ORA-1652错误模拟测试

简单模拟错误的过程如下：
SQL> truncate table test1;

Table truncated.

SQL> insert into test1 select * from dba_objects;

49749 rows created.

SQL> commit;

Commit complete.

SQL> insert into test1 select * from test1;

49749 rows created.

SQL> /

99498 rows created.

SQL> /

198996 rows created.

SQL> commit;

Commit complete.

SQL>
SQL>
SQL> insert into test1 select * from test1;

397992 rows created.

SQL> /

795984 rows created.

SQL> commit;

Commit complete.

SQL>
SQL> select count(*) from test1;

  COUNT(*)
----------
   1591968

SQL> insert into test1 select * from test1;

1591968 rows created.

SQL> commit;

Commit complete.

SQL> insert into test1 select * from test1;
insert into test1 select * from test1;
            *
ERROR at line 1:
ORA-01653: unable to extend table DBSEEK.TEST1 by 1024 in tablespace TBS1652
ORA-06512: at line 3
SQL> alter database  datafile '/oracle/oradata/orcl/tbs1652_01.dbf' resize 800M;

Database altered.

SQL> alter table test1 move;

alter table test1 move

再开一个session 来检查当前的临时表空间
此时临时表空间里面运行的会话信息：
USERNAME          SID    SERIAL# OSUSER          TABLESPACE     BLOCKS
---------- ---------- ---------- --------------- ---------- ----------
SQL_TEXT
----------------------------------------------------------------------
DBSEEK            159          5 oracle          TEMP             6656
CREATE INDEX idx_test1_id ON test1(owner,object_id) tablespace tbs1652


临时段的使用情况
TABLESPACE TOTAL_BLOCKS USED_BLOCKS FREE_BLOCKS
---------- ------------ ----------- -----------
TEMP              11904       11904        0


SQL> alter database tempfile '/oracle/oradata/orcl/temp01.dbf' resize 200M;

Database altered.


SQL> CREATE INDEX idx_test1_id ON test1(owner,object_id) tablespace tbs1652;

Index created.

总结：

1.使用临时段的操作：
 排序操作 比如select或dml(ddl)语句中包含order by之类;
 create index
 create pk constraint (其实这个跟create index类似，因为创建主键约束时默认会同时创建index)
 enable constraint操作
 create table语句
 bitmap index
 hash join

2.ORA-1652的解决方法：

解决方法是，1加大临时表空间，2是找到临时表空间使用过大的原因，优化SQL语句，尽量降低排序操作
