The nbmariadb.conf configuration file
The NetBackup for MariaDB (nbmariadb.conf) configuration file contains the parameters for the respective operations. It contains predefined settings and is located on the client. You can configure the parameters in the nbmariadb.conf file or provide them on the command line, where the command line parameters take precedence.
The nbmariadb.conf file keeps you from providing the parameters every time you run operations. When parameters are not configured in the nbmariadb.conf file, then the default parameter value takes precedence.
The nbmariadb.conf file is located in the following locations:
(Windows)
C:\Program Files\Veritas\NBMariaDBAgent\nbmariadb.conf.(Linux RHEL and SUSE)
/usr/NBMariaDBAgent\nbmariadb.conf
Starting from NetBackup 8.2, the nbmariadb.conf file is not created by default when you install the agent on RHEL or SUSE. The existing configuration file is prevented from getting overwritten as the RPM installer simply overwrites any existing files in the destination directory /usr/NBMariaDBAgent/.
If the nbmariadb.conf file does not exist, you can create the file by running the backup utility command without any options. For example, run the ./nbmariadb command. This command creates the default nbmariadb.conf file.
