1、 删除旧的全备
$rman rcvcat rman_hainan/rman_hainan@rman target /
Recovery Manager: Release 8.1.6.0.0 - Production
RMAN-06005: connected to target database: TEST (DBID=1692992254)
RMAN-06008: connected to recovery catalog database
RMAN> list backupset;
RMAN-03022: compiling command: list
List of Backup Sets
Key Recid Stamp LV Set Stamp Set Count Completion Time
------- ---------- ---------- -- ---------- ---------- ----------------------
38 145 399987408 0 399987406 153 11-JUN-00
根据key来删除旧的备份。
RMAN> allocate channel for maintenance type disk;
RMAN> change backupset 169 delete; ----------THIS IS THE COMMAND TO REMOVE THE ENTRY & OS FILE
做完后可以看到list backupset和操作系统的文件都没有了。
2、 恢复
（1） 将数据库启动到nomount状态：
$svrmgrl

With the Partitioning option
JServer Release 8.1.6.0.0 - Production
SVRMGR> connect internal

SVRMGR> startup nomount;
ORACLE instance started.

Database Buffers 16384000 bytes
Redo Buffers 4112384 bytes
SVRMGR> exit
Server Manager complete.
（2） 恢复控制文件：
$rman rcvcat rman_hainan/rman_hainan@rman target /
Recovery Manager: Release 8.1.6.0.0 - Production
RMAN-06006: connected to target database: test (not mounted)
RMAN-06008: connected to recovery catalog database
RMAN> run {
2> allocate channel d1 type disk;
3> restore controlfile;
4> release channel d1;
5> }
（3） 恢复数据文件
RMAN> run {
2> allocate channel d1 type disk;
3> sql "alter database mount";
4> restore datafile 1;
5> restore datafile 2;
6> restore datafile 3;
7> restore datafile 4;
8> release channel d1;
9> }
（4） 恢复日志文件
RMAN> run {
2> set archivelog destination to '/export/home/oracle/admin/test/arch';
3> allocate channel d1 type disk;
4> restore archivelog all;
5> release channel d1;
6> }
会把所有的日志文件恢复。
（5） 根据日志做recover
$svrmgrl
