Oracle 11g 第一次登录设备查看ORACLE_HOME , ORACLE_BASE , ORACLE_SID
1. 在oratab中查看SID的ORACLE_HOME目录
[oracle@localhost ~]$ cat /etc/oratab
#
# This file is used by ORACLE utilities. It is created by root.sh
# and updated by either Database Configuration Assistant while creating
# a database or ASM Configuration Assistant while creating ASM instance.
# 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.
#
#
