Greetings, dear visitor of the Oracle DBA site!

This resource collects notes related to the administration of Oracle databases and closely related technologies (Oracle Database, Weblogic, Oracle Golden Gate, etc.).

Notes may contain errors; as they are found and as new knowledge emerges, the content will be corrected.

Unfortunately, I cannot publish all materials, so the site contains examples of a fairly general nature.

If you find an error, write to me, we’ll fix it!

Critical comments? Yes, please, but keep it constructive.

P.S. I moved to development quite a while ago, mainly Java (Oracle ADF / JET framework), but sometimes I still have to do something in SQL and PL/SQL. As a result, I haven’t upgraded my administration skills for a long time, and I’ve forgotten a lot. But I still understand the basics. Don’t count on me adding something here that I don’t work with on a daily basis.

But you can share your knowledge; in return, I can post a link to your LinkedIn, share training materials. Maybe even give some advice.
