dataguard oracle 归档管理脚本

管理部分
如果没有启用database force logging,则备库对/*+ append */操作，nologging操作，会报坏块；
建议表空间force logging或者database force logging;
--force logging /nologging 测试

alter database force logging;
select force_logging from dba_tablespaces;
select force_logging from v$database;
alter tablespace test force logging;
select  logging,table_name,tablespace_name from user_tables where table_name ='TEST';
alter tablespace test no force logging;
select tablespace_name,logging,force_logging from dba_tablespaces;

##配置主库的归档删除策略

CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

--传过去就删除

CONFIGURE ARCHIVELOG DELETION POLICY TO SHIPPED TO STANDBY;

备库删除脚本
vi delete_archive.sh

#!/bin/sh
source /home/oracle/.bash_profile
export ORACLE_SID=standby
TABLE='v$archived_log'
$ORACLE_HOME/bin/sqlplus -silent "/ as sysdba" <<EOF
set heading off;
set pagesize 0;
set term off;
set feedback off;
set linesize 199;
set trims  on ;
set verif off;
spool /home/oracle/scripts/del_arch.sh;
select 'rm -rf '||name from v\$archived_log  where DELETED='NO' and APPLIED='YES';
spool off;
exit;
EOF
chmod +x /home/oracle/scripts/del_arch.sh
sh /home/oracle/scripts/del_arch.sh
rman target / <<EOF
crosscheck archivelog all;
delete noprompt expired archivelog all;
exit;
EOF

增加定时任务：crontab -e

0 1 * * *  su - oracle -c     /home/oracle/scripts/delete_archive.sh 1

备库自启动脚本：
vi /etc/rc.local

su - oracle -c /home/oracle/scripts/start_db.sh
vi start_db.sh
source /home/oracle/.bash_profile
lsnrctl start
export ORACLE_SID=standby
sqlplus / as sysdba <<EOF
startup;
recover managed standby database using current logfile disconnect from session;
exit
