1. 登录操作说明
ORA数据库:
set ORACLE_SID=ora
sqlplus / as sysdba
切换数据库:
set ORACLE_SID=pi
sqlplus / as sysdba
2. 本地登录步骤
通过命令行运行窗口:
C:\Users\Administrator>
设置环境变量
C:\Users\Administrator>set ORACLE_SID=“指定数据库SID”
sqlplus / as sysdba
登陆数据库
C:\Users\Administrator>sqlplus / as sysdba
3. 查看当前数据库:
show parameter name;
4. 取消密码限制:
alter profile default 1imit password_life_time unlimited;
5. 查看是否修改成功
select resource_name,limit from dba_profiles where profile'DEFAULT' and resource_name’=PASSWORD_LIFE_TINE';
6. 表空间扩容、创建表空间
ORA:
查看表空间数据文件及大小:
select tablespace_name,file_id,file_name,bytes/1024/1024 from dba_data_files;
对现有表空间扩容:
alter database datafile 'z:\ORADATA\ORA\UNDOTBS1.DBF' resize 2048m;
alter database datafile 'z:\ORADATA\ORA\SYSTEMO1. DBF' resize 4096m;
alter database datafile 'z:\ORADATA\ORA\SYSAUX01.DBF’ resize 2048m;
查看临时表空间
select tablespace_name,file_id,file_name,bytes/1024/1024 from dba_temp_files;
对现有临时表空间扩容:
alter database tempfile 'z:\ORADATA\ORA\TEMP01.DBF' resize 2048m;
创建表空间:(语句中size和maxsize 根据要求设置,autoextend on代表自动扩展,如果不用自动扩展,可以不要autoextend on和maxsize)
create tablespace newapp datafile 'z:\ORADATA\ORA\NEWAPPO.DBF size 2g autoextend on maxsize 20g;
create tablespace newapp_index datafil 'z:\ORADATA\ORA\NEVAPP_INDEXO.DBF size 1g autoextend on maxsize 20g;
create tablespace angel datatile 'z:\ORADATA\ORA\ANGELO01.DBF size 1g autoextend on maxsize 20g;
创建临时表空间
create temporary tablespace newapp_temp tempfile 'Z:\ORADATA\ORAAPP\NEWAPP_TEMP01.DBF size 1g autoextend on maxsize 20g;
PI:
系统表空间扩容:
alter database datafile 'z:\PI\SYSTEM01.DBF' RESIZE 4G;
alter database datafile 'z:\PI\SYSAUX01.DBF' RESIZE 2G;
alter database datafile 'z:\PI\UNDOTBS01.DBF' RESIZE 2G;
alter database datafile 'z:\PI\TEMP01.DBF' RESIZE 2G;
创建表空间:
create temporary tablespace pi_local_temp tempfile 'z:\PI\pi_1ocal_temp01.DBF’ size 5g autoextend on maxsize 10g;
create bigfile tablespace pi_local_dat_datafile 'z\PI\PI_LOCAL_DATA01.DBF' size 10g autoextend on; maxsize 40G;
create bigfile tablespace pi_local_IDX datafile 'z:\PI\PI_LOCAL_IDX01.DBF' size 5G autoextend on; maxsize 10G;
create bigfile tablespace pi_local_HISTORY_DAT datafile 'z\PI\PI_LOCAL_HISTORY DAT01.DBF' size 10g autoextend on; maxsize 30G;
create bigtile tablespace pi_local_HISTORY_IDX datafile 'z\PI\PI_LOCAL_HISTORY_IDX01.DBF' size 5G autoextend on; maxsize 10G;
