How To Disable AD Replication
Arnau Cyr
At each Subscriber on the subscription database, execute sp_removedbreplication to remove replication objects from the database. This stored procedure will not remove replication jobs at the Distributor.
If all replication publishing and distribution objects are not dropped before you execute sp_dropdistpublisher and sp_dropdistributor, these procedures will return an error. To drop all replication-related objects when a Publisher or Distributor is dropped, the @no_checks parameter must be set to 1. If a Publisher or Distributor is offline or unreachable, the @ignore_distributor parameter can be set to 1 so that they can be dropped; however, any publishing and distributing objects left behind must be removed manually.
Call the UninstallDistributor method. Pass a value of true for force to remove all replication objects at the Distributor without first verifying that all local publication databases have been disabled, and distribution databases have been uninstalled.
This article describes how to remove a replication from a computer that is running Microsoft SQL Server. To remove a replication, you must drop the subscriptions, the publications, and the distributor that is configured for the replication. You can remove the replication by running the Transact-SQL script that is generated by SQL Server Enterprise Manager or SQL Server Management Studio. However, if you cannot generate the Transact-SQL script to remove the replication, you can manually remove the replication by using system stored procedures and other Transact-SQL statements. This article contains information about system stored procedures that can be used in this process.
After you remove all the subscriptions that subscribe to a publication, you can remove the publication. After you remove the publications at the publication database, you must set the replication database option for the publication database to false. To remove a publication, you can use the following system stored procedures:
sp_removedbreplication: You can use the sp_removedbreplication system stored procedure to remove all the replication objects from a database without updating the data at the distributor. You must run the stored procedure at Publisher on the publication database or at the Subscriber on the subscription database. The following is the syntax for this stored procedure:
I have a SQL Server (distributor and publisher) 2008 which is replicating using both snapshot and transactional replication to replicate to a couple of subscribers. There is plenty of information here -us/sql/relational-databases/replication/disable-publishing-and-distribution on how to permanently disable replication.
I have learned my lesson that when things go amuck it's a complete disable, remove, and re-setup to get everything working again, and there are too many publications to make this an option just to temporarily disable this.
For snapshot replication, you shouldn't need to do much since the only time there's activity is when a snapshot is being created and delivered to the subscriber. You can just disable those jobs for the duration of your event and re-enable them when you're done.
I'd recommend leaving the rest of the replication settings in place in case you decide to revert to your previous configuration. That way you'd just have to push the data over and reset the slave position (don't forget to remove skip-slave-start) rather than recreating the setup whole-cloth.
Editing the my.cnf file alone is not sufficient to disable replication. In fact, it is no longer the recommended way of enabling it. Putting entries in the my.cnf file are only effective for the next startup and behave as if you had entered the command into the mysql client:
You use the Amazon S3 console to add replication rules to the source bucket. Replication rules define the source bucket objects to replicate and the destination bucket or buckets where the replicated objects are stored. For more information about replication, see Replicating objects.
You can manage replication rules on the Replication page. You can add, view, enable, disable, delete, and change the priority of the replication rules. For information about adding replication rules to a bucket, see Using the S3 console.
To enable or disable a replication rule, select the rule, choose Actions, and in the drop-down list, choose Enable rule or Disable rule. You can also disable, enable, or delete all the rules in the bucket from the Actions drop-down list.
I had Index Clustering and Replication (Rep Factor 3) enabled on my Splunk 5.0.4 indexer cluster, but had to disable replication because my cold storage (NFS) was too slow -- replication was causing the cluster to panic as the storage became farther and farther behind.
Example: The Powers That Be say to disable an account, but nobody is really sure where the user is located that day. As a crude workaround, I wrote my Disable-Employee cmdlet to disable the user on the PDCe first, then check every single RODC for that user's credentials, and if found, disable them there as well.
How do I stop the replication and delete the files from one of the servers, while keeping the data intact on the other server, without causing a mess and potentially making the shares unavailable or experiencing data loss? DFS can stay, just the replication needs to stop. I'm aware how to stop DFS:
I have not found any documentation suggesting dropped column actions are always replicated. In fact, I can only find information stating with replicate_ddl disabled, statements which add or drop columns are not replicated.
In short, I am dropping the subscription, removing the article from the publication, dropping the column, performing any DML statements, adding the article back to the publication, and recreating the subscription with no sync (@sync_type = N'replication support only').
Indicates if schema replication is supported for the publication. replicate_ddl is int, with a default of 1 for SQL Server Publishers and 0 for non-SQL Server Publishers. 1 indicates that data definition language (DDL) statements executed at the publisher are replicated, and 0 indicates that DDL statements are not replicated. Schema replication is not supported for Oracle Publishers. For more information, see Make Schema Changes on Publication Databases.
When a column is dropped, sysarticlecolumns must be updated to prevent new DML statements from including the dropped column which would cause the distribution agent to fail. The @replicate_ddl parameter is ignored because replication must always replicate the schema change. When a column is altered, the source data type or nullability might have changed, causing DML statements to contain a value that may not be compatible with the table at the subscriber. Such DML statements might cause distribution agent to fail. The @replicate_ddl parameter is ignored because replication must always replicate the schema change.
I'm trying to test Distributed File Service before implementing it. I want to see first hand how the replication will work when coming back from an outage and finding new versions of the same file in multiple places on a mesh topology. To do this, I want to disable replication between the folders and then load up different versions of files on each before re-enabling.
So from DFS Management, I accessed my replication group and from the connections tab disabled each member server. This should disable replication entirely, right? Files are still replicating instantaneously with no problem....
Disabling the network adapter would achieve the goal. Disabling the connection infers that you break the DFS replication partners (deleting them) which is not what you want to do. Disabling the network interface will work for your test.
Very true Brian, replication does have its limitations and relies heavily on your AD. However I strongly suggest you look at upgrading your file servers to Server 2012 R2. DFS and DFS Replication has changed quite a bit over the years. You will find that after the upgrade many of these issues you face now have been resolved:
Absolutely. Its critical that you keep your AD healthy, but not just for your DFS replication, for the overall health of your network! I like to recommend running a DCdiag at least once a month and monitor your AD health.
You can set up replication automatically using the graphical setup utility when youfirst install Oracle Unified Directory, if you configure all of the directoryservers in the same manner. You cannot use the setup command to configure replicationin command-line mode. If you set up your directory servers by using thesetup command, you must use the dsreplication command to configure replication betweenthe servers.
In any topology, you should have two replication servers for availability, in caseone replication server fails. Replication servers are responsible for keeping track of allchanges in the environment. Each replication server contains a list of all otherreplication servers in the topology.
Note - You cannot run more than one instance of the dsreplication enable commandto set up replication between multiple servers in parallel. Rather, run the dsreplication enable command successively for each pair of replicated servers in the topology.
The following command enables replication of the data under "dc=example,dc=com" between twodirectory servers, host1 and host2. Both servers use the default administration port(4444). The command creates a replication server instance on host1, port 8989, and asecond replication server instance on host2, port 8989.
Using dsreplication enable between two servers automatically configures a replication server on each host.You might want to configure replication between two directory servers without creating areplication server on each host. Use the --noReplicationServer1 or --noReplicationServer2 options toadd a directory server to a topology without creating an additional replication server.Remember that a replicated topology must contain at least two replication servers toavoid a single point of failure.
