dblogin userid ogg ERROR: Unable to connect to database using user ogg

测试环境，初步配置ogg，添加ogg用户连接数据库，提示无权限报错。

1.0 报错信息

GGSCI (enmo) > dblogin userid ogg,password ogg
ERROR: Unable to connect to database using user ogg. Please check privileges.
ORA-: ORACLE not available
ORA-: shared memory realm does not exist
Linux-x86_64 Error: : No such file or directory.

2.0 数据库用户登录，权限排查

SQL> create user test001 identified by test001;   

User created.

SQL>
SQL> grant dba to test001;

Grant succeeded.

从报错字面理解报错信息： 无法连接数据库Ogg用户，请检查权限，数据库没有问题，Ogg是否存在问题

[ogg@enmo ogg]$ sqlplus / as sysdba
