Before OpenEdge Replication starts, the source and target databases are automatically checked to ensure that the databases are identical in the following ways:

  • The logical structure—but not necessarily the physical structure—of the databases. (All user-defined areas must be identical except the AI areas.)
  • The versions of the databases.
  • The supported platform.
  • The database block sizes.
  • If large file support is enabled, it must be enabled on both databases.
  • Before-Image (BI) block sizes.

For added protection against data loss, locate the target database on a different machine from the source.
