Hi,
You can try with ODBC protocol and Oracle 2-Tier.
Additional options could be Windows Sockets or .Net protocol if the application is compiled or it could be recompiled in "AnyCPU" mode only. Please check in LR 11.52 PAM.
The protocols which support 64bit recording are listed in LoadRunner 11.52 readme.
When you click on a protocol in the Create a new Script window you will get basic information when the protocol is used.
Kind regards,
