replication

This is the scenario: I have a MySQL server with a database, let's call it consolidateddb . This database a consolidation of several tables from various databases I have another MySQL server, with the original databases, these databases are production databases and are updates daily. The company wants to copy each update/insert/delete on each table in the production databases to the corresponding tables in consolidateddb . Would replication accomplish that? I know that replication is done on a databas to database, but not on tables that belong to different databases to one target database. I

rI've looked at the questions and indeed the RavenDb docs. There's a little at RavenDb Index Replication Docs but there doesn't seem any guidance on how/when/where to create the IndexReplicationDestination Our use case is very simple (it's a spike). We currently create new objects (Cows) and store them in Raven. We have a couple of queries created dynamically using LINQ (e.g. from c in session.Query<Cows> select c ). Now I can't see where I should define the index to replicate. Any ideas? I've got hold of the bundle and added it to the server directory (I'm assuming it should be in RavenDB.1.0

What is the difference between Replication and Mirroring in SQL server 2005? In short, mirroring allows you to have a second server be a "hot" stand-by copy of the main server, ready to take over any moment the main server fails. So mirroring offers fail-over and reliability. Replication, on the other hand, allows two or more servers to stay "in sync" - that means the secondary servers can answer queries and (depending on setup) actually change data (it will be merged in the sync). You can also use it for local caching, load balancing, etc. Remus Rusanu Mirroring is a feature that creates a

I have 2 MySql with a master/slave configuration and the replication is failing. The MySql Master crashed and a new register in the mysql-bin.index was created. I deleted this new register because this file was not existed in the file system. Then the MySql Master restarted successfully. Now, I have the next error in the slave: mysql> show slave status \G *************************** 1. row *************************** Slave_IO_State: Master_Host: 10.64.253.99 Master_User: replication Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.001050 Read_Master_Log_Pos: 54868051 Relay_Log

I am trying to setup filtered replication between a master and user database. Documents in the master contain a list of user groups that have permission to the document. { _id: 'one', groups: ['a', 'b'] } { _id: 'two', groups: ['c', 'd'] } I created a filtered view of the database that only allows user with the group to get a copy of the replicated document (hard coding the group of 'a' in this example) { filters = { users = function(doc, req){ return doc.groups.indexOf(req.query.group) != -1; } } } I then create a replication document in the _replicator database { source: "master", target:

I build a replication set with one primary, one secondary and one arbiter on MongoDB 3.0.2. The primary and arbiter are on the same host and the secondary is on another host. With the growing of write overload, the secondary can't follow the primary and step into the state of recovering. The primary can connect to the secondary as I can log to the secondary server by Mongo shell on the host of primary. I stop all the operations and watch the secondary's state with the command rs.status() and type the command rs.syncFrom("primary's ip:port") on secondary. Then the result of the rs.status()

I will be building an in-house, Occasionally Connected App (OCA). What technologies would you suggest I employ. Here are my parameters: .NET Shop( 3.5sp1 ) C# for code behind ( winform,wpf,silverlight ) SQL Server Backend ( 2005 or possibly 2008 pending approval ) Solo Developer Solo SQL Administrator Low Tech end users Low bandwidth to 5 Branch offices This is a LOB app but not a POS. Majority of users have laptops that they take to Member's Home The Data for this App is stored in 5 separate Databases, though in one SQL instance. I am looking for specific recommendations on which path to
