Transactional Replication Alternative?

Mar 24, 2004

I know this is a mess, but they set up this environment before I got there. There is a very minute chance I may get another SQL server, which is why I ask question 1. But I have to move forward with question 2 until I can confirm another box is possible.

1) Is transactional replication possible if the subscriber is in a failover
cluster?
1b) Am I correct in the idea that the publisher and the distributor can live
on the same SQL Server.

2) Transactional replication aside... do you know an alternative to it?

Here' s my situation. I wish they would have consulted with me prior to
setting this up but nonetheless...I have a database cluster with 2 servers
in it. Failover setup between them. The staging database and production
database live on the same SQL server. When data is written to, or updated on the staging database, I need to replicate it to the production database. I obviously can't setup transactional replication when I virtually only have one server to work with.

>> Individual triggers are out because there are 38 tables and I would need a trigger for each action. SO that's approx 114 triggers. Not viable or safe and just plain wrong.

>> I've considered kicking off a DTS package that will copy the table up but then I would need 38 DTS pkgs. And I don't want to copy the whole database every time for obvious performance issues.

>> I've considered modifying the code in their software so that it reruns
their DB update object after I temporarily change the data source... which is a great alternative, except then I have to worry about data integrity; making sure the primary keys match between staging and production.

Thanx for any input or any ideas beyond what I've written.
Egotistical slander not welcome.

Combining Peer-to-Peer Transactional Replication With Standard Transactional Replication

Dec 1, 2006

Hello,

I'm interested in combining the Peer-to-Peer Transactional Replication and Standard Transactional Replication to provide a scale out solution of SQL Server 2005. The condition is as follows:

We may have 10 SQL Server 2005 (1 Publisher + 9 Subscriber) running transactional replication in the production environment and allow updates in subscribers. To offload the loading of the publisher, we plan to have 2 Publisher (PubNode1 and PubNode2) using Peer-to-Peer Transaction Replication and the rest 8 subscribers will be divided into 2 groups. The subscribers 1-4 (SubNode1, SubNode2, SubNode3, and SubNode4) will be set to be standard transactional replication subscribers of PubNode1, and the rest 4 subscribers (SubNode5, ..., SubNode8) will be set to be standard transactional replication subscribers of PubNode2.

Is it possible to setup above 2 Publisher + 8 Subscriber topology?
Also, could we set the 8 subscribers with updatable subscriptions to achieve each node is updatable?

We do not plan to set all the 10 nodes using Peer-to-Peer Transactional Replication as it is necessary to make sure n*(n-1)/2 (i.e. 45) peer-to-peer connections is reliable. It seems that the maintenance cost is high if the servers are not in a LAN and the topology is very high coupling. So we prefer to divide the 10 nodes into 2 groups and reduce the cost of each node to maintain the connections to all other sites.

That's the scenario.

Any feedback is welcome and appreciated.

Thanks,
Terence

Replication Issues After A Database Restore - Unable To Drop Or Create Transactional Replication

Sep 13, 2007

Hi,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.

Alternative To Merge Replication

Oct 16, 2006



I am involved in a development project of an enterprise level hosted application. The main product is a smart client application, and will soon have an embedded sql express option. At the moment I am building the WM 5.0 mobile application and have been advised against using merge replication to syncronize the databases.

The reasons have been that our main SQL 2005 database is on a hosted server that would have to open ports directly to the internet for the merge replication to do its thing. So far I have built some realy pain in the *** manual synchronization that loops through every table it needs to sync looking for a last modified time... pushing and pulling this way. This way it can pass DataSets through a web service just like the smart client app is working today.

Is Merge Replication acceptable or even safe in a situation like this? Any advice or opinions would be appreciated.

Thanks.

