Snapshot Replication Vs. Copy Objects DTS
Jan 24, 2007
I have an application that I wrote that is running in the local office and a remote office. The two offices are connected via a hardware VPN. The connection in the remote office is wireless and can give speeds down to 40kbps.
Each office is running MSDE 2000 and runs off of a separate database with a different name. I would like to have the database from the remote office available in the local office. It doesn't have to be completely current. A 24-hour delay would be fine. Since Transaction replication is not available in MSDE, I can use either Merge or Snapshot. Since the local office wants to allow folks to access the remote office's database without allowing them to affect the remote database (query purposes only), it seems that Snapshot is the way to go.
The database in the remote office is as follows: Data File - 50MB; Log File - 5MB. I don't expect this to grow very fast.
The question I have relates to performance over this slow link. Would I be better off using Snapshot replication or just creating a DTS package and having that run on a nightly basis to copy the database?
Also, with a DTS Package, if the job fails due to the link resetting (remember it is wireless), I would have to configure retries, etc. Would Snapshot replication automatically recognize this failure and try to run again?

I'm running SQL 7.0 SP3 on two different machines (one with additional hotfixes). I'm taking a nightly snapshot of imported data on Server1 and pushing it out to another SQL 7.0 server on our network, Server2. All but one table is copied successfully. On the final table, I receive the message, "The process could not bulk copy into table '"%"'."
Error Information Category: Data Source, Source: Server2, Number 4813.
Full error message: "Expected the text length in data stream for bulk copy of text, ntext, or image data."
I've looked up 4813, but it's pretty ambiguous/generic. Also, when I SELECT from Server1 and INSERT INTO Server2 in the QA, I receive no errors. Does anyone have any insight?

I'm trying to start a new publication. When the snapshot agent runs, it stops on a table with the error "Bulk Copy Failed". If I remove the table from the publication, it just moves the error to the next table it tries to copy. What could cause a bulk copy to fail during a snapshot?

I’m trying to create a DTS Package to copy my sql Server objects to a test Server. The server I’m copying from is UMTS1 and the server I’m copying to is UMTSDEV.
The database name is ProgramSpecs and exists on bother servers. My login is assigned to all server roles on both servers. I have created databases on both servers manually so I’m pretty sure I have all the necessary permissions. I’m using the DTS task ‘Copy Sql Server Objects’ to copy sql server objects and have selected “Drop Destination objects first”.
When I try to execute the package I get the following error:
Error source: MS SQL DMO
Error Description: Invalid OLEVERB Structure [SQL DMO] create file error or UMTS1.ProgramSpecs.LOG
Can anyone tell me what I’m doing wrong?
Thanks

My goal is need to synch couple of tables in QA and Prod. I used "Copy SQL Server Objects Task" in DTS package with copy option "replace existing data". It is trying to truncate and insert new data. But BOL is says "Overwrite existing data in the destination objects with the new data from the specified source".
Let me know your thought about this.

The problem is this: In SQL 2000 DTS there was an option for "Copy
Objects and Data Between SQL Servers". However, this option has been
removed in SQL 2005 SSIS. Apparently the only way to do this in SQL
2005 is to create a .DTSX package in SQL Server Business Intelligence
Developement Studio or VS 2005. You do this by creating a new
Integration Service Project and using the Transfer SQL Objects Task.
Within the properties of this task you can select any of the options
that were available in the SQL 2000 DTS export wizard. I have set up a
test package that will copy a stored procedure from one db to another
but I am unable to get it to work. It runs fine but the result is that
the SP is not copied.
I am new to Visual Studio and I think I probably just need help in
know ing how to run a package in SQL Server Management Studio. I was
able to import the package into SSIS in the Management Studio and run
it without errors not with the expected result (the copy of an SP from
one db to another). I'm sure there are people besides me who would like
to have the ability to easily perform ad hoc copies of objects between
SQL servers. If anyone has any experience with using a SSIS package to
do this please help. Thanks!

