Chapter 3: OpenEdge Installation Prerequisites
OpenEdge Replication
OpenEdge Replication provides database replication so that customers have access
to their database with minimal interruption.
OpenEdge Replication requires an OpenEdge Enterprise database or OpenEdge
Release Workgroup database license for each local or remote OpenEdge database
used in replication. You can replicate only from Enterprise to Enterprise database and
Workgroup to Workgroup database.
For more information about OpenEdge Replication, see OpenEdge Replication: User
Guide.
How you install OpenEdge Replication depends on whether you are:
• Installing OpenEdge Replication for the first time
• Upgrading an existing version of OpenEdge Replication
Note: When you install OpenEdge Replication, the AdminServer is started before
OpenEdge Replication is added to the AdminServer property files. This means
that OpenEdge Replication will not be enabled until the next time the
AdminServer is started. To enable OpenEdge Replication, simply stop the
AdminServer and restart it.
Installing OpenEdge Replication for the first time
There are two primary requirements to consider before you install OpenEdge
Replication for the first time:
• You should have a comprehensive backup plan in place for your database before
you begin the installation.
• You must decide where to install the OpenEdge Replication components.
Upgrading an existing version of OpenEdge Replication
If you are upgrading an existing version of OpenEdge Replication, be sure to back up
the following files:
• Source database
• Target database
• database.repl.recovery files
Because OpenEdge upgrades the database.repl.recovery files, once you upgrade
to OpenEdge 11.0 you cannot return to versions of OpenEdge Replication prior to
Release 11.0 using your OpenEdge 11.0 files. If you need to return to a previous
version of OpenEdge Replication on the source machine, you must back up your
source database, start after-imaging, and enable and configure OpenEdge Replication.
