Does Replication Affect Tempdb GROWTH Replication
Jun 28, 2007
Hi all,
I have recently setup a transactional replication in MS SQL 2000. After setting up the replication the clients TempDB grew by almost 60GB. Now the client is Blaming me for the TempDB GROWTH and saying that its because of the replication being setup i tried to convince them but they are not satisfied yet. Can anybody please tell me does replication cause the tempdb to grow. If yes then how. can u suggest any good link for getting to know the internal working of SQL Server replication????
Thanks in advance

Suppose your using Merge Replication.
2 Users in 2 locations issue updates to the same table. 1 updating 1 column and the other updating another column. Now in reality the actual Stored Procedure issuing the update statement is passed in all the possible columns that could change and builds an update statement that updates all columns even the ones that havent changed.
Will this break Merge Replications conflict tracking? Or does SQL Server 2005 Merge Replication pickup that in reality the 2 updates only in reality changed the values in 2 columns.

I am getting the error The transaction log for database 'ReplicationDB' is full due to 'LOG_BACKUP'.log_reuse_wait_desc from sys.databases is showing logbackup
The database is subscribed database. We configured transactional replication. But the transactional replication is getting errors and failed. Is there relation b/n this replication failures and log growth in subscriber db?

We think we're having performance problems, and among the areas of investigations is the tempdb database. Since it resets itself after SQL is restarted, is there a way to find out how big it has grown in the past ? Does leaving it at the default size cause a performace hit ?? Right now it's 8.75 MB, with 7.38 MB available, which sounds pretty harmless.
Any thoughts ?

Could a simple update statement on a user database ever caused space usage in tempdb? Assuming the update statement fires no triggers and not using any temp tables?
IE:
User DatabaseA
Update TableX
Set col1 = X
Reason I ask is tempdb filled up and the only thing I could see running at that time was the update statement.

I am having a problem with the growth of the tempdb on my SQL 7.0 box. I have over 300+ stored procedures that are running (many with group by and order by in them). This is causing the size of my tempdb to grow to over 30gigs in size. If i reset the services of the DB it shrinks back down to the managable 6 gigs that i expect. Is there a way to have the services restart automatically on a nightly basis or is there a way to have the tempdb deallocate resources once they are used without restarting services?
I apreciate any help you can provide,
Nathan

Iam close to Production on our new SQL Server Environment.
How do u typically manage Disk Space (Particularly tempdb)
-Would you have a Job to run during Non Usage Hours to Shrink the Tempdb?
OR
-Would you have the Autoshrink ON?
What is the best approach?

We have a problem with the size of the tempdb.mdf file. The tempdb had grown to 25Gb and consumed all the available disk space. SQL server was restarted and the tempdb was reset back to the default size. The following day the tempdb suddenly increased in size from 200mb to 25GB within a very short space of time. There were a couple of event log entries from sqlservger regarding the lack of disk. Since then the server is running without any problems but the level of free space is virtually zero on the drive with tempdb.mdf file.
What would cause the tempdb to grow suddenly and to this size?
Can I control the size the tempdb can grow to?

I'm getting this, after upgrading from 2000 to 2005.Replication-Replication Distribution Subsystem: agent (null) failed.The subscription to publication '(null)' has expired or does notexist.The only suggestions I've seen are to dump all subscriptions. Sincewe have several dozen publications to several servers, is there adecent way to script it all out, if that's the only suggestion?Thanks in advance.

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! I'm not surewhat to try next.Please! any insight will be of great help!Regards,Bm

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
Ronan

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).

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.

