Transactional Replication - Updatable Subscribers - Image Data Type- Sql Server 2000
Aug 21, 2007
Sql Server 2000
I am looking for bidirectional transactional replication using updatable subscribers (queued or immediate) . Is it possible to replicate the image data from the updatable subscribers to the publisher. I understood that the Image data can't be replicated to the publisher from the updatable subscriber. I am not using the WRITETEXT or UPDATETEXT. I am using just INSERT and UPDATE for image data type transactions.
Any thoughts on this is greatly appreciated.
Thanks in advance

Hi,
I am Using Transactional Replication with Updatable Subscriptions. Is there any limitations in the number of subscribers (Servers) used for this type of replication?
I have a scenario of configuring this replication in 60 Subscribers(Servers). And the replication should be in the Continuous running mode. Will Transactional Replication with Updatable Subscriptions work in this scenario??? Or is it meant to work for less than 10 subscribers?
Please reply asap.
Thanks in advance.

Swapna.B.

Hi,
Transactional replication allows updatable subscriptions where changes at the subscriber are replicated up to the publisher, this can happen via Immediate Updating subscriptions, Queue subscriptions and P2P (new in SQL 2005), all forms of Transactional replication.
Any compared document between merge replication and Transactional with updatable subscribtion ?
Thanks,

So, Microsoft decided that they were deprecating Transactional Replication with Updatable subscriptions. In that case, you have 2 options (if I am correct): Pay for Enterprise (if you are already not) and use peer-to-peer or use bidirectional transactional replication which is basically setting up a transactional from db1 to db2 and also transactional from db2 to db1.
The issue I see in both cases is conflict resolution. With updatable subscriptions, you could specify how to handle the conflict. With either of these 2 options (from what I can tell) you cannot allow the engine to handle this for you.
Any thoughts? Seems like a slap in the face to those who have been using MS for years and a damn good reason for companies that rely on updatable subscriptions to not upgrade to 2012.

I have just started getting the following error from the queue reader but I can't see why.
The Queue Reader Agent has encountered the error ''Row handle is invalid.'' when connecting to ''Database'' on ''ServerName''. Ensure that the publication and subscription are defined properly and that both servers are running.
Does anybody know what it means / how I can fix the problem?
Thanks

Hi All,
I am manually replicating parts of a SQL Server CE database (running windows mobile 5.0) to a centralized SQL Server 2000 database.
My program is throwing an exception whenever I try to insert an image data type into the 2000 server from the PDA. I am using parameterized queries.
Error is as follows:
[error]
System.Data.SqlClient.SqlConnection.OnError()
at
System.Data.SqlClient.SqlInternalConnection.OnError()
at
System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning()
at
System.Data.SqlClient.TdsParser.Run()
at
System.Data.SqlClient.ExecuteReader()
at
System.Data.SqlClient.ExecuteNonQuery()
at
PDASync.Database.ExecuteIDRemote()
[/error]
The code for my ExecuteIDRemote method works fine for other queries. It also works if I remove the image column from the offending query.
Does anyone have any suggestions? Thanks.

Subscription to "Transactional Publication with Updateable Subscriptions" works only one way. Changes take effect on subscriber, but the subcriber is unable to update data on publisher.
I have Sanpshot Agent process running under SQL Server Agent service account with login 'sa.' All agents are running at the Distributor (Publishing Server.)
The subscriber is unable to connect to the Distributor using the SQL Server login.
Following is the error message I get:
Creating Subscription(s)...
- Creating subscription for 'SQL3' (Warning)
Messages
Unable to set the Publisher login for the updatable subscription. You may have to set this up directly on the Subscriber machine using sp_link_publication. (New Subscription Wizard)

I am trying to test simple replication (only tables) of a database that resides on a SQL Server 2005 instance to a SQL Server 2000 instance. The Publisher and Distributer are set up on the SQL Server 2005 instance for Transactional replication. The subscriber is set up on in the 2000 instance. Replication Monitor shows the following error after applying a few scripts:
"Category: SQLSERVER Source SQLSERVER2000 Number: 170 Message: Line 6: Incorrect syntax near
'max'."
Here SQLSERVER2000 is the name of my 2000 instance, as should be obvious.
Beyond this point, replication fails. Any pointers as to where the problem could lie? Is this a known backward compatibility issue? I've checked all tables in the database and none contain any datatype that is new to 2005 (the database was actually created in and for SQL Server 2000.
Replication from 2000 to 2005 works fine, but the other way round is failing as described above. Any clues?

