Replication With Fifteen Subscriptions
Apr 5, 2006
I have recently deployed a sql replication system into a production environment and I€™m experiencing a few problems.
I have a server holding consolidated data (4 processor/2GB ram) and fifteen subscribers, each being a 400Mhz Celeron with 256MB ram.
Transactional replication is used to pull base data from the main server to the subscribers. This data does not change very often at the publisher, but the subscribers need an immediate update, so continuous transactional replication is configured at the subscribers. This data will never be changed at the subscriber.
The server has another three tables used for historical data. Each subscriber has been configured for merge replication on these three articles. An initial snapshot is run to setup each subscriber. Each subscriber writes up to 10 records per minute into these local tables and continuous merge replication replicates these 10 records from the subscriber to the publisher. As all subscribers are doing the same, part of the merge operation will potentially bring down 140 records to each subscriber (10 records from each subscriber merged to the publisher and back to each subscriber).
Anyway on to the problem€¦
Each subscriber system has a Microsoft.Net application writing these 10 records per minute to the local database. Refreshing a graph within the application occurs once every minute. Refreshing, queries the three local tables used for the merge replication. This application shows an error (randomly) with a sql timeout message trying to get a connection to the local database.
Has anybody got any ideas why this will occur?

Hi everybody, I'm quite new to SQL 2005 and I€™m trying to understand some key concepts regarding replicas. I need to develop an application with characteristics similar to the Sales Order Sample for Merge Replication, on the client side it should run with the express version of sql server and also the synchronization should only work via web. I try to run the sample but I got an exception in the CreateSubscription method on invoking publisherConn.Connect();
TITLE: Microsoft.SqlServer.ConnectionInfo
------------------------------
Failed to connect to server XXX.
------------------------------
ADDITIONAL INFORMATION:
Login failed for user ''. The user is not associated with a trusted SQL Server connection. (Microsoft SQL Server, Error: 18452)
I can€™t understand how this connection could work if it isn€™t aware of the fact that it should use https to connect with the server.
Can someone point me in the right direction?
Thanks
Angelo

I have been trying to set up replication with updateable subscriptions. I first followed the tutorial on MSDN and set up basic transactional replication. This all worked fine. I then tried, using that tutorial as a basis, to set up replication with updatable subscriptions.
On the Agent Security page you are asked for a Snapshot Agent, a Log Reader Agent and a Queue Reader Agent. I assigned these to the following accounts, which I created and added as logins, PUBLISHERSERVER
epl_snapshot, PUBLISHERSERVER
epl_logreader and PUBLISHERSERVER
epl_queuereader.
I then tried to set up a subscriber on SUBSCRIBERSERVER. Under the publication I add new subscriber, select the publisher, add SUBSCRIBERSERVER as the new SQL server Subscriber. In the Distribution Agent Security page of the wizard it asks for process account, which will be run when synchronizing the subscription. I entered PUBLISHERSERVER
epl_distribution here and selected the other two default options of connecting to the distributor and subscriber by impersonating the process account. I then took the default options for the next few screens and finally get to:
Login for updateable subscriptions. This offers the option of a login or using a linked server. I have tried various logins here, initially trying the €˜sa€™ login and password. This produced the error: The user is not associated with a trusted SQL Server connection. The servers are set up for mixed mode operation. I then tried PUBLISHERSERVER
epl_distribution and subsequently every other account I had created on PUBLISHERSERVER. All of these failed. I tried linking the servers, but this also failed. How exactly do you set up subscriber with the ability to login to the publisher? I have spent days trying to set this up, and am as you can gather new to this technology, any help would be greatly appreciated.

If I have one table in one publication in transactional replication
replication between primary and replicate is broken because subscription is marked as inactive.
If there are 3 rows on replicate and 5 rows on primary , out of which 2 are added after replication is broken
If I do
Reinitialize subscriptions
start the snapshot agent
start the distribution agent
Does this mean that it will only transfer the new 2 rows to replicate sites ? or will it drop everything from replicate site and apply all rows from primary site on to replicate.
Any help is appreciated

Hello,
I have the following situation. I have a single publication on my publisher Server. This publication is created using SQL Server Manager. Snapshot is created completly. Now I want several Pull subscriptions from several machines to work with this publication (One subscription per machine). I'm creating these subscription using RMO. I'm synchronizing data using RMO again. My code workflow is:
Syncronize -> success -> do nothing
-> fail -> Check if everything with Publisher and Publication is ok -> Generate Snapshot -> Create Subsscription -> Sync again. (I tried to eliminate Generate Snapshot step but couldn't because I receive error that I must rerun Snapshot Generation.)
When I tested my code per single machine it's working. Next test I tried was to run my program on 2 machines simultaneously.
The result is:
---> System.Data.SqlClient.SqlException: Another snapshot agent for the subscription(s) is running or the server is working on a previous request by the same agent.
or:
---> System.Data.SqlClient.SqlException: Unable to acquire the replication merge administrative application lock for database 'XXX'. This could be due an active snapshot running while the schema change (DDL) or the administrative proc change was attempted.
Replication merge admin stored procedure 'sp_changemergepublication' failed for publication 'YYY'. This could be due an active snapshot running while the admin proc was called.
The problem is obvious but because I'm new to the replication I'm not sure if I did general mistake in what I want to achieve. Any advices how can I fix my problem will be highly appreciated.