Hello everyone,I am involved in a scenario where there is a huge (SQL Server 2005)production database containing tables that are updated multiple timesper second. End-user reports need to be generated against the data inthis database, and so the powers-that-be came to the conclusion that areporting database is necessary in order to offload report processingfrom production; of course, this means that data will have to bereplicated to the reporting database. However, we do not need all ofthe data in the production database, and perhaps a filtering criteriacan be established where only certain rows are replicated over to thereporting database as they're inserted (and possibly updated/deleted).The current though process is that the programmers designing thequeries/reports will know exactly what data they need from productionand be able to modify the replication criteria as needed. For example,programmer A might write a report where the data he needs can beexpressed in a simple replication criteria for table T where column X= "WOOD" and column Y = "MAHOGANY". Programmer B might come along amonth later and write a report whose relies on the same table T wherecolumn X = "METAL" and column Z in (12, 24, 36). Programmer B willhave to modify Programmer A's replication criteria in such a way as toaccomodate both reports, in this case something like "Copy rows fromtable T where (col X = "WOOD" and col Y = "MAHOGANY") or (col X ="METAL" and col Z in (12, 24, 36))". The example I gave is reallytrivial of course but is sufficient to give you an idea of what thecurrent thought-process is.I assume that this is a requirement that many of you may haveencountered in the past and I am wondering what solutions you wereable to come up with. Personally, I believe that the above method isprone to error (in this case the use of triggers to specifyreplication criteria) and I'd much rather use replication services tocopy tables in their entirety. However, this does not seem to be anoption in my case due to the sheer size of certain tables. Is thereanything out there that performs replication based on complexprogrammer defined criteria? Are triggers a viable alternative? Anyalternative out-of-the-box solutions?Any feedback would be appreciated.Regards!Anthony

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...

I have a wired situation..!I set up transactional replication on one of my development server (SQL2000 Dev Edition with sp4).It is running fine without any issues and all of a sudden, i noticed inmy repication monitor tab under Publisher where I usually see thepublication is empty now.I do see the snapshot agent, log reader and distribution agent under myagents inside the replication Monitor. But its usefull to see all 3agents in one window under publisher before. What happend? Is there anyway to get that inside that monitor? Has someone encountered thissitation before? Please advise....After that I tried to create a new set of replication on differentdatabase on the same server and i dont see those either underReplication Monitor - Publishers....All it says is (No Items)....I would appreciate any help to correct this issue... Thanks in advance..

Hi,
I have a particularly difficult problem.
I have a SQL Server in an internal network and need to "replicate" to an identical server and database in a DMZ. The DMZ can only receive files sent by a custom component and no port(s) can be opened in the firewall or standard FTP used.
I also need to minimise traffic (i.e. sending whole tables is not an issue as some contain millions of rows), replicate approx once hourly and allow record locking only (as opposed to DB locking/exclsuive access or table locking).
Any thoughts / experiences greatly appreciated otherwise I'm looking at putting triggers on all the tables to monitor changes and generate SQL statements for execution against the DMZ server.

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

I was working on a project that use local and remote SQL server. In order to keep the database up-to-date I wanted to implement replication on the SQL servers. But unfortunately the transaction replication which meet my requirement best is disabled on the replication configuration module (snapshoot and merge replications are active). Is there any way I can make the transaction replication enabled. I know it was supposed to be enabled by default. I’m using Windows 2003 server and SQL server 2000. Sincerely

I have a failry complicated problem, or at least I think its complicated.
I'm working with a database that is not very normalized, and I was asked to make a portion of the dataset it available to web users.
Rather than build a complicated mess on top of the existing database, I opted to create an entirey new database inspired by the original, only normalize the data. So, where I had 3 tables in the old system..I now have around 10 nice and neat normalized tables.
Now the trick is to get the data from the original database to the new one. I could write my own application to do this, but I wasn;t sure if SQL's built in replication would be of any help.
I think I'm a little bit confused because thetwo DB schemas are very different from one another, and I'm not sure if built in Replication can work with this sort of set up.
Luckicly, the replication pretty much on needs to go one way, from the original database to the new one. The original databse will still be in use, but for the most part only insert will be happening there, and a few updates. In the new database, there will be no inserts, but there will be updates, and they don't have to be replicated back to the original DB. So, that seems pretty easy to me.
If I were to use replication rather than write my own tool to sync up the data, how woudl I go about this, and is it even possible?
One thing I thought of was was creating a bunch of views in the original database, that looked just like the tables in the new system..and having replicaiton work with those...the only downside I see is the views will have no relationships, and in the new DB all the tables have valid relationships..so I may run into situations where child records are getting replication before parant records..and that will cause issues.
Any advice would be helpful. Thanks guys!

I am in the process of setting up replication from SQL2k to 6.5.
Both server have mixed authentication and are using the same login
that has domain rights and is a local admin on each box.
However, repliation fails with this error message;
Login failed- User: Reason: Not associated with a trusted SQL Server connection.
I have tried searching this site, BOL and other newgroups sites for
a step by step guide to setting up replication, but am unable to find anything.
Anyone have any suggestions ?
Please advise
