Re: MS Defender for OL7 Oracle DB servers

Thats great to hear that it can work without any issues as sooner or later ask will come back again

We could not find the right combination which is not cpu hungry despite multiple calls with microsoft. I wish they have the real working combination published so we can try again.

My only question to your argument will be why oracle doesnt bundle it by default in 2022 for their exacs and exacc solutuons. Security is sold as major feature and malware protection is something they don't have on linux is a question mark for me
