Oracle 11g Windows registry not foud

[Zugg]

Hello,

I have installed Oracle 11g : 11.1.0.7.0 64 bits en windows 2008 server and it seems that DOA components (4.1.2.0) and PL/SQL developper (7.1.5.1398) are visibly not able to found the Oracle path in windows registry : error when starting PL/SQL developper, and Access violation in OracleSession and OracleAliasList is empty.

TNSPING works fine and I am able to connect to my database with sqlplus.

My application is developped in Delphi 2009.

Could you tell me if DOA and PL/SQL developper are compatible with this Oracle version and why it is not working.

Thanks.

You will need to install a 32 Bit Oracle Client. PL/SQL Developer and Delphi/C++Builder are 32 Bit applications, so they cannot interface with a 64 Bit Oracle Client.

The 32 Bit Oracle Client can communicate with a 64 Bit Server, even on the same machine if necessary. The 32 Bit client can coexist with a 64 Bit Oracle installation when installed in separate Oracle Home directories.

Hello Marco,

Thanks for your reply.

So if I understand, in 64 bits architecture I must allways install a 32 bits Oracle client to enable my application and PL/SQL developper to work properly.

I thought that Windows will do this job : enable 32 bits application to dialog with 64 bits application.

Is this limitation due to DOA or Delphi ?

Thanks.

32 bits applications can run on a 64 bits Operating System, but a 32 bits application cannot interface with a 64 bits DLL. This is a general limitation, and is not limited to Direct Oracle Access or Delphi.

ok, thanks for this precision Marco.
