# rootpre.sh
#
# This script is intended to be run by root before ORACLE_OWNER runs
# the Installer to install ORACLE products.
#
# This script should be run by root from the directory where this script
# resides. If root wishes to run this script from another directory,
# then root must set the environment variable is ROOTPRE_DIR (see below).
#
# rootpre.sh performs configuration tasks for 3 AIX components:
# - Asynchronous I/O subsystem s made available
# - sets permissions on HACMP and PSSP sockets
#
#
# ENVIRONMENT:
#
# LOG
# If root wishes to log diagnostic output generated by this script,
# set environment variable LOG to the pathname of the log file.
#
# ROOTPRE_DIR
# If root wishes to run rootpre.sh from a directory other than that
# in which rootpre.sh resides, set ROOTPRE_DIR to the directory where
# rootpre.sh resides.