Replication :: Transactional Replication Removal Sequence

Sep 2, 2015

I have been researching on the proper steps or sequence to follow to completely remove SQL Server 2012 Transactional Replication.  I have read articles about using SSMS as well as using replication stored procedures and some procedures use SQLCMD or just regular TSQL executed in SSMS.  I have also read articles where people said all you really need is connect to the Publisher instance, find the publication you want to remove and choose "Delete" and everything will be taken care of behind the scene. I have three SQL servers that participate in transactional replication.  SQL-P (publisher), 

SQL-D (distributor) and SQL-S (subscriber).  Do I need to connect to the distributor instance and the subscriber instance when removing transactional replication or is it just really connecting to the publisher and click delete on the publication? I want everything gone including any metadata, systems tables, distributions db and any other replication objects created during the initial configuration.

Merge Replication Set Off Transactional Replication

Oct 9, 2007

I am working on bringing our disaster recovery site to be a live site. Currently we replicate to one of out servers (server B) with merge replication (from server A). Server A also does one way transactional replication form some table to several other servers including servers at the DR site.

This setup is not going to be fast enough for what we need so I am wondering if a table is receiving merge replication will the merge updates also replicate down the transaction path??

Example...
Server B update a row and merges to Server A. With this update them replicate (via transactional) to Server C??

thanks...

Transactional Replication

Jul 30, 2001

On my distribution server there is a directory called mssql7
epldataunc that houses the bcp, sch and idx files for replications. A directory is created for each publication. Most directories are empty but some contain all the table idx, sch and bcp files for the publication. Some of these files are over 6 month. Does anyone know if these files are neccessary to keep and why do only some publications have these files. I am wondering if they are kept when you push the publicaiton and it errors out originally and you have to restart it? If any one can shed some like on this I would appreciate it.

Transactional Replication

Feb 13, 2001

I have a problem with transactional replication in SQL Server 7. I have two databases (a publisher-distributor server and a suscriber server) and when I do an UPDATE in the publisher database the Log Agent Reader reads the UPDATE as an DELETE-INSERT and when the suscriber pull the suscription and try to do first the DELETE the transactional replication stops because of the Foreign Keys in the suscriptor database (that are the same as the publisher).
If anybody knows how to solve it, please tell me

Thanks

Replication - Transactional - 7.0

Nov 1, 1999

I have two servers networked via workgroups (no domain) and am trying to install Transactional Replication. Everything appears to install correctly, but when I run the initial Snapshot Agent I get the following error -

The process could not create file 'CONCEPCIONC$MSSQL7ReplDatauncCONCEPCION_Erik_Rep lication_Erik_Replication19991029153207Employer.sc h'.
Access is denied.

The SQLAgent is starting with same user account on both machines - admin rights and the same password. I have added this user to the (
epldata) folder permissions as well. I even see a "Employer.sch" file in the directory.

What am I missing?

Transactional Replication

Oct 25, 1999

Hello,

I am planning to implement replication between two servers (either snapshot/transactional). Those two servers are physically connected but we don't have domain concept i.e we connected both servers physically and it can be pinked from each other, but not under any domain (not also under different domain). How should I register SQL server& agent services to start with 'Service startup Account'. In this case I cannot start both servers using same domain Account, they how can I relate...

Thanks

Help... Transactional Replication

May 22, 2003

Hi guys can anyone help me with this issue. if so thankyou kindly.

1. created transactional publication (for tables, stored procs & views )
2. created empty database at subscriber
3. set up pull subscription at subscriber
4. ran the initial snapshot agent at the publisher
5. checked the schema files & found out it hadn't scripted the primary keys on the tables.

Problem: PRIMARY KEY AINT GOIN ACROSS, COULD ANYONE TELL ME IF IVE MISSED SOMETHING? THANK YOU MUCH APPRECIATED GUYS.

? Could it be that it is not picking up the primary keys on the tables because I am replicating stored procs and views with that publication?

? Should I break my publications into 3; say 1 for each object?

Thank you guys for taking the time to read this.

Transactional Replication

May 1, 2002

Hello all! I am setting up my first Replicated database, and want to get this right.

