查看出 ODS 使用率达到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
如何查找这个路径呢？
ps -ef | grep smon
会查找到 asm_smon_+ASM2
[oracle]$ export ORACLE_SID=+ASM2
[oracle] $ asmcmd
ASMCMD > lsdg
ASMCMD> cd data
ASMCMD > ls
ASMCMD > cd DATAFILE
ASMCMD> ls
发现了ods.539.784460919
增加数据文件 alter tablespace ODS add datafile ‘+DATA‘ size 8G;
(说明：直接加+DATA就可以，不用写/pgjt/datafile/ods.539.784460919，会自动生成。)
验证：用前面的方法还有查看系统日志
