1.在生产数据库上执行，报RMAN-20004错：
RMAN> list backup of datafile 41;
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of list command at 07/27/2013 18:37:05
RMAN-06004: ORACLE error from recovery catalog database: RMAN-20004: target database name does not match name in recovery catalog
解决方法：
a.在测试数据库上的rman中执行：unregister database
b.在正式库上执行：register database
2.在测试库上执行恢复时，报以下RMAN-20201错：
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of set command at 07/27/2013 17:18:28
RMAN-06004: ORACLE error from recovery catalog database: RMAN-20201: datafile not found in the recovery catalog
RMAN-06010: error while looking up datafile: 42
解决方法：
方法一. resync catalog
方法二.如果同步不成功
RMAN> resync catalog;
full resync skipped, target database not mounted
则查看incarnation
RMAN> list incarnation;
List of Database Incarnations
DB Key Inc Key DB Name DB ID STATUS Reset SCN Reset Time

上面查看到有ristst2测试库的注册信息，影响到无法查询恢复文件。
所以先在测试库中执行unregister database，再在正式库中register database。
然后再list backup of datafile就能找到文件了。
3.从catalog恢复database时报RMAN-06023: no backup or copy of datafile 1 found to restore
解决方法：检查连接catalog的帐号和密码是否与备份脚本中的一致。
4.rman恢复时报ORA-27211错误
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of allocate command on t1 channel at 12/19/2013 11:09:11
ORA-19554: error allocating device, device type: SBT_TAPE, device name:
ORA-27211: Failed to load Media Management Library
查看libobk.so是否安装和建立：
-bash-3.00$ cd $ORACLE_HOME/lib
-bash-3.00$ ls -ltr|grep libobk.so
lrwxrwxrwx 1 ristest2 dba 21 Dec 19 16:33 libobk.so -> /usr/lib/libnsrora.so
若没有，建立link文件：
solaris:
ln -s /usr/lib/libnsrora.so libobk.so
aix:
ln -s /usr/lib/libnsrora.a libobk.a
测试是否正常：
-bash-3.00$sbttest libobk.so
he sbt function pointers are loaded from oracle.static library.
libobk.so could not be loaded. Check that it is installed
解决方法：
a.上面检查libobk.so表示有存在和安装
b.将以下变量加入.profile中
-bash-3.00$ echo $LIBPATH
/apps/ristest2/product/10gr2/lib:/apps/ristest2/product/10gr2/network/lib:/lib:/usr/lib:/usr/local/lib
-bash-3.00$ echo $LD_LIBRARY_PATH
/apps/ristest2/product/10gr2/lib:/apps/ristest2/product/10gr2/network/lib:/usr/lib:/usr/local/lib
测试正常。
-bash-3.00$ sbttest libobk.so
The sbt function pointers are loaded from libobk.so library.

5.在测试环境中恢复rac数据库，报ORA-19511错：
channel t1: starting datafile backup set restore
channel t1: specifying datafile(s) to restore from backup set

解决方法：
在测试环境主机的/etc/hosts中加入正式rac两节点的主机名和IP对应关系。
6.rman恢复时报RMAN-06004错误,如下：

RMAN-06004: ORACLE error from recovery catalog database: RMAN-20001: target database not found in recovery catalog
解决方法：
set dbid=xxxxx;
再执行恢复脚本。
7.rman恢复时报ORA-27191错误,如下：
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 01/08/2015 21:57:53
ORA-27191: sbtinfo2 returned error
Additional information: 3480
解决方法：
检查host记录，发现主机名与localhost写在了同一行
-bash-4.1$ cat /etc/hosts
::1 msuu332 localhost
127.0.0.1 msuu332 msuu332.midea.com.cn localhost loghost
#Backup Level 1
10.16.16.66 mhpl800
10.16.16.67 mhpl801
10.16.16.68 mhpl802
要另起一行写，改成如下：
::1 localhost
127.0.0.1 localhost loghost
10.16.18.161 msuu332 msuu332.midea.com.cn
8.正式库上list操作，报RMAN-20001错误,如下：
RMAN> list backup of datafile 1;
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of list command at 01/15/2015 09:30:53
RMAN-06004: ORACLE error from recovery catalog database: RMAN-20001: target database not found in recovery catalog
解决方法：
在库上执行：register database
9.测试库上rman恢复时报0509-022错误，如下：
0509-022 Cannot load module /usr/lib/nsr/lib64/libDDBoost.so. 0509-026 System error:A file or directory in the path name does not exist.
解决方法：
lrwxrwxrwx 1 1201 dba 20 Jan 04 22:11 libobk.a -> /usr/lib/libnsrora.a
link文件的onwer显示异常，在$ORACLE_HOME/lib下rm libobk.a，再ln -s /usr/lib/libnsrora.a libobk.a。
