Hi,

There is an issue with the 32 bit Oracle client on 64 bit windows where it cannot connect to the database throwing the error ORA-12154: TNS:could not resolve the connect identifier specified.

Since all the 32 applications will have the path C:\Program Files (x86) on 64 bit windows, The PATH variable doesnt recognise (). This issue was there in the previous versions of Oracle Client. But the bug has been fixed in Oracle 10.2.0.3 32 bit client. Still the user is facing the same issue. Could you please suggest any patch or solution for this?

Oracle Client: 10.2.0.3 32 bit

Windows OS: Windows server 2008 R2 64 bit


I have referred document [ID 334528.1] from the metalink(which states that the bug is fixed in 10.2.0.3 client).

Could you please suggest any patch for this issue.

Thanks in Advance.

No idea, but - did you try to enclose directory name into double quotes?

Besides, why did you install Client software into the "Program Files (x86)" directory? Why didn't you put it somewhere else, such as "c:\oracle\client_10" (i.e. the one that doesn't contain spaces, brackets and similar characters)?

We had similar problems with 32 bit SQL Servers connection to Oracle.

It only worked after both the Client and Server were on 10.2.0.4
