[oracle@rac7 dbs]$

There was no password file so getting invalid username/password

=====================================================================

Part 2 :- Password file is created in RAC environment from rac3 node and stored in +DATA diskgroup

[oracle@rac3 ~]$

[oracle@rac3 ~]$ orapwd dbuniquename=orcl file=+DATA/orapworcl format=12 password=welcome#123 force=y entries=10

[oracle@rac3 ~]$

[oracle@rac3 ~]$

Part 3:-

Copying password file from +DATA diskgroup to /tmp location 

[grid@rac3 ~]$ asmcmd

ASMCMD> ls

ARCH/

CRS/

DATA/

ASMCMD> cd D*

ASMCMD> ls -lrt

WARNING:option 'r' is deprecated for 'ls'

please use 'reverse'

ASMCMD>

ASMCMD> pwd

+DATA

ASMCMD> pwcopy orapworcl /tmp

copying +DATA/orapworcl -> /tmp/orapworcl

Part 4:- 

Changing the ownership of password file

 

[root@rac3 tmp]#

[root@rac3 tmp]# chown oracle:oinstall orapworcl

[root@rac3 tmp]#

Part 5:- 

copying password file rac3 to rac7 server using scp command 

[oracle@rac3 tmp]$ scp orapworcl oracle@192.168.0.107:/u01/app/oracle/product/12.2.0.1/db_1/dbs/orapworcl_dg

oracle@192.168.0.107's password:

orapworcl                                    100% 2048     2.3MB/s   00:00

[oracle@rac3 tmp]$

Part 5:-  

Again connecting to Primary instance and Auxiliary instance but still getting same error

[oracle@rac7 ~]$ rman target sys/welcome#123@ORCL auxiliary sys/welcome#123@ORCL_DG

Part 6:-  

Now check below how password file name changed i.e. from orapwdorcl_dg to orapwORCL_DG

[oracle@rac3 tmp]$

[oracle@rac3 tmp]$ scp orapworcl oracle@192.168.0.107:/u01/app/oracle/product/12.2.0.1/db_1/dbs/orapwORCL_DG

oracle@192.168.0.107's password:

[oracle@rac3 tmp]$

Finally got connection 

[oracle@rac7 ~]$
