You can set ORACLE_BASE manually if it is required. Resetting ORACLE_BASE to its previous value or ORACLE_HOME The Oracle base has been set to /opt/oracle/product/18c/dbhomeXE
Once you have done that you can connect via the SQL prompt. The format for the connect string is: [user]/[password]@//[hostname]:[port]/[DB name] [AS [role]]
sqlplus sys/passwd//localhost:1521/XE as sysdba