I have recently moved from a Microsoft SQL Server 2000 to a SQL Server
2005.
In the good old Enterprise Manager, when I imported a table from a SQL
server to another, I could choose "Copy objects and data between SQL
Server
databases". When choosen, all primary keys, and default values was
copied.
My question is:
Is it possible to do the same in Microsoft SQL Server Management Studio
with
SQL Server 2005? And how do I do it?
I have tried using the "SELECT * INTO NewTable FROM OldTable"
statement, but
it just drops all information about primary keys and default values.
Best Regards

Copy objects and data between SQL Server databases
"
Display the Select Objects to Transfer dialog box, where you can specify both objects and data to copy, if both the data source and destination are Microsoft® SQL Server™ databases. The objects you can transfer include tables, views, stored procedures, defaults, rules, constraints, user-defined data types, logins, users, roles, and indexes. You can transfer objects only between multiple instances of SQL Server version 7.0, from an instance of SQL Server 7.0 to an instance of SQL Server 2000, and between multiple instances of SQL Server 2000.
"
can I apply "Copy objects and data between SQL Server databases"
to run in two different sqlserver 2000 ( not an instance ) . what I mean is I have two different sql servers located in two different locations( I am not using an instance installation) can I still run the copy and get an identical database in both servers.
Q2. if I have two sql server 2000 with different collations (one is binary and the other is the default) will I be able to run the copy wizard and still have an identical copy of sql server in both servers.
I personally tried to run the copy wizard and IT NEVER WORKED FOR ME and I really do not know the reason.
Thanks for your input.

I'm a wee bit of a newbie concerning DTS and have inherited a db with a DTS containing a Copy SQL Server Objects task set to run nightly. Essentially, it does an informal backup of some core data.
Recently, I was notified that one of the tables it copies over is now empty on the Destination db. The DTS shows that it runs successfully with no errors logged, the table in question IS selected to be copied from the Source database, there IS data in the Source database table, and every other table in the Destination database is populated appropriately.
Any ideas on what would cause this one table to be empty without generating any errors?
FYI, running SQL Server 2000.

I just upgraded to SQLServer 2005 Standard. I do development in adatabase on one server. When a solution is completely tested, I moveit to the operational database on a different server. With SQLServer2000, I could just open the .adp file and do File->Get ExternalData->Import to move the objects. That does not work with 2005.What is the recommended method for moving objects from one database toanother? Obviously, the objects that changed will not be the sameevery time.Thanks!Jer

Hello,
I am sure there will be a simple answer to this but it has got me stumped.
Having to move over to Vista with my new machine so I am having to switch to 2005 version for my development but still upload to a 2000 server.
I have had a look at 2005, like the new Management Studio, however I ahve a couple of problems which I can not find the answer to.
Firstly, the SQL Query Builder, where has it gone? I often have to import/export data from Excel files and used to use the SQL query builder to create my queries. If I want to copy all columns it is fine but if I want to import select columns I find it easier to view a list and then just add the ones I want.
Am I missing something here?
Secondly, copying stored procedures, before when running DTS ther were three options, Copy Tables/Views, Data Using Query and Copy Objects.
I used the copy opbjects a lot as it was a very quick way of transfering a group of tables and stored prcoedures that I had created. This appears to have now been replaced with Copy Database, which copies everthing, can can not be used to copy from SQL2005 to SQL2000.
If I want to copy multiple stored procedures from SQL2005 to SQL2000 how is it done now? I have tried finding out but have not been sucessful.
Any help would be greatly appreciated,
Regards,
Lee

I have a SQL2000 database that I need to copy tables from to my SQL2005 database. The table in the 2000 database are owned by a login named tsreader. This login is also in the dbo database role. So, when I access tables I have to prefix tha table name with tsreader. Currently in a SQL2000 database I have DTS packages that pull data over from this database everynight and they work fine. However when I try to do this from SSIS, I get the error "Object does not exist". My assumption is that it is trying to access the database tables as a "select * from tablea" as opposed to "select * from tsreader.tablea".
Any thoughts on how to make this work? I know I have the login correct because it is the same one I use for the SQL 2000 packages. Also, in SSIS it allows me to chose the tables I want yet I still get "Table does not exist at source" when I try and execute it.
Any ideas?
Thanks,
fjk

Hi,
I am getting an error when doing the above.
I create a new SSIS package, drag in an Execute DTS 2000 Package Task, select and embed a DTS package which consists only one one task (as above), and then change the source & destination details (svr + user/pwd). Then when I go to the Copy tab, I get the following error when I hit Select Objects, to view the objects which the embedded DTS package should copy:
SQL-DMO error 21776: general error.
On further inspection, none of the objects selected for copy within the atomic/original DTS package, remain selected for copy within the embedded DTS package.
I have googled to search for an answer to this one, but to no avail. Any ideas would be greatly welcomed.
Thanks,
Tamim.

