SQL 2012 :: Transactional Replication - How To Remove Orphaned Articles
Jan 27, 2015
We are runnning on SQL Server 2012 SP1 + CU9.
I have found some articles with no publication in our transactional replication.
For example, running this:
select p.publication,
a.publication_id,
a.article
from dbo.MSArticles as a
left outer join dbo.MSpublications as p
on a.publication_id = p.publication_id
shows this:
NULL1org_Community
NULL3org_Community
Purchasing to EDW5org_Community
NULL1org_Division
NULL3org_Division
Purchasing to EDW5org_Division
How can I get rid of the articles that are not part of a publication?
I can't use sp_droparticle because it requires a publication which these articles do not have.

I have an existing publication in sql 2012 with 2 articles, and then I add 2 more articles. After that when I generate a snapshot, will the snapshot be generated for 2 new articles only or for all 4 articles?
I remember adding 1 new articles to one existing publication with 150 articles and when I generated snapshot, it was generated only for 1 article. But I don't remember clearly.
Does it behave differently for small and large number of articles?

Hello,
My company is moving to a SQL Server-based packaged application early next year. We€™re planning our SQL Server architecture but have some questions that I can€™t readily find answers for. I€™m hoping someone here can point me in the right direction.
We have three servers, I€™ll call them A, B, and C. We want to duplicate all changes to certain databases on server A to server B, then duplicate changes to selected databases and tables on server B to server C.
Ideally we€™d run SQL Server 2005 Enterprise Edition on all three servers, but the packaged application vendor does not support SQL Server 2005 yet, only SQL Server 2000. Our license agreement with them does not allow us to use replication on server A. We€™re free to do whatever we want on our other SQL Servers, but server A must sit alone, untouched, like a monolith on a far-away moon. (I€™m lobbying to have the server named Tycho, or TMA2.) Stranger still, they€™re OK with log shipping from server A to other servers. We€™ve tried to explain that replication and log shipping are both core function built into SQL Server, and that if one is acceptable, then both should be. Their fear is that replication could cause performance and stability problems, and to eliminate this possibility they€™re ruling out replication on server A.
Given these constraints we€™re resigned to using SQL Server 2000 Enterprise Edition on servers A and B, and SQL Server 2005 Enterprise Edition on server C. We plan on periodically shipping logs from server A to server B and applying them at server B.
We€™d like to know if it is possible to also use transactional replication on server B to duplicate changes from server B to server C. I€™ve used log shipping and replication in the past, but never at the same time. My understanding is that a database goes into recovery mode while a transaction log is being applied and that any user changes to the database after the log has been applied will cause later log applications to fail. The scripts I€™ve seen that are used to apply the transaction logs put the database into single user mode after the log has been applied to prevent this.
This raises a few questions:
If we try to RESTORE a log to a database being used as a source for transactional replication articles, will the RESTORE fail? Or will the RESTORE start and break the transactional replication? I€™ll test this on my own, but it€™d be nice to know if anyone has already experienced this.
Is it possible for us to have a database in read-only mode serve as the source for transactional replication articles? (I can€™t imagine why not, ever though it seems counter-intuitive - why would you want to replicate transactions from a database that has no transactions?)
If the answer to number two is yes, can we suspend transactional replication on a database, RESTORE a log to the database, put the database into read-only mode after the RESTORE, and restart the replication on the database?
Thanks in advance for sharing your wisdom, everyone!

