DB Freezes When Replication Agent Cant Deliver
Feb 27, 2004
Hi
We are repeatedly having the trouble of our publisher database becoming unresponsive during network problems.
We have publisher in carribean, distribution agent in canada and subscribers all over. The problem comes when publisher cant deliver to distributor due to network outages.
We are planning on moving the distributor to the carribean ultimately but that will take a while, and our application repeatedly needs to be restarted due to these freezes.
Does anyone know of this problem & possible ways to fix it in the short term (short of changing our replication topology).
is this a bug in replication?
ps.database is merge & transactional pubs. (some tables merge/some trans)
help much apprec,
des

We just moved source server to newer, bigger box ... Windows 2003 and Active Directory ... Snapshot agent worked but distribution failed ... Same login as on older machine, login is sysadm, used DCOMCNFG to allow ability to launch process ... What are we missing?

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.

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

I seem to be having trouble with the distribution agent not doing what I want it to do. I have set up a few publications to run all the time but when I want to schedule a publication to run once a day this doesn't happen it defaults to run all the time.
Can the distrubition agent run some publications continusly and some publications scheduled?
Can anyone shed some light on this problem.

Please, i need some help with the replication i had configured.
I have two publications to the same subscriber, one with data filters and other not.
The one without data filters i have test manualy. But now after i have created the other one, the log reader says that '145 transactions with 347 commands' were delivered, but the distribution agents says that 'no replicated transactions are avaiable'.
I know that have many things to be replicated, but doesn´t work.
The Sql server agent is working on the distributor.
There is something that can be causing this error ?????
Please, if someone can help me i apologize
Thanks in regards

Hello,
What happens to these REPLication agents if SQL Agent is stopped and started:
Snapshot Agents
Merge Agents
Misc Maintenance Agents
Can the agent be stopped and started with no thought to the status of replication, or should the replication state be modified in some way before any change to the status of the Agent?
(I know REPL depends on agent, so wuestion is, can REPL simply resume or not when agent is re-started.)
Thanks.

Hi Guys,
Ive accidently gone and deleted a snapshot agent off a working publication (tables distribution.dbo.mssnapshot_agents, msdb.dbo.sysjobs etc).
Is there a workaround to create a new snapshot agent for the publication without having to break or recreate the publication?
I have tried adding a snapshot and only to fail, can anyone help? thanks a million
---*** Tried adding a snapshot agent ***---
use publishing_database
go
-- Add snapshot job
exec sp_addpublication_snapshot @publication = N'publication_name',
@frequency_type = 4,
@frequency_interval = 1,
@frequency_relative_interval = 1,
@frequency_recurrence_factor = 0,
@frequency_subday = 8,
@frequency_subday_interval = 1,
@active_start_date = 20040101,
@active_end_date = 20040101,
@active_start_time_of_day = 0,
@active_end_time_of_day = 235959
GO
-- RESULT:
Server: Msg 14101, Level 11, State 1, Procedure sp_MSaddpub_snapshot, Line 73
The publication 'publication_name' already has a Snapshot Agent defined.

During testing, the log for tempdb filled up.
That caused the replication agents to get an error and stop.
Is there an easy way to have the agents wait a minute or 2 then try to restart?
Thanks

I seem to have an orphaned Distribution Agent. There is no associated Publication and the agent is sending errors. The errors would be legitimate if only I had an associated publication. I also do not have an associated Snapshot Agent.
How can I get rid of this bogus agent? I already deleted the associated job and rebooted SQL and SQLAgent but it still persists.
Any help would be appreciated.

What does this error message mean ?
The process could not bulk copy out of table '[dbo].[syncobj_0x3732313945323046]'.
I ran transaction replication successfully last night. Then it was scheduled to run again in the morning, but failed .... any ideas ?

