rebuild index online的指令範例語法如下:
(1)在原來的Tablespace rebuild
ALTER INDEX index_name REBUILD ONLINE;
(2)rebuild 到另一個Tablespace
ALTER INDEX index_name REBUILD TABLESPACE tablespace_name ONLINE;
(3)add file 到Tablespace
注意事項：
一、須注意避開DB忙碌時間即可 ex. 晨午報產生時間
二、注意最大的index_name需大於剩餘空間
三、Rebuild到另一個tablespace，還需要在rebuild回原來的tablespace，所以要做兩次，但效果比較好
四、Archive log空間會變大，注意事否空間足夠
五、Tablespace Temp空間也會變大，也要注事是否足夠空間
一、查詢前十大的index_name
SELECT * FROM (SELECT OWNER, SEGMENT_NAME INDEX_NAME, BYTES/1024/1024 MB from dba_segments where tablespace_name='STGC5_IDX' order by BYTES DESC) WHERE rownum<10;
註：最大為12.5G，小於目前最大26G，可以做Rebuild
產生rebuild語法：
ALTER INDEX STGC5.GROUPHIST_0E8E REBUILD TABLESPACE STGC5_IDX ONLINE;
要打十個太累，自動產生語法：
SELECT * FROM (SELECT 'ALTER INDEX ' || OWNER || '.' || SEGMENT_NAME || ' REBUILD TABLESPACE ' || TABLESPACE_NAME || ' ONLINE;' from dba_segments where tablespace_name='STGC5_IDX' order by BYTES DESC) WHERE rownum < 10;
寫成一個sql，自動全部執行：
[oracle@c5rptdb1 script]$ cat index_rebuild_stgc5.sql
alter session set NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS";
--設定時間格式
set linesize 110
--設定顯示寬度
set timing on
--啟動計時
spool index_20130514.log
--產生log file
select sysdate from dual;
--顯示現在時間
PROMPT rebuild 1/10...
--列印目前執行項目
ALTER INDEX STGC5.PKFWAMTCOMPTRACKHISTORY REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 2/10...
ALTER INDEX STGC5.GROUP_HIST_ 7F 1A REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 3/10...
ALTER INDEX STGC5.TXNTIMECOMMENT_ 7F 1A REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 4/10...
ALTER INDEX STGC5.IDANDTIMESTAMP_ 7F 1A REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 5/10...
ALTER INDEX STGC5.LOTOBJTXNTIME_0E94 REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 6/10...
ALTER INDEX STGC5.PKFWWIPHISTORY_N 2M REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 7/10...
ALTER INDEX STGC5.WIPTXN_0E8E REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 8/10...
ALTER INDEX STGC5.PKFWWIPTRANSACTION REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 9/10...
ALTER INDEX STGC5.PKFWWIPHISTORY REBUILD TABLESPACE STGC5_IDX ONLINE;
PROMPT rebuild 10/10...
ALTER INDEX STGC5.GROUPHIST_0E8E REBUILD TABLESPACE STGC5_IDX ONLINE;
select sysdate from dual;
--顯示結束完的時間
spool off;
--關閉
exit;
--離開
執行方式：
[oracle@c5rptdb1 script]$ sqlplus / as sysdba

SQL> @index_rebuild_stgc5.sql
註：Index Rebuild完之後，再確認一下空間是否有釋放出來，若沒有，代表這一段時間很少在做delete的動作，大部份都是add資料，所以釋放的空間不大。
選擇Add tablespace file
填入Tablespace Name
增加DataFiles
SQL語法：
CREATE TABLESPACE STGC5_IDX_TMP DATAFILE
'/rptdata1/c5prpt/STGC5_IDX_TMP_01.dbf' SIZE 1024M AUTOEXTEND ON NEXT 100M MAXSIZE 31744M
LOGGING
PERMANENT
EXTENT MANAGEMENT LOCAL AUTOALLOCATE
BLOCKSIZE 8K
SEGMENT SPACE MANAGEMENT MANUAL
FLASHBACK ON;
開始搬移資料到新的TABLESPACE，一樣選擇前十大的index_name ==>STGC5_IDX會清出空間
ALTER INDEX STGC5.PKFWAMTCOMPTRACKHISTORY REBUILD TABLESPACE STGC5_IDX_TMP ONLINE;
做完之後再搬移到舊的TABLESPACE ==> tablespace STGC5_IDX_temp 會變成空的
ALTER INDEX STGC5.PKFWAMTCOMPTRACKHISTORY rebuild TABLESPACE STGC5_IDX online;
再把 tablespace STGC5_IDX_temp 刪除掉
Drop tablespace STGC5_IDX_TMP including contents;
一樣是在Tablespace的位置下，新增file
照上面看到的資訊增加File
DataFile:預設OS使用的空間，增加1g的空間
Auto Extend:下次若空間滿了，增加allocate的空間，100mb
Maximum:最大的空間佔多大，使用31G，( 32G會出錯)
Sql語法：
ALTER TABLESPACE STGC5_IDX ADD DATAFILE '/rptdata1/c5prpt/STGC5_IDX_05.dbf' SIZE 1024M AUTOEXTEND ON NEXT 100M MAXSIZE 31744M;
