給表空間增加數據文件，存儲在ASM

**管控  10.1.80.174  實例名PGJT2，表空間為ODS已經滿了，申請增加數據文件。

col tablespace_name for a15;

select d.tablespace_name,space "sum_space(m)",blocks sum_blocks,space-nvl(free_space,0) "used_space(m)",

round((1-nvl(free_space,0)/space)*100,2) "used_rate(%)",free_space "free_space(m)"

from dba_free_space                                                                                     

group by tablespace_name) f                                                                            

where d.tablespace_name = f.tablespace_name(+) union all                                               

select d.tablespace_name,space "sum_space(m)",blocks sum_blocks,                                       

used_space "used_space(m)",round(nvl(used_space,0)/space*100,2) "used_rate(%)",

------------ASM-----------------------------

select NAME,TOTAL_MB,FREE_MB from v$asm_diskgroup;

查看出 ODS    使用率達到99%      ，DATA 剩余1.3T

Select  file_name,tablespace_name ,status from dba_data_files where tablespace_name=’ODS’;

FILE_NAME                            TABLESPACE_NAME          STATUS

+DATA/pgjt/datafile/ods.539.784460919        ODS                    AVAILABLE

如何查找這個路徑呢？

ps  -ef | grep  smon

會查找到 asm_smon_+ASM2   

[oracle]$ export  ORACLE_SID=+ASM2

[oracle] $ asmcmd

ASMCMD > lsdg

ASMCMD> cd  data

ASMCMD > ls

ASMCMD > cd  DATAFILE

ASMCMD> ls

發現了ods.539.784460919

增加數據文件   alter tablespace ODS add datafile ‘+DATA‘  size 8G;

(說明：直接加+DATA就可以，不用寫/pgjt/datafile/ods.539.784460919，會自動生成。)

驗證：用前面的方法還有查看系統日志
