google了下，執行如下命令還是沒有生效。
ALTER SYSTEM SET LOG_ARCHIVE_DEST_3=’location=/pddata2/app/oracle/archivelog3’ SCOPE=SPFILE;
1.1，去查看下報錯的這個log_archive_dest_3目錄路徑：
[oracle@localhost network]$ cd $ORACLE_HOME
[oracle@localhost dbhome_1]$ cd dbs
[oracle@localhost dbs]$ strings spfile*.ora |grep dest_3;
*.log_archive_dest_3='LOCATION=/data/oracle/oradgdata/standby_archive VALID_FOR=(STANDBY_LOGFILES,STA
*.log_archive_dest_3='LOCATION=/data/oracle/oradgdata/standby_archive VALID_FOR=(STANDBY_LOGFILES,STANDBY_ROLE) DB_UNIQUE_NAME=pddgunq'
[oracle@localhost dbs]$
1.2 解決方法換個路徑然後新建/data/oracle/oradgdata/standby_archive文件夾目錄，oracle可以啟動起來了，但是我想講/data目錄切換成/pddata2/因為data目錄空間太小了，那麼這個時候可以有許多種辦法的。而且也可以借此機會清理一下磁盤空間。
看到dest_3的為/data/oracle/oradgdata/standby_archive
但是/data已經不存在了，所以直接vim改成/pddata2/app/oracle/archivelog3
1.3，將備份copy到備庫上面去，同目錄
backup current controlfile for standby format '/pddata2/oracle/backup/data/ctlfile.bak.20150610';

2，在備庫上恢復控制文件兩種方法：
2.1 直接生成
[oracle@localhost data]$ su - oracle
SQL> backup current controlfile for standby format '/pddata2/oracle/backup/data/ctlfile.bak.20150610';
[oracle@localhost data]$ cp ctlfile.bak.20150610_2 /home/oradata/powerdes/control01.ctl
[oracle@localhost data]$ cp ctlfile.bak.20150610_2 /oracle/app/oracle/flash_recovery_area/powerdes/control02.ctl
2.2 從備份中恢復控制文件，啟動為nomount狀態下：
RMAN> restore controlfile from "/pddata2/oracle/backup/data/ctl_auto/c-3391761643-20150610-01";
Starting restore at 10-JUN-15

output file name=/home/oradata/powerdes/control01.ctl
output file name=/oracle/app/oracle/flash_recovery_area/powerdes/control02.ctl

RMAN>
2.3 將歸檔日志copy過去到standby上[oracle@localhost archivelog]$ scp * [email protected]:/oracle/app/oracle/flash_recovery_area/archivelog/
3，在primary主庫上操作：run {
allocate auxiliary channel c1 device type disk;
allocate auxiliary channel c2 device type disk;
duplicate target database for standby nofilenamecheck dorecover;
release channel c1;
release channel c2;
}
[oracle@localhost data]$ rlwrap rman target / auxiliary sys/xxxx@STU
rlwrap: warning: your $TERM is 'xterm' but rlwrap couldn't find it in the terminfo database. Expect some problems.

去找下缺失的dbf文件是否存在，原來文件一直存在
[root@localhost ~]# find / -name *33499*.dbf
/oracle/app/oracle/flash_recovery_area/archivelog/1_33499_821708334.dbf
[root@localhost ~]# find / -name *33512*.dbf
/oracle/app/oracle/flash_recovery_area/archivelog/1_33512_821708334.dbf
[root@localhost ~]#
將這些將歸檔日志copy到從庫
[root@localhost archivelog]# scp 335.dbf [email protected]:/oracle/app/oracle/flash_recovery_area/archivelog/
[root@localhost archivelog]# chown -R oracle.dba /oracle/app/oracle/flash_recovery_area/archivelog/*
4，上一步中，如果為MOUNTED，則可以開始啟動備庫的REDO應用，去從庫執行：先去主庫執行：
ALTER system SET log_archive_dest_state_2 = ‘defer’;
alter database recover managed standby database disconnect from session;
備庫執行：
SQL> alter database recover managed standby database disconnect from session;
Database altered.
SQL>
SQL> alter database recover managed standby database cancel;
Database altered.
SQL>
發現歸檔日志無法傳輸過來，而且缺失33499到33512的歸檔日志。想了想以前可以基於scn做過增量恢復standby的，可以試試。
5，利用SCN增量備份來恢復standby庫先備份：
backup device type disk incremental from scn 11195658616 database format ‘/home/oracle/db_incre%U.bbk’;
ALTER system SETlog_archive_dest_state_2 = ‘defer’
然後創建恢復的控制文件：
ALTER DATABASE CREATE standby controlfile AS ‘/home/oracle/standby1.ctl’;
/pddata2/oracle/backup/data
細節再使用基於scn增量備份的恢復程序：
