random padlocks

Hi,

You should avoid SMB1 because of recently discovered security flaws. The WannaCry and Petya ransomware epidemics spread using the flaws in the SMB1 protocol.
Use the OmnisDataBridge instead.

Best regards,

Werner

You can also revert to SMB1 and turn off Write Back Cache.

I have posted a Studio Library to do this previously (Makes all the registry changes). I’m sure it could be converted into a Omnis7 App.

Simon,

What about using a ODB-OmnisDataBridge server ?

Will allow you to continue using DML & OmnisSQL(not a great fan of it) and you don’t have the locking problems you are confronted with.

We have been using it with O7 and 0$4 at the same time.

If you want we can share a small library which allow you to test the record locking of your setup.

Regards,

Marc
