NT Service

Do you provide Application Servers as NT Services?

NTService_1
Fail-over and load-balancing

What kind of fail-over and load-balancing support does dbOvernet provide?

LoadBalance_1
Performance: Multi-tier vs. Classic C/S

What performance-improvements can be reached by using the dbOvernet-components (three-tier-model) instead of writing a classic Client/Server-application with use of sql-select (not filters), triggers and stored-procedures (Oracle-Database)? If there are improvements: why? and how much? (the customer's WAN has a quite limited throughput).?

BDE Alternative - DBISAM Replacement

Do you have a BDE-alternative that uses DBISAM (like Halcyon/ElevateSoft products)?

DBISAM_1
BDE Replacement/Compatibility/Transition

1 Can dbOvernet function as a BDE replacement for normal Client/Server work, or is it only a MIDAS replacement?
2 If it can be used as a BDE replacement, what is the situation with TDataset-based components? What are the compatability issues involved?
3 If dbOvernet is not the BDE alternative we are looking for, has dbOvernet been tested with any of these alternatives? How did it perform?
4 When we finally do step up to multi-tier (about 6 months from now), how smooth a transision can we expect in taking dbOvernet from C/S to multi-tier?

BDE_Replace_1
TDataset dependant

I am using a custom TDataSet descendant. Is it possible to use dbOvernet with this Custom DataSet directly (No need BDE)?

BDE_Replace_2
Authentication/BDE requirement/pricing

1. I read in the help file that the TdbOAppServer component has an event called OnClientConnected. From within this event handler, is it possible for the server to obtain information about the client's user name, password, and IP address? We need that information to filter out unwanted connections.

2. If I were to install a program that uses one of the dbOvernet components on a machine, does the Borland Database Engine (BDE) need to be installed on the same machine as well?

3. What is the cost of a license to use the dbOvernet component suite?

Server_1
Pricing and distribution

If we sell an application that uses your middleware components (dbOverNet), does our client have to pay any charge to you ? I mean, does our client has to buy a server licence ? I am not sure if I fully understand your licence policy.

License_1
Upgrade policy

Hello - I am interested in getting your product. I notice that you will have a version 2.0 release soon [ed note: already released]. If I go ahead and get your latest release now will I get ver 2.0 update for free or will there be another charge incurred to get the newer version. I am interested in getting the Developer kit, component source code and one server license.

Upgrades_1
MaxRecords and GetNextPacket

How can you limit the Packet size? I mean the number of records retreive at a given moment. This would help client-side performance. By the way, thanks for your concern, your Technical support is excellent.