I am setting up filtered replication(tran repl) for a table that is 2+ TB in size. The filtered rows are less than 1% of total size.When I run the snapshot, sometimes it complete in 27 mins(I have already optimized the snapshot agent profile) and sometimes it runs for ever. Mostly it runs forever, so the chances of it finishing soon are really very less.I have infact created filtered index just to cater to the query in the filter i.e. on the filter predicates. The reason its flipping flopping is due to the incorrect plan that it chooses. I can force the right index and the filtered query runs just fine but. I cannot use the query hints when I am adding the filter in replication as its not allowed.
I then went ahead and created the plan guides to force the best plan. But the plan guide was not used because even if there is a single space in the actual query that replication runs in the background the plan guide will not be used(testing on plan guides has proved this). The query needs to be ditto same including whitespaces and carriage returns. I then ran profiler and found that there is a view that replication creates and executes to extract the filtered rows and BCP it. Got the text of the view and created the plan guide on it but it was still not used because sp_helptext output seems to be different than what is actually being fired by replication internally.
Further, I collected the verbose log with level 2 and tried to find out if the main query shows up there with no success.
(a) I can't use the plan guide because I do not know the exact syntax(I mean I have the query but I do not know the white spaces, carriage returns, etc) and
(b) I cannot use query hint while filtering the article.
1. I cannot afford to have downtime.
2. I cannot use backup and restore option either.

We are planning to setup HA using either AAG or FC. ON my production environment (P), I have transnational replication configured for 2 of databases out of three. These data get replicated to another server( C1) hosted on cloud, with local distributor at P.
If I configure AAG/ FCI , how do I handle failover?I wanted to setup P as primary AAG with two replicas as S1 and S2. P->S1 will be synchronous while P->S2 will be asynchronous.Incase my P goes down how the replication will failover S1? Incase P and S1 goes down how do I failover to S2 with the replication.

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 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?

I am using SQL 2012 SE and implementing transactional replication. I need to insert the rows from publisher database tables to new tables, drop the old tables and rename the new tables with the old table names.
For example:
Publisher database tables that are being replicated:
Table1
Table2
Table3
and I am going to create new tables in publisher database
Table1_new
Table2_new
Table3_new
Move data from
Table1--->Table1_new
Table2--->Table2_new
Table3--->Table3_new
Drop constraints from and then tables (does this require articles to be removed from replication?)
Table1
Table2
Table3
Rename
Table1_new to Table1
Table2_new to Table2
Table3_new to Table3
Does this require replication to set up from scratch or add the three articles only to replication? Is there a way this can be done without pausing or reinitializing replication or without removing articles and adding them back?

We have a database which is (a subset of tables are) replicated to another via transactional replication. Whilst most changes made at the published database reach the subscriber within a matter of seconds, we have a SQL Agent job which performs a calculation in the published database and then immediately exports data from the subscriber using log shipping. The result is that the calculated changes do not make it through to the exported transaction logs in time.
Is there a way to manually "refresh" the subscriber databases using T-SQL?

I have a transactional replication environment that creates subscribers on another server as a staging area for an ETL process to a data warehouse application on a 3rd server which is the report repository. Currently the ETL process runs every 10 minutes and performs it's function across approx 150+ subscriber databases and consolidates it to the data warehouse.
I have an SLA of 2 minutes. I'd like to rework the ETL process (which run as SSIS job at the moment) to be specific to a single database and fire that one ETL proces when changes have been applied to that subscriber database only. Of these 150+ databases generally only about 8-10 are updating the subscriber at any given time per Repl Monitor. I'm thinking that if I only have a few transactions to apply to a single db the ETL would run in seconds dynamically as the subscriber is update.
The issue is how to fire the ETL process upon completion of updates to the subscriber DB? I'm thinking of using SP_Start_job passing the DBID to update the warehouse but unsure whether this is possible but if so where to trigger it.

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'm new to replication and set up a Snapshot Replication on the tables in my sample database. Â Everything seemed to work (database created on Subscriber instance, jobs set up, etc) but the articles (tables) are not being created in the subscriber's database. Â
I can see the files created in the folder but I don't see the tables or the data. Â Also, I confirmed that the articles are checked so they should be included.

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

Been asked to restore an orphaned MDF file leftover after a botched uninstall - no .bak file. Tried to reattach, but got an error, I don't think it had been detached. My initial answer was, "No, very likely can't be done".
Am I right? Or is there a way of attaching it that doesn't require it to have been detached?

