自動重建失效index的shell指令碼

自動重建失效index的shell指令碼
指令碼每一個小時執行一次，檢測失效索引，一旦發現立刻重建
指令碼全部內容如下：
[oracle@orac1 pump]$ more /home/oracle/tools/rebuild_index.sh

#Enviroment define.
source /home/oracle/tools/SET_JOB_ENV.sh
export PATH=$PATH

#following is excution part
sqlplus / as sysdba <<eof
declare
begin
  for i in (select index_name,owner from dba_indexes where status ='UNUSABLE' and wner='EDW1_USER') loop
    execute immediate 'alter index '||i.owner||'.'||i.index_name||' rebuild online';
  end loop;
  for j in (select index_name,partition_name,index_owner from dba_ind_partitions where status ='UNUSABLE' and index_owner='EDW1_USER') loop
    execute immediate 'alter index '||j.index_owner||'.'||j.index_name|| ' rebuild partition '||j.partition_name||' online';
  end loop;
end;
/
exit
eof

其中為環境變數設定指令碼為
[oracle@orac1 pump]$ more /home/oracle/tools/SET_JOB_ENV.sh
PATH=$PATH:$HOME/bin
export PATH
unset USERNAME
#oracle env
ORACLE_BASE=/data/oracle
ORACLE_HOME=$ORACLE_BASE/product/10.2/db1

export ORACLE_BASE ORACLE_HOME

export CLASSPATH
