Error handling of PLSQL initial login to Oracle

Oracle client and PLSQL are installed on Server1, but after logging in, database and connect as are not displayed

After manually entering the correct user name and database, an error is reported as follows

Therefore, cancel the login and directly enter the PLSQL interface tools connection to check Oracle home and OCI library. It is found that the path of OCI library is wrong

Client2 is the wrong address, and client32 is on the machine

So it was changed to client32

After applying the changes, close the PLSQL interface and restart it. You will see that PLSQL automatically reads all TNS information

Log in with user password OK
