# 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:N|Y>:
#
# 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.
