I tried to log into the Oracle database. However it displays an error:
An error was encountered performing the requested operation:
ORA-01033: ORACLE initialization or shutdown in progress 01033. 00000 - "ORACLE initialization or shutdown in progress" *Cause: An attempt was made to log on while Oracle is being started up or shutdown. *Action: Wait a few minutes. Then retry the operation. Vendor code 1033
So I tried to fix it flowing the instruction on these websites: https://www.oracletutorial.com/tips/oracle-initialization-or-shutdown-in-progress/ How to install Oracle Instant Client on a Mac?
However, when I tried to log into it, it always appears ''' TNS:net service name is incorrectly specified error. '''
Just wondering which username and password should I use to log in successfully?
The errors are shown below. Could anybody pls help me with that? enter image description here
