[Linux] After connecting to DB with teraterm and typing Sqlplus command, until logging in to DB (oracle)

No response from SQL Developer

Both SELECT and UPDATE are frozen and cannot be updated. I will try to contact the DB directly.

Teraterm IP with DB (XX.XX.XX.XX) Server user Server password port matches server settings

After login

Enter sqlplus enter DB user DB password Enter in order

I put it in! I will try to type SQL. To be continue ...

Problem: Why is the character garbled after inputting sqlplus?

Both Teraterm settings were UTF-8
