Hi all,

I'm using Delphi 7.0 to build a database application using Oracle
and use a Direct Oracle Access 4.0.1.0 (DOA) component to connect to the database.

in a desgin time I set value to OCIDLL=c:\oracle\ora81\bin\oci.dll in the Parameters to complete the connection.

but when using application EXE file in another machine the connection not complete whrere as i can connect to the database from SQL*plus from the same new machine.

So, how can I start or Initialize OCIDLL with it's value in the run time.

Thanks,
khalid.

just left out this parameter,
doa will then retrieve self,
which dll is needed by evaluating the registry
(usual the oracle_home key)

Hi kretzschmar,
Hi DeerBear,

OCIDLL must be Initialized to connect either in the desgin time or in the run time.

if it is not initialize in the desgin time the connection don't Complete therefore i set
OCIDLL=c:\oracle\ora81\bin\oci.dll as a parameter

also in the run time it must be initailized to connect or an error message occure 'TNS can't resolve service name'.

thanks
khalid.
