@Rene : Yes the sqlnet and tnsnames.ora files are same in both 32bit and 64bit oracle client.

i tried setting ORACLE_HOME and TNS_ADMIN env variables both at user and system level, bit still getting this error. Any specific config I need to put in the app.ini file ?

Do you resolve Oracle connection identifier using tnsnames.ora?

Do you have same settings for this file in 32 and 64 bit oracle client?

Check your settings for ORACLE_HOME.

... or set the TNS_NAMES environment variable to point to the directory where you TNSNAMES.ORA file is.

regards.
