Hello again... When trying to create the HR user, I get another error... "invalid username/password; logon denied"... I have checked the spelling "hr" and "hr" as the pw. Suggestions and thank you in advance. Steve
if you get "invalid username/password; logon denied"... "solution is" = step 1 - go to system db and type querry - create user "your connection name" identified by 'your password name'; grant dba to 'your connection name' ; step 2- set host name as ip address and ip address is found in this path C:\app\'your pc name'\product\21c\homes\OraDB21Home1 etwork\admin\listener.ora step 3 - service name = XEPDB1 -(for the 21c ) and for 11g its XE step4 - click test step5- connect
Hello again. Steve here. OK... so... I uninstalled Oracle and REinstalled Oracle 12c successfully with NO errors. I already had SQL Developer installed on my machine. I opened SQL Developer and tried to add as you did in the video, "SYSTEM_ADMIN" for the username: system, and pw: admin, I added the Service Name as: XEPDB1, clicked on Test and got an error stating that the network adapter could not establish a connection. Any help on this would be MUCH appreciated. Thank you... Steve

Hello sir ..i had watched the video again n again ,but my doubt is not cleared whether we have to follow the same steps for creating the core schema (for target tables)like hr schema.I am also watching your IICS videos ,there Is a need of another schema for target tables .pls help sir 🙏
Yes, If you want to load the data in same oracle database then create core schema. If you want to load data to any other data base like SQL server or MySQL then create a connection and load.
