【ASM】ASMSNMP用户已存在

ASMASMSNMP用户已存在

During Oracle Grid Infrastructure for a cluster installation, the ASMSNMP account is created and its status is set to OPEN. It is granted the SYSDBA for ASM privilege. Oracle Enterprise Manager requires access to the ASMSNMP account to monitor Oracle ASM instances and retrieve data from ASM-related data dictionary views.

根据官方文档资料,可见ASMSNMP用户是在集群安装过程中,创建GRID的时候创建的用户。该用户为OPEN状态并被赋予了SYSDBA权限。OEM需要该用户来监控ASM实例并从ASM实例相关的数据字典中获取数据。

客户在安装EM的时候,在ASM实例下需要建立ASMSNMP用户:

SQL> create user asmsnmp identified by oracle123;

create user asmsnmp identified by oracle123

                                  *

ERROR at line 1:

ORA-01920: user name 'ASMSNMP' conflicts with another user or role name

 

该错误说明该用户已存在,但客户想通过查询的方式来确认该用户是否真的存在。在ASM实例中查询:

SQL> select * from v$pwfile_users;

 

USERNAME                       SYSDB SYSOP SYSAS SYSBA SYSDG SYSKM     CON_ID

------------------------------ ----- ----- ----- ----- ----- ----- ----------

SYS                            TRUE  TRUE  TRUE  FALSE FALSE FALSE         0

ASMSNMP                        TRUE  FALSE TRUE  FALSE FALSE FALSE         0

asmcmd命令中查看:

ASMCMD> lspwusr

Username sysdba sysoper sysasm

     SYS   TRUE    TRUE   TRUE

ASMSNMP   TRUE   FALSE   TRUE

 

ASMCMD> help lspwusr

        lspwusr

 

        List the users from the local Oracle ASM password file

 

        lspwusr [--suppressheader]

 

        The options for the lspwusr command are described below.

 

        --suppressheader    - Suppresses column headers from the output.

 

        The following is an example of the lspwusr example.

        The example lists the current current users in the local Oracle ASM

        password file.

 

        ASMCMD [+] > lspwusr

        Username sysdba sysoper sysasm

             SYS   TRUE    TRUE   TRUE  

         ASMSNMP   TRUE   FALSE  FALSE
