As extra info, this is the kind of logging I talk about: https://docs.oracle.com/middleware/12212/biee/BIESG/GUID-BC51D576-D373-4EEF-8C09-47FD10127F68.htm

As you can see the writer implementations aren't many, not much more than logging in a file or standard output. It isn't like a Java logger which could more easily write in a database directly.

But, if you have an Oracle database, you could try to read the file directly there. If you set it as XML output you have good chances to be able to define the log file as an external table and query it (just don't sure how it will deal with the constant writing to that file). So it's either manual scripting, or database work or use one of the many tools on the market (or opensource) to deal with log files, parse them and write them somewhere else.
