I haven't been a developer for sudo for...jeez...a decade now.
And I no longer maintain a great galumphing glob of Unix machines,
so the needs I have these days for sudo are simple enough that
I'm not familiar with "new" syntax in sudoers like env_delete.
I've therefore cc'ed your msg to the sudo-users mailing list,
where I'm sure somebody can help you out.
My ignorance of env_delete aside, I'm certain you can just
enable the running of wrapper script in sudoers that looks
exec env LD_LIBRARY_PATH=$DB2LIB LIBPATH=$DB2LIB $START_WEBSPHERE
where the DB2LIB & START_WEBSPHERE vars are set appropriately.
This would work just fine if those vars have a static setting,
by which I mean the vars are the same for all users who need
to start WebSphere via sudo.
