直接修改报ORA-01109: database not open：

测试：
节点2修改密码： [[email protected] ~]$ cd $ORACLE_HOME/dbs [[email protected] dbs]$ orapwd file=orapw+ASM2 password=oracle force=y [[email protected] dbs]$ sqlplus sys/[email protected] as sysdba sql*Plus: Release 10.2.0.5.0 - Production on чǚ? 7? 6 02:43:25 2018 copyright (c) 1982,Data Mining and Real Application Testing options sql> 节点1测试： [[email protected] admin]$ sqlplus sys/[email protected] as sysdba sql*Plus: Release 10.2.0.5.0 - Production on чǚ? 7? 6 02:45:31 2018 copyright (c) 1982,Data Mining and Real Application Testing options sql> show parameter remote_login_passwordfile NAME TYPE VALUE ------------------------------------ ---------------------- ------------------------------ remote_login_passwordfile string EXCLUSIVE
官方建议在修改密码前关闭asm实例，测试中未关闭，远程连接正常。
11g中修改密码相对简单：
single instance：
$ export ORACLE_SID=+ASM $ asmcmd ASMCMD> passwd sys Enter old password (optional): Enter new password: ******
Cluster environment
ASMCMD> orapwusr --modify --password sys Enter password: ASMCMD> exit
