Symptoms

Creating the ASMSNMP user on 11.2 ASM RAC reports the next error:

SQL> create user asmsnmp identified by test01;
create user asmsnmp identified by test01
*
ERROR at line 1:
ORA-15306: ASM password file update failed on at least one node

Cause

The ORA-15306 error demonstrates that the ASM password file is missing in one or several node(s) or it is corrupt.

Solution

1) Remove all the ASM password files from each node:

rm Grid Oracle Home/dbs/orapw+ASM1
rm Grid Oracle Home/dbs/orapw+ASM2
.
.
rm Grid Oracle Home/dbs/orapw+ASM<..n>

2) Create ASM password file manually on the first node as the OS user which owns the Grid Infrastructure:

$> orapwd file='orapw+ASM1' entries=5 password=

3) Copy the password file to all nodes with the correct ASM instance name:

scp orapw+ASM1 to remote node : Grid Oracle Home/dbs/orapw+ASM2
scp orapw+ASM1 to remote node : Grid Oracle Home/dbs/orapw+ASM3
.
.
scp orapw+ASM1 to remote node : Grid Oracle Home/dbs/orapw+ASM<..n>

4) Add the ASMSNMP user in ASM instance, and grant sysdba privilege to it:

SQL> create user asmsnmp identified by ;

SQL> grant sysdba to asmsnmp;

5) Verify the ASMSNMP user was created:

SQL> select * from v$pwfile_users;

USERNAME SYSDB SYSOP SYSAS
------------------------------ ----- ----- -----
SYS TRUE TRUE TRUE
ASMSNMP TRUE FALSE FALSE
