Hi

I use Win7 64bit. First installed client and pl/sql Developer works. Today had to install DB in other home and cannot connect to any DB - Initialization error - oci.dll - returned 0.


Running from batch file :

set PATH=%ORACLE_HOME%\bin
set TNS_ADMIN=\\orlik\Onames
"C:\Program Files (x86)\PLSQL Developer\plsqldev.exe" prefpath=e:\inne\plsqlPreferences



--- Info ---

PL/SQL Developer
Version 8.0.4.1514
295.69589 - Unlimited user license
Windows 7 (64-bit) 6.1 Build 7601 (Service Pack 1)

Physical memory : 4

Can you go to Help > Support Info, press the 'Copy all pages' button on this info screen, and paste this text into an e-mail reply?

Did You get Support Info in email ?

I don't think so. Can you resend it?

Thanks, received. Can you confirm that your OraClient11g_home1 is a 32 Bit Oracle Client?

It is Oracle_11gR2_client_win64
DB also

You will need to install a 32 Bit Oracle11g Client. PL/SQL Developer is a 32 Bit application, so it 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.

It is working now (after installing instant client 32 bit), but it was also working before installing DB. Never mind, thanks for help.
