Explicitly Replicating One Record Out Of Scheduled Replication.
Nov 26, 2007
Hi,
I’m having a situation where I have configured replication between remote sites and my head office, after every 24 hours. It is working perfectly. Now I want to modify it as per new business requirement. For this I need to know the answers to following questions. Any help will be appreciated.
Consider sample database with a master and child tables.
1) It is possible to replicate master table immediately and child table every 24 hour?
2) is there any possibility that we can explicitly replicate a single child record when required? For example, people can see master record without the need to see child table records, but if some one want to see some specific record from child table, can it be done?
Regards,

We have a publisher sending data to two remote subscribers. Each of these sites is updating a different field in a particular table with its site name and the current date stamp. This data should then sync to each database to show how up to date the last data change was. This lets us keep an eye on whether sync is good or not.
The problem I've got is one subscriber isn't copying its row to the other servers anymore. It gets the row updates from the other sites in the same table but its own updates to this field aren't getting sent across. Nothing shows up in conflict manager for it and nor should it as no other subscriber should be updating this field. If I validate the subscription the field when then get synced but again no updates after the validation will transfer. The other problem which may be related or indicating another issue is the data transfer rate shown in replication monitor is less than 0.1 rows/sec. Reinitializing isn't an option.

I have an issue that is only occurring in a production
environment. The architecture is filtered merge replication between two SQL
Server 2000 SP4 databases. The publisher is standard edition and the subscriber
is personal edition.
The issue is that is I update certain rows on the subscriber the data is not
replicated to the publisher. Inserts and deletes seem to replicate correctly.
The issue is specific to certain rows in some tables. If I update other rows
the updates replicate correctly. The subscription has been re-initialized once
and it did not fix the issue. The replication process indicates that there was
not data to merge and the subscriber updates remain and are at that point
different form the publisher row values after the sync.
I can reproduce the issue by updating the row, running the sync process, and
checking the publisher database. The synchronization process is executed using
the merge agent ActiveX control.
This issue started occurring after a large conflict was generated during an
earlier synch on this particular subscriber. We have other subscribing
databases that are working fine.
I have already spent 8+ hours on the phone with TCS trying to solve this issue.
If anyone has any ideas or has seen this type of issue before I would appreciate
any direction to try to fix this issue.
Thanks

Hello,
I'm developing a VB.Net for a CE.NET device. I use SQL Server 2000. I use merge replication to synch with the CE.NET device.
I have this problem where a view is not replicating to the CE.NET but my table articles are replicating without problems. All the base tables for the view are replicating correctly.
Any ideas?
Thank you.

I have recently upgraded our Database server from 2005 Standard to 2008 R2 Standard.I am having a problem while replicating Full Text Index in New Infrastructure.
Full text Index was working fine in old infrastructure.
Replication scenario for Old infrastructure
Publisher: SQL Server 2005 Standard
Distributer: SQL Server 2005 Standard
Subscriber: SQL Server 2005 Express with Advance Services
Replication scenario for New Infrastructure
Publisher: SQL Server 2008R2 Standard
Distributor: SQL Server 2008R2 Standard
Subscriber: SQL Server 2005 Express with Advance Services/ SQL Server 2008R2 Standard
Whenever I try to replicate Full text Index by selecting  "Copy Full Text Indexes"= "True" article property in Replication and create snapshot it will automatically set to "Copy Full Text Indexes"= "False" whenever I reopened publication properties or snapshot is created.Is SQL Server 2008 R2 Supports full text Index replication to SQL Server 2005.Do I missed some settings while setting up publication for Full Text Index.

Hi everybody,How is it possible to close any open connections from the connection pool explicitly like on the log off page? So when the users log off from the application I want to close all connections that were opened during the use of application.asp.net forums is the best....thanks,Murthy here

I have multiple applications which can potentially update the same trigger simultaneously. Each application:
(1) Reads the contents of the current trigger
(2) Creates a new trigger based on the current contents
(3) Drops the trigger
(4) Creates the new trigger
I need to insure that once one application begins step (1), then no other application can start step (1) until step (4) has completed.
Any ideas on how this can be done? Some databases have a concept of locking tables explicitly, so for them, I can do:
(0) lock table foo;
(1) - (4)
(5) unlock table foo;
Is there such a concept in mysql or is there another way of accomplishing this?
Thanks,
Eric

I have a Nullable columns. I want the value to be zero if NULL is passed.
1) having a view for every such table,
2) using ISNULL for needed columns in that view
3) using those view for inserts instead of using tables directly.
This way i can reduce the number of places to use ISNULL in all my SPs.I dont want to make it to NOT NULL, as my application impact will be high. And Default constraint does not work here.

