Hello!

While I can't get too far into the functional issues and requirements for a visibility-only solution, I can tell you that some of G-Log's (and now Oracle's) largest clients are using GC3 / OTM for visibility. Clients like Exel/DHL, FedEx, etc and that some other large parcel companies are looking at OTM as a solution. In fact the visibility model in OTM was built out specifically for Exel Logistics.

From a technical perspective, the large visibility clients had to ensure that their OTM infrastructure was sized and tuned appropriately in order for it to manage the large volume of integration transmissions (tens of thousands a day). In addition, they've had to adopt data retention policies in order to keep their DB sizes in check, since OTM stores the XML messages for each transmission by default.

Hope this helps!

Thanks!
