How to install Oracle Database 23ai (23c) Express Edition + SQL Developer on your computer for FREE.

[@Paulo-dc6fk]

hi, thank you for the video, very useful, I wish I had watched this beforehand, I ended up fixing the files using the command prompt, your way is much easier. Question tho, after I install the backend, is the database online all the time? Or only when I open the SQL developer and connect to it, if yes, how do I take it offline, I don't want it running on my PC all of the time.

Hi Paulo. Thank you for your question. The database is probably running all the time. You can control it in Services. I'll make a video about how to switch it on/off. Phillip

Thank you so much, but when I test the program told me that there is no listener at localhost port 1521

I followed each step carefully, but unfortunately, the second installation dialog box did not appear, and I'm having trouble completing the installation

Hi Scroll with Ahmed. Maybe try running it as an administrator. Phillip

Hello, can you also provide any free resources to persue the career of DBA? You can also recommend any book if you want. I am trying to switch my carrer as DBA, but I am confused about quality resources.

Hi Pinak. I'm afraid most of the good resources are not free. Phillip
