ORACLE RAC19C到单实例ADG DUPLICATE ORA-01017 错误的解决办法

Posted 2022-12-10 久违的太阳

准备搭建一个19C RAC到单实例的ADG.在duplicate的时候报错ORA-01017用户密码错误

   backup as copy reuse

这个问题以前是很常见的,一般就是密码文件不对,这里仔细检查了发现都是对的.

然后我们尝试使用orapwd修改密码,然后拷贝密码文件,使用sqlplus在primary端和standby端分别连接对方,发现在standby 使用新的密码连接RAC端报错密码错误.这里我们可以得出,使用orapwd修改后的密码在RAC并没有生效,这是为什么呢?

原来到了19c,RAC的密码文件是保存在ASM中,我们可以使用下面的sql语句查看密码文件:

SQL> select * from v$passwordfile_info;

FILE_NAME
--------------------------------------------------------------------------------
FORMAT IS_AS     CON_ID
------ ----- ----------
+DATA/RAC19C/PASSWORD/pwdrac19c.256.1047615941

那么我们怎么解决呢.大概步骤如下:

1.在$ORACLE_HOME/dbs下生成和以前版本一样的密码文件,但是注意文件名和以前不一样,以前版本叫orapwSID,现在直接叫pwdSID了,这里指定了磁盘组:

orapwd file=pwdrac19c asm=data password=Dsg_1234

2.将密码文件拷贝到磁盘组中:

ASMCMD> pwcopy /u01/app/oracle/product/19.3.0.0/db_1/dbs/pwdrac19c .
copying /u01/app/oracle/product/19.3.0.0/db_1/dbs/pwdrac19c -> +DATA/rac19c/password/pwdrac19c

3.修改数据中的密码文件名称

查看当前的密码文件:

[grid@rac19c1 ~]$ srvctl config database -d rac19c -a
Database unique name: rac19c
Database name: rac19c
Oracle home: /u01/app/oracle/product/19.3.0.0/db_1
Oracle user: oracle
Spfile: +DATA/RAC19C/PARAMETERFILE/spfile.272.1047617445
Password file: +DATA/RAC19C/PASSWORD/pwdrac19c.256.1047615941
Domain: 
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server pools: 
Disk Groups: DATA
Mount point paths: 
Services: 
Type: RAC
Start concurrency: 
Stop concurrency: 
Database is enabled
Database is individually enabled on nodes: 
Database is individually disabled on nodes: 
OSDBA group: dba
OSOPER group: oper
Database instances: rac19c1,rac19c2
Configured nodes: rac19c1,rac19c2
CSS critical: no
CPU count: 0
Memory target: 0
Maximum memory: 0
Default network number for database services: 
Database is administrator managed

可以看到Password file为+DATA/RAC19C/PASSWORD/pwdrac19c.256.1047615941

如何修改密码文件呢,使用srvctl modify,查看一下帮助:

[grid@rac19c1 ~]$ srvctl modify database -d rac19c -h

Modifies the configuration for the database.

Usage: srvctl modify database -db <db_unique_name> [-dbname <db_name>] [-instance <instance_name>] [-oraclehome <oracle_home>] [-user <oracle_user>] [-server "<server_list>"] [-timeout <timeout>] [-domain <domain>] [-spfile <spfile>] [-pwfile <password_file_path>] [-role PRIMARY | PHYSICAL_STANDBY | LOGICAL_STANDBY | SNAPSHOT_STANDBY] [-startoption <start_options>] [-stopoption <stop_options>] [-startconcurrency <start_concurrency>] [-stopconcurrency <stop_concurrency>][-policy AUTOMATIC | MANUAL | NORESTART | USERONLY] [-serverpool "<serverpool_list>" [-node <node_name>]] [-pqpool <pq_server_pools>] [-diskgroup "<diskgroup_list>"|-nodiskgroup] [-acfspath "<acfs_path_list>"] [-css_critical YES | NO] [-cpucount <cpu_count> [-overridepools <overridepool_list>]] [-memorytarget <memory_target>] [-maxmemory <max_memory>] [-defaultnetnum <network_number>] [-disabledreason DECOMMISSIONED] [-force] [-eval] [-verbose]

根据帮助说明,使用-pwdfile选项修改密码文件:

[oracle@rac19c1 ~]$ srvctl modify database -d rac19c -pwfile +DATA/RAC19C/PASSWORD/pwdrac19c

修改完成之后,再在standby端使用sqlplus登录验证:

[oracle@ora19c2 dbs]$ sqlplus sys/Dsg_1234@dsgds as sysdba
