近期学习进行压力测试，由于大批量导入数据，Oracle数据库引起ORA-01653: unable to extend table错误，原因是TABLESPACE没有空间了。 从报错信息可以很直观的看出：CA_5531DATA表空间中的表无法扩展， 原因一般为：数据文件空间不足且未设置autoextend on属性(自动扩展)或者用户磁盘限
--oracle 9ir2 CREATE DATABASE testdb USER SYS IDENTIFIED BY oracle USER SYSTEM IDENTIFIED BY oracle LOGFILE GROUP 1 ('/u01/app/oracle/oradata/testdb/redo01.log') SIZE 100M, GROUP 2 ('/u01/app/oracle/oradata/testdb/redo02.log') SIZE 100
一、系统表空间扩容方法 方法1：在innodb_data_file_path参数后面加上autoextend参数 innodb_data_file_path=ibdata1:12M:autoextend 方法2：在innodb_data_file_path参数后面加上一个新的数据文件 innodb_data_file_path = /ibdata/ibdata1:988M;/disk2/ibdata2:50M:autoextend 二
the size limit of individual files is determined by the operating system. File size can be more than 4GB on operating systems that support large files. Use of raw disk partitions for global temporary tablespace data files is not supported. 说明：临时表空间的临时
