Experience of connecting SQL plus to Oracle on the server

Today, when I use sqlplus to connect to Oracle on the server, I cannot connect to it. The database name on the server is cebdsp, and tnsnames. ora is configured
 
Cebdsp =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.1.101) (PORT = 1521 ))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cebdsp)
)
)
View the tnsping cebdsp in the command line.
 
C: \ Users \ zyxuc> tnsping cebdsp

Used parameter files:
D: \ oracle \ product \ 10.2.0 \ db_1 \ network \ admin \ sqlnet. ora
 
TNS-03505: unable to resolve name
The reason is that there is a space in front of the Coordination cebdsp. After deleting the space, run: tnsping cebdsp to get:
 
C: \ Users \ zyxuc> tnsping cebdsp

)))
OK (30 ms)
Run sqlplus cebdsp/cebdsp @ cebdsp to test whether the database can be connected to the cebdsp database:
 
C: \ Users \ zyxuc> sqlplus cebdsp/cebdsp @ cebdsp
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE does not work
 
Finally, permission issues were discovered. I used a non-Administrator user and did not have the permission. Just change it to the Administrator user.
