# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME::
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.

# This routine is used to condition a Bourne shell user's environment
# for access to an ORACLE database. It should be installed in
# the system local bin directory.
#
# The user will be prompted for the database SID, unless the variable
# ORAENV_ASK is set to NO, in which case the current value of ORACLE_SID
# is used.
# An asterisk '*' can be used to refer to the NULL SID.
#
# 'dbhome' is called to locate ORACLE_HOME for the SID. If
# ORACLE_HOME cannot be located, the user will be prompted for it also.
# The following environment variables are set:
#
# ORACLE_SID Oracle system identifier
# ORACLE_HOME Top level directory of the Oracle system hierarchy
# PATH Old ORACLE_HOME/bin removed, new one added
# ORACLE_BASE Top level directory for storing data files and
# diagnostic information.
#
# usage: . oraenv
#
# NOTE: Due to constraints of the shell in regard to environment
# ----- variables, the command MUST be prefaced with ".". If it
# is not, then no permanent change in the user's environment
# can take place.
