一次增加表空间的过程

1、统计数据库的剩余的使用空间

SELECT tablespace_name,
trunc ( sum (bytes ) / (1024*1024) ) as free_m,
sum ( blocks ) as free_blk ,
max ( bytes ) / (1024) as big_chunk_k,
count (*) as num_chunks
FROM dba_free_space
GROUP BY tablespace_name ;

结果：

TABLESPACE_NAME FREE_M FREE_BLK BIG_CHUNK_K NUM_CHUNKS
------------------------------ ---------- ---------- ----------- ----------
PSAPUNDO 6064 776280 2127872 11
SYSAUX 6 880 7040 1
PSAPSR3 3224 412752 673728 8
PSAPSR3USR 10 1384 11072 1
SYSTEM 1229 157320 1258432 2
PSAPSR3700 5759 737248 865216 12

2、需要增加SYSAUX空间

select file_name,bytes/1024/1024 from dba_data_files where tablespace_name like '%SYS%';

FILE_NAME BYTES/1024/1024
---------------------------------------------------------------------------------------------------------
E:\ORACLE\PII\SAPDATA1\SYSTEM_1\SYSTEM.DATA1 1000

E:\ORACLE\PII\SAPDATA1\SYSAUX_1\SYSAUX.DATA1 200

3、找到表空间文件

ALTER DATABASE DATAFILE 'E:\ORACLE\PII\SAPDATA1\SYSAUX_1\SYSAUX.DATA1' RESIZE 2G;

4、检查一下增加的情况

SELECT tablespace_name,
trunc ( sum (bytes ) / (1024*1024) ) as free_m,
sum ( blocks ) as free_blk ,
max ( bytes ) / (1024) as big_chunk_k,
count (*) as num_chunks
FROM dba_free_space
GROUP BY tablespace_name ;

结果：

TABLESPACE_NAME FREE_M FREE_BLK BIG_CHUNK_K NUM_CHUNKS
------------------------------ ---------- ---------- ----------- ----------
PSAPUNDO 6064 776280 2127872 11
SYSAUX 1854 237392 1899136 1
PSAPSR3 3224 412752 673728 8
PSAPSR3USR 10 1384 11072 1
SYSTEM 1229 157320 1258432 2
PSAPSR3700 5759 737248 865216 12

万事大吉，sysaux空间已足够打了。。。
