热备份和恢复自动产生sql源代码
各变量含义为:
HOT_BACK_DIR: 热备份文件存放目录
SCRIPT_FILE: 此代码所生成的批处理文件路径及文件名称
LOG_FILE: 备份日志文件存放路径及文件名称
INT_PWD: internal用户的口令
以下代码存成sql文件后
可以通过COMMAND :sqlplus internal/@sqcdb @产生备份SQL代码的原文件名 <参数> 来运行。
热备份SQL源代码如下:
define HOT_BACK_DIR = e:\oradb\hotbackups
define SCRIPT_FILE = e:\back\hotbackup.sql
define LOG_FILE= e:\back\hotbackup.log
define INT_PWD =
/* Create Temporary Table with Tablespace Data */
drop table dsc_hot_stage;
create table dsc_hot_stage
(tablespace_name varchar2(30),
file_name varchar2(200)
);
insert into dsc_hot_stage
select rtrim(tablespace_name),rtrim(file_name) from sys.dba_data_files;
/**** Set up the parameters for the spool file */
set feedback off
set heading off
set pagesize 0
set linesize 128
set verify off
set termout oN
set echo off
spool &SCRIPT_FILE
select '/* ',
'This is the hot backup script and has been generated',
' by gen_hotbk.sql',
' ' || to_char(sysdate, 'YYYY-MM-DD HH24:MI:SS') ,

group by tablespace_name,file_name order by 1;
-- Create Script to backup Init.ora files
--select '$copy c:\\admin\sqcdb\pfile\init.ora --&HOT_BACK_DIR\ora'||' /y' from dual;
-- Create Script to backup Net Config files
--select '$copy C:\Oracle\Ora81\NETWORK\ADMIN\*.ora --&HOT_BACK_DIR\ora'||' /y'from dual;
select 'spool &LOG_FILE ' from dual;
select 'prompt ' ,'COMPLETE HOT BACKUP DATABASE SQCDB ON ' ,to_char(sysdate, 'YYYY-MM-DD HH24:MI:SS') from dual;
select 'spool off' from dual;
select 'exit' from dual;
spool off
@&SCRIPT_FILE
$del &SCRIPT_FILE
exit
热恢复SQL源代码如下
define HOT_BACK_DIR = e:\oradb\hotbackups
define SCRIPT_FILE = e:\back\hotrev.bat
define LOG_FILE= e:\back\hotrev.log
define INT_PWD =
/* Create Temporary Table with Tablespace Data */
drop table dsc_hot_stage;
create table dsc_hot_stage
(
tablespace_name varchar2(30),
file_name varchar2(200)
);
insert into dsc_hot_stage
select rtrim(tablespace_name),rtrim(file_name) from sys.dba_data_files;
/**** Set up the parameters for the spool file */
set feedback off
set heading off
set pagesize 0
set linesize 128
set verify off
set termout oN
set echo off
set pages 0 feed off echo off time off