We are a Newspaper, and I will be Publishing the database that is the back end of the web server. The goal is to load balance the web site as well as to have a second identical server in case something goes wrong. Both the Subscriber and the Publisher need to be kept in sync as new articles are posted, so my client will just be updating the Publisher. But I'd like to keep a single set of usage statistics, so I was thinking of using Immediate Updating so the Subscriber can update the Publisher using two-phase commit.

What will happen if the Publisher shuts down and an update is attempted on the Subscriber? Will it just hang? Let's assume the worst - what if my Publisher is kaput? How do I determine that my other database is a Subscriber; and how do I stop it from being a Subscriber?

Thanks in Advance,

SQL Transactional Replication

Jun 28, 2002

Hi

I have a requirement for pushing transactional publication to various subscribers. Each subscriber will need to receive a different subset of rows from a table. So I need all rows published, but with horizontal filtering at subscriber level. Is there a way of applying filtering at the subscription level.

Thanks

Transactional Replication

Sep 11, 2007

I am using transactional replication between two SQL 2005 databases. On Sunday evenings, we run a maintenance plan that rebuilds the indexes on the publisher DB. When the plan runs, the replication receives errors and cannot continue. The error appears to be at the publisher level. The publisher runs continually and the subcriber runs every 10 minutes. The error states "cannot run sp_replcmds" Other than Sunday, everything runs fine.

Thank you

How am I able to select those tables with a key?

Re Transactional Replication

Jan 11, 2006

Hi All!

Need help guys... I'm new to SQL Replication, though I successfully created a transactional replication testing on my machine using PUBS DB and a separate DB.

I'm planning to establish/setup a Transactional Replication. There are two SQL Servers, one is being used by WebApp_1 and the other is being used by WebApp_2.  Both servers are maintain by different administrators and situated on different domain/location (both used Win2003 Server).  We will transfer some data from Server_1 to Server_2. Server_1 will be setup as Publisher and the other is the Subscriber, then additonalServer_3 will be added and will serve as the Distibutor.

My questions are:

1. Do I need to request separate domain account from the two different servers to establish connection to the Distributor?

2. Will the User databases from Publisher in compromise/affected as far as database settings and data are concerned?

3. Any useful links?

Any help provided will be greatly appreciated...

Thanks!

Merge Vs. Transactional Replication

Jul 13, 2001

Hi everybody,

I'm still pretty new when it comes to SQL server and I'd like to get some opinions about replication. I need to set up replication between 10 sites. The database is about 2 GB and at each size about 10 users are entering data. The databases need to be synchronized at least 3 times a day. Now our application developer told us to use transactional replication while I'm thinking of using merge replication.

Can anyone give me some more advice about the pro and cons of either replication type.
TIA

Transactional Replication - Error 207

Jan 19, 2003

Hi Guys,

I have a small problem with the transactional replication when I run the initial snapshot and distributing some of the stored procedures. For eg., Say if the stored procedure has the following statements:

---------------------------------------
create procedure abc
as
declare @paytype varchar(50)
set @paytype='check'

insert into acct select cusname,cusacctno,@paytype from cuspay
---------------------------------------

I get the following error:
for statement:

set @paytype='check'
--------------------
Invalid column name 'check'.
(Source: ServerSQL1 (Data source); Error number: 207)

I tried changing to double quotes. even tried adding article using query analyzer without using EM

exec sp_addarticle @publication = N'ReplicationSrc', @article = N'abc', @source_owner = N'dbo', @source_object = N'abc', @destination_table = N'abc', @type = N'proc schema only', @creation_script = null, @description = null, @pre_creation_cmd = N'drop', @schema_option = 0x0000000000000001, @status = 16
GO

Still I get the same error. The server has SQL server 2000 SP2 running with remote distributor and pull subscription.

Am I missing anything.


Please help.

Thanks,
Anu

GUID's Req'd For Transactional Replication??

Aug 22, 2002

Does SQL Server 2000 (Enterprise Edition), mandate the creation of a GUID on each table used in transactional replication?