I have been seeing this issue for several weeks now. The distribution agent will become idle even though there is activity occurring within the replicated database. If I manually start the distribution agent, it will begin retrieving the transactions. I thought that this might be due to inactivity but I have modified the inactivity threshold and I am not receiving an actual inactive agent warning. There are no warnings -- it simply sits there and does not resume sending transactions.
Any thoughts? This is a transactional replication with a distribution agent that is run at the subscriber.
Thanks,
MV

Hi,For some magical reason, my database replication has suddenly stoppedworking. I modified the publication but the Distribution agent willnot run; the snapshot does not get applied to the subscriber, andchanges made at the publisher do not get replicated.My configuration is: Transactional Replication with a 'Pull'Subscription. The Subscriber is Updateable with Immediate UpdatesOnly. All created via the SQL Server Enterprise Manager. Both thePublisher and Subscriber are on the same server. I'm running SQLServer 2000 (8.00.760 SP3), on Windows 2000 Server (5.0 (2195)).I manually run the snapshop agent. It runs fine with the status'Succeeded' and the Last Action is 'A Snapshot of X article(s) wasgenerated'.When I look at the distribution agent, things start to get a bitconfusing in ( <SERVERNAME>/Replication Monitor/ Publishers/<SERVERNAME?>/ Publication/ Subscription), the status staysconstantly at 'Never Started'. All other columns are either blank or0. When I right click over the subscription, both Start Synchronisingand Stop Synchronising are NOT greyed out. If I click on either StartSynchronising or Stop Synchronising (absolutely) nothing happens(except the mouse turns 'busy' for a fraction of a second). There areno error messages.I added -output c:sqlout.txt -outputverboselevel 3 to thedistribution agent command. C:sqlout.txt did not get created.It worked fine up to a couple of days ago. I'm not sure exactly whatcaused the problem, as I made a few changes at the same time. Thechanges included: adding a new transactional publication, adding morearticles to an existing transaction publication, and adding a mergepublication. I've tried to go back to the set up before I made thechanges, even disabling replication and starting again from scratch.Still the problem persists.The owner of the distribution agent has dbo permissions in both thepublishing and subscribing database. Under 'Publisher and DistributorProperties' I've set the 'Replication Agent Connection to Publisher'and 'Agent Connection to the Subscriber' both to Use SQL ServerAuthentication, both with the same account that has dbo permissions inboth publishing and subscribing database.Has anybody come across this problem before? Can anybody make anysuggestions? Thanks in advance for your help.RegardsDamian HelmeIS ManagerINTEC Engineering (UK) Ltd.

Why would you schedule a Snapshot Agent to run daily, weekly, monthly, etc. for Transactional replication when the transactions are replicated once the change is committed to the Publication database?
Does this help to replicate DDL against the Subscriber?
Thanks,

I can't believe this. MSDE was a great product and I'm sure that SQL Express is even better. The difference is that I can't migrate any of my company's applications to it because they rely on a Replication architecture (requiring Replication Publication). And SQL Agent, how are you supposed to keep the database in good shape if you can't run Maintenance Plans at scheduled intervals?
I know, there are third party products out there to compensate for the lack of the SQL Agent, but they don't solve the replication problem. Besides, the Agent still exists in other editions - it's not like it has been dropped completely. Why do we have to lose functionality and features? We have already lost the use of a second CPU and memory > 1GB. Why do they need to keep taking stuff out? Why don't they just limit access to the new feature-set?
I would rather lose the new features such as Report Server and Full Text Indexing and get the SQL Agent and Replication Publication back. I can almost understand that with a free product, they don't want to keep piliing new features in just to give them away - even though I'm sure the sale of the larger editions more than covers the R&D investment in their construction. Why can't we chose? Agent or Report Server, Replication or Full Text Indexing? I don't need some of these new features (others might), I just want the features that I used to have. Perhaps SQL 2005 setup can be made to choose 2 out of the 4 features?
Whats more, I can't even say that I'll just stick with MSDE, as it now has a limited support life. Microsoft announced that any SQL Server version prior to 2005 SP1 will NOT be supported on Vista or Longhorn Server (nor does it support anything less than Windows 2000 SP4 or Windows XP SP2 where MSDE does).
OK - let me get this right. We had something that has been taken away in the new version. Perhaps I don't deserve the new version if I don't pay for it - fine - I'll stick to the old one I already have. BUT wait... I can't use that on the new platforms coming out.
Are my entry-level customers going to pay for the Workgroup Edition (add AUD$1200 to my entry level edition application of AUD$1500) to replace the Replication Publisher and provide a Maintenance plan? Is anyone going to pay for the re-architecting and re-construction of my application to work around these new limitations?
I guess that will be me. Is this what happens for being loyal to MS products?
Please - give back the SQL Agent and Replication publication.
Joe

