RMAN-00554 RMAN-04005 ORA-12528
RMAN在使用recover catalog的情況下在nomount狀態串連執行個體出現以下錯誤資訊:
RMAN-00554: initialization of internal recovery manager package failed
RMAN-04005: error from target database:
ORA-12528: TNS:listener: all appropriate instances are blocking new connections
下面我來類比一下這種情況
1.將資料庫置於nomount狀態
SQL> startup nomount
Oracle instance started.
Total System Global Area 327155712 bytes
Fixed Size 1273516 bytes
Variable Size 138412372 bytes

2.串連目標資料庫
[oracle@oracle11g ~]$ rman target sys/zzh_2046@test catalog rman/rman@jy

3.檢查監聽狀態
[oracle@oracle11g ~]$ lsnrctl status

The command completed successfully
從上面的資訊可以看到Instance "test",status BLOCKED,對於ora-12528錯誤在MOS有一篇文章描述造成這種問題的原因:
Cause
When an instance is in restricted mode, PMON updates the listener with that information and blocks new connections from being established.
The lsnrctl services output will show the handler is blocked for new connections or lsnrctl status may show the instance is in RESTRICTED mode.
解決方案如下:
The (UR=A) clause for TNS connect strings was created in response to an enhancement request. This clause can be inserted into the "(CONNECT_DATA=" section of a TNS connect string and allow a privileged or administrative user to connect via the listener even when the service handler is blocking connections for non-privileged users.
Here's an example of a connect string configured with (UR=A):
PROD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = myhost.oracle.com)(PORT = 1521)))
(CONNECT_DATA =
(UR=A)
(SERVICE_NAME = prod10ib.oracle.com)
)
)
Please note that the (UR=A) clause is intended to work with a dynamically registered handler so the use of SERVICE_NAME versus SID is required when using dynamic registration (i.e. handler exists in lsnrctl output but is BLOCKED). The use of SID in a TNS connect string may allow a connection if using a static handler in the listener.ora file under SID_DESC.
4.修改tns檔案增加(UR=A)
[oracle@oracle11g admin]$ vi tnsnames.ora
test =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.2)(PORT = 1521))
)
(CONNECT_DATA =
(UR=A)
(SERVICE_NAME = test)
)
)
jy =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.11)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = jy)
)
)
5.再次串連目標資料庫執行恢複
[oracle@oracle11g admin]$ rman target sys/zzh_2046@test catalog rman/rman@jy

出現這個問題的原因是當使用動態註冊監聽時,當執行個體處於限制模式或受阻的情況下PMON將會更新監聽程式來阻新的串連,解決方案其實有兩種:
一是在tns串連描述串中增加(UR=A)子句來讓動態監聽程式使用service_name來進行註冊
二是使用靜態監聽註冊
