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,

When you create a transactional Replication.Is there a way to disable to snapshot agent scheduler. I believe that there is a way to disble it when you create a publisher.
Help ME!!!!!!!!!!!!!!!
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've set up Transactional replication Pushed from SQL 7 to SQL 2000. All works fine accept I have noticed that the snapshot agent is running once a week and storing a lot of data I don't really need in c:msql7
epldataunc
eplicationnamedatastamp. This is gradually building up and as C is a smallish partition it'll only survive for another week.
My questions are:
1) Can the Snapshot schedule be disabled? I'm under the impression that it's only required when a new subscriber comes along which is never! If I do need a new subscriber I could just manually produce another snapshot.
2) Can I delete the previous snapshot folders under ReplData? On a development server I renamed one of the folders and the ground didn't open up below my feet.
3) What effect would changing the working folder used by the distribution agen have, the distributer is on the publisher (which as I mentioned is pushing) I've tried changing the working folder, on a development server, I manually ran a snapshot which whose BCP files all ended up in my new location and the Transactional Replication didn't seem to care.
I've looked in a few places for a difinitive answer and I'm not having much luck so any help (preferably before saturday) would be greatly appreciated.
Regards.
Hi
I am in the process of setting up replication between two SQL boxes - the first being the production SQL Server and the second being a secondary server which is to be used as part of a web portal solution. (In fact there are two pairs of SQL boxes - SQL 7 and SQL 2k, one of each on the LAN and one of each at the hosting site.)
We need to have near realtime replication, so transactional replication is the desired mechanism. The trouble is that not all tables have primary keys defined. Oh yes, and the main database is 20G in size and has >900 user tables! :-0 (The other databases are much better behaved!)
When I set up transactional replication, I am allowed only to include tables which have PKs defined. AFAIK, the initial transactional replication snapshot will also only include these same tables.
If I set up snapshot replication (separately), I can include all the tables in the database. However, I cannot then replicate in real time.
Can I combine the two replication schemes to deliver updates to the same target database:
- transactional replication delivering realtime updates to the tables with PKs during the day and
- snapshot replication updating all the tables once per 24hrs at night?
Or is there a better way of doing this?
I am not sure whether I can modify the existing schemas, as some of the databases are 'maintained' by an external provider. Even if I could, if I had to add a column to have a PK, I would potentially be adding to my diskspace requirement rather significantly...
TIA
Hello,
We are running transactional replication in a high volume environment and we are starting to see high IO on the distribution database when the distribution cleanup runs. We only build the snapshot once a week and I was wondering if I rebuilt the snapshot more often it would reduce the size of the distribution database and the amount of IO that are being generated during the cleanup?
Thanks in advance
Hi,
I have transactional replication setup with SQL 2000 on W2K3 cluster using updateable push subscribers. While setting up replication, we chose default location for snapshot folder that resides on non-clustered drive. Is there a way to change this location without disturbing current replication setup. I looked at the 'alternate snapshot location' solution, but it requires snapshot re-initialization. I am trying to do this with minimal effort and downtime.
Thanks,

I have transactional replication running. I would like the Snapshot Agent to run regularly (once per day, probably, at 23:00) so that the target data are completely refreshed so that there is little possibility of the target getting out of sync.
The Snapshot Agent's job is kicking off OK, but the "snapshot was not generated because no subscriptions needed initialization". I know I can initialise the subscriptions manually - is there a way to do this so that the initialisation happens just before the snapshot job launches?
Or is this a bad thing to want to do?
TIA
SQL Server 2005 Books Online provides an article entitled, "Initializing a Transactional Subscription without a Snapshot". Is it possible in SQL Server 2000 to initialize transactional replication without a snapshot?
So far, I have been unable to find a similar procedure mentioned in the SQL 2000 Books Online. I was able to follow the 2005 procedure using SQL 2000 until I got to the step that says to enable the "Allow initialization from backup files" option on the "Subscription Options" tab of the "Publication Properties" dialog. But that option does not appear in the SQL 2000 version of the specified dialog box.
Any ideas?
I have a pretty big (350 gb) OLTP database that I want to replicate in its entirety. I'm concerned about the impact of taking a snapshot of it (it is processing at some level pretty much 24x7). I know on SQL2005 there is the option to initialize from backup, but unfortunately we won't be on 2005 in time.
I'm thinking of doing something like this:
Set up the distributor, publication, and subscription
Turn off distribution agent
Set the publisher to "sync with backup"
Backup the publisher, full then log
Truncate tables MSrepl_transactions and MSrepl_commands in the distribution db (I don't have any other replication going on)
Turn off "sync with backup"
Restore the full and tran log backups to new subscriber db
Create subscriber stored procs in subscriber
Start up distribution agent
I'm looking for opinions on whether it's worth going this route to avoid taking the snapshot. Data integrity is the number one priority -- if I have to do a snapshot to ensure that, I will do it.
Thanks in advance!

