asm遠端連線可能會遇到以下報錯：

ORA-12505 TNS:listener could not resolve SID given in connect descriptorORA-12541: TNS:no listenerORA-15000: command disallowed by current instance typeORA-12528: TNS:listener: all appropriate instances are blocking new connectionsORA-1031:   insufficient privileges

asm遠端連線配置如下:
參數配置：

remote_login_passwordfile = exclusive ... for stand alone ASM setupsremote_login_passwordfile = shared ... for ASM setups that also use Real Application Cluster (RAC)

節點1：

[[email protected] admin]$ cat listener.ora SID_LIST_LISTENER_prodb1 =  (SID_LIST =    (SID_DESC =      (SID_NAME = PLSExtProc)      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)      (PROGRAM = extproc)     (SID_DESC =       (SID_NAME = +ASM1)         (GLOBAL_DBNAME  = +ASM)         (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)    )  )LISTENER_prodb1 =  (DESCRIPTION_LIST =    (DESCRIPTION =      (ADDRESS = (PROTOCOL = TCP)(HOST = prodb1-vip)(PORT = 1521)(IP = FIRST))      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.10.101)(PORT = 1521)(IP = FIRST))    )  )

節點2：

[[email protected] admin]$ cat listener.ora SID_LIST_LISTENER_prodb2 =  (SID_LIST =    (SID_DESC =      (SID_NAME = PLSExtProc)      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)      (PROGRAM = extproc)     (SID_DESC =       (SID_NAME = +ASM2)         (GLOBAL_DBNAME  = +ASM)         (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)    )  )LISTENER_prodb2 =  (DESCRIPTION_LIST =    (DESCRIPTION =      (ADDRESS = (PROTOCOL = TCP)(HOST = prodb2-vip)(PORT = 1521)(IP = FIRST))      (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.10.102)(PORT = 1521)(IP = FIRST))    )  )

用戶端tnsname.ora:

ASM1 =     (DESCRIPTION =       (ADDRESS_LIST =         (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.10.101)(PORT = 1521))       )       (CONNECT_DATA =         (SERVICE_NAME = +ASM)      (UR=A)     )     )  ASM2 =     (DESCRIPTION =       (ADDRESS_LIST =         (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.10.102)(PORT = 1521))       )       (CONNECT_DATA =         (SERVICE_NAME = +ASM)      (UR=A)     )     )ASM =     (DESCRIPTION =       (ADDRESS_LIST =         (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.10.102)(PORT = 1521))         (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.10.101)(PORT = 1521))     )       (CONNECT_DATA =         (SERVICE_NAME = +ASM)      (UR=A)     )     )

關鍵區段為 (UR=A)，如果不配置該選項，則串連的時候報：

$ sqlplus sys/[email protected] as sysdbaSQL*Plus: Release 10.2.0.5.0 - Production on чǚ? 7? 5 21:44:30 2018Copyright (c) 1982, 2010, Oracle.  All Rights Reserved.ERROR:ORA-12528: TNS:listener: all appropriate instances are blocking new connections

UR=A選項通常用來串連使用nomount，mount或restricted模式啟動資料庫。

資料庫啟動到nomount，監聽狀態為BLOCKED；
資料庫啟動到mount，監聽狀態為READY；
資料庫啟動到restrict，監聽狀態為RESTRICT;
靜態註冊的asm為BLOCKED
