Create partition Table/Index

Create partition Table/Index：

1. 確認是否需要新增Table/Index Tablespace

2. 確認空間是否足夠

3. Create Partition table

4. Split Partition

5. Create Partition Index

6. 確認建立的Partition(找出最大的Partition)

一、產生新的 Table/index Tablespace語法(自行確認是否要新增)：

CREATE TABLESPACE STGC5_TRG_2015Q1 DATAFILE

'/rptdata1/c5prpt/STGC5_TRG_2015Q1_01.dbf' SIZE 500M AUTOEXTEND ON NEXT 100M MAXSIZE 32000M,

'/rptdata2/c5prpt/STGC5_TRG_2015Q1_02.dbf' SIZE 500M AUTOEXTEND ON NEXT 100M MAXSIZE 32000M,

'/rptdata3/c5prpt/STGC5_TRG_2015Q1_03.dbf' SIZE 500M AUTOEXTEND ON NEXT 100M MAXSIZE 32000M,

'/rptdata4/c5prpt/STGC5_TRG_2015Q1_04.dbf' SIZE 500M AUTOEXTEND ON NEXT 100M MAXSIZE 32000M

LOGGING

ONLINE

PERMANENT

EXTENT MANAGEMENT LOCAL AUTOALLOCATE

BLOCKSIZE 8K

SEGMENT SPACE MANAGEMENT AUTO

FLASHBACK ON;

二、確認Tablespace空間大小：

select t.tablespace_name ,avg(d.bytes/d.maxbytes)*100 as Used_Rate,sum(d.maxbytes)/1024/1024/1024 as max_g,sum(d.bytes)/1024/1024/1024 as Used_g,

(sum(d.maxbytes)-sum(d.bytes))/1024/1024/1024 as free_space_g

FROM DBA_TABLESPACES T,DBA_DATA_FILES D

WHERE T. TABLESPACE_NAME =D. TABLESPACE_NAME and d.maxbytes!=0 group by t.tablespace_name

ORDER BY Free_space_g

三、增加Partition Table:

1.日期格式：

select 'ALTER TABLE '||TABLE_OWNER||'.'||TABLE_NAME||' ADD PARTITION P2015Q1 VALUES LESS THAN (''20150401 000000'') TABLESPACE DWC5_TBL;'

from dba_tab_partitions t where table_owner='DWC5' AND PARTITION_NAME='P2014Q1';

結果：

ALTER TABLE DWC5.CUT_TIME_WIP ADD PARTITION P2015Q1 VALUES LESS THAN ('20150401 000000') TABLESPACE DWC5_TBL;

2.時間格式：

select 'ALTER TABLE '||TABLE_OWNER||'.'||TABLE_NAME||' ADD PARTITION P2015Q1 VALUES LESS THAN TO_DATE('' 2015-04-01 00:00:00'', ''SYYYY-MM-DD HH24:MI:SS'', ''NLS_CALENDAR=GREGORIAN'') TABLESPACE DWC5_TBL;'

from dba_tab_partitions t where table_owner='DWC5' AND PARTITION_NAME='P2014Q1';

結果：

ALTER TABLE DWC5.CUT_TIME_WIP ADD PARTITION P2015Q1 VALUES LESS THAN TO_DATE(' 2015-04-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN') TABLESPACE DWC5_TBL;

四、Split Partition

SELECT 'ALTER TABLE '||TABLE_OWNER||'.'||TABLE_NAME||' SPLIT PARTITION CTHI_MAXVALUE (TO DATE(''20170101 000000'') INTO (PARTITION '

||PARTITION_NAME|| ', PARTITION CTHI_MAXVALUE TABLESPACE) ' ||TABLESPACE_NAME|| ';' from dba_tab_partitions t

where table_owner='C5PROD' AND PARTITION_NAME LIKE '%2015Q4';

結果：

ALTER TABLE C5PROD.FWAMTCOMPTRACKHISTORY SPLIT PARTITION CTHI_MAXVALUE (TO DATE('20170101 000000') INTO (PARTITION CTHI_2015Q4, PARTITION CTHI_MAXVALUE) TABLESPACE C5_PTT_CTHI10;

五、增加Partition Index

每季增加：

SELECT * FROM (SELECT 'ALTER INDEX ' || OWNER || '.' || SEGMENT_NAME || ' REBUILD PARTITION P2015Q4 TABLESPACE= ' || TABLESPACE_NAME || ';' from dba_segments

where tablespace_name='DWC5_IDX' AND PARTITION_NAME='P2014Q4');

結果：

ALTER INDEX DWC5.XPKCUT_TIME_WIP_P REBUILD PARTITION P2015Q4 TABLESPACE= DWC5_IDX;

一次找出一整年(Partition table要先建立好)：

SELECT 'ALTER INDEX ' || INDEX_NAME || ' REBUILD PARTITION '||PARTITION_NAME|| ' TABLESPACE '||TABLESPACE_NAME|| ';'

FROM ALL_IND_PARTITIONS WHERE INDEX_OWNER='STGC5' AND PARTITION_NAME LIKE '%2014Q%';

結果：

ALTER INDEX IDX_COMPDLTYPETIME_600A REBUILD PARTITION P2014Q1 TABLESPACE STGC5_TRG_IDX_2014Q1;

六、找出最大的Partition：

SELECT INDEX_NAME,max(PARTITION_NAME) FROM ALL_IND_PARTITIONS WHERE INDEX_OWNER='STGC5' group by INDEX_NAME order by max(PARTITION_NAME);

DB File/Tablespace Size Monitor

查看每個File的使用率
SELECT T.TABLESPACE_NAME,D.FILE_NAME,D.AUTOEXTENSIBLE,D.BYTES/1024/1024/1024 as USED_G,D.MAXBYTES/1024/1024/1024 AS MAX_G,D.STATUS,(d.bytes/d.maxbytes)*100 AS UseRate
FROM DBA_TABLESPACES T,DBA_DATA_FILES D
WHERE T. TABLESPACE_NAME =D. TABLESPACE_NAME and d.maxbytes!=0 ORDER BY UseRate desc

查看Tablespace的平均使用率及剩餘空間
select t.tablespace_name ,avg(d.bytes/d.maxbytes)*100 as Used_Rate,sum(d.maxbytes)/1024/1024/1024 as max_g,sum(d.bytes)/1024/1024/1024 as Used_g,
(sum(d.maxbytes)-sum(d.bytes))/1024/1024/1024 as free_space_g
FROM DBA_TABLESPACES T,DBA_DATA_FILES D
WHERE T. TABLESPACE_NAME =D. TABLESPACE_NAME and d.maxbytes!=0 group by t.tablespace_name
ORDER BY Free_space_g

JOB Lock & job_queue_processes

系統出現ORA-00054: resource busy and acquire with NOWAIT specified，時間點約在22:00:36分，猜測應該是在做Analysis的時候，有lock住檔案。

1.Check Job是否在Running

2.Stop job

3.Kill job session

4.Check job status

5.Start Job

若不讓job暫時啟動起來：

1.Check Jobs啟動數量

2.job_queue_processes = 0;

3.工事處理完之後，job_queue_processes = original_value;
