I have just upgraded from 2000 to 2005 and my transactional replication is running very slow, I already have a latency of 10 mins and its getting worse. I'm just using the default agent profile, is there anything I need to change?
Help please.
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?
Hi all,
I am keen to hear peoples perspectives on how much additional load Transactional Replication will have on a server.
Obviously this will depend greatly on the level of transactions in the database, but a general indication would be great (eg 10% increase in overheads).
I am thinking of encorperating this into a new server structure which we are going to be setting up and am unsure as to whether to make the primary server BOTH the publisher and distributor; or make the secondary server the distributor to reduce the load on the primary to only being the publisher.
Basically the secondary server will simply be a 'hot swap' of the primary - so i/o load on the secondary is not going to be an issue.
There may be 2 primary's (if that makes sense) replicating to the hot swap so that if either primary is dropped the hot swap could take over either servers load/responsibilities - not sure if this will make a difference on where to put the roles?
Anyone have any thoughts on this?
Thanks in advance.
Cheers
Hi
I have sucessfully set up transactional replication, allowing the subscriber to update the publisher. All works well for a while, but after a couple of weeks or so it fails, but always for a different reason !
My question is, is there anything that can be done to help replication stay healthy. I had thought of doing regular backups of the database and the transaction log, and then truncating the transaction log.
Any advice, or links to other troubleshooting resource much appreciated.
Hi All,
I am trying to configure Transactional replication with updatable subscription sql server 2005 with service pack 2.

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

Hi There
WHen creating publciations under 2005 i saw a very interesting option under stament delivery, for inserts , updates , deletes there is an option that simply says insert/update/delete statement.
I could find very little in BOL about this under "Article Properties", is this what it soudns like ? FOr example if you say :
update Table set Cloumn = 'whatever', this will not trigger the update sp for each row at the subscriber , will it actually deliver the update statements and literally do the update/insert/delete statement at the subscriber?
Thanx
I have one Oracle Server (Version 10g) with some simple tables which should be replicated to an SQL 2005 Enterprise Server.

i set the publisher to drop the table and create a new one when i reinitialize with a new snapshot. it only works when i remove the unique key constraint. but after that the data in the replicated table has wrong entries. a select count ... will show the exacly same number as an select count ... on the original table direktly on the oracle server. i reinitialzied the replication multiple times with new snapshots. but the problem does not resolve. first i got a unique key constraint. then i typed truncate table ..., after that i removed the the unique constraint and than all data will be imported but there are some entries that are not existing in oracle.
my server is patched with the newest updates for sql 2005 (Version 9.0.3159).
for exempla the following statement will show the same results on oracle and sql 2005:

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
I'm a newbie to Replication and recently setup the following.
Publisher and Distributor on the same SQL2005 server, then I've got 7 subscribers(SQL2000 servers) and I'm using push subscriptions. I'm replicating 5 SQl tables which don't have too many changes and these are scheduled to run every 3 hours. In a few days a large one off SQL update with add an additional 10,000 rows to one of the replicated tables. I was wondering what impact this would have on the above setup i.e are there any sort of limitations here. I'm assuming not but thought I would check. I'm thinking it will just cause additional overhead on the server, but the update is being applied when no users will be using the database.
Any feedback greatly appreciated.
Thanks
Hi,I am trying to set up a Updatable Subscriptions for TransactionalReplication with SQL 2005 (queued updating).I have a stored procedure "SYS_spShellTest" which is replicated to thesubscriber viathe replication option "Execution of the stored procedure":-------------------------------------------------------------ALTER procedure [dbo].[SYS_spShellTest] @cmd varchar(1000)WITH EXECUTE AS ownerasBEGINEXEC @result = master..xp_cmdshell @cmd, NO_OUTPUTReturn (@result)END-------------------------------------------------------------1) If I call "exec SYS_spShellTest" on the publisher the call is alsoexecuted on the subscriber.2) If I call "exec SYS_spShellTest" on the subscriber the call is NOTexecuted on the publisher.How can I make 2) work so that it is also executed on the publisherplease?Thanks a lot,Patrick
View 1 Replies View RelatedWe 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,

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'm currently trying out transactional replication with updatable subscriptions across two 2005 servers.
View 3 Replies View RelatedHello,
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
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.
View 2 Replies View RelatedHi All,
We are developing a system which will have to support more than 3000
subscribers. We will have to support both Transactional replication
and Merge replication.
I checked the following document about SQL 2005 replication <http://
www.microsoft.com/technet/prodtechnol/sql/2005/mergrepl.mspx>. The
document does not clearly specify what is the maximum number of
subscribers supported without a significant performance degradation.
The questions i have are:
1. Given the fact that there will be more than 3000 subscribers, there
will be more than 500-1000 subscribers trying to replicate at the same
time. Will be there be a performance degradtion in such a scenario
2. Has anyone used SQL Server 2005 in a scenario involving more than
3000 subscribers?
3. Will it be better if we develop our own system to perform
replication activity instead of relying on SQL Server 2005?

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?
Wondering if anyone has any experience with SQL Server Express Edition (SSEXP). We're looking at a mobile sales force type model, so a local database on a laptop with no real time network connection. So the users would collect data locally, then connect up to the network every few days to replicate the data to a central server.
So questions.. Has anyone tried anything similar? How stable/mature is SSEXP? Any other thoughts, alternatives or gotchas anyone can think of?
Thanks for the input.
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.
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...
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.
Hi,
I am planning to do a transactional replication from production server to reporting server. In one of my database is having 150 tables in it, only 100 tables are having primary key . Remaining tables are not have primary keys. So i am not able to do transactional replication for those 50 tables. Could any one tell me how i have to approch transactional replication. Because i need to have production data at my reporting server in regular interval.
So pls suggest me .
I am using Sql 7.0 with service pack2.
Thanks!

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
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?
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
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.
Hi
I am tring to implement transactional replication.
How do i publish tables which donot have primary keys?...because transactional replication seems to publish only the tables which has a primary key.

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,
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

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
I want to set up the transactional replication. How many service accounts we need and what kind of permissions it required in windows level?Only two servers we are using. Pub/Distributor and Subsciber.Which option is better Push or pull?
