MRP0: Background Media Recovery process shutdown (orcl1)

由于redo中有migration操作,导致备库mrp应用进程失败,解决此类问题最简单的方法,就是把备库重启到mount状态,然后使用rman进行恢复操作,然后再继续open库,启动mrp解决这类问题

由于lgwr进程遭遇ORA-04020,从而使得lgwr进程异常,进而整个数据库crash.

A deadlock among DDL and parse locks is detected.
This deadlock is usually due to user errors in
the design of an application or from issuing a set
of concurrent statements which can cause a deadlock.
This should not be reported to Oracle Support.
The following information may aid in finding
the errors which cause the deadlock:

win平台rman备份和删除dg备库归档日志脚本

总觉得使用windows跑oracle是不靠谱的事情,可以这个世界上总有很多人喜欢做类似这样的事情,对于数据库比较常见的两件事情:rman和删除dg备库归档日志,在linux/unix平台上使用shell实现很简单,可是跑到win里面,就变的烦了,不是因为其麻烦,而是因为用的人少,不知道怎么下手处理该事情,我编写了简单的实现初级功能的win下面rman备份和删除备库归档日志脚本,供大家参考,也更加欢迎朋友提出来更加好的处理方法(win是真心的不懂)
rman备份脚本

--backup_oracle.bat文件
rman target / cmdfile=D:\backup\rman\backup_db.rman 
log=d:/backup/rman/logfile/rmanlog%date:~0,4%%date:~5,2%%date:~8,2%.log

--backup_db.rman文件
CONFIGURE RETENTION POLICY TO REDUNDANCY = 2;
CONFIGURE DEVICE TYPE DISK PARALLELISM 2;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
backup filesperset = 5 as compressed backupset database format 'd:/backup/rman/full_%U.rman';
sql 'alter system archive log current';
backup  filesperset = 50 as compressed backupset archivelog  all format 'd:/backup/rman/arch_%U.rman'  delete input;
DELETE noprompt OBSOLETE;
crosscheck backup;
delete noprompt expired backup;
backup  format 'd:/backup/rman/ctl_%U.rman' current controlfile;
backup spfile format 'd:/backup/rman/spfile_%U.rman' ;
exit;

backup_oracle.bat文件加入到计划任务即可

删除dg备库归档日志(已经应用)

--delete_dg_archivelog.bat
rem 注意修改 部署目录
cd D:\win_xifenfei
d:
rem 注意delete_archive.sql 查询是否有记录

echo delete archivelog staring > delete_archivelog.bak
sqlplus / as sysdba @delete_archive.sql
echo rman target / cmdfile=rman_checkcross.rman>>delete_archivelog.bat 
delete_archivelog.bat >>delete_dg_archivelog_%DATE:~0,4%%DATE:~5,2%%DATE:~8,2%".log
exit

--delete_archive.sql
set lines 150
col name for a150
set pagesize 0 feedback off verify off heading off echo off
spool delete_archivelog.bat
select 'del '||name from v$archived_log where APPLIED='YES' AND NAME IS NOT NULL and DEST_ID=1;
spool off
exit;

--rman_checkcross.rman
crosscheck archivelog all;
delete noprompt expired archivelog all;
exit

delete_dg_archivelog.bat加入到计划任务即可
