MSSQL Replication
Oct 27, 2004
Our existing SQL Server is experiencing some troubles and we would like to replace it with new hardware. Of course a migration will be in order to move off of this hardware and onto the new.
To better protect our business critical needs we have decided to implement SQL Server Replication. The SQL Server is what helps drive our everyday business. Without it, we are "dead in the water"! The other day, we lost approximately 10 hours of productivity until SQL Services could be restored.
My question is, if it would be wise to have yet a 3rd server used as a Distributor for Replication or if it would be okay to have the Distributor and Publisher on the same server?
I am concerned that there may be performance problems if we place the two roles on the same machine event though the hardware is very good. Below is the important server configuration.
Windows 2003 Standard Edition
SQL Server Standard Edition
Dual 2.4Ghz with HyperThreading
2GB of RAM
RAID5 for MDF Files
RAID1 for LDF Files
Thank you all for your responses and suggestions.

Hello, I am playing around with the replication feature within mssql.
The system that I am developing requires a master database at a remote location, possibly at a data centre and have a onsite database. The idea of having a local database is that the system can be running in the event of no internet connection and all the local databases update the master server and the master server updating all the local databases so they all have the same data.
I have some questions.
1. I create a publication on the master server and setup a subscription on a local database; does information only go 1 way? Or do I need to setup a publication on the local database and setup a subscription on the master server for data to go both ways?
2. What is the best type of replication for information on all databases to be up-to-date with each other, Merge?
3. Is there any limitations with the replication feature that I need to be aware of?
4. Is there anything that I need to keep in mind when I set this up?
5. How much bandwidth does replication take up, I know there are a lot of factors involved when trying to calculate this type of thing but a good idea would be good.
Thank you for all your replies.
*edit* I am testing with 2 copies of mssql enterprise trial

Hi all.
My goal is to make from time to time a (one way) replication from MSSQL server (Win2K) to MySQL (Linux, i mean no ODBC here).
Is it possible and how ?
The preferable way is to use the MSSQL's replication features, but I have another idea - a simple (php, perl - no matter) program on the linux machine which will be "cron"-ed to run at the requested time intervals.
What are your recommendings ?
Thanks in advance for every kind of help.

Hi all
I've got a nagging problem with the snapshot agent not being able to connect to the distributor.... I have a set up as follows.
I've set up the machine as a publisher, and as it's own distributor. Both the SQL Server and SQL Server Agent services are configured to run as the Administrator user (not ideal I know), and I've created a publication ready for replication. (the agent and distributor are on the same machine)
When I try and run the snapshot agent, Enterprise Manager just times out but a log in the event log says:
Event ID: 203
step 2 - The process could not connect to Distributor 'X'.
Thats about all the info I can find, nothing else is being logged.
Can anyone suggest anything I might have missed? - it's driving me up the wall!
Thanks in Advance.

Hi.. I tried to setup MSSQL2000 trans replicatiom using push subscription method. My Publisher is also my distributor. But whenever I started the dstribution agent, I got the following error. It has problem connecting to subscriber's DB with the following error. I had tried that the login is 100% fine. But why this error appear ? Any help?
The name ' ' is not permitted in this context. Only constants, expressions, or variables allowed here. Column names are not permitted.

I am running MS SQL Server 7 with SP3 installed and am having some problems getting replication to work correctly. I want to replicate all tables from one database to another database on the same server. I can setup replication, add publications and add subscriptions without any problem and all goes well until the replication process starts when the job aborts because it cannot find the sp_MSins..., sp_MSupd... or the sp_MSdel... stored procedures. I have used the New Publication wizard to create a Transactional publication, published all tables and allowed the wizard to use the default stored procedures which it says will be created when the subscribers are initialized but although I have created push subcriptions the stored procedures are never created and hence the replication fails whenever the job runs.
I have SA access to the databases concerned and as far as I am aware the jobs are running as my login - can anybody help me out as this is beginning to drive me nuts.
Thanks
Chris

Hi,
I am a bit new to the MSSQL server. In our application, we use so many SQL queries. To imporve the performance, we used the Database enigine Tuning tool to create the indexes. The older version of the application supports MSSQL 2000 also. To re-create these new indexes, I have an issue in running these "CREATE INDEX" commands as the statements generated for index creation are done in MSSQL 2005. The statements include "INCLUDES" keyword which is supported in MSSQL 2005 but not in MSSQL 2000.
Ex:-
CREATE INDEX IND_001_PPM_PA ON PPM_PROCESS_ACTIVITY
(ACTIVITY_NAME ASC, PROCESS_NAME ASC, START_TIME ASC, ISMONITORED ASC)
INCLUDE
(INSTANCE_ID, ACTIVITY_TYPE, STATUS, END_TIME, ORGANIZATION);
Any help in creating such indexes in 2000 version is welcome.
Thanks,
Suresh.

