ORACLE RAC中grid和oracle中环境变量设置和相关命令使用原则

环境变量的具体设置如下，主机ORACLE_HOME的不同

[grid@dtydb3 ~]$ id
uid=601(grid) gid=501(oinstall) groups=501(oinstall),502(dba),503(oper),504(asmadmin),506(asmdba),507(asmoper)
[grid@dtydb3 ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

ORACLE_SID=+ASM1; export ORACLE_SID
ORACLE_BASE=/oracle/app/grid; export ORACLE_BASE
ORACLE_HOME=/oracle/11.2.0/grid; export ORACLE_HOME
GRID_HOME=/oracle/11.2.0/grid; export GRID_HOME
THREADS_FLAG=native; export THREADS_FLAG
PATH=$ORACLE_HOME/bin:$PATH; export PATH
if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
export LANG="en_US.UTF-8"

[root@dtydb3 ~]# su - oracle
[oracle@dtydb3 ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

ORACLE_BASE=/oracle/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
ORACLE_SID=tyolap1; export ORACLE_SID
export ORACLE_UNQNAME=tyolap
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
export LANG="en_US.UT

     设置的原则和相关命令的使用原则如下：

If you use ASMCMD, srvctl, sqlplus, or lnsrctl to manage Oracle ASM or its listener, then use the binaries located in the Grid home, not the binaries located in the Oracle Database home, and set the ORACLE_HOME environment variable to the location of the Grid home.

    如果使用ASMCMD, srvctl, sqlplus, or lnsrctl命令去管理ASM和它的监听使用grid用户执行grid home下相关命令
    If you use srvctl, sqlplus, or lnsrctl to manage a database instance or its listener, then use the binaries located in the Oracle home where the database instance or listener is running, and set the ORACLE_HOME environment variable to the location of that Oracle home
 如果使用srvctl, sqlplus, or lnsrctl管理数据库实例相关命令，则使用oracle用户只需oracle home下的相关命令
