Oracle环境变量设置脚本

每次都傻乎乎的往bashrc里面写环境变量，感觉不任性。于是，看了本书了解了/etc/oratab这个东东后，参考着书也写了一个设置Oracle环境变量的脚本。

在/etc/下创建oraset,权限设置为chown oracle:oinstall /etc/oraset

oraset内容：

#!/bin/bash
# Sets Oracle environment variables.
# Setup: 1. Put oraset file in /etc(Linux), in /var/opt/oracle(Solaris)
#        2. Ensure /etc or /var/opt/oracle is in $PATH
# Usage: batch mode: . oraset <SID>
#        menu mode: . oraset
#=======================================================
if [ -f /etc/oratab ]; then
    OTAB=/etc/oratab
elif [ -f /var/opt/oracle/oratab ]; then
    OTAB=/var/opt/oracle/oratab
else
    echo ‘oratab file not found.‘
    exit
fi
#
if [ -z $1 ]; then
    SIDLIST=$(egrep -v ‘#|\*‘ ${OTAB} | cut -f1 -d:)
    # PS3 inmdicates the prompt to be used for the Bash select command.
    PS3=‘SID?‘
    select sid in ${SIDLIST}; do
        if [ -n $sid ]; then
            HOLD_SID=$sid
            break;
        fi
    done
else
    if egrep -v ‘#|\*‘ ${OTAB} | grep -w "${1}:">/dev/null; then
        HOLD_SID=$1
    else
        echo "SID: $1 not found in $OTAB"
    fi
    shift
fi
#
ORACLE_SID=$HOLD_SID
export ORACLE_SID
export ORACLE_HOME=$(egrep -v ‘#|\*‘ ${OTAB} | grep -w $ORACLE_SID:|cut -f2 -d:)
export ORACLE_BASE=${ORACLE_HOME%%/product*}
export TMP=$ORACLE_BASE/../tmp
export TMPDIR=$TMP
export TNS_ADMIN=$ORACLE_HOME/network/admin
export ADR_BASE=$ORACLE_BASE/diag
export PATH=$PATH:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib

然后在oracle用户的.bashrc里面添加：

source /etc/oraset xxxx

注：

1. xxxx为你SID的名称。

2. 路径以个人安装为准。

3. 谁知道怎么在Live Writer的代码亮度插件里添加行号和奇偶行不同色？