Hi There
I have a publisher, remote distributor and subscriber all running SS2000.
Under replication monitor on the distributor, under replication alerts i have enabled the "replication agent failure" alert.
All i need to know is should this alert trigger if the distribution agent that runs on the subscriber not the distributor fails?
I have add occurences of the distribution agent failing and the alert is not triggerred, is this because it only triggers for the agents that run on the distributor, ie: snapshot and log reader agents?
Thanx

I have asked this question before (but the question was geared for something else). Let me briefly lay out my question.
I currently have a WinForm app I distribute that interfaces with Access. When I distribute it, I have in the application startup path a folder called "Database" which has the Access .mdf. With me so far?
Now.
I have tools that automate and semi-automate the embedding of important information into my database during the course of a project. However, because more people are starting to use my tools, we have a concurrency issue. I was looking at SSEE as a replacement for Access to solve this problem and avoid the concurrency problem. Hence it is not for the customer I am moving to SSEE but for my internal team who use my tools.
I am having a difficult time delivering the finished product because I don't quite know how to deliver SSEE. I am very proficient with setups, and know that as a prequisite they have SSEE as a selectable item, but how to I attach my database to SSEE in the setup? Do I need to detach my database from my server and reattach it during the setup for the customer?
I have found no articles describing this (except ClickOnce which is not what I want). If everyone raves about SSEE over Access, I would think this would be a widely available question.
This is probably a question for a MVP or someone who has dealt with this personally, so I would welcome your expertise in this matter.
Thanks

Hi,
I am trying to replicate a merge replication between two databases for 2 SQL Server 7 SP2 on Windows NT sp6a. I make a publication for my Server1 and set the properties for the publication (Choose Server1 as the Distributor, Merge publication, all subscribers will be running SQl Server etc, Publish All Data, No filter...blablabla finish).
The problem is that the SnapShot Agent firstly prepares all tables for Merge Replication in status of Snapshot ("Preparing table '[dbo].[Table]' for merge Replication") ... SQL Server Snapshot Agent expired when it arrives at a table which has 1,800,000 records.... it's a very important table for my business after having made the majority of it before. Following this error, it starts again, and always starts again while being expired and returned with this table.
Is it that the SnapshotAgent has a limit for Records? What can I look at to correct the problem.
Any help appreciated,

We have transactional replication publications from SQL 2014 to SQL 20122008 R2. When we add new tables to the existing publication and start the snapshot agent, Snapshot agent updates the statistics for random tables on the publisher DB. It appears that all the outdated statistics are being updated regardless which table is being initiated. In a highly transactional environment we can't update the statistics every time. its causing huge issues for us. Is there any work around for this ?Â

i am having a problem with the merge replication.
has over 400 thousand records and is running on a hp server with a raid 5 configuration.
i am trying to create a merge replication on another server with the same configuration.
i am facing problems in 2 places.
firstly i created a push subscription and ran the snap shot agnt.
but the snap shot agent times out and expires .. as a result of which i am not able to create the initial snap shot on the subscribers end.
next i thought i would manualy create a snap shot
and so i backed up the dabase from the publisher and restores it on the subscription side.
now i tried to create a new subscription by chosing the option... the dabase alredy conists of the data base and schema
and i get a n error saying
"SQL Server Enterprise Manager encountered errors creating push subscriptions for the following Subscribers:
ICE: Error 20086: Publication '%s' does not support the nosync type because it contains a table that does not have a rowguidcol column
what do i do to solve this problem....
please try and give me a solution to solve either ways.
thanks,

Is there a way to force the snapshot to use a format file when bcp'ng the data to the subscriber?
The publisher and subscriber schemas are slightly different. Mainly added columns to the subscriber.
We have a post snapshot script that updates these additional columns on the subscriber.
I'd like to force the snapshot to use a format file, so it doesn't error when initially loading the data to the subscriber.
Is this possible?

I'm trying to setup merge replication and get the following error from the snapshot agent after I've finished the 'New Publication Wizard'. This doesn't make sense to me as it is an automatic process. Also, it looks like it is complaining about a 'dbo.MSmerge_cont...' view which is a view created automatically for the merge publication.
