Distribution Agent Basics?
Nov 6, 2006
Hey everyone,
sorry for the lame questions, but:
1) I have a transactional replication service set up. However, whenever we select a new table or column within a table to replication to the subscribers, the changes never seem to get picked up unless we make an actual change within some of the other data. Any idea why this is? Even after I've reinitialized snapshots, the new changes don't want to proprogate to teh subscribers until data is actually changed.
2) where do I need to go to manually stop and restart a a distribution agent to force these changes to be proprogated without having to change any data within the tables?
Thanks

HI,
We are having a problem with a distribution for a publication.
It is replicating email field and one of the values had a ' in it which is failing at destination.
Is there a way to get rid of this bad record from distribution agent cue?

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

Maybe I'm just totally not getting it, but can someone tell me how to stop/start the distribution agent? The Books Online document - "How to: Start and Stop a Replication Agent (SQL Server Management Studio)" - shows how to stop/start the Snapshot Agent, Log Reader Agent and Queue Reader Agent, but not the Distribution Agent. Is it that stopping one of these agents in turn stops the Distribution Agent. I am trying to work through how to add an article to a peer-to-peer topology and need to stop the agent as part of that.
Thanks,
Larry

Can anyone help me on this??
I have a transactional replication going on from Server A to server B (Sql Server 2005)
The replication was working well till yesterday..
But now, the replicated transactions are not getting applied at the subscriber. When I see the Log reader agent, its working fine...delivering the transactions to the distributor. When I see the replication monitor status ..it says 'delivering replicated transactions'...however the number of undistriuted transactions is very high..its getting bigger and bigger..not decreasing...I dont see any errors..So my guess is the distribution agent is not working eventhough its says 'delivering replicated transactions'..Other thing is if i see the replication monitor it says status excellent...and latency as 00 ..but i dont see the latest data at the subscriber..the subscriber is way behind the publisher..
can anyone help me on this?? how do i resolve this problem??? I stopped the distribution agent and again started it..but it dint help...what should i do??
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.

I have a replication Push Subscription configured that works most of the time but I get occasional errors satating that "The process could not connect to the Subscripber 'xxxx'". The details are
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
(Source: PYRRXNDAL341WIN (Data source); Error number: 18452)
This happens randomly and when it does fail, I can either what for the next occurence in the schedule or I can start the agent manually and it completes successfully. I can also ping the other box when it happens. I've looked at the event logs and don't see anything going on around the times the distribution agent is having the problems.
Any suggestions on where to start looking for more detail?

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.

Hi,
I am trying implement replication and having problem when creating push subscription to an existing transactional replication publication.
The distribution agent is failing to run its job with the error:
Agent message code 14260. You do not have sufficient permission to run this command. Contact your system administrator.
I followed the http://msdn2.microsoft.com/en-us/library/ms151868.aspx article instructions when I set the distribution agent properties
What did I miss?
The following is the step error message:

Replication Distribution Agent often dies with the following log entry. At that hour little is ever going on so I am surprised that the error occurs.
Failed Job -> JobName: Instance1-DB1-Instance2-33, StepName: Run agent., Message: Timeout expired. NOTE: The step was retried the requested number of times (10) without succeeding. The step failed..
Any ideas where to start?
Thanks

Hi,
We have 32 individual publications setup on SQL 2000 and have 32 distribution agent running against it. I think each distribution agent opens a process called distrib.exe in Windows task Mgr.
Problem I'm having is that these 32 distribution agents are taking up fair amount of memory 1/2 gig and each process seem to be ever increasing in memory usage so I suspect a memory leak?
Is there something I can do to fix this problem? I don't want to upgrade memory as we already have over 1 1/2 gigs on this machine and it would not be feasible if we have a memory leak.
thanks!

We have quite a lot of Transactional replication, and over the past few weeks it had become quite slow. I spent the last few days trying to resolve the problem and found that a Push subscription was delivering transactions at about 50/sec and a Pull subscription was delivering at around 700/sec.
This test was run on the Same publication, same subscriber so hardware and links are all the same, the only difference was the type of subscription. I've since changed a few of our subscriptions for the larger publications and have found they run quicker than previously.
Has anyone else seen this behavour and is there a valid reason why this would occur. The distributor and subscriber are both running SQL2005 SP1 and the publisher is SQL2000 SP4.
If anyone could shed some light on this it would be appreciated.

I've been using replication for a long while now but have never come across this error. It's a basic transactional replication from ServerA to ServerB, where ServerA is also the distributor. Everything had been running fine on it until yesterday, when this error started popping up and no further transactions could be delivered.
After some quick googling I was able to determine that the distribution agent account needed write access to C:Program FilesMicrosoft SQL Server100Com. According to the MSFT article it's because the distribution agent is running under a non-default profile. I didn't change this. However, what I did change around the time that these errors started occurring was the server's Replication Max Test Size setting. It would be far too coincidental for this to not be the cause, but what I don't understand is *why* that would have changed it.
how do I change this? It is definitely not preferable to create temp files in this directory in our environment.

