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

alterdatabaseforcelogging;
selectforce_loggingfromdba_tablespaces;
selectforce_loggingfromv$database;
altertablespacetestforcelogging;
selectlogging,table_name,tablespace_namefromuser_tableswheretable_name='TEST';
altertablespacetestnoforcelogging;
selecttablespace_name,logging,force_loggingfromdba_tablespaces;

##配置主库的归档删除策略

CONfigUREARCHIVELOGDELETIONPOLICYTOAPPLIEDONSTANDBY;

--传过去就删除

CONfigUREARCHIVELOGDELETIONPOLICYTOSHIPPEDTOSTANDBY;

备库删除脚本

vi delete_archive.sh

#!/bin/sh
source/home/oracle/.bash_profile
exportORACLE_SID=standby
TABLE='v$archived_log'
$ORACLE_HOME/bin/sqlplus-silent"/assysdba"<<EOF
setheadingoff;
setpagesize0;
settermoff;
setFeedbackoff;
setlinesize199;
settrimson;
setverifoff;
spool/home/oracle/scripts/del_arch.sh;
select'rm-rf'||namefromv\$archived_logwhereDELETED='NO'andAPPLIED='YES';
spooloff;
exit;
EOF
chmod+x/home/oracle/scripts/del_arch.sh
sh/home/oracle/scripts/del_arch.sh
rmantarget/<<EOF
crosscheckarchivelogall;
deletenopromptexpiredarchivelogall;
exit;
EOF

增加定时任务：crontab -e

01***su-oracle-c/home/oracle/scripts/delete_archive.sh1

备库自启动脚本：

vi /etc/rc.local

su-oracle-c/home/oracle/scripts/start_db.sh
vistart_db.sh
source/home/oracle/.bash_profile
lsnrctlstart
exportORACLE_SID=standby
sqlplus/assysdba<<EOF
startup;

exit