Hello.
I have a db dal containing the following code:
SqlCommand cmd = new SqlCommand();
cmd.Connection = dbc;
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "SOME STORED PROCEDURE";
.
.
.
declare some SqlParameters
.
.
.
dbc.Open();
cmd.ExecuteNonQuery();
dbc.Close();
This code, when concurrently running via several threads, yields the following exception:
"The connection was not closed. The connection's current state is open."
My questions are:
1. Why don't .Net allocate another connection from the pool (I try to only concurrently run 2 threads while there are 25 connections in the connection pool) ?
2. How can one explicitly allocate a connection?
3. How do you suggest to solve this problem without a mutex/monitor etc' on the 3 bold lines above and without BeginExequteNonQuery()?
Thank you !

I've been considering implementing a P2P Transactional Replication concept using three different sites. My qustion is:
Instead of have records only available for editing by specific sql servers (partitioning), can I implement some sort of record locking? For exampel all sql nodes have r/w access to all data unless one sql node has the record locked?

How do you skip just one record in transactional replication when you have an error?
I know we can add the -skiperror flag to the distribution agent to skip all errors (for a particular error number). But if we do that, can we get detailed information on every record that was skipped?
My goal is to be able to identify every row that cannot be replicated and has to be skipped.
Thanks!

i have transactional replication setup. recently i found that some of the new records in the publisher are not replicated to subscriber, but the replication is going on as normal with most of the record replicated.
the only this happen is user stop and restart the synchronization.
why this happen, how to find all the records which are not replicated and how to replicate to subscriber now.

A user inadvertantly deleted a record in a table that maintains an identity seed. I attempted to insert the record using SET IDENTITY_INSERT ON, but forgot that this table is an article in merge replication. I am attempting the insert on the publisher and I get the following message:
Msg 548, Level 16, State 2, Line 2
The insert failed. It conflicted with an identity range check constraint in database 'cad', replicated table 'dbo.emmain', column 'empl_id'. If the identity column is automatically managed by replication, update the range as follows: for the Publisher, execute sp_adjustpublisheridentityrange; for the Subscriber, run the Distribution Agent or the Merge Agent.
The statement has been terminated.
How can I re-insert this record??Thanks in advance for any help

Hi gang,
I'm 99% sure this is possible, but I wanted to confirm before I go upgrading one box in our replication scheme without having to do all the others (which are geographically dispersed):
Can an SP2 box replicate (merge replication in our case) with pre-SP2 servers? Most of our servers don't even have SP1 applied, and we're ready to upgrade, but I want to be sure I can do them one at a time rather than all at once.
Cheers,
Matt

We are performing snapshot replications from one server to another, however the permissions are not being taken across.
When we manually reset them, the next replication will quite happily remove all permissions.
Any help appreciated.

I am trying to create an auto off-site backup of an entire database. This would include databases and users. It should also include changes made throughout the day.
Something challenging about this is I want it to also include design changes that may have been done throughout the day.
I understand log shipping or replication can deal with the data part of my solution. But how can I copy over the logins, users, and design changes?
Is it possible to have design changes replicated from publishers to subscribers?

