RedHat Remoting sudo commands & bypassing bashrc

What I want to do is not unique, except that our environment has a twist.

I want to ssh to a remote server and issue a sudo command to run a script. This isn't working, but you'll get the gist.
Code:
# ssh remotehost sudo -i -u oracle script.bash

The sudo to oracle is fine. The script.bash sets up the environment variables needed to run the Oracle commands and runs a very rudimentary "asmcmd lsdg" to get information.

The problem is that the Oracle user's .bashrc or .bashprofile which gets executed by the "sudo -i -u" has a shell menu that prompts the logged on user (99% of the time it's oracle) to select some variables before dumping the session to a shell prompt. Since I'm scripting the commands to source my environment then run the Oracle commands, and running it via cron, I have to be able to ignore the menu from the profile.

As root (or even myself), I can't source the env variables from Oracle and run the script (no DB perms), so that option is out.

Is there any way I can use sudo or su on the remote system and bypass or break out of the bashrc to ignore the menu prompting so I can run my script seamlessly?

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
chkconfig(8), ntsysv(8), systemd(1), systemctl(8), systemd.service(5) Jan 2006 service(8)
