

I have a production database which uses merge and snapshot replication. The Merge is for 3 tables. The snapshot is to update the rest of the data once daily. I use a Full recovery model and perform database backups (full, differential) and transaction log backups.
I have a database optimization plan which runs 4 times a week. This plan performs and integrity check and rebuilds the indexes. This optimization plan is growing the transaction log by about 8MB each time it is run and we are running out of space on the drive for our log files. The space is not being reused.
I saw in another post where Gail Shaw suggesting using SELECT name, log_reuse_wait_desc FROM master.sys.databases to see why the log space is not being reused. On the database in question, the above returns "REPLICATION".
A colleague tried to backup the transaction log a couple of times to truncate the log this weekend. She was going to perform a DBCC Shrinkfile command afterwards. But the truncate failed. Again looking into things it seems replication prevented the truncation.
We are looking at stopping the merge replication or even removing it to truncate the log file and then recreate the merge replication. How to handle shrinking the log file for now and then seeing if there are any checks or changes I can perform which will allow the transaction log space to be reused.

Hi
I often deal with a problem when replicated database is down due to
electric outage or any other scheduled type of downtime. Primary
database is up but distribution agent is going down 'after 10 attempts
to connect to replicated database'. That's the problem I think because
not only distribution agent goes in undetermined state and I have to
restart sqlagent service, but I need to go through whole process of
snapshot and applaying it to replicated db. I would like it to
accumulate transactions in distribution database and once replicated db
is up - distribute them.
I wonder if anybody can tell me how to configure distribution thread so
it does not go down after 10 unsuccessfull attempts but stays for day
or two.
Thank you, Gene.

How can I list all of the Subscriptions in a CE Database that was created with the .Net System.Data.SqlServerCe.SqlCeReplication.AddSubscription method?
After I create the CE database in an sdf file, I can connect to it with SQL Servr Mgmt Studio, then see the list of Subscriptions in the Object TreeView, under "Replication"
But I can't find that Subscription list in any properties or methods of System.Data.SqlServerCe.SqlCeReplication or System.Data.SqlServerCe.SqlCeConnection
Should I be looking in RMO features like Microsoft.SqlServer.Replication??
We want to confirm that a local CE database was last synced from the expected SQL Server database by checking the Publisher property of each subscription in the CE database.
Thanks

Hi,
I have transactional replication set up on a DB and run database maintenance scripts (index defrag, update stats, etc) on this DB daily.
Will the maintenance job/scripts also be propagated to the replica (subscriber) causing these maintenance operations to be performed on the replica OR do I need to create separate jobs on the replica DB (subscriber) also? I'm guessing the latter but wanted to verify to make sure I wasn't missing something. Thanks!

I have a publisher database set up for a merge replication. This is using parameterized filter with join filters.
I also have a stored procedure that does deletes & inserts on the table where the parameterized filter is applied to aid in changing a subscriber's eligibility to receive so and so data. I have observed that running the stored procedure takes extraordinarily long and as a result, the log file grows to a size 1.5 - 2.5 times the database size.
At first I reasoned that this might because I had it set up to use precomputed partitions and changing it requires recalculating the partitions. As a test, I turned off the precomputed partitions. Didn't work. I turned on "optimize synchronization" AKA "keep_partition_changes", which normally is not available when you have precomputed partition on, and that didn't work, either.
At this point, I think I can rule out precomputed partitions being a problem here but I'm stumped now what else I should do to reduce the amount of log writes being required. We do need the parameterized filters & join tables, so that can't go.

I have a table named sales, num of rows are 20. total number of rows for stor_id is 5 rows
I assume that when I create a cursor like this one which will have 5 rows from the cursor Now if I print a statement , I assume that I will have the statement 5 times( one for each row) Am I correct...
well, if this is the concept, I am still having one printed statement.. I do not know why , am I doing something wrong?
thanks for help
CREATE PROCEDURE p_cursor @ord_nbr char(4)
declare rst cursor for
select * from sales
where stor_id= 123
open rst
fetch rst
if (@@fetch_status=0)
print ' I may have 5 rows '
close rst

We're very interested in having our application use SQL/e but we can't have the 4 gig limit. It makes sense to me that SQL/e simply should not be able to access a file over the network, and then you wouldn't have any reason to put a 4 gig limit on it.
At that point it becomes a very flexible alternative for remote users that need to have a large amount of data (i.e. documents, images etc.) with them.
We'd love to start building an abstraction layer so that we can support both SQL Server and SQL/e so that we can support network and remote users and not have the nightmare that is SQL Server Express installation. (care of the windows installer group's bugs...)
Thanks! Hoping for a favourable answer!

