oracle下表空间的导出,用户的删除,表空间删除,用户新建,表空间新建,数据导入的shell
使用非oracle用户执行该脚本
参数说名
$1:base表空间的用户名
$2:同步表空间的用户名
使用场景
测试用,base表空间用于升级建立一些固化数据。同步表空间用于测试用,每次去和base表空间拉平数据

#!/bin/sh
oraclehome=$ORACLE_HOME
echo $oraclehome
localdir="/oracle/data"
echo $localdir
#删除已经存在的临时dmp文件
rm -rf $localdir/$2temp.dmp
rmresult=$?
echo "rm $2temp.dmp result:$rmresult"
#将用户$1的表空间导出
su - oracle -c "exp dba/dba file=$localdir/$2temp.dmp owner=$1"
expresult=$?
if [ "$expresult" != "0" ];then
        echo "exp $1 tablespace failure!!!"
fi
#先删除用户$2及其表空间,然后再新建该用户及表空间
su - oracle -c "${ORACLE_HOME}/bin/sqlplus /nolog" <<EOF
connect / as sysdba
drop user $2 cascade;
drop tablespace $2 including contents and datafiles;
create tablespace $2 datafile &#39;/oracle/product/10.2.0/oradata/$2.dbf&#39; size 5M autoextend on;
create user $2 identified by "$2" default tablespace $2 temporary tablespace TEMP profile DEFAULT;
grant connect to $2;
grant resource to $2;
grant create any table to $2;
grant create any trigger to $2;
grant create any type to $2;
grant create any view to $2;
grant unlimited tablespace to $2;
exit
EOF
crdrresult=$?
if [ "$crdrresult" != "0" ];then
        echo "drop user and tablespace failure!!!"
        echo "create user and tablespace failure!!!"
else
#刚建完的用户不能马上使用,等候10秒
        sleep 10s
#更换dmp文件中的表空间名
        sed -i &#39;s/TABLESPACE "$1"/TABLESPACE "$2"/g&#39; $localdir/$2temp.dmp
#使用imp命令导出表空间数据到用户$2的表空间
        su - oracle -c "imp dba/dba file=$localdir/$2temp.dmp  fromuser=$1 touser=$2"
        impresult=$?
        if [ "$impresult" != "0" ];then
                echo "imp failure!!!"
        else
                echo "imp success!!!"
        fi