Hi to evebody.
I'm working with the transactional publication with updatable subscriptions provided by SQL Server 2005. The replication works pretty good from the publisher to the subscriber, but I'm having some problems when the data must go from the subscriber to the publisher.
When I do an update in a subscriptor's table, the database engine shows the following error:
21064 - 16 - The subscription is unavailable for immediate updating because it is marked for reinitialization. Try again after the reinitialization completes.
And rollbacks the transaction.
Does anybody knows what to do to solve this problems.
The publisher is a Windows XP with the SQL Server 2005 Developer edition with SP2
The subscriber is a Windows 2003 Server with SQL Server 2005 Developer edition without SP2
I'm using also the inmediate updating subscriptions. Both operative systems have the MSDTC runing.
Thank you in advance.
Sebastian.-
PS: Sorry about my english, it's been a long time without using it.

I doing a transactional replication with two servers. Server A, the Publisher and Distributor. Server B, the Subcriber. I did the replication using a dummy DB for practice purpose and it works fine. When I try to implement the replication in original DB, I found that some tables don't have primary keys and to be able to implement transactinal replication all the replicated tables need to have a primary key. I want to add the primary keys to those tables and also implement the replication but the problem is those tables have data in it. I'm thinking in create the new table and do a DTS to import the data to the new table or it's fine just to modify the table in design to add the primary key "Those table have record in it".
Some of you have any advice to me?

I have tried setting up transactional push replication using stored procedures and using wizards. I have two Publishers that are their own Distributors, and 1 Subscriber. All servers are running SQL 2000 SP4 build 2187. Replication appears to be working correctly, but on the Subscriber, under Replication > Subscriptions, the replication type is showing as 'Snapshot' instead of transactional for both subscriptions.
Any ideas?
Thanks.

I need to merge replicate data to two different types of subscribers:
Clients subscribers which will have a very small percentage of the data from the central database. The data on these machines will be managed using dynamic filtering on host_name()
Server subscribers which will manage a copy of all the data from the central database
There will be far fewer server subscribers than client subscribers.
As I see it I have two options for the configuration
1) Use two separate merge publications one which is filtered and one which isnt
2) Use a single merge publication and setup the filtering so that the server subscribers receive all the rows
Which option is likely to lead to better performance?
With option 1) there would be 2 complete sets of replication metadata which need to be maintained so I am tending towards option 2. Are there any disadvantages in using a dynamic filter to return a very large number of rows?

Hi,
I setup transactional replication between 2005-> 2000 database for only one table. It works fine no problem. I checked replication monitor everything works well.
My Subscription was Push Subscription on Publisher.
This morning I restored main database at publication server, I saw all my publication configuration were gone.
I then went to create a publication and push subscription again..and did it, But when I went to replication monitor.
I checked that Snapshot are being created, but from distributor to Subscriber is saying below message?
"The concurrent snapshot for publication is not available because it has not been fully generated.....lONG CHPPPED off meassage"
Can any body tell me hwo to get over this issue?
Many Thanks

SQL Server 2005 Books Online provides an article entitled, "Initializing a Transactional Subscription without a Snapshot". Is it possible in SQL Server 2000 to initialize transactional replication without a snapshot?
So far, I have been unable to find a similar procedure mentioned in the SQL 2000 Books Online. I was able to follow the 2005 procedure using SQL 2000 until I got to the step that says to enable the "Allow initialization from backup files" option on the "Subscription Options" tab of the "Publication Properties" dialog. But that option does not appear in the SQL 2000 version of the specified dialog box.
Any ideas?

