Hi folks I am on Windows 10 and trying to install Oracle XE 21c I downloaded the install here: https://www.oracle.com/ca-en/database/technologies/xe-downloads.html I went through the installation with all the defaults and no issues up until this step I got hit with the following error {IDS_OracleConfigDlg_DatabaseConfigFailedMsg} An error occured while configuring Oracle XE database. Check the logs at C:\app\user\product\21c\cfgtoollogs\dbca and try again I clicked on "Retry" but got hit with the same error. Then I went to "Abort" and the installation appeared to complete. I did a quick tnsping and see the following I thought great - Ok maybe its just an error but things are up and running. When I try to connect via the newly installed SQL Plus I hit the following error Weird ok, I then try to connect via SQL developer and see the following error Status : Failure -Test failed: Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor (CONNECTION_ID=xtAG2YGQTYCEiT634/dAvg==) Alright well this sucks, I went to the previously suggested logs when I initially hit the error here: C:\app\user\product\21c\cfgtoollogs\dbca And I then see the following 4 log files The contents of the log file are pretty big so I wont post it here But does anyone know what could be wrong? I was really hoping to install Oracle XE to re-immerse myself in the Oracle database ecosystem for an upcoming project. Any advice much appreciated
