Creating Replication Process
Data replication process types are summarized in the following table.
| Replication Type | Description |
|---|---|
| Data Transfer | This process transfers the data to the target system but does not trigger a table switch or a switch of data replication directories. |
| Data Publishing | This process publishes data that have already been transferred to the target system. The process triggers all necessary table and directory switches as well as concomitant database commits to persist the changes. Note:
Data publishing can only be executed on the results of a process of type Data Transfer executed immediately before. Data transfer and publishing cannot be separated for certain replication groups. |
| Data Transfer & Publishing | This process accomplishes a complete replication process, including data transfer and publication. The following replication groups must be replicated using a process of the type Data Transfer & Publishing:
|
| Undo | An Undo process rolls back a data replication process of type Data Publishing or Data Transfer & Publishing, which has been completed successfully. Undo restores the target system state prior to executing the data replication task that is rolled back. Undo can only roll back the most recent data replication process. Note that Undo cannot be used with replication groups that involve user data, namely:
