Backing up the Oracle GoldenGate Environment
After you start Oracle GoldenGate processing, an effective backup routine is critical to preserving the state of processing in the event of a failure. Unless the Oracle GoldenGate working files can be restored, the entire replication environment must be re-instantiated, complete with new initial loads.
As a best practice, include the entire Oracle GoldenGate home installation
($OGG_HOME
) in your backup routines. There are too many
critical sub-directories, as well as files and programs at the root of the
directory, to keep track of separately. In any event, the most critical files are
those that consume the vast majority of backup space, and therefore it makes sense
just to back up the entire installation directory for fast, simple recovery. Apart
from Oracle GoldenGate home installation directory, you must back up the
$OGG_ETC_HOME
directory, which contains the configuration
settings for the Oracle GoldenGate installation.
