Multi-user Paradox

Hi,

We have a single user desktop application using Paradox as database. Now we want to convert that application as multi-user application but using Paradox itself, can any one assist me in doing the same. What all the things I need to consider both from coding perspective and database perspective. Thanks in advance.

hi,

nothing else to do (except you have special codings),
except to configure the bde properly for each client,
whereas the net-dir entry must be pointed to a shared network-drive (exact the same entry for each client)
in the paradox-driver tab of the bde-admin
and the dbdir must be pointed to a shared dir (exact the same entry for each client) in the alias defintion.

Thanks meikl for your inputs, my concern is about handling multiple database updates, i'm using locktable, but when more than two people are accessing the database, clients are getting stucked. What I've done is, wrote to functions one to lock and another to unlock the table.

If suppose say two users are trying to update database, whoever gets the lock will continue with database updatations, other users will wait until lock is realsed. When the first user releases the lock using unlocktable, other waiting users get their chance to update the database.

But the above logic is working fine for two users, but when the users are more than two, all clients are stuck.

can u please guide me in this regards

If you don't know how to configure a bde client on another pc, you should try InstallShield Express - shipped with delphi.

And a second thing - Remember to use 'transaction' - otherwise the database may get corrupted very easily !!

hi again,

u do not need to use locktable,
because the paradox-engine does automatically a
record-locking. so that users are able to edit records in the same table but not the same record.
