koder++хотелось как админу MSSQL2К узнать поддерживает ли Informix 7 DS репликацию? сложно ли её настроить?
Репликации они разные бывают...

Data replication refers to the process of representing database objects at more than one distinct site. Dynamic Server supports two methods of data replication: High-Availability Data Replication (HDR) and IBM Informix Enterprise Replication (ER). You can combine HDR and Enterprise Replication on the same database server. For more information, see the IBM Informix: Dynamic Server Enterprise Replication Guide .

High-Availability Data Replication
HDR supports synchronous replication of an entire database to another database server, providing a hot standby in case of a catastrophic computer failure. For more information, see High-Availability Data-Replication Parameters. High-Availability Data Replication (Enterprise/Workgroup Editions), and Using High-Availability Data Replication (Enterprise/Workgroup Editions).

Enterprise Replication
Enterprise Replication supports asynchronous data replication over geographically distributed database servers and allows you to replicate both entire databases and subsets of databases and tables. Enterprise Replication offers limited support of user-defined data types. For detailed information on Enterprise Replication, see the IBM Informix: Dynamic Server Enterprise Replication Guide .