So, Microsoft decided that they were deprecating Transactional Replication with Updatable subscriptions. In that case, you have 2 options (if I am correct): Pay for Enterprise (if you are already not) and use peer-to-peer or use bidirectional transactional replication which is basically setting up a transactional from db1 to db2 and also transactional from db2 to db1.
The issue I see in both cases is conflict resolution. With updatable subscriptions, you could specify how to handle the conflict. With either of these 2 options (from what I can tell) you cannot allow the engine to handle this for you.
Any thoughts? Seems like a slap in the face to those who have been using MS for years and a damn good reason for companies that rely on updatable subscriptions to not upgrade to 2012.

I am executing sp_dropmergesubscription, but the rows are still in dbo.msmerge_subscriptions, and are still shown in the replication monitor as expired; the last synch dates were in april (expiration is set to 10 days). The 'expired subscription clean up' job appears to be running okay. I need to remove these subscriptions from the publisher as the subscribers are mobile devices, which sometimes are lost.

Hi all,
I'm admitedly a bit new to the world of replication, so please bear with me. I've got two SQL Server 2000 servers running in different locations. Server A does transactional replication over a push subscription to server B. If I need to make a minor change to one of the replicated tables (for example, dropping a no longer used column or changing a varchar field's length) do I need to drop the subscription, make the changes and then re-initialize the schemas and data?
For minor changes, I really hate having to knock out the site runnign off server B while the subscription is re-initialized and data is bulk copied back over. If I want to just make the changes manually on both servers will that cause problems down the line?
Any help is greatly appreciated.

Replication Type: Transactional With Updateable Subscriptions
SQL Server Version: SQL Server 2005 Enterprise Edition
Publisher, Subscriber1 and Subscriber2 all on same SQL Server
Problem: I am trying to set up a transactional replication with two updateable subscriptions. All three databases are a carbon copy of each other. Every table to be replicated contains an identity key column. I've been asked to create the replication without assigning separate identity ranges for the publisher and the updateable subscriptions. In other words they want a continous ID range. Can this be done without managing identity ranges programatically outside of SQL Server itself?
Example:
Publisher inserts into table test1 in database1. This creates ID 100 for the record. ID 100 replicates to Subscriber1 (database2) and Subscriber2 (database3).
Subscriber1 and 2 identity seeds are then incremented to ID 100. So far, all three databases have the same identity seed in table test1. Subscriber1 inserts into table test1 in database2. This creates ID 101 for the record. ID 101 is replicated to Subscriber2 (database3) and to the publisher (database1).
Subscriber2 identity seed is then incremented to ID 101. However, the Publisher retains it's original identity seed of 100.
Insert into Publisher table test1 will fail since it will try to insert the identity seed of 101 which is taken.
I have tried identity range management Automatic and Manual. Both seem to have some limitations in managing identity seeds unless different identity ranges are assigned for publisher and subscriber.
Can someone recommend a solution to this problem? Can this be done natively in SQL Server 2005 replication. Or can some recommend another approach to make this work?

I set up a sql server 2005 database as publisher for about 50 sql mobile subscriptions. Yet in the replication monitor windows, it shows in subscription columns is 26549. Does it mean I have 26549 subsriptions or it means 26549 synchronizations?
thanks,

Greetings:
I am working on a replication setup using transactional replication using with pull subscriptions and a separate distributor. The pull subscriptions are located on a SQL cluster using the virtual SQL Server name as the subscriber; when the box fails over, we get an error of missing replication.dlls. Researching further, we found that replication only works on one node of the subscriber.
Any ideas on what we did wrong in the setup?
Thanks,

Hello,
If I want to access or modify my local subscription data(not the configuration) how can I do that(from sql server 2005 or from asp.net)? Also can i update directly to the local subscriptions data or do I need another layer which will update from a table for example??
Thank you

Greetings,
We periodically get the following message in our three server peer-to-peer transactional replication environment:
"One or more subscriptions have been marked inactive. Drop and re-create all subscriptions for this node that are failing with this error."
What causes a subscription to be marked inactive? What properties or settings can be adjusted to minimize or eliminate this occurrence?
Everthing seems to be running OK and then we get the message. It afflicts the higest change volume publication on our slowest overseas server.
Thanks,
BCB

I doubt this is possible, but can someone think of a way to change the email address used for sending report subscriptions based on the report or subscription?
It's a need that I've heard from a number of different clients. Scenario: a company has one reporting services server with reports running from numerous departments. Report subscriptions are sent to internal and external email addresses and there's a business need to use different "from" addresses based on the report (or audience).

We are running Reporting Services on an Application server, side by side with a web application. The server exists outside our corporate domain due to the fact that our external vendors need access to the application (not the reports). Our web app uses a third party mail system to funnel the application email thru our corporate exchange server. Since Reporting Services is not connected to our domain, it can not authenticate to send reports via e-mail subscriptions. I am looking for alternatives to make this work from outside the domain.