Hi experts.
Challenge: Datapumping. To copy daily production data from N x 100 SQL 2k servers to one central SQL2k5 server.
Sometimes copying task might demand transferring schema objects like temp tables and procedures from sql2005 to sql2000.
Since system organisation is different, what would be the best approach ?
Thanks

I've been trying to replicate a database to an off site server using snapshot replication. It is scheduled to run every hour but I've noticed when data is changed at the source it never gets replicated to the destination. Does anyone know why?? I can't use transactional replication beause not all the tables have primary keys and they can't be added due to code. Some tables have id colunms and have been created with the Not for Replication option on the subscriber. Any help will be appreciated.
Thanks

I can set up snapshot replication for those tables without foreign key constraints. But if there are foreign keys in the table, there will be error
message indicating that this object can not be dropped because it is referenced by ....
Do you have any remedy for that? Thanks

2 questions:
1) In snapshot replication, can the subsciber send info back to the publisher (even in a manual process)
2) In snapshot replication, do we need a distributor set up between the publisher and subscriber if there will only be a single subscriber, or can we write directly to it?
Thanks so much for any and all help!

Hi Guys,
We have a production server in East Coast (SQL Server 2000 SP2 - Database size is around 30 Gig). We have a reporting server is the West Coast. We need to replicate (transactional replication every one hour) from East coast to West coast. Is there any way that I can take a backup and restore upto the last transaction backup and then start replication agent on the production (by saying schema and data already exist). Basically we don't wan't to snapshot using FTP or bcp through WAN because it is going to be very slow.
If this is possible, will there be any validation problem.
Please help.
Thanks,
Anu

Hi,
I am using SQL SERVER 2005 snapshot wizard to create snapshot. But as soon as i create a snapshot it takes away all the indexes and constraint for the tabels on the subscription end although i have this indexes and constraint on Publisher side.
Can someone help me in finding if their is some setting to create a snapshot without losing indexes and constraints or if their is some other way to do this.
Thanks,

Hi Everybody:
We encounter a difficult problem in our production environment.
I have a merge replicaiton which contains 10 tables from Server s1 and database d1 to Server s2 and database d2. Among those 10 tables 5 of them are true merge tables ( carry data both ways, from publisher to subscriber and from subscriber to publisher). Other 5 tables I would like them to carry data only one way from publisher to subscriber ( never merge data from subscriber). Anyone has any suggestions how I impliment this?
Thanks in advance.

Hello,
We are using Snapshot replication to move data for our Data Warehouse from a server which performs the loading to the production reporting server. We are currently using Sql Server 2005 in both environments. The loading server is setup as the Distributor and Publisher and the production reporting server is setup as the subscriber. However, the replication is not automated instead we only want it to run if the load process is successful. To do this we did not set a schedule for replication but added the jobs that the Replication Wizard created to our own Sql Agent job which manages the load. I have listed the below commands that the sql agent is running for replication in the order in which they are ran.
1) -Publisher [SRVLOADER] -PublisherDB [PRESENTATION] -Distributor [SRVLOADER] -Publication [SRVREPORTER] -DistributorSecurityMode 1
2)-Subscriber [SRVREPORTER] -SubscriberDB [PRESENTATION] -Publisher [SRVLOADER] -Distributor [SRVLOADER] -DistributorSecurityMode 1 -Publication [SRVREPORTER] -PublisherDB [PRESENTATION]
In our own job we run each of these jobs using the EXEC SP_START_JOB() procedure. Each job listed above runs under their own PROXY account.
Finally, we are experiencing an intermittent problem where the Agent will report it is unable to Copy data into "X" table, with "X" being any one of the tables in the reporting database. This has only ever occurred during the automation process and not from manually running each agent job. This problem also might not occur for a couple of days and then might occur 2 or 3 days in a row, which has led us to question the dependability of this approach.
In closing I would like to ask if there is a problem with the way we have set it up? Something we could do to improve the process so it becomes more reliable? Any advice would be greatly appreciated.

Is there anyway to prevent deadlocks during the snapshot replication?
I understand that you can minimize by maybe creating a couple different snapshots (mixing tables to minimize locking while snapshot is being created), but is there any other way?
Thank you
