asp classic - How to work with 32 and 64 bit DSN Simultaneously? -


my application in classic asp. till working fine 32bit windows server , connecting oracle via system dsn prepared "microsoft odbc driver oracle". now, server has been migrated 64bit windows server 2008 r2. have third party dlls, have 64bit available. so, deploy application in iis 7.5 , working fine.

in new server, using oracle driver, 64bit, there no driver of "microsoft odbc driver oracle". working fine, except, when try fetch record-set, returning nothing. no error message, no data, nothing coming.

also, can't change app pool compatibility 32 bit "true", because, there third-party component work in either of 1 environment. either 32 bit or 64 bit.

so, concern is, whether can work both dsn[32 , 64]? or other idea run application.

could use oledb driver instead. oracle provide 64 bit oledb driver, , installed on server already.

odbc isn't regarded best way go, unless you're using mysql when it's pretty option
