說明：在DataGuard的搭建中，運行rman恢復的時候報錯ORA-12528的錯誤；
腳本如下：RMAN> connect auxiliary sys/Oracle@SCMPRD02
解決步驟：
1、檢查監(jiān)聽是否啟動，腳本：tnsping SCMPRD02
方法一：配置數(shù)據(jù)庫的監(jiān)聽為靜態(tài)參數(shù)步驟：在ORACLE_HOME/network/admin 下面檢查是否有l(wèi)istener.ora參數(shù)文件，如果沒有的話運行netca創(chuàng)建數(shù)據(jù)庫的監(jiān)聽，配置完成的監(jiān)聽文件如下：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = SCMPRDDB02)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle
方法二：修改tnsnames.ora文件
SCMPRD02 =
(DESCRIPTION =
(ADDRESS =
(PROTOCOL = TCP)(HOST = WELL)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED) (
SERVICE_NAME = SCMPRD02)
(UR = A) //增加該備注//
)
)
總結(jié)：ORA-12528: TNS:listener: all appropriate instances are blocking new connections
因為我們復制數(shù)據(jù)庫只是在nomount下打開，而數(shù)據(jù)庫并沒有mount,在11g下所有的監(jiān)聽都是動態(tài)監(jiān)聽，而只有在數(shù)據(jù)庫mount以后，PMON進程起來以后，才能動態(tài)注冊。所以對輔助數(shù)據(jù)庫沒有辦法注冊，只能被鎖住。所以修改數(shù)據(jù)庫的監(jiān)聽為靜態(tài)監(jiān)聽，或者增加（UR=A)即可解決問題。謝謝閱讀，希望能幫到大家，請繼續(xù)關(guān)注腳本之家，我們會努力分享更多優(yōu)秀的文章。