I have a publication on 2000 machine, replicating by pull subscription to a 2005 machine. I added a table to the Articles in the publication. Reinitialized the subscription, and also restarted both the snapshot and log reader agent. I was kind of assuming the publication would automatically create the table on the subscriber, but after a very long wait it is still not there. Am I missing anything?
PS. Distination Object setting : "Action if name is in use" is set to drop and create new, not that that should make any difference since name is not in use anyway.
Thanks

We have a SQL2000 database (Publisher) replicating inserts and updates across a 10Mb link to a SQL 2005 database (Subscriber). The Publisher has two tables we are interested in, 1 with 50 columns and 1 with 15. Both tables have 6 insert/update triggers that fire when a change is made to update columns on the publisher database.
We have set up a pull transactional replication from the Subscriber to occur against the Publisher every minute. We have limited the subscription/replication configuration to Publsih 6 columns from table 1 and 4 from table 2. Any change occuring on any other columns in the Publisher are of no interest. The SQL 2005 database has a trigger on table 1 and table 2 to insert values into a third table. There are around 7,000 insert/updates on table 1 and 28,000 on table 2 per day. All fields in the tables are text.
We are seeing "excessive" network traffic occuring of approximately 1MB per minute (approx 2GB per 24 hrs). We also see that the Distributor databases are getting very large -- upto around 30GB and growing until they get culled. We have reduced the culling intrval from 72 hrs to 24 hours to reduce the size.
Does anyone have any suggestions as to how this "excessive" network traffic can be minimised and how the distributor database size can be minimised. I think that maybe they are both related?
Thanks,
Geoff

Hello,
Are there any requirements that dictate the SQL Server version for the distribution agent for a SQL 2000 publisher with a transactional push subscription to a SQL 2005 subscriber?
Thanks in advance,

I have used skiperrors parameter for 2601,2627 and 20598 errors in my Transaction replication setup. When transactions with above error are encountered, its skipped but Im not getting sql command that is skipped in MSrepl_errors table. Since SQL server 2000 is not saving transaction sequence number in the MSrepl_errors we are not getting the command, which have the errors.
Is there any way to track the commands those are skipped in transactional replication.

Hello,
We previously having two servers A and B. Server A is used for updation of data and the data then replicated to server B. Server B is used for
Server A :
purpose : used for database updation/ modification
SQL Server version : SQL Server 2000 SP 2
Server Z :
purpose : used for Reporting
SQL Server version : SQL Server 2000 SP 2
We were doing Transactional replication from Server A to Server B.
Last month we have broght another server (Server B) with same hardware configuration but having SQL SERVER 2005 installed. This is to speed up our database update process. We have moved some of the database on this new server so that we can achieve our deadlines.
Server B :
purpose : used for database updation/ modification
SQL Server version : SQL Server 2005
I have set up the transactional replication from Server B to Server Z and replication works fine.
However, the issue is after it is started replicating from this new server (Server B) performance of all the queries reduced a lot.(making my life harder)
I didnt expected this as our reporting server is still SQL server 2000.
I have restored the backup of database which was replicated from server A (sql server 2000) and compared execution plan for one of our common query (which is used in most of the reports and which is now taking longer time to provide results)
I found that database which is replicated from Server B (Sql server 2005) is having primary keys. which was not present in the database which replicated from server A(Sql server 2000).
I have then removed the primary key and make the indexes same as previous copy of database(which was replicated from server A) But still the query takes long time.
Execution plan now shows "Table Spool" which was not present in previous copy of database.
Almost every query for this database is taking longer time now.
Can someone suggest me what is wrong and what should I need to fix.
Am I going on the right direction?

I have been asked to write a piece of code that will insert an image object into a database using a stored procedure and the Microsoft Enterprise Library. Has anyone done this before? Do you have any code examples about how to update a database with an image datatype that needs to be chunked, etc...
In this instance, I need to open up a word document and save the contents as an image in a database.

hi, i'm a student doing my final year project. during the user requirements stage, my client proposed storing all files (.doc, .jpg, .mp3) into the sql database. i found out that the way to do this is to write the files as binary data in order to store them in the database. my concern is will this data storage overload the database server? i read somewhere that the retrieval of data as binary data is the same as retrieving text. but the estimation of users is around 27,000.. if i'm not wrong, the sql database server should be MS SQL Server 2005, or at least 2003.

I need to move my database servers from one location to another. The issue is that I have over 200 databases to move and my clients can't afford a downtime. The collective volume of all the databases is over 2.5 TB and growing.
I am thinking to copy these databases in batches over the WAN to the new location and replicate them using Transactional replication till I have all the databases moved and synchronized.
Will it be wise enough to use replication for synchronizing 200 databases or is there a better approach which I can use to move these databases with minimum downtime and compromise on performance of applications.
Note: Migration is from SQL Server 2000 to SQL Server 2005.
Thanks in advance.
