ADS or similar products

[norberto]

HI, i have use ads server and local for several years (10 ou more), this is no cheap, (have an free version to 2 users), but is very good and worth every penny paid. i have more than 40000 clients in an file, with another file with memo giant, and an current acount with more than 1 millions records. never have problem. this is my opinion. i plan change to my sql in future, because ads is now from sap, and the prices maybe change.

Norberto,
to give a practical example

headquarters: windows server + 20 clients

every branch of the company: vpn to headquarters + from 1 to 10 clients

Fivewin/xHarbour software

Are you able to calculate to costs of necessary licenses?
Thanks again
marco

Marco, no , i m not a resealer, try http://www.sybase.com ou in brazil, http://www.renet.com.br. another thing: i try connect 3 offices with vpn in past, without sucess, very slow, now i using windows terminal server (RDP), the speed is much better than vpn.

best regards.

norberto,
I expect a very good performance using ADS also through a VPN connection.
Does ADS transform a classic application into a client/server application?
Bye

Yes, all process is made in server side... but i dont have good results with browse (twbrowse) using very large database ( + 1 million registers) with vpn. without vpn, in lan, using ADS is very good, no more corruption, slow response, lack of security, transactions, ads solve this. but in vpn, (maybe i miss something) dont work for me, so i use RDP in internet. ads have an internet server, i dont try this, maybe solve this problem (browse).

Norberto,
many years ago when I used Clipper, ntx index files, ms-dos and Netware server and coaxial cables based lan.
I had many problems like corruption detected of ntx and dbf too.
I informed about ADS.
If I remember correctly browsing, reading of record contens are not client/server.
Only writing of database is client/server.
Probably, for this reasons, the performances are not so good.

Hi Marco,
I generally use Remote Desktop to connect different offices because it runs better then vpn with an instable connection (eg. UMTS-HSUPA),
anyway you have a consistent connection so you could make a vpn via amachi (it has a really high data compression) and make some tests with the standard dbf or (better) Sqlite3.
