Oracle冷备迁移过程和在线日志损坏处理

过程：

alter system switch logfile;

alter database backup controlfile to trace;

shutdown immediate;

拷贝相关文件到移动硬盘，参数口令控制数据和日志文件，监听文件不拷贝

cd /oracle/app/ora11g2/product/11.2.0/dbhome_1/dbs

cp /mnt/jimmydb/dbs/initjimmydb.ora initjimmydb.ora

cp /mnt/jimmydb/dbs/orapwjimmydb orapwjimmydb

cp /mnt/jimmydb/dbs/spfilejimmydb.ora spfilejimmydb.ora

cd $ORACLE_BASE/oradata

cp -r /mnt/jimmydb/oradata/jimmydb jimmydb

配jimmdb的监听

startup mount

ORA-09925: Unable to create audit trail file su - ora11g2 cd $ORACLE_BASE cd diag cd /rdbms/jimmydb/jimmydb/trace

查看alert文件 more altert* 找到原因：Could not open audit file: /oracle/app/ora11g2/admin/jimmydb/adump/jimmydb_ora_4064_2.aud cd /oracle/app/ora11g2/admin/

mkdir jimmydb

cd jimmydb

mkdir adump

mkdir dpdump

mkdir pfile

cd /oracle/app/ora11g2/diag/rdbms/

mkdir jimmydb

复制相关文件：

cd /oracle/app/ora11g2/admin/

cp -r /mnt/jimmydb/admin/jimmydb jimmydb

cd /oracle/app/ora11g2/diag/rdbms/

cp -r /mnt/jimmydb/rdbms/jimmydb  jimmydb

alter databae open--出现在线日志损坏提醒，可能与移动硬盘拷贝有关

select group#,ARCHIVED,status from v$log;

alter database clear unarchived logfile group 1

alter database open;

alter system switch logfile;

select group#,ARCHIVED,status from v$log;
