Mediator/Oracle

sorry for posting this again - but I would really appreciated if someone
would knew some more details about this issue (might be Jacek?).

It's about Medaitor and MarkerTables.

Mightbe someone can explain it for me what the purpose of The "Marker
table" in Mediator is?
Any samples for a application?
Is to share e.g. record lcokes between Clipper and DELPHI apps under
Mediator?

I read the docu but the purpose is not absolutely clear to me :-(

Any info much appreciated.

TIA

Regards
Fred