I've been tasked to move our production databases on MSSQL 2000 to 2005. I've supported MSSQL since version 6.5 and performed migrations to successor versions.
Current Environment is MSSQL 2000 32-bit with current Service Packs.
I've performed mock migrations on Test servers upgrading all Production instances simultaneously from MSSQL 2000 to 2005 32-bit. The Test environment is identical to Production minus server name, IP etc. Also I have a separate server with MSSQL 2005 installed where I use the DETACH / ATTACH and BACKUP / RESTORE method for migration / acceptance testing. There are approximately 30 databases totaling 70 GB. This has gone as expected and fairly successful. Vendors have been coordinated with to update code and staff for acceptance testing.
I'd prefer going directly to MSSQL 2005 64-bit instead if possible due to memory benefits etc. This is where I'd like some feedback prior to borrowing a 64-bit server for testing.
Upgrade options:
1. Is it better to migrate from MSSQL 2000 32-bit to 2005 64-bit via:
a. DETACH / ATTACH
b. BACKUP / RESTORE
c. Is one method more advantageous relating to the end result?
2. Regarding XP clients, have issues been experienced with the default SQL Server driver or is an alternate recommended for XP clients to connect to a MSSQL 64-bit server databases?
3. If you have performed this migration and have relevant experience please pass them along.

DB is developed on local computer with MSSQL 2005 Express. My host is on MSSQL 2005 workgroup. Are they compatible, because I am getting errors? Is my approach wrong?
I have tried several approaches.
A) I created a backup of database on my local, then placed a copy on the server. Then I tried to restore through Server Management Studio. I get this error.
TITLE: Microsoft SQL Server Management Studio
------------------------------
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

B: I also have tried copying the database. I put it in the same path as the other databases that can be read with server management studio on the server. Then, tried to get to it through server managements studio and it did not appear. So I tried to attach it. Then I received this error:

C: I have also tried opening the Database, and back up file through Server Management Studio. without success.
D: I also tried Windows and Software update at microsoft update, but no updates were recommended for Version on Server.
I'm surprised this is so hard. My original data base was created in same family of software. 2005 MS SQL Express. I could use some direct help from someone experienced with this. Am I doing it wrong or are the DB versions incompatible.

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.

Hello,
I have this problem on a Production database.
DBCC OPENTRAN shows "REPLICATION" on a server that is not configured for replication. The transaction log is almost as large as the database (40GB) with a Simple recovery model. I would like to find out how the log can be truncated in such a situation.
Thank you.

Hello,I'm getting the following error message when I try add a row using aStored Procedure."The identity range managed by replication is full and must be updatedby a replication agent".I read up on the subject and have tried the following solutionsaccording to MSDN without any luck.(http://support.Microsoft.com/kb/304706 )sp_adjustpublisheridentityrange (http://msdn2.microsoft.com/en-us/library/aa239401(SQL.80).aspx ) has no effectFor Testing:I've reloaded everything from scratch, created the pulications from byrunning the sql scripts generated,created replication snapshots andstarted the agents.I've checked the current Identity values in the Agent Table:DBCC CHECKIDENT ('Agent', NORESEED)Checking identity information: current identity value '18606', currentcolumn value '18606'.I check the Table to make sure there will be no conflicts with theprimary key:SELECT AgentID FROM Agent ORDER BY AgentID DESC18603 is the largest AgentID in the table.Using the Table Article Properties in the Publications PropertiesDialog, I can see values of:Range Size at Publisher: 100,000Range Size at Subscribers: 100New range @ percentage: 80In my mind this means that the Publisher will assign a new range whenthe Current Indentity value goes over 80,000?The Identity range for this table cannot be exhausted!

Hi,
I have a VB.net app that access a SQL Express database. I have transactional repliaction set up on a SQL 2000 database (the publisher) and a pull subscription from the VB.net app. I use RMO in the VB app to connect to the publisher. My problem is I am getting some strange behaviour as follows
- if I run the app and invoke the pull subscription it works fine. If I then close my app and go back in, I can access my data without any problem
- If I run the app and try to access data in my SQL Express database it works fine. I can then close the app, reopen it and run the pull subscription it works fine
however.......
- if I run the app, invoke the pull subscription (which runs fine), and then try to access data in my local SQL Express database without firstly closing and reopening the app, I get a login error
- if I run the app, try to access data in my local SQL Express database (which works fine), and then try to run the pull subscription I get a "the process cannot acces the file as it is being used by another process" error. In this case I need to restart the SQL Express service to be able to run replication again.
I get exactly the same behaviour when I use the Windows Sync tool (with my app open at the same time) instead of my RMO code to replicate the data.
I am using standard ADO.Net 2 code to access my SQL Express data in the app and closing all connections etc
Any advice appreciated !
Thanks

Hi all,
I know that adding a column using ALTER TABLE to add a column automatically allows SQLSERVER 2005 to replicate the schema changes to the subscribers, however, I would like to add a new column to an existing article that is being used for merge replication, however, I don't want this column to be replicated. Re-initialising the subscriptions is not a option. Help would be appreciated.
I am using SQLSERVER 2005 (SP1).
