Hi,

Is DOA supports Oracle Wallet concept?

If you configure your Oracle Client correctly it should be transparent. You can logon by omitting the username and password.

you mean to say existing DOA components will work normally with out any changes with regards to Oracle wallet. only thing i have to consider is username and password is not being entered explicitly. have to pass the logged in windows user details to oracle for authentication.

If you have configured the Oracle Client correctly you can omit the username and password during Oracle Log on.

thanks marco. you mean to say no username and password needs to be entered. will it take from sqlnet.ora file and corresponding certificates?

Yes, that is how the Oracle Client will do it.