Hi,
We have replication setup on a sql server 2000. We encountered issue that the distribution agent goes down (distrib.exe stop running) in the event of network connection broken. We would like to know:
is this the expected result that the distribution agent will go down in the event of communication failure between the distribution server and subscriber server?
if not, is there a way to programmatically control and restart the agent?
Is there any sp in SQL server which can monitor the replication communication error message?
is there any sp in SQL server which can be run to restart the agent?
For the best practice, what do you think we can do to achieve an €˜event-driven€™ kind of mechanism so when an communication breaks, the agent can be restarted by the triggered event (or at least a simple way to automatically restart)?
Thanks
Bill

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.

On SQL Server 2005 SP2 for Publisher and Distributor on the same instance, my old snapshots are not being cleaned up.
The following error is in the agent history:
Executed as user: DomainMyUser. Could not remove directory '\vmsql01ReplDatauncPublication_TRANSACTIONAL20070702104416'. Check the security context of xp_cmdshell and close other processes that may be accessing the directory. [SQLSTATE 42000] (Error 20015). The step failed.
xp_cmdshell is enabled and I can run commands like :
exec master.dbo.xp_cmdshell ' md c:TestFolder'
The permissions to the snapshot share and file system are that DomainMyUser has full control.
I have logged into the machine as this user and can remove snapshots so it does not seem to be a permission issue.
On other machines I do not get any errors but the snapshot folder still is not cleaned up.
Any suggestion as to what the problem could be?
Thanks,
Amy

I've a number of SQL DBs that are managed by a php browser front end. These were developed in php/html to a SQL 2000 DB.
The DB and tables have been recreated in SQL 2005, permissions are that of the owner (SA) and the php code has been adjusted accordingly. Although the reading of the data is okay, I cannot update nor insert data from the php script through to the SQL 2005 DB whereas it works perfectly fine through the same php script and SQL 2000.
Obviously, there's something I'm not seeing??? There are no noticable messages and the last transaction does show up in the php display.... closing the portal then reopening, the record is "gone" and the SQL 2005 DB remains untouched.

Hiya,
I've recently gotten into the administration side of SQL and am muddling my way through it as best I can. We have a DB server with three or four databases on it. Maintenance routines do a full backup of each one nightly and weekly and put all sets into one backup (.bak) file.
I've never had to restore them, but I thought I'd put myself through a test run since this is unexplored territory for me and I would prefer not to have to learn in an emergency.
A scenario I can foresee is where I'd have to restore just one table, perhaps to a new location (i.e. not overwrite the live db, just bring up a copy of part of it elsewhere so I can do a data dump from some old data). But when I go to 'restore database' or 'restore file/filegroups' and select the file, it seems to really want to restore the full backup directly over top of the existing database. If I try to restore it to a new, non-existent database, I get an error about how 'logical file master is not a part of database 'new-backup'), and if I try to restore it to a new db that I've created, I get an error about how the databases don't match.
It seems to me that my problem is a philosophical one - perhaps I don't understand the nature of backups, but I feel like what I'm trying to do is pretty simple. I want to take the full backup of database A and restore it, in part (or in full if I have to) to new database B. What do I need to do to accomplish this?
Thanks for indulging me - this must be brain-dead stuff for most of you!

Hi there, I'm still fairly new to asp.net / c#
I've setup my stored procedure, but now what?
I want to display the information (only one record it will return) on the page / NOT using a datagrid or list, just simple.....I guess using an asp:label?????
Could someone tell me what I need to do!!!
Also, are there any proper resources out there that just show you right out of the box howto insert / update / delete with sp's?, show / view, just proper simple source code?
THANKS!
my code:
// Creating the database connection
SqlConnection objConn = new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["MM_CONNECTION_STRING_conn_main"]);
// Creating the stored procedure 4 the webpage
// Instantiate a Sql Command
SqlCommand webpage_view = new SqlCommand("stpr_webpage_view", objConn);
// Declare that the T-SQL statement that will be executed is a stored procedure
// Use a CommandType.Text to execute a T-SQL Query
webpage_view.CommandType = CommandType.StoredProcedure;
SqlParameter webpage_id_parm = webpage_view.Parameters.Add("@webpage_id", SqlDbType.Int);
webpage_id_parm.Value = "1";
// Create a SqlDataAdapter to manage the connection and retrieve the data
SqlDataAdapter da_1 = new SqlDataAdapter();
// Instantiate a Dataset that will hold the data retrieved from the database using the select command
DataSet ds_webpage = new DataSet();
da_1.SelectCommand = webpage_view;
// Retrieve the data into the dataset using the SqlDataAdapter.Fill command
da_1.Fill( ds_webpage, "webpage_title" );
DataView dv2 = ds_webpage.Tables[0].DefaultView;
if ( !this.IsPostBack ) {
this.DataBind ( );
