duplicate报ORA-01017权限问题

今天在配置DG的过程中，前期环境都已经准备好了，就差最后一步将RAC数据duplicate到standby端，但是蹊跷的事情就在这一步发生了，

环境：

OS:RedHat EnterPrise Linux 5.8 x64

Cluster:Oracle Grid 11.2.0.4

Database:Oracle Database EnterPrise 11.2.0.4

Archive:RAC+DG

今天在配置DG的过程中，前期环境都已经准备好了，就差最后一步将RAC数据duplicate到standby端，但是蹊跷的事情就在这一步发生了，尝试几次都无法将数据duplicate过去，当然我尝试通过拷贝rman备份到对端也无法完成恢复，死活就报ORA-01017错误，，经过几个小时的努力，问题最终也算是得到了比较好的解决。

ORA-01017:invalid username/password; logon denied

问题分析：

1、 从上面告警日志来看，ORA-01017可以很明显看出是由于权限问题导致。

随即，我们开始检查备库的密码文件，$ORACLE_HOME/dbs/orapw{SID}是存在的。

[oracle@standby dbs]$ ll$ORACLE_HOME/dbs/orapw*
-rw-r----- 1 oracle oinstall 1536 May 2617:49 /DBSoft/oracle/product/11.2.4/dbhome_1/dbs/orapwstandby

2、 这个时候我们应该查看的是数据库的alter告警文件:

Errorsin file/DBSoft/oracle/diag/rdbms/standby/standby/trace/standby_asmb_11087.trc (incident=24130):
ORA-00600:internal error code, arguments: [OSDEP_INTERNAL], [], [], [], [], [], [], [],[], [], [], []

从告警文件中我们可以很明显的看出是ASM磁盘有问题，进入进入grid用户下用srvctl命令检查asm状态：

[grid@standby~]$ srvctl status asm
ASM isrunning on standby

SQL>select name,state,free_mb from v$asm_diskgroup;

NAME STATE FREE_MB
--------------------- ----------
DATA001 MOUNTED 121112
ARC001 MOUNTED 122483
BAK001 MOUNTED 122826

结果看来ASM也是没有问题的，那么唯一的出问题的地方可能就是Oracle哪里配置的问题。

3、这个时候我们应该先看看会不会是权限的问题：

[root@standby ~]# id oracle
uid=501(oracle) gid=504(oinstall)groups=504(oinstall) ,505(dba)
[root@standby ~]# id grid
uid=500(grid) gid=504(oinstall) groups=504(oinstall),503(asmadmin),506(asmdba),507(asmoper)