All is happened when a server crashed some weeks ago and it was removed from my network. After that, under my SQL Server 2012 I get an orphaned account which cannot be removed. This account is a computer account related to an old SCOM installation.
If I try to execute the command DROP USER [NETWORKSERVERNAME$] I get the following error message:
The database principal has granted or denied permissions to objects in the database and cannot be dropped. Msg 15284, Level 16, State 1, Line 1
The database principal has granted or denied permissions to objects in the database and cannot be dropped.But if I run the following command to know all permission granted to the account, I get an empty result:
select * from sys.database_permissions where grantee_principal_id = user_id ('NetworkSERVERNAME$');
Furthermore, following the instructions provided by the official KB for troubleshooting orphaned users, I get another error [URL].
sp_change_users_login 'update_one', 'NetworkSERVERNAME$', 'NetworkSERVERNAME$'
Msg 15291, Level 16, State 1, Procedure sp_change_users_login, Line 114
Terminating this procedure. The User name 'NetworkSERVERNAME$' is absent or invalid.
The only thing I can retrieve is 15 permissions that this account granted to another account in the past:
select *
from sys.database_permissions
where grantor_principal_id = user_id ('NetworkSERVERNAME$'
--
class class_desc major_id minor_id grantee_principal_id grantor_principal_id type permission_name state state_desc
17 SERVICE 65538 0 5 19 SN SEND G GRANT
And more 14 rows…
resolve my issue and safe delete the account SERVERNAME$? I need this because I have to reinstall SCOM with the same computer name on another server, but installation fails due to this behavior.

Hey All - Another replication question:
Using VBScript in an ActiveX module of a DTS package...
Anyone have an idea how to add ALL articles to a Subscription.
The only way I can figure it is to load an array from sysobjects, then run sp_addarticle on each one.
Thanks for your help

We have many users with a mobile application running SQL Mobile and using merge replication to get data back to the SQL 2008 R2 database. This has worked very well for many years.
We now have a requirement to have this data reported on using Reporting Services. This is where it gets messy.
Due to a limitation of Report Builder(see this blog) we cannot provide access to users for creating their own reports. The report database is remote from the host and there is no VPN.
We hit upon the idea of creating an almost identical publication but the articles as read-only. It was only after this was done that we started having trouble with our existing mobile users.
It seems that a published article is EITHER Bi-directional OR Read-only even if they are in separate publications.
I then thought of using Transactional Publication but this too is blocked on creation with "automatic identity range support is useful only for publications that allow updating subscribers"(Merge and Transactional publication are mutually exclusive)
So in the final analysis is there a way for me to have merge replication AND some other form of SQL replication/data transfer that can have the same data transmitted readonly to a separate full SQL server database?

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.

We have a SQLServer 2005 Enterprise merge replication publication with SQL Mobile 3.0 subscribers (Windows Mobile 5.0 and 6.0). We do not use pre-computed partitions due to trigger performance issues with an SSIS/ETL application that supplies data to the merge database. We do use the "Optimize" (=true) option, though we have tried this both ways with no significant differences. We use filters and joins for each worker ID (as HOST_ID) from the subscriptions.
The sync times become increasingly worse after we run the snapshot and bring the publication online. I have tried rerunning the snapshots, this helps little, as it often behaves like the subscription was set to reinitialize and forces a big sync (reload of all data) to the subscriber. We have tried much of the obvious (e.g., flattening filters and joins, adding indexes, etc.).
When users are synchronizing, we watch replication monitor and notice that a lot of time is spent processing "enumerating inserts and updates for article [any article]", especially processing the many generations and batches. This is true for any follow-up syncs after the 1st big sync (initializing the subscription).
I read several posts regarding the batches and generations of changes, and decided to try increasing the €śDownloadGenerationsPerBatch€?. I tried adding this parameter to the snapshot agent job, and the job fails each time with a vague message, even with the default value of 100. How do you change this parameter for SQLServer 2005 Enterprise?
Any suggestions?
Thanks in advance,
Matt

I have been researching on the proper steps or sequence to follow to completely remove SQL Server 2012 Transactional Replication. Â 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. Â 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. Â SQL-P (publisher),Â
SQL-D (distributor) and SQL-S (subscriber). Â 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.