I was told that in addition to defining a Primary Key, I "MUST" also define a GUID on each table. As I recall - this is not true. Can someone who's setup Transactional Replication please field this question?

Replication (transactional,merge)

Nov 10, 2001

Hi
This is my problem
1. I have been requested to implement either merge or transactional
replication at my site.The replication will be over a wan
2. The problem i have encountered is that the tables have been denormalized
to such an extent that they do not have primary keys ,this is because all
the logic has been programmed into the application.I do not want to
interfere with the table schema as this will create major problems
in the application
transactional replication requires that tables participating in this type
of replication must have primary keys .IS THERE A WORK AROUND?
3. The second issue is that if i try to implement merge replication i
am sitting with a problem that merge replication requires that all
timestamp fields be removed to participate in merge replication.This
application also has all the logic built into it.Almost all tables have
the timestamp datatype in the rowstamp field. IS
THERE A WORK AROUND FOR THIS PROBLEM

THanks

Transactional Replication Error

May 5, 2006

I am running sql 2000 sp3.
A pull subscription failed with the following.

errormsg: Cannot drop the table 'table_name' because it is being used for replication.

errordetail: Cannot drop the table 'table_name' because it is being used for replication.
(Source: SQLTEST2 (Data source); Error number: 3724)

This error started after a field was dropped and a new field added to one of the articles in the publication - changes were done through Enterprise Manager.

Why does this error come up. The Default Table Article Properties dialog box>>>Snapshot tab has the option "If a table with the same name as the destination table exists at the Subscriber>>>DROP the existing table and recreate it.

So if this is an option in replication for a Subscriber how come the error message says it cannot drop the table.

Any insight appreciated.

Transactional Replication And Log Files

Jul 27, 2007

SQL 2005 (SP1, +2153)
Windows 2003 (SP1)

This is not so much a question as a warning/comment.

I was struggling to understand why the log file on my Merge Replication database was continuing to grow despite having a transaction log backup scheduled hourly.

I finally ran a DBCC OPENTRAN to see if there were open transactions and I got the following (to me, unusual) result:


Oldest distributed LSN : (10:384:4)
Oldest non-distributed LSN : (0:0:0)


When I googled for answers, everything kept coming back with pointers to SQL Transactional replication.

We were doing Merge Replication, so I didn't think the various links were relevant. But as I kept coming up empty for a solution to the issue, I finally went and had a look at the publisher properties and scanned down the list of replicated databases (there's just the one). Voila! The database in question was configured for both Transactional and Merge replication.

How it came to be configured for both Transactional and Merge replication, I do not know. I have a feeling it is somehow embedded in the publication creation script that I created some time ago. When I went to double check, I found the same option set on our Development and Test servers.

So, if you have a merge replication database and you find that you have a log file that is growing uncontrollably, check the publisher properties and look to see whether your database is enabled for transactional replication.

Regards,

hmscott

Transactional Replication Problem

Apr 7, 2008

Guys, we have SQL Server 2005, transactional replication set up with pull subscriber. I need to add more tables to the existing publication. I have followed the steps to do it: added new articles to the publication. Checked the status of the Snapshot agent, ran the agent, but it didn't see any difference in the old and new publications. When I query sysobjects on the subscriber database, I see repl stored procedures related to the new tables that I would like to add to the subscription. Am I missing anything? Please, let me know what to do to modify the publication (to add more tables) and actually be able to see these tables on the subscriber db. I am new to the DBA work, so, please, forgive me if I am not making a lot of sense. Thanks,

If I check the GUI, the article appears to be ticked in the publication.

Generate a new snapshot.

Schema Changes And Transactional Replication

Feb 9, 2004

Hi

If a column is added to a table which is a published article in a transactional replication, is it sufficient to do the following?

- drop subscribers
- amend the publication by dropping the affected table, then re-adding it
- re-pushing to subscribers

Or do I have to drop the entire publication and recreate it?

TIA
