Guidelines for working with source and target databases
Once you configure and start OpenEdge Replication, the replication process propagates any source database changes to the target database. For OpenEdge Replication to function properly, it is important that you follow these guidelines for working with source and target databases:
For added protection against data loss, locate the target database on a different machine from the source.
Both the source and the target machines must have the same endian ordering. Endian ordering defines how multiple byte integers are stored in memory—either by most-significant byte (MSB) or least-significant byte (LSB). Those systems storing by MSB are called Big Endian, and those storing by LSB are called Little Endian.
The term endianess is used in general to describe a situation in which binary files are portable between platforms; those platforms with the same endianess may use binary data transparently.
Typically, UNIX machines and Windows machines use different endian ordering for storage. Therefore, a Windows source database can be replicated to another Windows machine, but not to an HPUX machine, for example. An HPUX source database can be replicated to another HPUX machine.
For added protection against data loss, locate the target database on a different machine from the source.
