oracle 10g rman备份与恢复之四
nocatalog rman恢复
dbid用来恢复spfile和controlfile用到
CONFIGURE CONTROLFILE AUTOBACKUP ON;
backup database plus archivelog delete input；
备份补充
RMAN> show all
2> ;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/ora10g/product/10.2.0/db_1/dbs/snapcf_wolf.f'; # default
防止controlfile丢失
CONFIGURE CONTROLFILE AUTOBACKUP ON; 启用后会自动备份controlfile和spfile
先把之前的备份全部删除
delete backupset

下面是我先在系统里面用rm删掉的，os里面删了之后，rman里面还会有信息，必须用crosscheck backupset，做标记，然后在删除。

恢复
1、口令文件恢复
[root@redhat dbs]# pwd
/oracle/ora10g/product/10.2.0/db_1/dbs
[root@redhat dbs]# ls
hc_wolf.dat initdw.ora init.ora lkDUMMY lkWOLF orapwwolf snapcf_wolf.f spfilewolf.ora
[root@redhat dbs]#
假设口令文件丢失
重建口令文件
[oracle@redhat ~]$ cd /oracle/ora10g/product/10.2.0/db_1/dbs
[oracle@redhat dbs]$ orapwd file=orapwwolf password=123456 entries=5
[oracle@redhat dbs]$ ls
hc_wolf.dat initdw.ora init.ora lkDUMMY lkWOLF orapwwolf orapwwolf.bak snapcf_wolf.f spfilewolf.ora
[oracle@redhat dbs]$
[oracle@redhat dbs]$ orapwd
Usage: orapwd file=<fname> password=<password> entries=<users> force=<y/n>
where
file - name of password file (mand),
password - password for SYS (mand),
entries - maximum number of distinct DBA and force - whether to overwrite existing file (opt),
OPERs (opt),
There are no spaces around the equal-to (=) character.
2、spfile丢失（dbid=3778783462）
startup nomount
set dbid dbid_number
restore spfile from autobackup
shutdown immediate
set dbid dbid_number
startup
模拟丢失spfile
SQL> show parameter spfile
NAME T