I built a number of publications on a SQL Server 2005 box to replicate to a SQL Server 2012 subscriber. All the publications except one are fine. During the snapshot phase of schema script generation I get Script Failed for Table 'dbo.MediaDisplayLibraryFileData'. From the Replication monitor for the Snapshot Agent on the Publication I get, "Column FileData in object MediaDisplayLibraryFileData contains type VarBinaryMax, which is not supported in the target server version, SQL Server 2000." This message makes no sense since the target server version is 2012. I have even checked that the compatibility level was set to 110 before I started the process of setting up replication. How do I resolve this error?
View 0 Replies View RelatedWe have a large database with a small number of large tables in it (and a larger number of SMALLER tables), and it is a publisher for a transactional replication scenario. When I create a snapshot to initialize a new subscription, I notice with the larger tables that sometimes it generates multiple files in the snapshot folder, usually in multiples of 16, and numbers them like this:
MyTable_3#1.bcp
MyTable_3#2.bcp
...
MyTable_3#16.bcp
With other tables, I'll get just one LARGE snapshot file, named:
MyOtherTable_4.bcp
In the latter case, the file can be very large (most recent is 38GB).
In both cases, the subscription will eventually be initialized, but the smaller files will generate separate log entries every few minutes in the Replication Monitor, showing 'Bulk Copied data into 'MyTable' (34231221 rows)', whereas the larger table will generate only ONE log entry, showing 'Bulk coping data into table 'MyOtherTable', and it may take a couple of hours before there is anything else showing...except for an entry saying, 'The process is running and is waiting for a response from the server.'
My question is: what would be the difference between the two tables that would result in one generating MULTIPLE snapshot files, the other only a single, much larger one? The only difference I can see in the table definition is that the one generating multiple files has a clustered index, whereas the others do not.

Hi
We have setup transactional replication between 2 databases on SQL Server 2000 SP3a (~70GB), using a concurrent snapshot (to prevent locking out of the live database) to initilaise the data and a pull subscription from the second database.
From analysing the msdistribution_history table in the distribution database on the subscriber it appears that the snapshot is being applied in a continuous loop to the subscriber database. Viewing the comments column in the msdistribution_history table we can see the following sequence of events occuring
Initialising
Applied script 'snapshot.pre'
Then it applies all the schema files .sch
Then it applies all the index files .idx
The it bulk copies the data in (bcp)
Then it creates the Primary Keys
Then it applies all the trigger files .trg
Then it applies all the referential integrity files .dri
These all complete successfully but then the process kicks off again immediately after reapplying the snapshot. We are unaware of any settings that may be causing this.
Any help on what maybe causing this would be much appreciated.
There is a SQL Server 2008 R2 SP3 Clustered Instance that has Transactional Replication. It is by no means a large replication setup in terms of data/article count. SQL Server was recently patched to SP3 and is current on Windows 2008 R2 Patches.
When I added a new article to replication (via 2014 SSMS GUI) it seems to add everything correctly (replication tables/procs show the new article as part of the publication).
The Publication is set to allow the snapshot to generate for just new articles (setting immediate_sync & allow_anonymous to false).
When the snapshot agent is run, it runs without error and claims to have generated a snapshot of 1 article. However the snapshot folder only contains a folder for the instance (that does have the modified time of the snapshot agent execution) and none of the regular bcp/schema files.
The tables never make it to the subscribers and replication continues on without error for the existing articles. No agents produce any errors and running the snapshot agent w/ verbose output provides no errors or insight into any possible issues.
I have tried:
- dropping/re-adding the article in question.
- Setting up a new Snapshot Folder
- Validated all the settings and configurations
I'm hesitant to reinitialize a subscriber since I am not confident a snapshot can be generated. Also wondering if this is related to the SP3 Upgrade, every few months new articles are added to the publication and this is the first time since the upgrade to SP3 that it has been done.
Unable to start log reader agent after being manually stopped.
Any ideas.
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 ?