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...

On my distribution server there is a directory called mssql7
epldataunc that houses the bcp, sch and idx files for replications. A directory is created for each publication. Most directories are empty but some contain all the table idx, sch and bcp files for the publication. Some of these files are over 6 month. Does anyone know if these files are neccessary to keep and why do only some publications have these files. I am wondering if they are kept when you push the publicaiton and it errors out originally and you have to restart it? If any one can shed some like on this I would appreciate it.

Hi,
I am planning to do a transactional replication from production server to reporting server. In one of my database is having 150 tables in it, only 100 tables are having primary key . Remaining tables are not have primary keys. So i am not able to do transactional replication for those 50 tables. Could any one tell me how i have to approch transactional replication. Because i need to have production data at my reporting server in regular interval.
So pls suggest me .
I am using Sql 7.0 with service pack2.

I have a problem with transactional replication in SQL Server 7. I have two databases (a publisher-distributor server and a suscriber server) and when I do an UPDATE in the publisher database the Log Agent Reader reads the UPDATE as an DELETE-INSERT and when the suscriber pull the suscription and try to do first the DELETE the transactional replication stops because of the Foreign Keys in the suscriptor database (that are the same as the publisher).
If anybody knows how to solve it, please tell me

The process could not create file 'CONCEPCIONC$MSSQL7ReplDatauncCONCEPCION_Erik_Rep lication_Erik_Replication19991029153207Employer.sc h'.
Access is denied.
The SQLAgent is starting with same user account on both machines - admin rights and the same password. I have added this user to the (

Hello,
I am planning to implement replication between two servers (either snapshot/transactional). Those two servers are physically connected but we don't have domain concept i.e we connected both servers physically and it can be pinked from each other, but not under any domain (not also under different domain). How should I register SQL server& agent services to start with 'Service startup Account'. In this case I cannot start both servers using same domain Account, they how can I relate...

Hi guys can anyone help me with this issue. if so thankyou kindly.
1. created transactional publication (for tables, stored procs & views )
2. created empty database at subscriber
3. set up pull subscription at subscriber
4. ran the initial snapshot agent at the publisher
5. checked the schema files & found out it hadn't scripted the primary keys on the tables.
Problem: PRIMARY KEY AINT GOIN ACROSS, COULD ANYONE TELL ME IF IVE MISSED SOMETHING? THANK YOU MUCH APPRECIATED GUYS.
? Could it be that it is not picking up the primary keys on the tables because I am replicating stored procs and views with that publication?
? Should I break my publications into 3; say 1 for each object?
Thank you guys for taking the time to read this.

Hello all! I am setting up my first Replicated database, and want to get this right.
We are a Newspaper, and I will be Publishing the database that is the back end of the web server. The goal is to load balance the web site as well as to have a second identical server in case something goes wrong. Both the Subscriber and the Publisher need to be kept in sync as new articles are posted, so my client will just be updating the Publisher. But I'd like to keep a single set of usage statistics, so I was thinking of using Immediate Updating so the Subscriber can update the Publisher using two-phase commit.
What will happen if the Publisher shuts down and an update is attempted on the Subscriber? Will it just hang? Let's assume the worst - what if my Publisher is kaput? How do I determine that my other database is a Subscriber; and how do I stop it from being a Subscriber?
Thanks in Advance,

Hi
I have a requirement for pushing transactional publication to various subscribers. Each subscriber will need to receive a different subset of rows from a table. So I need all rows published, but with horizontal filtering at subscriber level. Is there a way of applying filtering at the subscription level.

I am using transactional replication between two SQL 2005 databases. On Sunday evenings, we run a maintenance plan that rebuilds the indexes on the publisher DB. When the plan runs, the replication receives errors and cannot continue. The error appears to be at the publisher level. The publisher runs continually and the subcriber runs every 10 minutes. The error states "cannot run sp_replcmds" Other than Sunday, everything runs fine.
Thank you
