Help me maintain my sanity please.

There were memory issues with our internally written application running a batch job. They, proj mgr and business consultant, asked me to implement /3GB switch. There is some confusion about how this should be implemented. I thought that you had to make changes to the O/S on the database server by editing the boot.ini file and make changes to some of the Oracle database parameters. The proj mgr and business consultant feel that you only have to make changes to the O/S on the client machine by editing the boot.ini where the application is stored. I'm outnumbered 2 to 1 so the latter solution has prevailed. What is correct?

Thanks in advance.