Good Day Gurus
I posted a question about replicating logins to the database and the answer i got about doing a DTS to transfer logins is not good for me, is it possible to replicate syslogins tables so that i can do this if so, how because they are not listed Database and Publications when i try to create a publication, only individual created databases can be seen.
The reason for this is because when the DBA decides to change the user permission, i want the info to be merge replicated to the subscriber. At this moment i can run the DTS to transfer the login but it won't know when the logins have been updated and hence i won't know when to run it.
Thanks in advance

Hi,
I am very new to SQL Server. Plenty of SQL knowledge but the whoe SQL server enviornment is new.
I am working with SQL Server 2005. My task is to generate reports without affecting our live database. I have setup a second server and installed SQL Server 2005 on that too. My thought was that maybe I could mirror or replicate the table I require over to this new server and run my queries from here. Is this easy to do ?
I read that mirroring might not work as it is solely for back up /fall over purposes and that data on the mirrored server would not be accessible.
I have also been looking at SSIS but at the moment this is all a bit like double dutch to me ! Can anyone point me in the right direction, preferably somewhere beginner friendly ie not overly complicated !!
Thanks a mill,
Sophie

I am using Sql 2005 and merge replication. I am relying on the feature where schema changes are replicated to subscribers but I have come across a situation where schema changes stop being replicated.
This is the scenario:
I create a database and publish it for merge replication.
I add subscribers.
If I need to change the published database I can use ALTER TABLE ddl and the subscriber gets the changes.
If I have to add or remove a merge article as part of a database change I specify the @force_invalidate_snapshot=1, @force_reinit_subscription=1. No any ALTER TABLE statements following the article change will NOT be replicated.
Is this a known 'feature'? Is it because @force_reinit_subscription is set to 1?
Can anyone help me?

Hello,
We have four mobile devices that are set up for merge replication via the web. We are not receiving errors but some of the data is not coming over to the devices. If we manually add a record that record will come over, but there is data that is on the server that isn't on the devices. If we run the snapshot for each device (We're using host_name as a filter) nothing happens. If we do validation check we get errors. If we reinitialize all devices it works but the next days data (sql job populates data to the publisher db at night) isn't on the device after syncing the next morning. Any help would be appreciated.

I have a sql 2005 publisher and distributor and a sql 2000 subscribers. for some reason on one of the subscribers i'm getting errors that it can't replicate the UDT's. i tried a new snapshot and made sure it was set not to replicate UDT's but i'm still getting Create Type errors.
would anyone have any idea why it's trying to create UDT's at the subscriber when i specify not to replicate UDT's?

Hi there,
I'm using Sql 2005 merge replication and I have noticed something, I'm not sure if this is true or not:...
My publication is set to replicate schema changes (replicate_ddl = 1). Now, I have noticed that schema changes are only replicated if the current snapshot is valid. Is this right? If so why?
My next question carries on from the first. If I'm about to run a TSQL script on my publisher that will add a column or two to a published table, how do I ensure my snapshot is valid inorder for the ddl changes to be replcated? Should I be using:
EXEC sp_mergearticlecolumn
@publication = <publicationname>,
@article = <article name>,
@force_invalidate_snapshot = 1,
@force_reinit_subscription = 1
on each table I modifiy, after I have added the new column?
Thanks for your help

Hi,
I have a database that is being set up for merge replication (Sql 2005), but there is one table that I only want the schema replicating, not the data - I never want the data to be replicated in either direction. I can see from sp_addmergearticle that you can do something like this for sp's or functions but is it possible to do this for tables?
Regards
Graham

Hello,
I use a merge replication between Sql Server and Sql Server Express.
When I enable a DB for .NET features (eg RoleManager), I have new tables and roles that are created and some GRANT are given on SPs.
When I replicate these DB to another one, none of my roles are replicated and I also loose my roles. Is there a way to replicate also the roles and the permissions ?
Thanks

I am wondering if there is a way to replicate changes in a SQL 2000 DB to 2005 without backing up the DB and restoring it in 2005.
We are running an ERP system using SQL 2000 and are moving to a later version that supports 2005 and we want to test it out before going live but I'd like to sync with the current system from time to time instead of having to convert the DB and get it ready again and again everytime I want to update the data.
Thanks for any help you can offer,
Chad

Hi,
I have a number of "join" tables ie joins records from two other tables for example, an employee may be responsible for more than one product so the join table would look like this:
table name: employee_products
Employee_id foreign key from employee table
product_id goreign key from products table
My question is, how do I replication this table? Replication requires all table to have a primary key field. In this case, both fields are foreign keys and I dont have a primary key as the same data appears regularly in either field.
How should I get around this so I can implement replication? I dont want to have to add another field to be the primary key field.
Thanks
