请高手指点AIX下安装oracle时设定环境变量内容的意思

sgy5621871

最近看AIX下安装oracle时看见设定的环境变量为：
修改oracle用户的.profile环境变量文件，增加以下内容：
ORACLE_BASE=/oracle; export ORACLE_BASE
ORACLE_HOME=/oracle/OraHome1; export ORACLE_HOME
ORACLE_SID=ora9i; export ORACLE_SID
ORACLE_TERM=vt100; export ORACLE_TERM
TNS_ADMIN=$ORACLE_HOME/network/admin;export TNS_ADMIN
NLS_LANG=american_america.zhs16cgb231280; export NLS_LANG
ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data; export ORA_NLS33
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib; export LD_LIBRARY_PATH
LIBPATH=$ORACLE_HOME/libORACLE_HOME/ctx/lib ;export LIBPATH
ORA_DB=$ORACLE_HOME/dbs;export ORA_DB
#CLASSPATH=$ORACLE_HOME/jlib;  ORACLE_HOME/rdbms/jlib
CLASSPATH=$ORACLE_HOME/JRE/libORACLE_HOME/JRE/lib/rt.jarCLASSPATH
export CLASSPATH
PATH=$ORACLE_HOME/binPATH; export PATH
DISPLAY=:0.0; export DISPLAY
但不知道这里面每一步设的都是什么意思，哪位高手能帮忙讲解一下吗？谢谢
