oracle 10g 远程连接asm

asm远程连接可能会遇到以下报错：

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远程连接配置如下:
参数配置：

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

节点1：

[oracle@prodb1 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))    )  )

节点2：

[oracle@prodb2 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))    )  )

客户端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)     )     )

关键部分为 (UR=A)，如果不配置该选项，则连接的时候报：

$ sqlplus sys/admin@asm1 as sysdbaSQL*Plus: Release 10.2.0.5.0 - Production on чǚ̄ 7Ղ 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选项通常用来连接使用nomount，mount或restricted模式启动数据库。

数据库启动到nomount，监听状态为BLOCKED；
数据库启动到mount，监听状态为READY；
数据库启动到restrict，监听状态为RESTRICT;
静态注册的asm为BLOCKED
