Primary and Media Server instances are running on 5250 Flex Appliance with NBU version 10.2.0.1
MySQL Client Details:
OS Version : Linux 8.8
MySQL Version: 8.0.32
With NetBackup Client 10.2.0.1 installed on the MySQL Client server, DB discovery fails.
However, if we downgrade NetBackup Client version to 10.1.1, DB discovery works.
I have attached ncfnbcs log in the post.
It seems to be a problem with MySQL installation/configuration method.
If the installation was done using native Oracle Linux repositories, DB discovery only happens with NBU version 10.1.1
It works if the installation was done using mysql80-community repository with NBU version 10.2
