Oracle建立表空间和用户
需求来自要把原数据导入到新的机器的新空间和新用户里面。
1、我们查看一下原来库的建表空间语句。
//注意只导业务表空间即可，有些是系统空间是每台机器，根据情况不同设定的，不用管它。
2、新建表空间的步骤 建物理表空间，建用户，建权限。
系统采样(防止下面的语句跟大家执行的不匹配)
1、oracle版本 11.2.0.4.0
2、系统版本
[oracle@shdb02 /]$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 6.4 (Santiago)
3、内核版本
[oracle@shfpdb02 /]$ uname -r 2.6.32-358.el6.x86_64
一、查看当前的表空间创建语句
//要迁移的oracle表空间信息采集.(集群版)
[oracle@shdb02 /]$ echo $ORACLE_SID
fp2

在新的机器的oracle上执行（单机版）
1、创建表空间
oracle@prd:/home/oracle$export ORACLE_SID=fp
oracle@prd:/home/oracle$echo $ORACLE_SID
fp
oracle@prd:/home/oracle$sqlplus / as sysdba

LOGGING ONLINE PERMANENT BLOCKSIZE 8192 EXTENT MANAGEMENT LOCAL AUTOALLOCATE DEFAULT NOCOMPRESS SEGMENT SPACE MANAGEMENT AUTO;
Tablespace created.
2、创建用户
oracle@prd:/home/oracle$export ORACLE_SID=fp
oracle@prd:/home/oracle$echo $ORACLE_SID

查看库中的信息
1、 查查看用户和默认表空间的关系。 SQL> set pagesize 0 SQL> set line 9999 SQL> select username,default_tablespace from dba_users; SYS SYSTEM SYSTEM SYSTEM SH SH SH2 SH2 OUTN SYSTEM APPQSSYS SYSAUX DBSNP SYSAUX DIP SH ORACLE_OCM SH 9 rows selected. 2、查看表空间的名称及大小 SQL>SELECT t.tablespace_name, round(SUM(bytes / (1024 * 1024)), 0) ts_size FROM dba_tablespaces t, dba_data_files d WHERE t.tablespace_name = d.tablespace_name GROUP BY t.tablespace_name;
SYSAUX 325 UNDOTBS1 200 SYSTEM 350 SH2 100 SH 23648 3、查看表空间物理文件的名称及大小 (红色业务表) SQL>SELECT tablespace_name, file_id, file_name, round(bytes / (1024 * 1024), 0) total_space FROM dba_data_files ORDER BY tablespace_name;