Hi,
I have more than 80 databases on my publisher (SQL Server 2000 SP4), I tried to enable Transaction Replication on all of those databases instantly through some T-SQL programming and DTS Packages. Every thing works fine until the snapshot agents starts to take sanpshot from the publisher databases. As soon as their snapshot agents start for those 80 databases, they start giving the deadlock error. All 80 snapshot agents starts at the same time.
Error Message:
Transaction (Process ID xxx) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

WHY???
Hi All,
I would appreciate any help here at all. I am pulling my hair out!
I am unable to start the snapshot agent or log reader agent from within SQL management studio. it fails on executing step 2 with unknown username or bad password.
I have checked all account details and they are correctly using my domain admin account. I can connect to SQL using teh same account and it also has sysadmin permissions.
If i copy the step 2 paramters and start from the cmd prompt (again logged in using the same domain account) they both start fine.
Any ideas would be gratefully received.
I am testing peer to peer replication in our environment. I simulated a three node peer to peer topology and a local distributor.
For some wierd reason I cannot get the Log Reader Agent and snapshot agent to start. The domain account under which SQL Server Agent runs has administrator previlage on the box. I also use a domain account for SQL Server Service. (none of the passwords changed).
This is the error I am getting - "Executed as user: abc. A required privilege is not held by the client. The step failed"
Any ideas???
Also this domain account is a member of
SQLServer2005MSSQLUsers$ServerName$MSSQLSERVER
SQLServer2005MSAgentUser$ServerName$MSSQLSERVER
I am very new to SQL coming from a SAS background.
I work at a College where I am trying to create a table that basically stores application data so that I can record how many applications we had on a set day.
For example I want to run it say bi-weekly and create a date/time stamp for each row and then the next time it runs it appends to the original table but with the new date/time stamp.
I have managed to create the table and the date/time stamp but I'm not sure how to do the next stage.
This is not the best practice as the table will get "big" quite quickly (although we're only dealing in the hundreds in terms of rows). Ideally I'd have a more transactional database that only appends a record if there is a change i.e. the status of the application has changed from "Received" to "Interview" or similar.
I'm not sure how to copy and paste the code dynamically in this forum but this is what I have got so far (see below).
SELECT
CC.cc_name as Academy,
SUBSTRING(CC2.cc_reference,1,4) as Cost_Centre,
MD2.m_reference as Course,
MD2.m_name as Course_Name,
CAST(MD2.m_start AS DATE) as Start_Date,
[Code] ...
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

Hello,
I need to run the sql server snapshot agent from within my c#.net 1.0 code. Regards
Hi, I was wondering if changing the schedule of the snapshot agent will do any effect the unc/snapshot files ? I'm now doing merge replication and i am applying snapshot from alternate location. If i change the schedule do i need to re run the snapshot agent ? I'm afraid that the current snapshot will be expired..
View 1 Replies View RelatedHi guys,
I'm trying to set up merge replication between a SQL Server 2000 SP4 / Win2k box and a MSDE SP4/WinXP box and I'm finding that the initial snapshot isn't being produced.
The SQL Agent runs as a windows user that has admin privileges, the snapshot agent impersonates the SQL Agent. The SQL Server login for the agent account has the server role "System Administrators" and database access to all db's.
When I turn on logging and try to start the agent, the following is written to the log:
Microsoft SQL Server Snapshot Agent 8.00.760

ErrorText = Login failed for user 'SVRNameSQLAgent'.
The process could not connect to Distributor 'SVRName'.
Most of the posts I've seen regarding problems like this are due to subscriber authentication issues (not up to that, this is the initial snapshot) or windows/domain user permissions.
Any ideas what else it might be?
