Resolution
Verify if the machines that you are having problems connecting with have multiple installs/homes of Oracle.
If so, then Benchmark Factory will load the Oracle OCI libraries which are first found in the PATH environment variable.
For example:
If you have both 10G and 11G clients on your workstation and the first one in "PATH" is 11g while TNSNAMES.ORA file was located in 10.2 only, then please copy it to 11G.