Hi all
I am wanting to continuously monitor a source table throughout the day and as data becomes available, process it and insert it into one of a number of tables.
I have tried achieving this using a FOR LOOP and setting the halt condition such that it is not stisfiable. However, this has a couple of problems:
1) It runs in a tight loop and consequently degrades system performance enormously.
2) I can't get transactions to work. I would like each iteration of the loop to spawn a new transaction under which the tasks in the loop can run. Therefore, if one of the tasks fails during such an iteration, only the updates affected by that iteration are lost.
Ideally, I would like to be able to put a wait statement within the loop container so that it runs every couple of seconds. And would also like to implement transactions as described above.
All help is appreciated.
Jays :-)

The secondary server for my availability group was recycled. When SQL Server came back online the data movement for a database was suspended. The error log shows:
"AlwaysOn Availability Groups data movement for database 'XXXXXXXXX' has been suspended for the following reason: "system" (Source ID 5; Source string: 'SUSPEND_FROM_RESTART'). To resume data movement on the database, you will need to resume the database manually. For information about how to resume an availability database, see SQL Server Books Online."
I was able to resume data movement with no issue. I would like to understand the technical reason as to WHY the data movement was put in the suspended state and left there upon recycle. I searched for an article that would list possible reasons (BOL, Google, Bing, etc..). I just could not find much information out there on 'SUSPEND_FROM_RESTART'.

Hello everyone,There's an interesting SQL problem I've come across that I'm currentlybanging my head against. Given the following table that contains itemlocation information populated every minute :location_id date_created=========== ============5 2000-01-01 01:00 <-- Don't need5 2000-01-01 01:01 <-- Don't need5 2000-01-01 01:02 <-- Need7 2000-01-01 01:03 <-- Don't need7 2000-01-01 01:04 <-- Need5 2000-01-01 01:05 <-- Need2 2000-01-01 01:06 <-- Don't Need2 2000-01-01 01:07 <-- Need7 2000-01-01 01:08 <-- Needhow would you generate a result-set that returns the item's locationhistory *without* duplicating the same location if the item has beensitting in the same room for a while. For example, the result setshould look like the following :location_id date_created=========== ============5 2000-01-01 01:027 2000-01-01 01:045 2000-01-01 01:052 2000-01-01 01:077 2000-01-01 01:08This is turning out to be a finger twister and I'm not sure if itcould be done in SQL; I may have to resort to writing a stored-proc.Regards,Anthony

Hi all,
I'm getting this error on expanding the Databases node in SQL Server Management Studio Express Object Explorer:
Failed to retrieve data for this request. (Microsoft.SqlServer.Express.SmoEnum)
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.Express.ConnectionInfo)
Could not continue scan with NOLOCK due to data movement. (Microsoft SQL Server, Error: 601)
A similar error message also appeared when I tried opening an existing data connection within Database Explorer in Visual Web Developer Express. (However, the web application ran fine and it managed to access the database normally.)
These errors only appeared recently. Any ideas how to go about solving this issue?
Thanks in advance.

We are using push subscription using transactional replication. Is there a recommended value for retention period on distributionDb? We are using default value of 72 hrs and recently we saw an issue where data was not replicated with an error that subscription was inactive. When I searched, I fid that it is related to the retention period setting on distribution DB.

Peace be on you,
In my organization, we have a database which exceed unto 2 GB. The application on which we are working is developing since the time of asp / cb 6 and in short it is the baby of many developers. It is a kind of ERP which has no documentation.
Problem 1:
=========
Now, to reduce the size of the database we have examined some of the orphan procedures, tables, and columns. Is it possible for me to create a DTS package which create the backup of all the orphan stuff to some other database and delete it from the actual one. Moreover, We still have doubts that some of fields which we think are orphan, might not be. So we need another DTS package which rollback all the changes. (Any Idea for that)
Problem 2:
=========
We want another DTS package which would move the data from one database to another and same rollback DTS for this one. (Any Idea for that)
Problem 3:
=========
How can we use DTS programming to do these tasks ? what benefits do I got from DTS Programming over DTS Wizard.
Any help would be greatly appreciated.

We have a stored procedure that failed with: Could not continue scan with NOLOCK due to data movement
We are running with ISOLATION LEVEL READ UNCOMMITTED. There are other jobs running, some of which might be hitting these tables (all using the ROWLOCK hint - though I know that's not guaranteed), however, this stored proc would not be going near the same rows. But even if they were, we'd be happy with either the before-look or after-look. This needs to be a low-impact job and should have minimal impact on ther other jobs, so we can't take out locks. Is there any hint we can use to do this? e.g. can we tell the query to just wait until the data has stopped moving then try again?
