GOAL:
Do offline updates to a Fathom Replication Source database get replicated to the Target database?
GOAL:
Do offline schema changes to a replication enabled source database get propagated to the target database?
GOAL:
If the source database is truncated, is the target database truncated?
FACT(s) (Environment):
All Supported Operating Systems
Fathom Replication
OpenEdge Replication 10.x
FIX:
Yes. Any changes made to the source database while replication is enabled will be replicated to the target database the next time the source and target are synchronized. These changes are recorded in the ai notes.
It is worth noting that as each ai extent is filled, it will be set to status "LOCKED" until such time as the replication processing is fully re-established. Once the synchronization point is reached, the notes are processed on the target database. Only then will these ai extents be set to status "FULL", at which time they can be rfutil -C EMPTY to be made available for re-use. It is therefore advisable to first check that there are enough ai extents available to record these changes before undertaking them.
In the case of truncating the bi file on the source database, the target database isn't truncated as such. Meaning, that whatever undo/redo actions are taken against the source are recorded in the ai notes. The target bi file will not reduce in size. It is therefore similarly advisable to have more fixed bi extents on the target database than the source database.