We've got a lot of user subscriptions that need to be re-run (data was bad on the initial run). Is there anyway to do this programatically or behind the scenes? We're looking for a way to avoid going into each subscrption and re-running.
Thanks.

I am getting continuous errors in publisher/distributor server
Background: Transactional replication (Push) with one publication (above 30 articles (tables)) and 1 subscriber. Publisher/Distributor is 2008r2 SP2 & Subscriber is 2008r2 sp1
Current Problem:
Repl-Distribution
Message
Replication-Replication Distribution Subsystem: agent PubServername-Production-ProductionReplication-Subscriberservername scheduled for retry (One of the replication job). Query timeout expired.
When I open the replication monitor..In the first tab it is showing performance excellent but when I double click on the publiscation, it is showing errors under distributor to subscriber tab and there are some undistributed commands 5873507, estimated time to apply these commands, based on last performance is 1:06:05:05
Question 1: Do I need to reinitialize the subscriptions? How to find out the problem what went wrong with replication
Question 2: If I want to do any schema changes @publisher do I need to stop the log reader agent and start after the deployment? In my case both publisher/distributor are on the same server (Transactional Replication)

I just installed SQLExpress, with reporting services on my own laptop
However, when I go to http://localhost/Reports/, I can see my reports uploaded, but the subscription links are not available. In Properties, I cannot see "Execution" either.
Can someone help me to get the Subscriptions feature enable again?
Thanks,

Attempting to run any kind of subscription, we are receiving no error message, but not reports either
I think this maybe relatd to a system account used in setup being removed? does this sounds reasonable even though old subscriptions are stil working?
i have looked in the rsreportconfig file but the account is encrypted, how can i change this?

Hi,
I have generated a report and uploaded that report to reporting services. It works fine. I have created a subscription for the same report and scheduled the job to run the report. The report is not running.
I have tried the same report in different server and it works there.
I have sql server 2000 and sql server 2005 installed in the same server. I am using sql server 2000 reporting services but 2005 database. Will that creates a problem?
Can anyone please help me in this.
Thanks,

Per BOL, I can assign the following task to a role, and if I give role to SSRS user, they can see ALL SUBSCRIPTIONS. If so, WHERE do they see the ALL SUBSCRIPTIONS? Will they show when selecting MY SUBSCRIPTIONS, or some other way?
{{Manage all subscriptions: View, modify, and delete any subscription regardless of who owns the subscription. }}
I am full rights admin on the box, and yet to find way to see ALL SUBSCRIPTIONS as well.

At the moment, the only way (that I know of) to test a subscription seems to be to schedule it a few minutes ahead in time and wait for it to happen. Dies nayone know if there are plans for and "Execute" or "tTst" button? It would be nice to have one.

Help! After searching through the forums and the web in general, I cannot find a reference to this problem. On a new SBS 2003 R2 server, with a clean install of SQL Server and reporting services, I have reporting working fine except that the reports have no Subscriptions tab visible. Also when I go to "Site Settings" and "Manage Shared Schedules", I get an error:
"The feature: "Scheduled report execution" is not supported in this edition of Reporting Services. (rsOperationNotSupported)
Interrogating the SQL Server, I find that the edition is reporting as Workgroup, which should have scheduled report execution.
Please help as this is a big problem for this server deployment.
Thanks

Hi There
I need to get rid of all subscriptions (including cleaning up all associated sql jobs) for RS 2000 and 2005.
We have hundreds of reports , going through them 1 by 1 is not an option.
When i look at the system tables, i join Subscription to Catalog, but i find reports with subscriptions in the system tables but when i go to Report Manger there is no subscription for the report.
In a nutshell , how can i see all valid subscription for all reports in RS, how can i delete all of them and make sur eall sql jobs associated etc are deleted.???
Thanx

Where in the backend database can I find who a subscription was sent to? I know in the report server database the subscripitons table has a description and last status field, but these fields are cutting names off when the list is large. Is there any other place where this information is stored?

We're new to SQL Reporting Services and have a new SQL 2005 server.
I'm having a problem activating scubscriptions.
- "New Subscription" is greyed out in Server Management Studio.
- Subscribing via the browser, even as the Content Manager, allows you to fill in the form for the subscription but then reports the following error;
"The current action cannot be completed because the user data source credentials that are required to execute this report are not stored in the report server database. (rsInvalidDataSourceCredentialSetting)"
Any suggestions?
Found the problem.
When configuring the Data Source the "Impersonate the authenticated user after a connection has been made to the data source" button should be off.

Why don't I have the options to choose SQL Server 2005 and SQL Mobile 2005?

Hello,
I have a dril lthrough report which takes a long time (5-7 minutes) to fetch the results. The reason is that the data it returns is huge as it fetches sales data till the lowest level.
when the users later on trz to export it to excel it takes again a lot of time and eventuallz the szstem freezes. I think the volume of export might be in the range of 14/15 MB.
Is there a way to reduce first the execution speed of the report and then secondly reduce the time to export the report?
Or a way where the report is executed once a day and everyone shares the already published report?
regards
Josh
