standby庫歸檔日志斷檔，故standby庫不能利用恢復歸檔日志和生產庫保持同步，因生產庫有1T多，重拉數據將非常耗時，遂利用RMAN對生產庫進行增量備份，將增量備份集合成到standby庫，利用此方法就跨過了被刪除的歸檔日志。具體方法如下：

1。操作平臺如下：

SQL> select * from v$version;

BANNER

----------------------------------------------------------------

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi

PL/SQL Release 10.2.0.4.0 - Production

CORE 10.2.0.4.0 Production

TNS for IBM/AIX RISC System/6000: Version 10.2.0.4.0 - Productio

NLSRTL Version 10.2.0.4.0 - Production

2。在生產庫新生成一個standby controlfile，將其拷貝到備份庫

SQL> alter database create standby controlfile as '/tmp/cc.ctl';

Database altered.

3。利用新生成過來的控制文件重啟備份庫

4。將備份庫注冊到catalog庫，作為生產庫的0級備份

set pagesize 0

set head off

set linesize 150

spool catalog.lst

select 'catalog datafilecopy '||''''||'/Tbackup/orajfdz/oradata/'||substr(name,instr(name,'/',-1)+1)||''''||' level=0'||' tag='||''''||'mcdbra'||''''||';' from v$datafile;

spool off

exit

5。將其注冊到catalog庫

$ rman target / catalog mcdbra/mcdbra@mcdrb

6。連接至生產庫利用RMAN生成增量備份集

備份過程中注意查看相關等待事件

[SQL> /

7。將生成的增量備份集拷貝到備份庫

8。恢復增量備份集至standby庫

RMAN> run {

set newname for datafile 1 to '/u03/stby/system01.dbf';

set newname for datafile 2 to '/u03/stby/undotbs01.dbf';

set newname for datafile 3 to '/u03/stby/indx01.dbf';

set newname for datafile 4 to '/u03/stby/tools01.dbf';

set newname for datafile 5 to '/u03/stby/undotbs02.dbf';

set newname for datafile 6 to '/u03/stby/users01.dbf';

switch datafile all;

recover database noredo;

}
