In order to get set -o vi
This should be set at the .kshrc or .bashrc level

# use emacs editing mode by default
# set -o emacs

#        environment variable must be set.
#
# Notes: If this script is invoked from a terminal session,

# Exit Status:  99 = Required input, $ORACLE_SID, not supplied.
#               90 = Invalid Oracle sid.
#               95 = init.ora file not found for input sid.
#               97 = Alert log file does not exist.
