ORA_PASSWD should be set to the password assigned to the database account associated with the user name specified by ORA_LOGIN.
Example
If the account with the user name has the associated password CW021535, you would specify:
ORA_PASSWD CW021535
in the ACUFH configuration file or the environment.
For a full login from a client to a remote server, you could have either of the following two settings:
ORA_LOGIN username ORA_PASSWD userpass A_ORA_DATABASE remotesrv
or
ORA_LOGIN username@remotesrv ORA_PASSWD userpass
In this example, remotesrv is the net service name you have set up, as defined in A_ORA_DATABASE configuration variable.
